00 Watt Solar photovoltaic panels how many hours a day
2, solar photovoltaic power generation system is the use of photovoltaic effect of semiconductor solar cells, will be directly converted to a new generation of electric power system with solar radiation, operate independently and grid connected in two ways.
1, assuming that the 70% is the charging process, the actual use of solar panels.100 (W) x 0.7 x (H) =70WH=0.126 degrees (1 degrees = 1 kW x 1 hours)
Stand-alone PV system requires a battery as an energy storage device, mainly used for non grid in remote areas and scattered population areas, the system cost is very high; in the regions with public power grid, grid connected photovoltaic system grid connected operation, save the battery, not only can greatly reduce the cost of environmental protection, but also has a higher performance the power generation efficiency and better.
