Technical FAQs 4

How to check if a solar panel is set at 45°?

The panels are set at 45°. Never connect your panel in series. Yours is a 12v system and will get damaged with higher voltages. If it is connected to batteries, then the mentioned voltages are correct. If you want to check and don\'t have an engineer around, you can disconnect the battery terminals and check. The voltage may go upto 20v

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.

What happens if a solar panel fails?

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.

How long do solar panels last?

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.
