Question 1

How does a solar panel ROI calculator work?

Accepted Answer

A solar panel ROI calculator estimates the financial return on your solar investment by comparing the cost of the solar system (after tax credits and incentives) against the electricity savings over the system's lifetime. It factors in your current electric bill, electricity rates, annual rate increases, and available tax credits to determine your payback period and total savings.

Question 2

What is the 30% federal tax credit for solar?

Accepted Answer

The Federal Investment Tax Credit (ITC) allows you to deduct 30% of the cost of installing a solar energy system from your federal taxes. This applies to both residential and commercial systems installed between 2022-2032. The credit percentage will gradually decrease in subsequent years.

Question 3

How long do solar panels last and do they maintain efficiency?

Accepted Answer

Most solar panels come with 25-30 year warranties and typically maintain 80-90% of their original efficiency after 25 years. Solar panels degrade at about 0.5-1% per year, meaning they'll still produce electricity effectively for decades. Many panels continue producing power well beyond their warranty period.
