The factors that could contribute to a low power problem are: This is possibly the most common cause of low voltage. Ensure that there are no trees around and that the solar panels are not blocked by shadow at any time during the day. Keep in mind that a solar systems lasts for more than 25 years and trees grow over time.
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.
It’s also possible that one solar panel in your pv array failed. As the pv modules are connected in series, one failing pv module will shut down the entire system. If your solar system is not delivering sufficient power for which it is rated for, the resulting situation is called a low power situation.
These two conditions which may require troubleshooting are: Zero output is a common problem and in nine out of ten cases, it is due to a faulty inverter or charge controller. It’s also possible that one solar panel in your pv array failed. As the pv modules are connected in series, one failing pv module will shut down the entire system.
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.
