I got incredibly frustrated by how hard it was to just answer a simple question: "Will solar panels actually work on this roof, or will the neighbor's trees block the sun?" Usually, you have to hire a specialist using expensive desktop software ($2k-$10k/year) and wait days for a static PDF report. So, I built a frictionless, browser-based alternative. Usually, you have to hire a specialist using expensive desktop software ($2k-$10k/year) and wait days for a static PDF report. So, I built a frictionless, browser-based alternative. Here is what you can do with it (for free): Instant 3D Models: Type any address and get a 3D city model in seconds—no downloads or plugins required. Real-time Shadows: Use the time slider to scrub through any day of the year and watch exactly how shadows sweep across the buildings. Virtual Panel Placement: Click to place solar panels directly on the 3D roof. Trusted Data: It calculates your estimated annual energy production using the European Commission's PVGIS satellite database. There's a completely free forever tier, so jump in, drop an address, and let me know what you think! I'll be hanging out in the comments all day to answer questions.
