How much power does a 300 watt solar panel produce?

1. Design guide for 300W small off-grid solar system (12V battery system)


A. 1*300W Mono/ Polycrystalline solar panel.
B. 1*30A Mppt solar charge controller.
C. 1*100AH 12V Gel or 1*50AH LiFePO4 battery.
D. 1*300W pure sine wave inverter.

How much power does a 300 watt solar panel produce?

With an average daily sunshine of 5 hours at full load, this system can generate approximately 1.5kWh, calculate the power generation of this solar panel according to the local sunshine situation. Without using the load, the 12V 100AH battery can be fully charged in about 4 hours. Assuming that our system is used for outdoor monitoring, usually a set of monitoring power is 20W, which also means that the power consumption for 24 hours  is 0.48kWh. Because the inverter has a conversion efficiency, we calculate it at 88%, the 20W monitoring consumes about 0.55kWh per day. If you are in a place where there are 10 hours of daytime, this system will fully meet the daily monitoring work and even can support more than 48 hours in  the absence of any sunlight. If you need a longer time or larger load, you can increase the battery capacity. And the cost of this system is very low, suitable for off-grid solar power system with only low-cost budgets.
