Note: This should only be used as a rough estimate, and may not include any federal, state, or local incentives and/or rebates. Site specific factors may also influence designs that an online calculator can't necessarily determine. A solar installation professional would be able to provide you with a much more accurate estimate.
This calculator also gives rough estimates on how much carbon your current electricity usage contributes to greenhouse gas emissions.
