Solar panel installation guide for system sizing, cost estimates, financing options, federal tax credits, installer selection, and ROI calculations.
Evaluate roof orientation, shading, age, and structural integrity. Confirm utility net metering policy in your area.
Calculate system size in kW based on annual kWh usage, offset target (80–100%), and available roof area.
Get quotes from 3+ installers, apply 30% federal ITC, state rebates, and SRECs. Calculate net cost and payback period.
Compare installer warranties, equipment brands, timeline, and financing options (cash, loan, HELOC).

Size system based on usage, roof area, and sun exposure. · Calculate net cost after federal and state incentives.
Calculate current electricity costs to model solar offset savings.
Compare solar loan monthly payments versus utility bill savings. · Calculate annual CO2 offset from solar production.
Track actual versus projected savings post-installation.
Payback depends on electricity rates, sun hours, and incentives — higher rates mean faster payback.
| Region | Avg Payback | Electricity Rate | Sun Hours/Day |
|---|---|---|---|
| California | 6–8 years | $0.25+/kWh | 5.5–6.5 |
| Texas | 8–12 years | $0.12/kWh | 5.0–6.0 |
| Northeast | 7–10 years | $0.20+/kWh | 4.0–5.0 |
| Pacific NW | 12–15 years | $0.11/kWh | 3.5–4.5 |
