Unbiased guides on solar costs, incentives, and how to calculate whether solar is worth it for your home.
String inverters last 10–15 years and microinverters 20–25 years, but the warranty terms tell the more useful story. We compare manufacturer warranties, replacement costs, and what to budget for during a 25–30 year panel life.
Solar panels produce the most power at midday, but many utilities now charge the most in the early evening. Using EIA price data for 2026, we explain how time-of-use rates change what your solar is worth — and what to do about it.
An average American driver needs roughly 4,000 kWh a year to charge an EV — about 11 kWh a day. Using FHWA driving data and EPA-style consumption figures, we work out the annual energy for light, average, and heavy drivers, and explain why when you charge matters as much as how much.
Cost per watt ($/W) is the single most useful number on a solar quote — but only if you know what goes into it. Using LBNL, SEIA/Wood Mackenzie, and EnergySage benchmarks, we show what a fair residential $/W looks like in 2026 and how to judge a quote in the post-federal-credit era.
Residential electricity prices vary by more than 2x across U.S. states. Using July 2026 EIA data for eight re-checked states, we explain why your local price is the single biggest factor in whether solar pays off.
Do solar panels work in Canadian winters? Learn how much energy snow really costs, why cold weather helps panel efficiency, and practical ways to keep your array producing.
Most homes use roof-mounted solar, but ground-mounted systems offer better angles, cooling, and maintenance access. Compare costs, pros, cons, and which option fits your property.
Solar panel efficiency ratings tell you how much sunlight a panel converts to electricity. Learn what 20%+ efficiency means, how temperature affects output, and whether premium panels are worth it.
The 30% federal residential credit ended with 2025. We walk through what changed, what still helps, and how to judge a solar quote on its gross numbers.

How long does it take for solar panels to pay for themselves in your state, before any incentives? We compare gross installed cost against electricity rates and sun hours for all 50 US states.
We break down the real numbers on gross cost — when solar panels make financial sense, when they don't, and how to calculate your own payback period in under 60 seconds.
