Does Geostellar really measure my house, or is it an estimate?

Geostellar gives you data about your property, not a guess based on neighborhood averages. Two houses that stand side-by-side could have radically different solar energy potential, depending on the size and azimuth of the roof, shading, and many other variables. In areas where we have the best possible data, we can measure the sun’s power on every individual square meter of your roof. Certain elements that factor into our solar calculator, like the weather or electricity rates, will be local average estimates because they don’t vary much from house to house. We know you want to make choices based on the specifics of your property and your family’s needs, and Geostellar gives you the power to make a very detailed analysis.
