Helioscope (by Folsom Labs) is a leading 3D shading and energy modeling tool for solar PV design. If you are looking for a version, here is exactly what you need to know.

Months passed, and Emma's hard work began to pay off. Helioscope started to take shape as a powerful, user-friendly, and highly accurate software for predicting solar flares and CMEs. The software's algorithms were based on the latest research in solar physics, and its interface was intuitive enough for both professionals and amateur astronomers to use.

: Generate "bankable" reports that estimate exactly how many kilowatt-hours a system will produce annually. Financial Analysis

: Professional users can access a 14-day free trial (sometimes cited as 30 days) to test all features, including 3D design and energy yield simulations, with no credit card required.
