Home > News & Events Some Knowledge About Solar Panel

When we need battery charging, the output voltage of solar panels must be higher than the current voltage of the battery, if the voltage is lower than the battery voltage of solar panels, then the output current will be close to zero. Therefore, in order to be on the safe side, when in solar panel manufacturing factory, the peak voltage of solar panels (VPP) is around 17 v, this is when the environment temperature is 25 ° C set of standards.


Solar Panel
This set of reason, (interesting is that we are different from ordinary people's subjective imagination, the following conclusion may be surprised us) when the weather is very hot, the peak voltage of solar panels will VPP to around 15 v, but in the cold weather, the peak voltage of solar energy VPP can reach 18v!

Hanfong new energy is a dc to ac inverter manufacturers and professional in photovoltaic industry. And yes! They also provide solar energy product like solar panel, solar charge MPPT controller and battery.
