What Affects Solar Battery Storage Efficiency?
When sunlight strikes the solar panels, they convert the sunlight into direct current (DC) electricity. As a home draws on the energy, the solar panel system''s inverter converts the electricity into usable AC (alternating current) electricity. Any energy generated by the solar panels and not immediately used is stored in the solar battery.
PV Panel output voltage
Panel temperature will affect voltage – as has been discussed in another blog. Have a look at these I-V (Current vs Voltage) and P-V (Power vs Voltage) charts for a 305W solar panel from Trina Solar. You can see in the P-V curve that as the solar radiation decreases from 1000W/m2 to 200W/m2, the power drops proportionally – from 300W to 60W.
