Solar FAQs

How much does solar cost in 2026?
A typical residential 7 kW system costs $18,000-$28,000 before the 30% federal tax credit. After incentives, net cost is $12,600-$19,600. Battery storage adds $8,000-$15,000 depending on capacity. Final pricing depends on your home, usage, and location.
Is solar worth it in California, Hawaii, and Illinois?
Yes in all three states, for different reasons. California has high rates and good sun (6-9 year payback). Hawaii has the highest rates in the US (4-6 year payback). Illinois has Illinois Shines RECs and federal credits (7-10 year payback).
How long do solar panels last?
Quality solar panels last 25-30+ years with minimal degradation. Most come with 25-year production warranties guaranteeing 80%+ output. Inverters typically last 10-15 years. Batteries last 10-15 years depending on usage cycles.
Will solar work during a power outage?
Grid-tied solar without battery storage shuts off during outages for safety. With a battery backup system, your solar continues charging the battery and powering essential circuits during outages, including PSPS events in California and storms in Hawaii.
What incentives are available for solar?
The 30% federal solar tax credit applies to all three states. California offers SGIP storage rebates and property tax exclusion. Hawaii offers property tax exemptions. Illinois provides Illinois Shines REC payments plus utility smart inverter and storage rebates.
Do I need a battery with my solar system?
In California (NEM 3.0) and Hawaii (Smart Export/CSS), a battery is strongly recommended or required for new interconnections. In Illinois, a battery is optional but provides backup power and maximizes self-consumption under the new 2025 net metering rules.
