Flatburn Solar Feasibility & Runtime Estimation
This file estimates whether Flatburn will run continuously on solar power in Brazil, using all the hardware and sensor configurations.
1. Instructions
Get your average daily sun hours for your city/month using:
- Global Solar Atlas
- PVWatts Calculator
- Example: Rio de Janeiro in July ≈ 5.5 h/day
2. Flatburn Power Consumption Estimate
- Total current: 211 mA
- Total power: 0.85 W
- Device daily consumption: 0.85 W × 24 h = 20.4 Wh/day
3. Solar Panel and Battery Specs
| Parameter | Value | Units | Notes |
|---|---|---|---|
| Solar panel power | 5.5 | W | |
| Solar panel voltage | 6 | V | |
| Average daily sun hours | 5.5 | hours/day | Brazil average (Rio, July) |
| Solar energy per day | 5.5 × 5.5 = 30.25 | Wh/day | Panel power × sun hours |
| Battery capacity | 10050 × 3.7 / 1000 = 37.19 | Wh | 10050 mAh, 3.7 V Li-Ion |
| Days battery lasts w/o sun | 37.19 / 20.4 = 1.8 | days | Battery Wh / daily use |
4. Results
-
Solar panel provides: ~30 Wh/day
-
Flatburn requires: ~20.4 Wh/day
-
Battery stores: ~37 Wh
-
Daily solar energy is enough for continuous operation with some surplus for battery charging.
-
Battery can run Flatburn for 1.8 days without sun (cloudy/rainy buffer).
5. Tips
- For worst-case (cloudy, winter), use the lowest sun hours for your city/month.
