Solar Rhode Island
Our sample assumes a 10 KW solar PV installation and installed cost of $3.00 per watt. This keeps the math simple and allows you to estimate your own needs for your own property based upon electric bills.
Providence gets on average 4.7 sun hours per day. Using a 10 KW solar PV system one could expect to produce about 12,986 kWh annually, or 1,082 kWh per month which is almost double the average home usage of 586 kWh for the State. Estimated Annual Savings would be $1,849. At a $30,000 total cost to install your simple payback is in 16 years.
The above payback calculations do not take in to account any incentives, State or Federal
