Question 1

How much do solar panels cost?

Accepted Answer

The average residential solar installation costs $15,000–$25,000 before incentives, or $10,000–$17,000 after the federal solar tax credit (30%). Cost per watt ranges from $2.50–$3.50. A typical 6kW system for a 2,000 sq ft home costs around $18,000 before credits.

Question 2

Do solar panels increase home value?

Accepted Answer

Yes. Studies show solar panels increase home value by an average of 4.1%, or roughly $20,000–$30,000 for a median-priced home. Owned systems add more value than leased systems. Buyers increasingly view solar as a desirable feature.

Question 3

How many solar panels do I need for my house?

Accepted Answer

The average U.S. home needs 20–25 panels (6–8 kW system) to offset 100% of electricity usage. This varies by your electric bill, roof orientation, local sun hours, and panel efficiency. A $150/month electric bill typically requires a 7–8 kW system.

Question 4

Is the solar tax credit still available?

Accepted Answer

Yes. The federal Investment Tax Credit (ITC) provides a 30% tax credit for residential solar installations through 2032. It then steps down to 26% in 2033 and 22% in 2034. State and local incentives may provide additional savings.

Question 5

Should I buy or lease solar panels?

Accepted Answer

Buying (cash or loan) maximizes financial return — you keep the tax credit and own an appreciating home asset. Leasing or PPAs offer $0 upfront but lower total savings, and the lease may complicate home sales. If you can afford to buy, it’s typically the better financial move.
