How much energy it adds
A 400 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 | 1,560 Wh/day |
| Texas | 5.0 | 1,500 Wh/day |
| California | 5.5 | 1,650 Wh/day |
| Southeast (GA, SC, NC) | 4.7 | 1,410 Wh/day |
| Mid-Atlantic and Northeast | 4.2 | 1,260 Wh/day |
| Midwest and Great Lakes | 4.2 | 1,260 Wh/day |
| Mountain West | 5.4 | 1,620 Wh/day |
| Pacific Northwest | 3.6 | 1,080 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.
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.
- ?ConnectorMatch the panel's connector to the station's cable or adapter.
- iSpace and anglePanels need open sun and an angle toward it; shade on part of a panel can cut output sharply.
