Projects › Projects › how to build solar panel arrangement to place on the roof of the house › solar panels you will get
solar panels you will get readymade. depending upon your load requirement you have to calculate how many solar panel you need.
you can build your own battery carger circuit and inverter circuit.
first calculate the required electrial load that you want on solar energy
based on that design inverter circuit with battery
next is to build charging circuit for battery from solar panel
and from that you will get how many solar panles you require
