The estimated cost to install solar at your house is $47,435. We calculated this because we think your electricity usage for the year is about 22240 kWh, and a 15.76 kW size solar system on your roof would replace 100% of your usage. We are using an estimated cost of $3.01/W, which we get from Energy Sage.
The current electricity costs for Baltimore Gas and Electric Co are 21¢/kWh. So, by replacing 100% of your usage, you’ll save $4,584 throughout the year. If the costs of electricity stay the same, then your savings will pay for your solar system in 10.35 years. If the costs of Baltimore Gas and Electric Co electricity rise 3%, then your savings will pay for your solar system in 10.05 years.
Solar installed at your house would generate different amounts of electricity during different months. We estimate that your production would vary from a high of 2170 kWh in July, to a low of 1460 kWh in December. For the entire year, we estimate that your 15.76 kW sized system would produce 22240 kWh.
The state of Maryland generally uses Full Retail Rate for net metering. This means that when you produce more electricity than your house uses, the utility will pay you Full Retail Rate for the extra electricity.
