Frequently Asked Questions

Which state is absolutely best for solar in 2025?

California ranks #1 due to high electricity rates ($0.30-$0.40/kWh), excellent sun exposure, and strong net metering. However, with the federal tax credit expiring December 31, 2025, ALL states become significantly less attractive in 2026. Act now regardless of your state. Check your state's specifics.

Can I still go solar if my state isn't in the top 10?

Absolutely. Every state ProsperShield operates in offers positive ROI - even Tier 2 states provide 150-220% ROI over 25 years. The federal tax credit ($5,000-$10,000) expires December 31, 2025, making 2025 the best year regardless of state ranking. Calculate your exact savings.

How much does my state's ranking matter compared to the federal tax credit?

The federal tax credit ($5,000-$10,000) often exceeds total state incentives. Losing it in 2026 makes even top-ranked states significantly worse. A Tier 2 state in 2025 with the federal credit beats a Tier 1 state in 2026 without it. Install by December 31, 2025 to qualify.

Do cloudy states like Washington really make financial sense for solar?

Yes. Germany (cloudier than Seattle) leads the world in solar. Annual sunlight matters more than daily sunshine. Cool temperatures actually increase panel efficiency. ProsperShield installations in Washington achieve 85-90% of promised production. Explore cloudy climate data.

Will state incentives replace the federal tax credit after 2025?

Unlikely. Most states don't have budgets to replace a $5,000-$10,000 federal credit. Some states may introduce new programs, but they won't match federal levels. This makes 2025 the final year for maximum solar savings. Schedule consultation before deadline.

How quickly do state solar incentives change?

State programs can change quarterly. California's NEM 3.0, Massachusetts' SMART program, and state rebate funds often have caps or deadlines. However, the federal tax credit deadline (Dec 31, 2025) is fixed by law. Get current state data from ProsperShield.
