Summary

Bends to 240 degrees, warrantied for five years

The RNG-100DB-H is Renogy's 100 W, 12 V frameless flexible panel, 0.1 in thin and 5.3 lb, made to be bonded to curved RV, van and boat roofs.

Verdict

It suits a buyer who needs 100 W glued flat to a curved roof and accepts output covered for 5 years rather than the 25 years of Renogy's rigid panels.

5.5 out of 10

RedditProduct-line6.0 out of 10

Owner reports on Reddit about Renogy's flexible panels are few; one r/SolarDIY owner said flexible Renogy panels trimmed to fit a van roof still worked after about 2 years (January 2025).

GoogleProduct-line3.0 out of 10

Forum owners of Renogy's DB-H flexible line report delamination. On iRV2 an owner's 160 W panel from the same line delaminated and let water in under 4 months after it was glued to an RV roof, and Amazon, not Renogy, replaced it (July 2019). On DIY Solar Forum an owner of eight 160 W panels found one delaminating after almost 5 years and 50,000 miles and opened a warranty ticket (February 2023).

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).

AmazonProduct-line7.0 out of 10

Renogy's 100W-Black/White flexible listing on Amazon US (B07BMNGVV3) reads 4.4 from 967 ratings, 72 percent five-star and 6 percent one-star, but its specification block describes an earlier 48 by 21.5 in, 4 lb generation rather than the current 43.0 by 22.9 in, 5.3 lb panel. Amazon's review summary reports mixed power output, with 16 of 48 tagged reviews negative and one owner seeing 52 W at most in full sun, and mixed durability, 7 of 22 negative.

User reviewsNot scored

The retailer pool is blank: Walmart's listing shows 4.7 from 50 ratings, but 48 of its 49 written reviews are syndicated from renogy.com, and Home Depot's 4.7 from 87 is pooled across five flexible sizes with 38 of the 60 reviews read syndicated, leaving 3 native reviews of this 100 W panel.

Trustpilot

Track record

The BBB rates Renogy A+ and has accredited it since January 2014, with 122 complaints filed in the last three years.
CPSC recall 16-725 (2016) replaced about 1,500 RNG-100DB bendable panels for fire risk, and NHTSA recall 24E-005 (2024) gave about 1,800 RV-maker battery packs a firmware fix.
