PV Care vs HoriSol

An automatic system that allows you to meet all connection conditions.

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.
