Introduction: 90V 60W Solar Panel
In this video we show how we built the high voltage solar panel we custom made to charge the 72V 2kWh li-ion battery installed in the Nobuo-01 electric Kart.We used 14 protected 6Vmp cells connected in series. For bigger installations in series you need to add bypass diodes in each cell (or panel in series) in order to avoid a shaded cell become a resistor.In our case we used a PWM solar controller but if the voltage of the finished panel is appreciably greater or lower than you battery voltage you need to use a MPPT controller*info: https://www.facebook.com/evmadrid1
We have a be nice policy.
