Common questions
How is this different from the Google solar calculator?
Google's Project Sunroof uses roof imagery and local weather patterns to estimate a property's solar potential. This solar roof calculator uses the dimensions and available area you enter. It does not inspect satellite imagery, detect shade or produce a property-specific roof design.
Is this a Tesla Solar Roof calculator?
No. This tool calculates a space allowance for rectangular solar panels using the dimensions you enter. It does not design a solar-tile roof or calculate Tesla Solar Roof pricing. For a product-specific roof assessment, use the official Tesla service; do not treat a panel-area estimate as a solar roof tile quotation.
計算方法
結果を使用する前に
This conservative planning allowance is not a geometric layout. Tilt, row-to-row shading, obstacles, setbacks, roof shape and structural capacity require site-specific checks; an area match does not guarantee the panels fit.
Does enough area mean installation is possible?
No. Roof loading, usable dimensions, shading, access and setbacks can still limit installation.
