HoriSol vs Solar Panel Angle Calculator

No hype. Real numbers. HoriSol calculates whether a balcony solar kit actually makes sense at your specific location — using real photo-based shading measurements and conservative assumptions you can actually understand. 6 STEPS TO YOUR YIELD ESTIMATE 1. Location — GPS or address search 2. Panel — power, orientation, tilt, multiple arrays (East/West) 3. Shading — three photos per orientation, real horizon analysis 4. Consumption — household profile with heat pump, EV, hot water 5. Economics — investment cost, electricity price, feed-in tariff 6. Result — annual yield (kWh), payback period, self-consumption rate, CO₂ savings WHY OTHER APPS ARE TOO OPTIMISTIC Vendor calculators use idealized data. HoriSol measures your actual shading from photos, corrects known bias in hourly aggregations, and pulls solar data from the best available source for your location: • PVGIS for Europe and Africa • PVWatts for the USA • NASA POWER as global fallback Results carry a ±10% confidence range — no black box, no magic numbers. NO COMPROMISES • Fully offline — no cloud required, no tracking • No account, no sign-up, no email • All model assumptions openly documented • Country-specific defaults: electricity prices, load profiles, feed-in rates PREMIUM — ONE-TIME, NO SUBSCRIPTION A single purchase unlocks: • 3-page professional PDF report (vs. 1 page free) • Up to 20 saved configurations (vs. 1 free) • Multiple arrays with separate shading analysis • Detailed load profile upload (custom consumption data) WHO IS HORISOL FOR? HoriSol is for renters and homeowners who want an honest answer — not for people already convinced who just want confirmation. If the numbers don't add up, the app will tell you that too.

Portable solar panels aren't roof panels. The "just tilt it to 30°" advice is simply wrong when you're only charging for a few hours at a campsite. SolarPanelAngle finds the angle and direction that harvest the most energy for YOUR hours in the sun — then helps you physically aim the panel until it's right. HOLD YOUR PHONE TO THE PANEL - Lay your iPhone flat against the panel and it reads the real tilt and heading - A two-axis target shows exactly how to adjust: "raise 8°, swing 12° right" - Sound and haptics guide you when you can't see the screen — because your hands are on the panel, not the phone - Turns green the moment it's aimed OPTIMIZED FOR YOUR HOURS, NOT THE WHOLE YEAR - Tell it how long you'll charge — it finds the single best fixed angle for that window - Or track the sun right now for maximum instant output - A daily power curve shows what each angle earns, and compares flat vs best-fixed vs tracking A NUDGE WHEN IT'S TIME TO RE-TILT - Portable setups drift as the sun moves — get reminded when to adjust - "14:00 — set tilt to 55°", scheduled to your own rhythm - A shade warning before a tree or ridge blocks your panel, and a pack-up heads-up before sunset SEE THE SHADE COMING - Scan the horizon around your site and it predicts when the sun drops behind obstacles - "Effective sunlight 4.2 h (10:40–14:50)" — save each campsite and reuse it FULLY OFFLINE — BUILT FOR THE BACKCOUNTRY - The sun is computed on your device from date and location. No internet, ever - Temperature loss is built in, so summer estimates match reality - One-time purchase. No subscription, no ads, no account. Nothing leaves your phone SolarPanelAngle is a planning aid. Estimates assume clear sky; real output varies with clouds, temperature, shade and panel condition. Never stare at the sun or point the camera at it for long.
