Eco-worthy 100w vs renogy 100w solar panel is a comparison with a catch: the data holds a Renogy 100W portable panel and an ECO-WORTHY connector kit, but no ECO-WORTHY 100W panel, so the sides are a panel against the connectors that join panels. The short answer: the Renogy REGO 100W is the only panel here, a foldable 100W unit at 25% efficiency, while the ECO-WORTHY kit is the 2-pair Y-branch set that links panels in parallel. Pick the Renogy if the job needs a panel; pick the ECO-WORTHY kit if the job needs to join panels that are already on the roof.

Eco-worthy 100w vs renogy 100w solar panel: side by side
| Panel | Solar Score | Type | Figures | Protection | Size/Weight | Warranty |
|---|---|---|---|---|---|---|
| RENOGY REGO 100W Portable | 9.7/10 | Portable solar panel | 100W, 25% efficiency | IP67, ETFE coating | 8.86 lb, folds to 24.64 x 20.62 in | 3-year + 12-year 80% output |
| ECO-WORTHY Y Branch Kit | 9.3/10 | Y-branch connector kit | 30A, DC 1000V | IP68, UL94-V0 | 13.0 x 6.4 x 0.8 in | Not stated |
We copied each rating from the seller’s listing as the brand states it; data date 14 November 2026.
Power and efficiency
Power is where the comparison breaks down, because only the Renogy listing states panel figures. The Renogy REGO 100W is a 100W panel at 25% efficiency from 16BB cell technology, against 22.5% for standard 9BB panels, and it generates up to 320 Wh daily depending on sunlight. The ECO-WORTHY listing states no watts and no efficiency, since it is a connector kit rated 30A and DC 1000V, made to carry power between panels rather than make it. Calling the ECO-WORTHY side better or worse on power would need a panel figure it does not state, so the power question is answered by the Renogy panel alone.
The same gap runs through the rest of the panel figures. The Renogy panel suits 12V battery systems with a compatible solar charge controller, which is not included, and it has MC4 output cables only, with the Renogy 4-in-1 adapter cable sold separately. The ECO-WORTHY kit fits 10-14 AWG solar cables and connects 3 solar panels in parallel, so it belongs on the wiring side of a system, not on the roof as a panel.
Weight and size
The Renogy panel is built to move. It weighs 8.86 pounds and folds down to 24.64 by 20.62 inches, so it packs away for transport and suits camping, RV trips and emergency backup. The ECO-WORTHY kit measures 13.0 by 6.4 by 0.8 inches and states no weight, since it is a set of connectors and cables rather than a panel. A foldable panel and a connector kit do not share a size class, so the size question is really a portability question, and the Renogy panel is the portable piece here.
Protection and weather
Each listing states weather protection, but for different parts. The Renogy panel carries IP67 protection with a hail-resistant ETFE coating and an aluminum backsheet for heat dissipation, and its parallel wiring keeps output steady when sections are shaded. The ECO-WORTHY kit carries IP68 protection with a UL94-V0 flame retardant mark, withstanding -49°F to 194°F, and its buckles lock the connection in place. The Renogy protection covers a panel in sun, snow and storms, while the ECO-WORTHY protection covers the joints between panels in the same weather.
What the listings leave unclear
The main gap is the missing ECO-WORTHY panel. The ECO-WORTHY listing is a 2-pair Y-branch connector kit, so this comparison cannot rank two 100W panels against each other, and any panel-to-panel verdict would need a listing that is not in the data. The Renogy listing leaves its own gaps: the 4-in-1 adapter cable is sold separately, and the charge controller for a 12V battery system is not included. The ECO-WORTHY kit states no warranty term, while the Renogy panel states a 3-year term on materials and workmanship plus a 12-year term covering at least 80% of the rated output.

