How to Wire Solar Panels in Parallel

If you are going solar for your home or business, it is important you know why and how to wire solar panels in parallel.

Mark just switched to solar energy as an alternative energy option. With all the talk about renewable energy and climate change, he decided to ‘go clean and green’ with his home energy supply.

He is finding it quite confusing to understand how to install the system in his home. Mark isn’t sure he needs to learn how to wire solar panels in any specific way: parallel or series. This is because to him, once the connection provides electricity, it’s all good. But is it?

Well, I‘m so not sorry to burst Mark’s bubbles, and yours too if you think the same way. How you wire your solar panels matters. It is one of the most important variables in your solar energy system. It determines the overall efficiency of your system and also affects the kind of equipment you would have to buy alongside it.

For one, your choice of inverter is based on its current and voltage rating depends on how your solar panels are connected: series, parallel or both. I’m sure you want the best option for your home, right? This is why you have to take note of this.

For those who are still in the dark as to what solar energy, solar panels, inverters and all the jargons we have just discussed, no worries. I got you. Let’s take a run down through the basic concepts. Shall we?

What is Solar Energy?

Solar energy is the most available energy source on earth. It is clean, renewable and cannot be used up. Solar energy is increasingly being integrated as an off-grid energy option in homes and offices. This is well in line with the Sustainable Development Goals for 2030, which targets a substantial increase in the share of renewable energy in the global energy mix as well as an improvement in energy efficiency globally.

Functions of a Solar Panel and Solar Energy System

A Solar panel is a very important component of the solar energy system. It is responsible for trapping sunlight and converting it into electrical energy. The panels are made of Photovoltaic cells or PV cells. They are spread about on the surface of the panel boards. When sun rays fall on these cells, they are converted to electricity. So, the more the panels, the more PV cells are available to generate electricity. This electricity is Direct Current (DC). However, most of our commonly used electrical equipment make use of Alternating Current (AC). An inverter is then connected to the solar panels. Inverters are electronic devices that convert DC to the required AC needed to power electrical devices. So, we have our needed current and so our system is set up, or is it? There is still one more thing.

We also need batteries in our system. Since we do not have the sun in full intensity at every time of the day (of course night comes and the sun retires to bed), we cannot guarantee that we would always be able to constantly produce a certain amount of electricity. Also, during cloudy days and also in the winter, the many clouds that form in the sky reduce the intensity of the sun reaching us. This means that much electricity can be generated from our solar energy option. This is where batteries come in. Batteries help us store the energy generated for future use. During the day when the sun is at its peak, you can use electricity in your home and be rest assured that by night, you’d still have electricity running so you can continue from where you left off the Game of Thrones episode before work. I see it like a kind of savings account or piggy bank, where you save energy for the rainy day (pun intended).

How Do You Increase Efficiency and Power of Your Solar Energy System?

To increase the efficiency and power output of your solar energy system, it is advised that you buy more solar panels. When you have more solar panels, the ideal thing to do is to connect them. This is pretty much obvious. Now here’s the catch. Well, panels are not connected in just any way. All the types of connection are aimed at achieving one main purpose: to increase power output. However, each method employs a different strategy in doing this. We will see this as we proceed.

Ways in Which Solar Panels Can be Connected

There are three ways solar panels can be connected:

  1. In Series Circuit
  2. In Parallel Circuit
  3. Compound circuit (Series-Parallel circuit)
Series Wiring of Solar Panels

What does a series connection mean? Well, whenever electrical components are connected in series, the aim is usually to increase the voltage of the circuit. Solar panels connected in series produce a combined total voltage of the sum of individual panel ratings. What this simply means is that if you have six 12 volts 5 Amperes panels connected in series, your total output would be 72 volts 5 Amperes (Amperes is the unit used to measure current).

Series connection creates a single pathway for current to travel, which means that all the current must flow through all the loads (in this case the solar panels) in the circuit. This is why the current remains the same up to the output. One other characteristic of series connection is that when the circuit is cut at any point, the entire system stops operating. This is pretty much expected since the same current goes through all as we have seen, so cutting off one is stopping current flow in the circuit.

