BC Hydro Self Generation for Solar Energy - How it Works

 
Step 1
–

Solar panels convert energy from the sun into direct current (DC) electricity, otherwise called solar PV generation.

Step 2
–

Inverters convert DC electricity into alternating current (AC) electricity, which is what a home and the BC Hydro grid uses.

Step 3
–

The solar PV generation powers the home first, with excess PV generation being sent to the grid.

Step 4
–

Your smart meter measures how much grid electricity has been used by a home, and how much excess PV generation has been sent to the grid. 

Step 5
–

Excess solar PV generation is credited on the BC Hydro bill. Homes with solar energy systems tend to bank credit through the spring & summer and use it up in the fall & winter.
