Verdict

The call

The clearest difference is review sentiment: Lighting Calculations at 60% against My Solar Panel's 43%. Lighting Calculations also leads on rating (4.8 vs 4.6) and update cadence (every 5 weeks vs every 2 months). My Solar Panel's advantage is ratings volume (110 vs 6) and iOS requirement (13.2 vs 15.0). On price, ads, in-app purchases and monetization model there is nothing between them.
