The amount of credit depends on the size of the solar power PV system installed at your site.
Here are several examples**
A single family home with a very typical yet small 2 KW system, the annual deposits on the energy credit card could be over $400.
To determine the amount of credit for a single story home, assuming a regular sloped roof and good sun exposure for a majority of the day, you can use the square footage of the house itself.
For example given a 2500 square foot home, a good estimate would be 625 square feet of space for solar panels. The size of the solar PV system would be approximately 6.25 KW. The annual deposits on your energy credit card would be around $1200.
An apartment building in Pleasant Hill, California has 100 apartments for low-incomes seniors. A single 175KW solar PV system installed would bring over $35000 per year onto the energy credit card or $350 per apartment per year. These moneys would help each tenant with energy efficiency upgrades, bus tickets, etc.
Warehouses with 17,000 square feet for floor space . The annual deposit on the energy credit card for that owner and tenants would total $17,000.
A very large shopping mall with a 1,000,000 square feet of roof space for a 5 MW solar PV system, the annual deposits on their energy credit card would be approximately $1,000,000.
