Verdict
The clearest difference is rating: My Solar Panel at 4.6 against Xiaoxiang BMS's 3.6. My Solar Panel also leads on iOS requirement (13.2 vs 16.0). Xiaoxiang BMS's advantage is review sentiment (55% vs 33%) and update cadence (every 4 weeks vs every 2 months). 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 My Solar Panel sells 2 in-app purchases, starting at $9.99 per month. Whichever you choose, the download price is not the number that matters.
My Solar Panel holds the better App Store score, 4.6 against 3.6. Both are backed by a comparable volume of ratings — 66 and 108 respectively. Written reviews complicate that: 55% of Xiaoxiang BMS's written reviews are positive against 33% of My Solar Panel'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, My Solar Panel every 2 months. The most recent releases landed on September 23, 2026 and August 16, 2026 respectively.
