Day by day the price of the solar panel falls gradually.But still installation of a complete off grid solar system is costly. So I write this instructable to get all the components of your solar system separately and assemble it all by yourself.
If you are decided to install a solar panel system to cover your home power needs.This tutorial is for you.I have tried my best to guide you step by step from buying different components to wiring everything by yourself.
Only you have to know some basic electrical and math for designing the entire system.Instead of this I have attached links of my other instructables to make the charge controller and energy meter.
For a off grid solar system you need four basic components
Besides the above components you need few more things like Copper Wire, MC4 Connector,breaker,meter and fuses etc.
In the next few steps I will explain in details how you can choose the above components according to your requirement.
Note : In the picture I have shown a big solar panel of 255W @ 24V , two batteries of 12V @ 100Ah each, 30A @ 12/24V PWM solar charge controller and a 1600 VA pure sine wave inverter.But during the calculation I have taken a smaller solar system example for better understanding.
