How much energy it adds
A 220 W panel produces its rated power only in ideal conditions. Heat, sun angle and cable losses reduce real output; we assume 75% of rating.
| Region | Peak sun hours (approx.) | Estimated energy |
|---|---|---|
| Florida and the Gulf Coast | 5.2 | 858 Wh/day |
| Texas | 5.0 | 825 Wh/day |
| California | 5.5 | 908 Wh/day |
| Southeast (GA, SC, NC) | 4.7 | 776 Wh/day |
| Mid-Atlantic and Northeast | 4.2 | 693 Wh/day |
| Midwest and Great Lakes | 4.2 | 693 Wh/day |
| Mountain West | 5.4 | 891 Wh/day |
| Pacific Northwest | 3.6 | 594 Wh/day |
Pairing it with a power station
A power station accepts solar input only within its own voltage and current limits. Compare this panel's figures with the station's stated solar input before connecting anything.
- Voc 23.6 V
- Vmp 20 V
- Isc 12.1 A
- Imp 11 A
Use the solar recharge calculator to see how many sunny days a station needs.
Fit check before you buy
Checks to make against the power station you plan to charge.
- ✓Station solar input limitsVoltage, current and watt limits of the station's solar port.
- ?ConnectorUnmatched durability with IP68 protection & ETFE coating.
- iSpace and anglePanels need open sun and an angle toward it; shade on part of a panel can cut output sharply.