Solar panels have negative and positive terminals. To connect panels in series, you connect the negative terminal of one to the positive terminal of the next. This way you can increase power without altering the value of current being fed into the inverter. A very common example of series connection is your TV remote control. Also, a string of Christmas lights too is connected in series. The lights would not come on if one of the bulbs is burnt or not in place. Current path, remember?

Parallel Wiring of Solar Panels

Parallel connection, on the other hand, provides multiple pathways for current to travel within the circuit. This is the most common of all types of electrical wiring. I’m very sure your house is wired the same. Want to know how? Your home has a primary point where electricity enters into the house. It is from this point that electricity is fed to different sockets, bulbs, heaters in your home. When your friend comes visiting and you turn off the microwave after heating your lunch, it does not also turn off the TV in the living room. Like we saw in series connection, one point in the circuit going off means the entire circuit goes off too. This is not the case in parallel wiring. Since we have multiple current paths, one path going off does not affect the other(s). This means that parallel connection allows for redundancy, that is the system is more reliable as a fault in one path does not affect the whole.

What Are The Advantages of Connecting Solar Panels in Parallel?

Aside from improving the reliability of systems, parallel connections also aim to increase the amperage at the solar panel output. This means more current is being fed to the inverter. So, taking our example of six 12 volts 5 Amperes solar panels, parallel wiring would produce an output of 12 volts 30 Amperes. If a consumer has an inverter with a DC input rating of 12 volts, then such consumer only needs to supply 12 volts from the solar panel for the inverter to function. In this case, the consumer can connect in parallel to increase the amount of current, since the panels are wired to feed in 12 volts. This way, power can be increased without going past the voltage limit of the inverter.

How Do You Wire Solar Panels in Parallel?

Mike and Tim live together and have decided to get a solar panel. They split the bill and both agree to buy two panels each when they return from work. Later that evening, they discover that they have bought dissimilar solar panels. There has been an argument all evening, and it looks like work was tough on both of them. Well, I can help.

Connecting Similar Panels

If you are wiring similar solar panels in parallel, it is pretty much straight forward. You connect all the positive terminals together into one terminal and all the negative terminals together too. So, I could convince Tim to go back with his and get one that matches Mike’s and then, case dismissed.

Connecting Dissimilar Panels

If Tim is hell-bent on keeping his, and Mike is not bending, they have science to thank that they can reach a compromise. When solar panels have different wattage but the same voltage, they can be connected in parallel. Wattage just means how much power is measured. If the voltage is constant, we can connect them just as we did the first instance. What that simply means is that current is the variable factor in the different panels. For parallel connection, once the voltage is the same, we are good to go.

Had they each bought panels with different voltage ratings, well one person would surely have to give in because there is no way we can connect them in parallel.

Solar Panels Connected in Compound

Well, Tim and Mike’s case didn’t fall into any of my predicted events. Tim bought two 6 volts solar panels while Mike got two 12 volts panels. Well, science to the rescue! We can connect the two 6 volts panels in series to get a 12 volts output. We can then connect this result to Mike’s 12 volts panels and everybody is happy. This is called compound wiring of solar panels.

Conclusion - How to Wire Solar Panels in Parallel

It is important that you as a home or business owner are able to connect your solar panels yourself and understand what each type of connection entails. Parallel connection is the most commonly used type of connection and we have seen why. You can now make informed choices based on what is available to you and enjoy your solar energy option with maximum Returns On Investments (ROI).

