Solar power System Design

There are many types of solar power packs depends on there power ratings like: 

• 200 W (day pack)
• 200 W (day+night)
• 200 W ( night pack)
• 500 W (day pack)
• 500 W (day+night)
• 500 W (night pack)
• 1 KW (day pack)
• 1 KW (day+night)
• 1 KW (night pack)
• 2 KW (day pack)
• 2 KW (day+night)
• 2 KW (night pack)...............................................................

Electrical units(KWh) to be save per day:

any solar power system can save maximum units per day four times of there power rating in KW like:

1 KW solar power system can save Maximum units per day = 4*1 KW

                                                                                            =4 units/day

Designing of solar power pack:

• 200 W (day pack):

 It can save maximum  0.2*4 = 0.8 units /day

and it can work properly only in day light because in this system we will using battery backup only for a small time.
