Summary

ETFE front and A case, one year of cover

The RSP120EF is Renogy's 120 W E.Flex panel with PERC cells, a folding portable sold with a carry case.

Verdict

It suits a buyer who wants a cased 120 W panel for a small power station, and who accepts PERC cells and the shortest warranty in Renogy's portable range.

RedditProduct-line6.0 out of 10

One r/solar owner running Renogy's 200 W N-type E.Flex with a power station reports about 145 W at midday and about 190 W at the best angle, and rates it the best output per dollar of the portable panels they have owned, a later N-type generation of the E.Flex range than this PERC 120 W. The same owner puts its weight at 14 to 17 lb and measured about 45 W from its USB-C port.

GoogleProduct-line6.0 out of 10

OutdoorGearLab, which buys the panels it tests and earns a commission through its Amazon links, measured Renogy's 200 W N-type E.Flex at 177 W over a one-hour test, 88 percent of its rating, and ranked it first of 12 portable panels with an Editors' Choice award; that panel is the later N-type generation of the E.Flex range, not this PERC 120 W. The same review marks it down for its 14.8 lb measured weight, kickstand legs that adjust less easily than rivals' and an IP65 rating below the IP67 and IP68 of other panels tested.

YouTubeBrand-level6.0 out of 10

Both channels found carry a tie to the panels they review. Freedom in a Can, which passes on a 10 percent Renogy code through Renogy's affiliate link, found no delamination on two 100 W flexible panels after 9 months and 9,000 miles. Johnny's Weekends, which earns Amazon commission on the panels it links, found Renogy's 200 W flexible panel performed well but trailed a CIGS panel under shade (2023, about 128,000 views).

Description

The Renogy E.Flex 120W is a folding portable panel built on PERC monocrystalline cells, the older sibling of Renogy's N-type E.Flex range. Renogy's Amazon listing gives it 26.4 x 43.4 x 0.2 in unfolded, 26.4 x 21.7 x 1.0 in folded and 11 lb (4.8 kg). Renogy advertises 22 percent conversion efficiency for the cells; the rated 120 W over the unfolded area works out to 16.2 percent for the whole panel. The front is ETFE film with corner guards, and an adjustable kickstand tilts it toward the sun. Renogy ships it with a carry case and lists solar connectors and charge controllers as sold separately. Renogy's page calls it IP65-rated in one place and IP67 in another. Renogy's Amazon listing gives it a 1-year material and workmanship warranty, and no power-output warranty or temperature coefficient is published.