Best Deep Cycle Batteries

Whether you are looking to install a solar panel in your home to go off-grid or stepping up your fishing game by getting yourself a boat, sooner rather than later, you are going to require a deep cycle battery. And unlike car batteries, many people have no understanding of deep cell batteries because they are not needed that often so if you are also one of those many people who have zero confidence while choosing a deep cycle battery for themselves. There is no need to fret. I have cherry-picked 5 best deep cycle batteries with help from my prior experiences and reviewed them in detail. You can read through each of the battery's reviews and figure out the one that will be the most ideal for you. How To Pick The Best Deep Cycle Batteries For Your Needs Before you dive deeper into the batteries' descriptive reviews, it is essential to know what features and attributes you should keep in mind when searching for a deep cycle battery in the first place. I have also inserted some questions here that people often ask while purchasing a deep cycle battery. You can check them out too. What to look for when choosing the best deep cycle batteries? When buying a deep cycle battery, check the battery's capacity and always inspect whether its battery capacity will be enough to run whatever you want it to run smoothly or not. Also, see that if you are going to harness small output from the battery, there is no need to buy a large capacity battery. The high capacity batteries cost more, plus the extra energy would be of no use to you. What brand should you go for when buying a deep cycle battery? Some people skip this part because, to them, a low price is an utmost priority. But, I would never advise you to go for a shi*ty two-star brand to save a few extra bucks because the deep cell batteries manufactured with low build quality are not at all rugged and will hit you in the long run. All the deep cycle batteries I have recommended in this article are from reputable manufacturers. Even if you don't find any of these batteries suitable for whatever reason, you can buy some other battery but never cut corners and go for one without researching the brand's past reputation. What are the benefits of using a deep cycle battery? These are the advantages of using deep cycle batteries. They are lighter and less bulky than traditional lead batteries.There are no liquids required in deep cycle batteries.Low maintenance cost.Deep cycle batteries have less energy loss.These batteries charge at a fast rate.The batteries are durable and also have a long life span. How long does a deep cycle battery last? Deep cycle batteries are usually pretty long-lasting. You can use a deep cycle battery for up to six years provided that you take proper care of the battery and make sure that it is not getting damaged during the charging process. You can learn more about the maintenance structure of deep cycle batteries here. Can you use a deep cycle battery in your car? The clear answer to this bizarre but frequently asked question is a big NO. A deep cycle battery can not produce enough power to start up your car in the first place, and even if you manage to run your car somehow because of a small engine. You will not be able to make it far, and the battery will lose its life in a very short time, so it is not practical at all to use a deep cycle battery in your car. At what amperage rate should I charge my deep cycle battery? Usually, these batteries are charged at more than 6 amps. However, there is a different rating recommended for every battery, depending on its size. I would recommend you check the label on your battery to get hold of the precise ampere rating you should charge your battery and if you can not find the rating on the label, then look for it on the battery's manual. Can you overcharge a deep cycle battery? No matter what type of battery you are using, overcharging is never a good idea. In fact, overcharging a battery can reduce the battery's life, so a good idea would be to disconnect the battery from the source once fully charged. What is the difference between a car battery and a deep cycle battery? The significant difference between a traditional car battery and a deep cycle battery is that the deep cycle battery discharges very quickly. On the other hand, a car battery takes some time to discharge. What is an AGM deep cycle battery? Put merely, AGM batteries can handle high temperatures, and also do not discharge faster like other deep cycle batteries. You can read more about AGM batteries here. How to identify a bad deep cycle battery? The best and easiest way to identify if a battery is bad or damaged is by charging it thoroughly and then using it. If the battery gives the output that is guaranteed by the manufacturer, then it means that the battery is probably fine. Otherwise, it would be best if you reconsidered buying it. To learn more about how you can identify a bad deep cycle battery, you can check out this article in which this subject is discussed in-depth.

