Question 1

How much do solar panels cost in 2026?

Accepted Answer

The average residential solar installation costs $15,000-$30,000 before incentives, or $2.50-$3.50 per watt. After the 30% federal tax credit, the net cost is typically $10,500-$21,000. A typical 7 kW system costs about $19,600 before the credit and $13,700 after.

Question 2

What is the federal solar tax credit?

Accepted Answer

The federal Investment Tax Credit (ITC) allows you to deduct 30% of your total solar installation cost from your federal income taxes. This includes panels, inverters, batteries, wiring, labor, and permits. The 30% rate is available through 2032. You must have enough tax liability to claim the full credit (carry forward is allowed).

Question 3

How long do solar panels last?

Accepted Answer

Solar panels typically last 25-30+ years. Most panels come with a 25-year production warranty guaranteeing at least 80-85% of rated output. The panels do not stop working after 25 years - they simply produce slightly less electricity. Inverters last 10-15 years (string) or 25 years (micro) and may need replacement during the panel lifespan.

Question 4

How long does it take for solar panels to pay for themselves?

Accepted Answer

The average solar payback period in the US is 7-12 years, depending on your location, electricity rates, system size, and incentives. States with high electricity rates (CA, NY, MA, CT) and good incentives see payback in 5-8 years. After payback, solar electricity is essentially free for the remaining 15-20+ years of panel life.

Question 5

Do solar panels work on cloudy days?

Accepted Answer

Yes, solar panels produce electricity on cloudy days, but at reduced output (10-25% of full capacity). Panels respond to light, not heat - so even diffused sunlight generates some power. Cities like Seattle and Portland still have viable solar economics despite cloudy weather because panel efficiency and electricity rates make up for fewer sun hours.

Question 6

Will solar panels increase my home value?

Accepted Answer

Yes. Studies by Zillow and Lawrence Berkeley National Laboratory show that solar panels increase home values by an average of 4.1% ($15,000-$25,000 for a median-price home). Owned systems add more value than leased systems. Buyers in high-electricity-rate states value solar installations more.
