The solar calculation for home Step 1:- Home electrical load calculation? Step 2:- Inverter Selection? Step 3:-Battery Selection? Step 4:-Solar Panel Selection? Step 1:- Home electrical load calculation? 4 Led Light    = 4×25 = 100W 2 fan              = 2×80 = 160W 1 Tube Light = 1×40 = 40W 1 Led TV        = 1×50 = 50W Total Load = 350W Step 2:- Inverter Battery House Load: – 350W Consider – 500W However, the Recommendation is 800-1000W best AC load =350w Battery DC Volt = 12V DC current required P = V x I I=P/V 350W AC Load …DC current required (I) =29.17=30A Step 3:- Battery Size Selection in AH Formula:-W x H/V Where: – W= Total load (350w) H= Backup time in hours (8) V= Battery voltage (12v) =350X8/12=233AH Battery Standard: – 250AH Battery Select: – 250AH Battery Charging Current We will calculate the charging current for the 250AH battery. As we know the charging current should be 10% of the AH rating of the Battery. Therefore Charging current for 250AH Battery                        = 250X10%                        = 25A Step 4:-Solar Panel Selection? Solar panel Current =Battery charging current + Home load current                                    = 25+30                                    = 55 A Solar plate power Formula = V X I                 = 12 X 55                 = 660W 340W Home load (AC) = 660W Solar panel required DC The 660w Solar panel below is available in the market. No. of solar plates =Total solar plates watt/single panel watts =660/180 = 3.66 Approx. (4) No. of solar plates:-4 panels (4x 180w) 350w home electrical load Inverter: – 800-1000w Battery: – 250Ah Solar panels: – 4 X 180w