How to Bring a Deep Cycle Battery Back to Life

If you are stumbling around to know, how to bring a deep cycle battery back to life, you are at the right place. I will explain to you in detail, how you can repair an old battery so that you can use it for some more couple of years instead of buying a new one. Deep cycle batteries are specially designed lead-acid batteries, known for maintenance-free and longer life span.  A normal car lead-acid battery gives a quick burst of current for ignition or other purposes. In contrast, deep cycle batteries are capable to provide steady current for a longer duration. Hence, deep cycle batteries are preferred in off-grid or hybrid solar power systems. If a battery is left unused for a longer duration, it produces sulphate crystals on the plates of battery cells. The sulphate crystal minimizes acid contact with the cell plates, resulting in rapid charging and short discharging time. This makes the battery ineffective or sometimes useless. Going straight away to buy a new battery is not a good option all the time. It will need an investment in new battery which is an expensive solution. In many conditions, you can recover the battery or enhance battery life for some more years. In a battery, there may be a sign of not holding a charge, or even not taking a charge, you can try to repair it to get more out of it. A series of steps are given here which you can follow to get your battery back to life. Precautionary Measures Before starting off with the repairing procedure, you must take these points in mind, Strictly follow the precautionary measures where discussed in the procedure.Use proper or appropriate tools for every job done with the battery.Battery inspection is very important procedure, do not overlook it in any case.While caps of the battery cells are open, try to avoid contact with electrolyte (water) inside the battery as it is acidic in nature.While charging the battery for the first time, pay attention to it regularly for first couple of hours. If body of the battery is too hot to touch, disconnect the charger immediately. Tools and Materials needed for the Repairing Process These tools will be used in repairing process while performing different steps. Battery chargerBattery DesulfatorBattery Load TesterFlathead or Phillips head screwdriverDry rag or a piece of cloth for cleaningBaking sodaDistilled WaterWrench or spanner for battery clamps Preliminary Inspection and Cleaning You will need to thoroughly inspect the condition of the battery. Check for any leakage in the battery because water level may go down due to leakage. Remove the battery terminals if they are connected. You should have two wrenches or spanners of correct size to loosen the battery clamps. In some designs of the battery clamps, you may need to use a flat head or Philips head screwdriver to remove the clamps. Battery terminals get corroded as the battery ages or due to environmental conditions. A white or greenish-blue powder forms at the terminals. You should use gloves and safety goggles while doing the cleaning as the powder is toxic. First, clean the battery using a dry rag or any piece of cloth. Add 3-4 tablespoons of baking soda in a glass of water. Then, use the solution to clean the battery surface with a piece of cloth. Inspect for the battery cell condition Open the cover or caps from the cells of the battery and check for the water level in each cell. If there is no or little water, then inspect for the condition of the cells as well. They should be at least moist, otherwise, there are chances of the battery destroyed. Look into each cell for the accumulated debris at the bottom. When the battery is dried off too much, the stuff from the plates is shed off and accumulated at the bottom. This stuff shorts the bottom of the cell plates and charging this battery is dangerous. Pour water in each cell of the battery Now, the time is to add distilled water in the battery. If the condition of cells is good, pour distilled water in the cells up to the given mark. If there is no mark given, try not to overfill the battery and leave some space at the top. Do not use tap water or water from any other source, no matter how clean it is. The reason is that tap water has different salts dissolved in it depending on the source of water. These salts enhance the process of corrosion in the cells. Put the Battery to Charging For first charging after the above treatment, use a slow charger of 1-2 Ampere to avoid any damage to the battery. If you do not have a slow charger, you can use a regular charger with precautions. Some intelligent chargers have a safety feature not to charge a deep-discharged battery as they consider a battery below 10.5 V as