Understand Your Solar Numbers

Solar costs

The estimated cost to install solar at your house is $39,042. We calculated this because we think your electricity usage for the year is about 14960 kWh, and a 11.06 kW size solar system on your roof would replace 100% of your usage. We are using an estimated cost of $3.62/W, which we get from Tracking The Sun.

Current electricity costs

The current electricity costs for Eversource Energy East are 17¢/kWh. So, by replacing 100% of your usage, you’ll save $2,610 throughout the year. If the costs of electricity stay the same, then your savings will pay for your solar system in 8.95 years. If the costs of Eversource Energy East electricity rise 3%, then your savings will pay for your solar system in 8.69 years.

Solar production throughout the year

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 1500 kWh in July, to a low of 920 kWh in November. For the entire year, we estimate that your 11.06 kW sized system would produce 14960 kWh.

How We Crunch the Numbers

1
We estimate every home's electricity usage based on data from a number of public and private data sources, including your electricity distributor and the Department of Energy.
2
We overlay key information about where you live, including weather and climate data about your region, and housing data like when your home was built and how big it is.
3
To figure out your home's carbon footprint, we look at how electricity is generated in your state, like whether your electricity is coming more from coal (very carbon-intensive) or wind (carbon-free).

Using this data-driven approach, we have created a machine learning model that can estimate electricity usage and carbon footprint for every home in the US. We then use this information to recommend the best options for you, so you can feel good that WattBuy is recommending something truly personalized.

Our electricity estimations are trusted by our partners at The Department of Energy's National Renewable Energy Laboratory, as well as many of the biggest consumer brands in the world.
