Just last week, the average price of a gallon of unleaded gas in St. Louis was $3.20. By Monday, the average price for regular gasoline on the Missouri side of the St. Louis region reached $3.59 a gallon, according to AAAâs Daily Fuel Gauge Report. Thatâs up 28 cents from this time last year.
But, by 2016, Deutsche expects solar energy to reach price parity in all 50 states. For example, the cost of solar-generated electricity in the top 10 states for capacity ranges from 11-15 cents per kilowatt hour (c/kWh), compared to the retail electricity price of 11-37 c/kWh.
So what is the current cost of residential solar power? As of early 2015, itâs approximately $3.00 per installed watt. The average sized solar panel system is 5,000 watts, so this brings the total cost to $15,000. That 15k figure is just an average amount.he large solar leasing companies are still charging $5.00 to $6.00 per installed watt or more, but their customers only see the lease payment. They simply have too much overhead, advertising costs, and investors seeking a good return on investment to offer a fair price on solar power.
