What they say
Renogy 100W Bifacial Panel
- Reddit owners mostly report Renogy's rigid panels holding up: an r/OffGrid owner has run several for more than a decade with none failed, and an r/vandwellers thread on the brand sums it up as panels fine, other gear less so.
- An r/VanLife owner's RSP200D lost half its voltage after about 18 months, and Renogy shipped a replacement in two weeks under the 5-year warranty; that poster is quoted on Renogy's own ShadowFlux page.
- An r/SolarDIY buyer of the 200 W suitcase reported a defective charge controller, two wrong replacement parts and dozens of emails before a 20 percent refund (2025).
ECO-WORTHY 100W Bifacial Panel
- Reddit owners mostly report Eco-Worthy batteries holding their rated capacity and are less sure of its electronics.
- In an r/SolarDIY thread owners said their 100 Ah batteries tested to capacity and that two 12 V 260 Ah batteries in series stayed balanced for a year (February 2024), a UK owner measured nearly 102 Ah from a 12.8 V 100 Ah battery after a year on standby against 104.3 Ah new (June 2025), and in a Renogy-or-Eco-Worthy thread an owner called its batteries and panels fine and its charge controllers and inverters hit and miss (February 2026).

Renogy 100W Bifacial Panel

- On DIY Solar Forum, a 2022 thread opens with an owner whose Renogy gear still works after a decade, while a thread titled 'I only get 85W out of my Two Renogy 100W panels' reports one panel as low as 40 percent of rating and four averaging 54 percent.
ECO-WORTHY 100W Bifacial Panel
- On DIY Solar Forum, an owner running two Eco-Worthy 5000 W inverters in split phase reported them working fine after a year (January 2025), while a buyer of twelve 410 W panels found 7 underperforming and waited about 40 days for replacements (August 2025), and an owner of five 12 V 280 Ah batteries reported 3 faulty from the start (August 2025).
- The Solar Lab, which carries an Eco-Worthy affiliate link and a discount code, found the 48 V server-rack battery handled surges beyond its rating but failed its low-temperature cut-off test, and its calls to Eco-Worthy support went to voicemail (2025).
