The sun belongs to everyone — and Solmeus shows you what your share of it is worth. Engineering-grade precision in your iPhone. Personalised by what you actually have — your surface, your angle, your shadows, your surroundings, your bill. Not by your postcode. Free for everyone, no ads. Point your iPhone at any surface — a roof, a facade, a carport, a plot of land — and in 30 seconds Solmeus measures it, captures the sky and obstacles around it, and shows how much energy solar panels would generate there, how much they would save you each year, and when they would pay back. WHY THIS ISN'T AN ONLINE CALCULATOR Online calculators guess your roof from a satellite photo and use typical consumption. They miss the trees, the obstacles, the shadows that drop half your morning yield. Solmeus measures your actual surface, scans your obstacles, reads your real bill if you give it one. That's the difference between "solar should pay back in about 8 years for homes like yours" and "X kWh and Y years on this exact roof at this exact azimuth with this exact shadow." FREE FOR PERSONAL USE — IN FULL Solmeus is fully free for homeowners and anyone evaluating solar on their own surface — every feature available, no ads, no in-app purchases gating the report, no daily limits, no paywall. The Pro tier exists separately for solar installers and businesses; it changes nothing for personal users. PRECISION YOU CAN STAND BEHIND - AR surface measurement — your iPhone camera (and LiDAR, when available) measures area, tilt and orientation with sub-degree precision - Sky and obstacle scan — records the trees, buildings and obstacles around your site to model shading through the day - Honest physics, hour by hour — for every hour of the year Solmeus computes the real physics of sunlight on your surface: direct, diffuse and reflected radiation, the sun's path, shading from the obstacles you scanned - Two-layer climate data — authoritative satellite climate data combined with Solebo's own honest global climate model, built for Planet Mood: Earth, which also serves as a transparent offline baseline - Personalised by your bill — optionally scan or upload your electricity bill; the estimate then uses your real tariff and consumption - Honest financial model — yearly generation, savings, payback, every assumption visible - Four scenarios — panels, panels + battery, grid export, full self-consumption - Report Quality score 0–100% — every report tells you how confident the estimate is and why - Shareable PDF report THE NAME Solmeus comes from Latin sol meus — "my sun". The sun above you is yours; you have the right to know what it's worth. PRIVACY BY DESIGN No ads. No analytics. No tracking. No third-party SDKs. No user account. Your camera scans, AR measurements and electricity bill content stay on your device. The only thing Solmeus sends off your phone is your approximate location, to a public European climate-data service, only to retrieve solar irradiance for your site. LANGUAGES English · Ελληνικά · Русский · Español · Deutsch · Français · Italiano · Português · 日本語 · ไทย REQUIREMENTS iOS 17.6+. LiDAR-equipped iPhones (iPhone 12 Pro and later) give the most precise measurements but are not required. IMPORTANT Figures shown by Solmeus are indicative estimates based on satellite climate data and the information you provide. Actual results depend on hardware, installation quality, weather, future tariff changes and other factors. Solmeus is a planning tool, not a guarantee.

Verdict
The clearest difference is in-app purchases: Solmeus at none against PV Calculator.'s 1. PV Calculator.'s advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.6). On price, update cadence and ads there is nothing between them.
