Solar works simpler than you think …
Firstly, we need to understand the terminology
1. Solar Panels
A solar photovoltaic (PV) cell is a semi-conductor device which converts solar energy into electricity. Solar panels are made of photovoltaic cells that convert sunlight to direct current electricity (DC electricity). As long as sunlight hitting your panels, they are converting solar radiation into DC electricity.
Inverter is a device that covert the DC electricity produced by your solar panels into alternating current electricity (AC electricity).
3. Electrical Panel
The AC electricity from your inverter flows to the electrical panel, and then into to your home where it powers your lights and appliances. It is commonly called a “breaker box”. If you generate more AC electricity from solar energy than you use, it flows into the utility grid and while you take in the credits.
4. Kwh Meter Export-Import
In order to measure the amount of electricity you draw from the grid, and how much excess solar electricity you push into it you need a Kwh Meter Export-Import.This meter is different from the usual meter you see, so you will need to contact your registered area utility company to get a meter replacement.
A Kwh Meter Export-Import looks like this:
