There are a few things that are more annoying than when you get up in the morning,But your solar panel display shows low power, even if the sun shines.Even worse,Your battery is low.What happened, how do you find the problem?This is especially important if you are in your mountain shed or farm and extra power is really needed from your solar system.Usually solar cells and arrays are very reliable, stand up, weather extremes, and even hail if properly constructed.Fortunately,There are very few problems with solar panel systems,But the fault may happen.So you need to be able to find possible failures.There are some faults,They need to be corrected as soon as possible because they can break other parts of your system and put them under improper power loads.We will assume that your array has been working properly for some time.Also,This power drop has become very sudden or unexpected.Similarly,No cloudy days,No one has been secretly occupying power.Unfortunately,We don't have enough space in this article to solve the controller or inverter problem.If your solar array is a commercial, "ready-made" systemIt's probably the best to pull out the manual and read their diagnostic section.Otherwise,Pick up the phone,They should have all the answers to your question.However,If your array is a DIY solar panel project then let's get started.Let's assume that you have checked the obvious,Like someone did not capture and pull out a panel output resulting in a ladder,There is no bullet hole in your array, there is no pile of leaves on the solar panel,Especially in autumn.While autumn is beautiful, it can be a hassle to make sure the panels still don't have those beautiful leaves,Especially if you're in the woods.Before you get around your system?Keep in mind that your array generates electricity, so take care of your safety properly.If you're not confident,Get professional assistance.Please be careful,Throw out the power isolation switch,Even better,Remove the battery terminals.Remember,You can put a punch in your battery.It is very dangerous to short-circuit your battery terminals.So,Here is a simple list of solar panels for you:Once we check the basic systemWe need performance through the panel.Disconnect the array and check the output lead,The current flows.If it's running properly, the power supply is good,Go back and check your controllerInverter system,Electrical and electrical appliances.Over-If you're in a hot place,You may have just experienced overheating of the panel.In very hot places and the hottest parts of the day,As the battery runs outside the optimal temperature range, the voltage of the system drops.This is normal and they recover once they cool down.A typical 18 v photovoltaic cell is designed to work around 17-18V at 25C.So,You should still get about 12 V even if their efficiency drops at higher temperatures.If your "get off" is worseIt is then likely that it has a weak photovoltaic cell or faulty electrical connection somewhere in the array.The thermal expansion of corrosion and connection can increase the resistance to cause the output to drop.Try cooling the array,Either shade it for a while or pour water into the array (On the cover).Once cool,Your voltage should be back to normal.but if not,Use the coloring test to find the failed cells.Before you start unpacking the panelWe can locate the faulty unit or wiring part by simply coloring the part of the panel.By coloring about 3 or 4 cells at a time,You should output an array less than half.Disconnected from the panel,Monitor the output using a multimeter or a test load such as a small fan.If you cover the area of the panel,Power will not fall,The cells in this panel area then do not work properly.Take a closer look at the labels and wiring joints for all the family cells nearby.Any signs of corrosion can be at the root of the power supply problem.This needs to be corrected quickly before you damage the cells to overheat.The additional resistance of the faulty solder increases the load and resistance at this point,An overheated cell until it fails.Except for visual inspection of all connections,Coloring tests can be used to locate affected cells that may have welding problems.If moisture enters your panel,You have a real problem.Water will start to corrosionAffects all electrical connections.If you happen to live by the SeaSalty and humid air will soon erode electrical connectionsAnd aluminum frame.Moisture can also cause distortion of wood,The distortion of the wooden panel container can break the label connection and even crack the cells.If possible.Go for an extra fee and seal the panel using aluminum or perspex.You will need to replace all the metal parts and connections that are corroded or oxidized and you find.Although not common,Blocking diodes can start to fail.Most photovoltaic arrays use blocking diodes to prevent the array from discharging batteries at night.In this case,You may find that there is no clue to the power output at all.Once you check all the other possibilitiesDo a diode test.If the diode failsReplace the diode,Or if it's in a remote location,Remove the diode from the circuit until it can be replaced.BUT,Remember to disconnect the panel at night until you can replace it or you will run out of your battery.In another note,I 've come across people who cut costs, "gang", a couple of smaller diodes that match, "blocking amps ".It's a problem waiting to happen and you shouldn't do that.A proper rated diode must be used.Otherwise,The current will flow through the lowest resistance point,i.e.The smallest diode until overheating and failure,The current then flows to the next diode until it fails and so on.Ultimately, the whole thing shorts and blows your system with serious risks,And it's a fire hazard.If you need a diagnosis on how to test the blocking diode,Feel free to visit our website for instructions.As we mentionedSolar panels are usually very reliable,Even if it is cloudy or snowy,If they take care of it properly and keep it clean.Moisture is your biggest threat.So let them seal.Good luck,May your panel continue to power you.
