Solar for Beginners: The Complete 2026 Guide Before You Buy
New to solar? This beginner guide covers how solar works, what a system costs, net metering, incentives, and the 5 questions to answer before you get your first quote.
Start with your bill, not the panels
Your monthly kWh usage and rate are the two numbers that decide everything. A $250/month bill in a high-rate state justifies solar; a $90 bill in a cheap-power state usually does not. Find your kWh and rate on your latest bill, then use the PVFig ROI calculator as your starting point.
Understand the four moving parts
1) System size (kW) — sized to your usage. 2) Production — depends on your state's sun. 3) Net metering — what your utility pays for exports. 4) Incentives — state credits, rebates, SRECs. Each varies by state, which is why a national "average" answer misleads you.
Get 3–5 quotes and compare apples to apples
Never accept the first quote. Compare $/W price, equipment brands, degradation rate, workmanship warranty, and financing terms side by side. A slightly higher $/W with a 25-year workmanship warranty can beat a cheap quote with a 5-year warranty. See the PVFig financing comparison tool.
FAQ
How does solar work for a homeowner?
Panels on your roof convert sunlight to DC electricity, an inverter changes it to AC, and net metering credits your surplus exports. You keep drawing from the grid at night and pay only for net usage.
How much does a solar system cost in 2026?
Roughly $15,500–$19,500 for a typical 6 kW system before state incentives. The federal residential credit expired Dec 31 2025, so state incentives matter more than ever.
Is solar worth it for me?
Run the PVFig 30-second quiz — it factors your state's rate, sun, net metering, incentives, your roof, and your plans to give a go/no-go verdict.
