Grades compared - turret001/OffGrid GitHub Wiki
Every part comes in grades. Worn and improvised ones get you started; better grades make more, waste less and last longer.
Solar arrays
| Salvaged Solar Array | Solar Array | Monocrystalline Array | |
|---|---|---|---|
| Rated, full sun | 351 W | 574 W | 1161 W |
| Rated, Realistic Mode | 65 W | 142 W | 181 W |
| Modules | 2 | 2 | 3 |
| Cell efficiency | 13.5% | 17.5% | 21.5% |
| Dust builds up | 1.6× | 1× | 0.7× |
| Wears | 1.7× | 1× | 0.5× |
| Heat loss per °C | 0.50% | 0.40% | 0.29% |
| Build | Electrical 2 | Electrical 4, Welding 2 | Electrical 7, Welding 3 |
Roof panels come in the same three grades (Electrical 2; Electrical 4 and Welding 1; Electrical 7 and Welding 2).
Realistic Mode (a sandbox option, see Where the power comes from) uses 1993 cells: three modules to every frame, at 5%, 11% and 14% efficiency. Dust, wear and heat loss stay the same.
Battery racks
| Improvised Battery Crate | Battery Bank | Sealed Battery Cabinet | |
|---|---|---|---|
| Bays (wall version) | 3 (2) | 6 (3) | 8 (4) |
| Stores per battery | 560 Wh | 720 Wh | 920 Wh |
| Round trip | 72% | 86% | 94% |
| Damage floor | 30% | 15% | 8% |
| Left at -10 C | 42% | 55% | 74% |
| Build | Electrical 1, Carpentry 2 | Electrical 3, Welding 3 | Electrical 6, Welding 4 |
Charge controllers
| Charge Controller | MPPT Charge Controller | |
|---|---|---|
| Efficiency | 93% | 96.5% |
| Extra harvest from panels | none | +10% |
