Frequently Asked Questions
How accurate is this solar calculator?
Our calculator provides a ballpark estimate based on national averages. It uses average electricity rates ($0.13/kWh), typical peak sun hours (4.5/day), and average installation costs ($3.00/watt). For a precise quote tailored to your roof, electricity usage, and local incentives, we recommend getting free quotes from local installers through EnergySage.
What is the 30% federal solar tax credit?
The Investment Tax Credit (ITC) allows you to deduct 30% of your solar installation costs from your federal income taxes. For a $20,000 system, that's $6,000 back. The credit is available through 2032, then steps down to 26% in 2033 and 22% in 2034.
What if I rent my home?
Unfortunately, you generally need to own your home to install solar panels. If you rent, check if your landlord would be open to solar — they'd benefit from increased property value. Alternatively, look into community solar programs in your area, which let renters subscribe to a shared solar array.
How long does solar installation take?
The installation itself takes 1–3 days for most homes. However, from signing a contract to having a working system, the full process typically takes 1–3 months due to permits, utility approvals, and installer scheduling.
