Rated power versus daily energy
Panel watts are measured under test conditions. Actual energy varies with sunlight, orientation, shade, temperature and losses. A rough estimate is rated watts × peak sun hours × a stated loss factor. Try PVWatts for a location-specific estimate.
Electrical compatibility comes first
Compare panel open-circuit voltage (Voc), current and connector with the receiving unit’s input range and limits. A fitting plug alone does not prove compatibility. Follow manufacturer limits and use qualified help for permanent electrical work.
Folding, rigid or flexible
A folding panel can be positioned and stored. A rigid panel may suit permanent mounting. For flexible designs, check ventilation and mounting instructions. Compare size and weight with your space. See our selection guide.
Frequently asked questions
How much energy will a 200 W panel make?
There is no fixed daily figure. Sunlight, orientation, shade, temperature and losses all matter.
Can any panel charge my power station?
No. Check voltage, current, power input and connector against the station’s official specifications.
