Solar power off Grid systems
Before selecting the elements you must calculate something your load, how much time it'll operate etc.If any one know basic maths then It is simple to calculate.
1 .Decide exactly what appliances (light, fan, tv etc ) you wish to operate and just how long (hour).
2. Start to see the specification chart in your appliances for energy score.
3.Calculate the watt-hour which can be equal to product of energy rating of devices and time ( hr) of run.
Allows you to wish to operate a 11W CFL for 5hour from solar power, then watt hour is equivalent to
Watt Hour = 11W x 5 hr = 55
4.Calculate the total watt-hour : Just like a CFL determine the watt hour for the devices and include them together.
CFL =11W x 5 hr = 55
Fan = 50 W x 3hr = 150
television = 80W x 2hr = 160
Complete Watt-hour = 55+150+160 = 365
Today the load calculation is over, the next thing is select the right components to match together with your load necessity.
