Basic Components of Solar System
Solar Panel
Solar Charge controller
Inverter
Battery Bank
Load Calculation
03 energy saver (24 watt) 24*3 = 72 watt + 08 = 80 watt
02 Fan (100 watt) 100*2 = 200 + 20 = 220 watt
Load = 220+80 = 300 watt
If u want to use it for 06 hours
300 * 6 = 1800 watt
Solar Cell
Mono
High efficiency
Low space
Long Life
Better Performance at low light condition
Poly
Less expensive
Solar panel calculation
Average sunlight duration = 07 hours
Total required energy = 1800 watt
1800 / 07 = 257 watt + 128 (50% extra) = 385 = 400 watt panel
Battery
Dry Battery
High cost
High performance
No Maintenance
Liquid Battery
Low Cost
Low Performance
Maintenance required
Total energy for 06 hours = 1800 watt
1800/12 = 150 A + 50 = 200 Ah
Inverter
Use to convert DC to AC
Running Load 300 watt
500 watt inverter is good
Charge Controller
Its function to control Solar charging process.
It also stop complete battery discharge.

Apologies for the issues with focus towards the end of this video. Still getting used to the new camera, and the auto focus doesnt work entirely as I would like. Anyway, enjoy!
