FAQs about Solar power supply is on but not generating electricity
Why is my solar system not generating electricity?
A solar system not generating electricity can be attributed to various factors. It is important to address these issues promptly to maximise the benefits of solar power. Check for shade coverage and consider tree trimming, ensure your panels are clean, monitor the performance of your inverter, and ensure the proper installation of a solar meter.
Why do solar panels have a low power output?
Conducting a bi-annual survey of the installation site is a good idea. If shading is not an issue, most likely it will be the higher than normal operating temperature of the solar panels. It has been scientifically proven that the voltage drop rises with the rise in temperature. The higher the temperature, the lower will be the power output.
Why does my solar system have low power?
The factors that could contribute to a low power problem are: This is possibly the most common cause of low voltage.

Keep in mind that a solar systems lasts for more than 25 years and trees grow over time.
Why is my solar panel not working?
This may be the result of a hotspot that may occur when micro cracks appear in the cells. The result is a lower voltage in the panel, which will bring the overall voltage of the solar array down. An increase in resistance is also likely to happen in a junction box that may be exposed to moisture.
How to reduce power output from a solar panel?
The higher the temperature, the lower will be the power output. Adding more modules in series, and therefore increasing the string voltage, will eliminate this problem. Also, make sure that there's sufficient air circulation beneath the panels and that this open space is not blocked in any way.
Why is my solar inverter NOT working?
