Do I have the correct understanding on calculating the savings?
My electricity is $.10 per 1kWh. If I’m on net metering than my power company will pay me $.05 per 1kWh.
Let’s say I use 20kWh per day without solar which costs me $2 from the power company.
Now, I install a solar system that produces 20kWh per day when the sun is shining.
Let’s say I used 10kWh during the day when the sun was shining and I send the extra 10kWh to grid earning me $.50 credit.
Now the sun stops shining and I start drawing power from the grid for the 10kWh that I need to power my house.
I use up my $.50 credit built up from my solar panels to pay for 5kWh. Then I have to pay $.50 for the remaining 5kWh.
To be 100% covered I will need to buy a system that will produce 30kWh per day.
