Ratings & Reviews
Smarter setup, clearer answers.
• Find your home by town or city name. NASA sunshine data loads automatically.
• Your inputs are remembered between sessions.
• Budget is now respected when sizing systems, and over-budget setups are flagged.
• See your projected monthly bill after solar, plus CO₂ equivalents (trees, km not driven).
• New Settings screen: light/dark theme, restore purchase, reset data.
• Saved configurations keep their inputs and can be re-run.
• Comparison highlights the best value per metric. PDF reports now list every assumption.
• Fixes: chart currency outside the US, southern-hemisphere seasons, a crash on very small roofs, and dark-mode readability.
