Obstructions, dirt, a faulty inverter, or broken panels could be why your solar panels aren't working. It's fairly easy to clean solar panels or remove obstructions to get them back to their previous performance.
Trusted Trader Elltec Energy Services. If your panels aren't producing any electricity when you'd expect them to, it's most likely a fault with the inverter or problem with the wiring. Occasionally the generation meter might fail. If this happens, you'd see no recorded generation, even though the system is working.
The build-up of dirt, dust and mould is a common reason for poor system performance and will reduce the power output by 5 to 10% on average. A build-up of dirt or bird droppings on one or more panels can have an even greater effect and cause hot spots if one or more solar cells are partially covered, causing a reverse current.
Nearly seven in 10 owners had had no problems with their solar panels in our survey of over 2,000 owners.* The most common – and most serious – problem owners face is with the inverter. In some cases inverter problems mean you don't get any usable renewable electricity. It can also be a pricey problem to fix.
To effectively troubleshoot solar panel problems, a systematic approach to diagnosis is necessary. By following these steps, you can identify the root causes of issues and take appropriate actions: Begin by conducting a thorough visual inspection of your solar panels.
Another potential cause of insufficient power generation is a faulty solar inverter, which converts the panels' direct current (DC) generated into usable alternating current (AC). Additionally, inadequate system sizing or incorrect panel orientation can impact power generation.
The most common cause of low power output in solar panels is obstructions or shadows on the array. Checking Voc (voltage open circuit) and Isc (current short circuit) measurements can help diagnose panel issues. Loose connectors and improperly seated terminals can cause low voltage or current output.

The box looks well designed and sealed from elements but is pretty easy to take apart. Inside we find one board and a few flex cables to display/buttons membrane: There is a hidden USB Host socket next to RJ45 connector that is not brought outside. Might be handy. Also a few debug headers in the lower left. While I had the board exposed, I took a look at components-see block diagram below. It's basically an NXP I.MX253 system with the usual PMIC/memory bits/ETH PHY and an ST7540 FSK. I still do not know for sure what the failure was and whether I did really fix it vs just gotten lucky on reboot. I guess time will tell. I can always go chasing console output later. It's a shame that.
The article emphasizes the importance of the solar charge controller in an off-grid solar system and discusses common issues and troubleshooting methods. It explains that a malfunctioning controller can lead to battery damage or reduced panel output. Troubleshooting involves checking battery voltage, panel orientation, and cleanliness.
One of the main reasons solar panel charge controllers fail is that they overheat. To prevent this, make sure the charge controller is installed in a cool, dry location. Avoid locations that are exposed to direct sunlight or near heat-generating appliances. This will help prolong the life of your charge controller.
The main culprit is usually a solar panel with a high output voltage. When the output voltage of the solar panel is more than the maximum voltage limit of the controller, it can cause all sorts of problems. The most common one is that the controller will switch off automatically to prevent damage.
The most common one is that the controller will switch off automatically to prevent damage. This problem can be caused by a faulty solar panel or a controller with a too low voltage limit. If you see that your controller keeps shutting off, then check the output voltage of the solar panel. The voltage should be between 18 and 22 volts.
If you find a tripped breaker, you will need to reset it. If the problem persists, you may need to replace the breaker. Otherwise, your charge controller will keep tripping the breaker. If you want to keep your solar panel charge controller working properly, you can do a few things, including:
One of the biggest factors in solar panel degradation is high voltage. When the battery voltage is too high, it can damage the cells. This is why most solar panel charge controllers have a maximum voltage limit. When the battery reaches that voltage, the controller automatically shuts off the load to prevent damage.
