How much solar panels save you.

For example in california where the cost of grid electricity averages about 17 97 cents per kwh the average price you ll be paying for your electricity with solar is about 7 cents per kilowatt hour. On average solar panels will save you over 1 100 per year on your electricity bills. In january 2018 president trump imposed a four year tariff on imported solar cells and panels that started at 30 and drops 5 each year. The estimate also considers the average sunshine available in the country and the average electricity price of 13 34 cents per kilowatt hour reported by the energy information administration.

The differential between these two numbers is significant. Most homeowners are paying about 1 5 per watt a 50 decrease from just a couple of years ago. A more universal way of looking at cost is to determine the cost per watt. Most solar panels are sold for about 0 70 per watt if bought in bulk.
