12. Frequently Asked Questions
1. How much does it cost to install solar panels on a 2,000 sq. ft. house?
The cost ranges from $19,000 to $30,000 without battery storage, and $26,000 to $42,000+ if you include a 10–15 kWh battery. Federal and state incentives can significantly reduce this price.
2. Is a battery necessary for a home solar system?
No, batteries are optional. However, they allow you to store energy for night use, maintain power during outages, and reduce reliance on the grid. A 10 kWh battery typically adds $7,000–$12,000 to the project cost.
3. How long does it take to break even on solar?
The typical payback period is 6–9 years for a system without batteries and 9–13 years with batteries, depending on your energy usage and local electricity rates.
4. Can solar panels power my entire home?
Yes, a well-sized system (6–8 kW) can offset 100% of your average annual electricity needs, especially if paired with good sunlight exposure and energy-efficient appliances.
5. What incentives are available for homeowners?
U.S. homeowners are eligible for a 30% federal tax credit through 2032. Many states and utility companies also offer cash rebates, net metering, and tax exemptions.
6. How long do solar panels last?
Most modern panels last 25–30 years, with warranties often covering 80%+ performance over that span. Inverters and batteries may need replacement after 10–15 years.
7. What if my roof needs repairs?
It’s recommended to repair or replace your roof before installing solar if it's over 15 years old. Doing both together can save on labor and permit costs.
8. Can I still install solar if I live in a cloudy state?
Yes. Solar panels still produce electricity in cloudy weather—just at reduced output. Locations like New York, Oregon, and Michigan still see strong solar ROI with proper system design.
9. Are solar panels worth it in 2025?
Yes, especially with rising electricity prices and extended federal tax credits. Solar adds long-term energy savings and increases home resale value.
10. Will I still get an electric bill?
Usually yes, but it may be very low. If your system covers 100% of your usage and your utility offers net metering, you may only pay basic service fees ($5–$20/month).
