Purpose and audience

The GRECELL SP-100 is a 100W foldable solar panel built for off-grid power. It suits campers, RV owners and anyone charging a portable power station during outdoor trips or emergencies. Monocrystalline cells deliver up to 100 watts at 20V DC. Buyers needing a fixed rooftop array or higher permanent output should look elsewhere.

Sustained output behaviour

The panel reaches 23.5% cell efficiency and maintains a 20V output voltage under full sun. A built-in smart chip regulates current up to 25A maximum, protecting connected stations from overcharging and overload. Two units can be linked in series or parallel to double the power and shorten charging time. Performance drops when sunlight is low or the panel overheats above 60 °C.

Build, connectors and daily use

The bifold design folds to roughly 25.2 x 10.55 x 3 inches and weighs 5.012 kilograms. Integrated kickstands hold the panel at an angle on flat ground. Reinforced grommets allow tie-down mounting on a tent or RV. The package includes a zippered accessory pouch, an MC4 to Anderson cable and four DC adapters covering 8mm, 5.5×2.1mm, 5.5×2.5mm and 3.5×1.35mm plugs.

Questions about this item

How much heat can the SP-100 panel handle while running all day?

The panel is rated for an upper temperature of 60 °C, so it continues operating in hot conditions.

What connectors must I already have on my power station for the included cables to fit?

The box includes DC 5.5 × 2.1 mm, Anderson, 3.5 × 1.35 mm, 5.5 × 2.5 mm and 7.9 × 0.9 mm (8 mm) adapters.

Can I link this 100 W panel with an older 100 W unit to increase output?

Yes, the SP-100 supports series and parallel connections, letting you combine two panels for up to double the power.
