Are solar panels worth it for your home?
Estimate savings and payback using your electricity consumption, local solar radiation, and regional daily and seasonal usage patterns. Compare solar with or without a battery.
Regional average profiles are scaled to your consumption; they are not measurements of your household. Results are estimates, not a quote or a guarantee. Methodology and assumptions
When do solar panels pay off?
A lower installation cost, a suitable unshaded roof and electricity use during sunny hours can improve payback. Low daytime use, a costly installation or a short time remaining in the home can make the investment less attractive. Compare local quotes and test higher and lower electricity prices.
Why daily and monthly usage patterns matter
Two homes with the same annual consumption can save different amounts. Daytime use overlaps with solar generation; evening use may need stored energy. Winter heating and summer cooling change the monthly balance. A battery shifts energy between hours, not from summer to winter, and more self-consumption does not always mean better financial returns.