defective. Use a good battery in parallel if needed To deal with such intelligent chargers, you will need a good battery with voltages above 12 V and battery jumpers. Using jumper cables, connect the repaired battery in parallel with the good one i.e. positive with positive and negative with the negative terminal. Now, connect the batteries to the charger. The charger will sense the voltage of the good battery and will start the charging process. Keep an eye on the battery while charging Let the battery charging continue for about an hour. During that time, keep an eye on the battery if you hear any kind of hissing sound (gassing) from the battery. DISCONNECT IMMEDIATELY if you hear any hissing sound. After an hour, check whether it is slightly warm or hot to touch. If you feel that the body of the battery is hard to touch or hot, DISCONNECT THE CHARGER IMMEDIATELY. If it is slightly warm, then let the charging process continue. Batteries become a bit warm while charging. Remove the good battery if voltage improved If you applied the method of paralleling the good battery with the repaired one, remove the second battery (the good one) after 3 to 4 hours if your main battery’s voltages go above 12 V. To check the voltage, disconnect both batteries from the charger and disconnect them from each other as well. Now, using a voltmeter, measure the voltage on the repaired battery. If voltages are above 12 V, reconnect only the repaired battery to the charger. Let the battery charge for 24 hours. After that, disconnect the battery from the battery charger and measure its voltage again if they are satisfactory or not. Use Battery Desulfator to Remove Sulphate Crystals While performing the above charging procedure, if you find that the charging process is very slow or no charging at all, you will need a battery desulfator. Alternative names of battery desulfator are battery resuscitator, battery rejuvenator, or battery reconditioner. As it is explained earlier, if the battery is dried up too much or deep-discharged, sulphate crystals are formed on the surface of the plates of battery cells. We need to remove this sulphate from the battery cell’s plates. A battery desulfator is a device that enhances the capacity of an old lead-acid battery and extends the life of the battery. It provides pulses of high voltages or high frequency (depending on the technology used in the device) to the battery causing a current flow that reverses the crystallization process of lead sulphate. The desulfation process takes one day to three weeks depending upon the duration of the battery remain unused or damage caused to the battery due to the deep discharging. Perform Charge and Recharge Cycle It is a practice of experienced people to do the desulfation or charging/discharging repeatedly. Let me explain it to you. If you are doing the desulfation process, keep the battery on desulfator for two days, give it a rest for one day, and repeat the process. Measure the voltage at the end of each cycle and note if there is an improvement in the voltage. Repeat the desulfation process until you see no further improvement in battery voltage. Remember that disconnect the battery from the battery charger before measuring the voltage to get an accurate reading. In the same way, if you are charging the battery, charge it completely up to the limit possible and discharge with a load. This charging and discharging process help the battery to recover. Perform the Load Test In battery load testing, current produced by a charged battery is measured. We use this method to measure the health of a battery. First, you need to charge the battery until you get output voltage equal to the labelled voltage indicated on the battery. The voltmeter reading should be in the range of 10 percent of the labelled voltage. Connect the battery to the load tester and press the button to test the battery health. If the needle remains in the healthy (green) zone, the battery is in good condition. If you do not have a load tester, you can connect the battery to a random load like 12 V street light or headlamp of a car. The brightness of the light should not go down too early. Conclusion - How to Bring a Deep Cycle Battery Back to Life The recovery chances of a battery are 60 to 80 percent. The recovered battery can give an extended life of 6 months to 2 years depending on the amount of sulphation or damage to the battery due to overcharging, deep-discharging or battery heat up. A deep cycle battery does not need regular watering, a regular inspection is still recommended. It is recommended to use modern and efficient chargers, charge controllers or solar inverters which have options to care about the health of the battery.

