Today we started a new season with our RC models on the airfield. Days are now longer and the Sun provides more energy to the off-grid system which is powered by one standard sized solar panel.
Nominal peak power (Pmax): 225 W Maximum power voltage (Vmp): 30.2 V Maxium power current (Imp): 7.44 A Open circuit voltage (Voc): 36.6 V Short circuit current (Isc): 8.06 A
For storing captured energy we use Panasonic LC-XB12100P battery with a capacity around 100 Ah and some spare car batteries with the capacity around 55 Ah, thus total capacity is 200+ Ah.
Last year the MPPT tracer 1210a provided 127 kWh and today it juiced the battery to 13.8 V which is considered fully charged.
