Simple and accurate determination of the optimal PV tilt angle. Make your PV System generates maximum electricity for your desired location. The wrong position of your PV System can cause losses in electricity generation and your project feasibility may be a question. With this App you will obtain: - Solar Data charts (elevation, azimuth, sunrise, sunset time, noon time, sunlight duration, etc.) - Tilt vs azimuth optimization (find the ideal tilt angle for any chosen azimuth) - Optimal Tilt angle for any desired location on the map - Optimal orientation - Optimal monthly tilt angle - Optimal daily tilt angle - Optimal hourly tilt angle - On-site inclinometer for measuring angles The tilt angle of the panels is one of the most important parameters for your PV system. It is the angle at which the photovoltaic panels are set to face the sun relative to a horizontal position. The panels must have appropriate tilt angle, set for gaining maximum possible electricity from your PV system for your location. PV Solar Tilt is using optimization model for obtaining the most appropriate tilt angle of your panels in order to gain maximum electricity generation from your system. The model is based on sophisticated simulations for maximizing energy yield for a given location. If you need any assistance or clarification, please let us know at support@pvsolcast.com.

Verdict
The clearest difference is rating: PV Solar Tilt at 4.4 against Xiaoxiang BMS's 3.6. PV Solar Tilt also leads on iOS requirement (13.0 vs 16.0). Xiaoxiang BMS's advantage is update cadence (every 4 weeks vs every 4 months) and review sentiment (55% vs 33%). On price, ratings volume, ads and in-app purchases there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
Both are free to download. Xiaoxiang BMS sells 1 one-off in-app purchase and PV Solar Tilt sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
PV Solar Tilt holds the better App Store score, 4.4 against 3.6. Both are backed by a comparable volume of ratings — 66 and 157 respectively. Written reviews complicate that: 55% of Xiaoxiang BMS's written reviews are positive against 33% of PV Solar Tilt's, so the app with the better star average is not the one people write more warmly about.
Xiaoxiang BMS ships an update every 4 weeks, PV Solar Tilt every 4 months. The most recent releases landed on September 23, 2026 and September 16, 2026 respectively.
