100W Portable Solar Panel 23.5% Efficiency

The GRECELL ESP100 is a 100W portable solar panel built with monocrystalline cells and ETFE lamination to deliver 23.5% conversion efficiency. It folds into a briefcase-style design weighing 6.1 pounds and measures 48.62 in by 22.04 in by 0.2 in when unfolded. An IP65 rating protects against water jets and dust. Integrated kickstands and corner grommets allow fast setup on flat ground or mounted to vehicles and tents.

Suits off-grid campers and power-station owners

This panel suits users who need a foldable 100W source to recharge portable power stations through the included MC4 multi-connector kit covering Anderson, DC5521, 8mm, and several DC barrel sizes. It also serves 12V battery charging when paired with an external charge controller. Buyers who require a permanently mounted residential array or a higher single-panel wattage without linking multiple units should consider other options.

23.5% cell efficiency drives output

The 23.5% monocrystalline cell efficiency is the key specification determining how much power the panel harvests per square inch. At STC the panel produces 120W Pmax at 18V Vmp and 5A Imp; NOCT ratings match those voltage and current figures. Two panels can be combined in series or parallel for 200W total output.

Questions about this item

Which portable power station connectors are included in the MC4-to-multi cable kit?

The kit ships with Anderson, DC5521, 8 mm, 5.5×2.5 mm, 5.5×2.1 mm, 3.5×1.35 mm and 7.9×0.9 mm plugs, covering 95 % of power stations on the market.

Can I connect this panel to a 12 V battery without buying extra hardware?

A separate charge controller is required to charge 12 V AGM, lithium or LiFePO4 batteries safely.

How do I confirm the panel is producing its rated output after unfolding it?

Under full sun the panel should show roughly 18 V at 5 A (about 120 W STC); a built-in smart IC chip also protects against over-charge, over-current and short-circuits.
