Hi Product Hunt! 👋
I'm excited to introduce SolarSizeCalc, a free collection of online solar energy calculators.
I built SolarSizeCalc to make solar planning easier for homeowners and DIY enthusiasts who want to estimate their energy needs before investing in a solar system.
You can explore tools for:
Solar system sizing
Solar panel requirements
Battery storage calculations
Solar energy production
Solar installation cost estimates
The calculators are free to use, with no signup required.
I'd love to hear your feedback. Which solar planning calculator would you find most useful?