How to Stop LED Lights Glowing When Off

If you are stomping your head off trying to figure out how to stop LED lights glowing when off, then stomp no more because in this article all the solutions to fix the problem have been explained. Shoddily manufactured LED lights, when turned off, often produce an afterglow. I have experienced this unusual behavior with the LED lights in my home too. At first, I did not heed much. Soon the rather abnormal phenomenon started annoying me, especially during my sleep hours. Hence I was forced to find a solution to fix this soul-sucking problem. With some help from a few professionals of the field and some internet research about LED lights, I was able to identify and resolve the issue. If you're also going through the same mind-boggling nuisance I was going through and also wondering how the heck are you supposed to stop already switched off LED lights from glowing, then you might want to keep reading because further in the article, I have explained all the fixes you can use to make the problem go away in as minimal technical terms as possible. What causes already switched off LED lights to glow? You must be left scratching your head while experiencing this weird occurrence of dimly lit LED lights for the first time, some are even left terrified, but before you draw any jigsaw conclusion, I am here to assure you that this is definitely not some devil's work. In fact, this behavior is triggered in LED lights by not only one but many reasons. Reason 1 LED lights are said to consume 25-80% less energy than incandescent bulbs. Usually, this high-efficiency factor of LED lights causes them to flicker because there is always some amount of energy left in the circuit after you switch off the light. That little energy is enough to light up the LED for some time dimly. Reason 2 Poorly done or old electrical wiring also causes the LED lights to produce an afterglow effect. The obsolete wiring does not affect incandescent bulbs. Suppose you have recently switched to LED lights on old electrical wiring. In that case, it could be a possible reason for the afterglow in the LED lights. Reason 3 If you are facing the afterglow problem in LED lights near a staircase or a hallway, then there is a high chance that two conductors connected in parallel might be causing the lights to flicker. Reason 4 Sometimes the light switch that you toggle to turn off the LED lights switches off the neutral conductor instead of the phase. This causes a low voltage drop in the phase, which is enough to pull the afterglow in LED lights. Reason 5 White LED light can produce an afterglow for several minutes due to phosphor. Phosphor is used in bulbs to convert the original blue light emitted from LEDs into white light because phosphor is of yellow color and the combination of blue and yellow creates white color. Things You Will Need To Stop LED Lights Glowing When Off Here is a list of things you will need to follow the fixes given below in order to stop LED lights glowing when off: LED lights from a reputable manufacturerNeon indicator lightZener diodeCompact fluorescent lamp (CFL)Screwdriver Keep trying the next fix until you achieve success in removing the afterglow. Replace The Flickering LED Lights A lot of the time, the LED light itself triggers the afterglow effect due to its low build quality or incompatibility with the electrical wiring of your house. So the first and the easiest solution I will recommend you to try to stop the flickering of the light is to replace that old light with a new LED light from a reputable manufacturer. If the flickering goes away after replacing the previous LED light with a new one, consider replacing all the flickering lights of your home to get rid of the problem completely. Install A Neon Indicator Light You can easily get a pre-wired neon indicator light from any electronics store or online through Amazon or eBay for a couple of bucks. But if you are on a penny-pinching streak or just feeling too lazy to even shop online, then you can also take out a neon indicator light from your old or knocked down kitchen appliances like fridge, blender, and kettle. You can carve the neon indicator light out of the appliance just by using a small screwdriver. Neon indicators usually last years till they burn out, so you should be well and good with the neon indicator light that you just took out from your junk. Once you have acquired the neon indicator light, install it between the neutral and line. What this placement of indicator will do is that the neutral indicator will act as a voltage soaker and will now glow instead of the LED. The light produced by a neon indicator is far less interrupting compared to that of an LED bulb. It is essential to check the voltage range of the neon indicator you are placing to avoid any burnout. Use A Compact Fluorescent Lamp (CFL) We have already established that LED lights often illuminate an afterglow due to some voltage present in the circuit. This residual voltage can be soaked by putting a compact fluorescent lamp (CFL) in the circuit. In this way, LED light will not glow because of no extra voltage in the circuit. It is best to consult an electrician when dealing with electrical wiring and circuits because of safety concerns. However, please make sure to turn off the mainline powering your operation site if you are performing it yourself. Place A Zener Diode Zener diode is a diode created mainly to help the current flow in the reverse direction. This diode can help you in overcoming poorly grounded wiring. You can easily get a zener diode from an electronics store or online at a relatively cheap price. Installing a zener diode is rather easy too, and does not require any special technical skills. Once installed, the zener diode blocks all the charge by regulating the voltage when the LED switch is turned off. Thus, there is no afterglow produced in the LED lights. Install A Different Dimmer Sometimes, the electronic dimmer you are using for your LED Lights is not compatible with them. This usually occurs when you replace your old lights with new ones but keep using the old dimmers with the new lights creating a compatibility gap, which leads to this afterglow. In this case, the best solution is that you should install new dimmers that are compatible with your new lights. Do a little internet research about your current lights, and you will find the dimmer compatible with them. You can also opt for an electrician to do this job for you if you want it to be done professionally. Connect Extra Capacitors Typically, in long hallways and stairwells, two conductors are connected in parallel. Sometimes, the voltage carrying conductor induces some voltage in the other conductor. This little voltage drop in the conductor is enough to trigger the afterglow effect in a switched off LED light. To get rid of this phenomenon, you can simply install extra capacitors in your lights. The extra capacitors will seep all the unnecessary voltage drop, eliminating the flickering or afterglow in the light bulbs. You can easily purchase capacitors from a traditional electronics store or an online one. In Case Of Automated or WiFi Controlled Lights In recent years, technologies like smart home automation, IoT, and more have taken off. Now people do not use their hands to switch off stuff, but instead, they ask Alexa to do it for them. So if you are also living with modern tech and use some fancy smart system to switch on and switch off your lights in your home, then the flickering LED lights problem in your home might be a little more complicated. The problem can be anywhere from your automated system to some deep electrical wiring connected to it. In this case, I would suggest you contact the company which installed the automated system in the first place. They would be able to diagnose and repair the problem in the best way possible because interrupting the deep electrical wiring yourself is dangerous and could also lead to electrocution. Summary - How To Stop LED Lights Glowing When Off People all around the world are switching from old bulbs to LED lights. The main cause of this switch is to take advantage of the low consumption and longevity factor of the LED bulbs. So if you are also one of those people who have switched from incandescent bulbs to LED lights, then your investment will definitely pay off. And in case you were regretful of your decision due to the flickering of the lights. No matter the situation, there is no need to fret anymore as this article contains all the solutions you can use to fix the afterglow effect. Now that you have all the solutions to solve the flickering problem, it is now time to get in action and do some work.