Detailed Review
Renogy lists the REGO 100W as a foldable portable panel with 25% efficiency from 16BB cell technology, against 22.5% for standard 9BB panels. It weighs 8.86 pounds and folds to 24.64 by 20.62 inches, and it generates up to 320 Wh daily depending on sunlight. The panel carries IP67 protection with a hail-resistant ETFE coating and an aluminum backsheet, and its parallel wiring keeps output steady when sections are shaded. It has MC4 output cables only, and the Renogy 4-in-1 adapter cable is sold separately. A 3-year warranty on materials and workmanship is stated, plus a 12-year warranty covering at least 80% of the rated output.
Who it's for: campers, RV owners and anyone who needs a light 100W panel that folds away. Who should skip it: buyers who want a fixed roof panel, or a kit with a charge controller included.
Its Solar Score of 9.7/10 comes from performance 32/35, build 22/25, value 20/25, safety 7/10 and warranty 4/5: 85 of 100 points, placed on our 9.2 to 9.8 scale.

Safety and Warranty
What this listing states. IP67 protection and hail-resistant ETFE coating, with an aluminum backsheet for heat dissipation, so safety scores 7 of 10. 3-year commitment on materials and workmanship, plus a 12-year warranty covering at least 80% of the rated output is stated. It does not say everything a buyer needs, such as who pays return shipping, so warranty scores 4 of 5. See How We Pick.
Panels make voltage in daylight. Keep connectors covered until you connect them, check the panel's stated open circuit voltage and current against your controller or power station input limits, and use cables rated for the current. Roof and permanent mounts belong to a qualified installer.

ECO-WORTHY Y Branch Kit
A 2-pair Y-branch connector kit rated 30A and DC 1000V, made to join 3 solar panels in parallel with IP68 protection.
Pros
- Joins 3 solar panels in parallel with 2 pairs of Y-branch connectors
- Rated 30A and DC 1000V, with 10-14 AWG cable compatibility
- IP68 protection with UL94-V0 flame retardant, from -49°F to 194°F
- Plug and play with buckles that lock in place
Cons
- Not a solar panel: it generates no power on its own
- No warranty term is stated
- Parallel connection only, so series wiring needs different connectors
- 2 pairs only, so a larger array needs more kits
Detailed Review
ECO-WORTHY lists a 2-pair Y-branch connector kit rated 30A and DC 1000V, made to connect 3 solar panels in parallel. It fits 14-10 AWG solar cables and carries IP68 protection with a UL94-V0 flame retardant mark, withstanding -49°F to 194°F. The connectors lock in place with built-in buckles and unlock by pressing the sides. This kit is a connector set, not a solar panel: it carries power between panels and has no wattage, efficiency or output of its own.
Who it's for: owners joining 3 panels in parallel who need a connector set for harsh weather. Who should skip it: anyone shopping for a 100W panel itself, since this kit generates no power.
Its Solar Score of 9.3/10 comes from performance 18/35, build 20/25, value 19/25, safety 7/10 and warranty 0/5: 64 of 100 points, placed on our 9.2 to 9.8 scale.

Where the points went
The Solar Score weighs performance, build, value, safety and warranty. For solar panels, safety covers the IP code, the ETFE coating and the parallel wiring on the Renogy panel, and the IP68 code and UL94-V0 flame retardant mark on the ECO-WORTHY kit. The Renogy panel scores higher on performance and warranty for its 25% efficiency and its 3-year plus 12-year terms, while the ECO-WORTHY kit scores lower on performance because it is a connector set, not a panel. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| RENOGY REGO 100W Portable | 9.7 | 32 | 22 | 20 | 7 | 4 |
| ECO-WORTHY Y Branch Kit | 9.3 | 18 | 20 | 19 | 7 | 0 |
We place weighted points on a scale whose ends are 9.2 and 9.8. Because the mapping is straight, a unit with more points never shows less.
Eco-worthy 100w vs renogy 100w solar panel: which should you choose?
Choose the Renogy REGO 100W if the job needs a 100W panel that folds away, weighs 8.86 pounds, and runs a 12V battery system with a charge controller. Compare more portable options in the portable solar panels section.
Choose the ECO-WORTHY Y-branch kit if the job needs to join 3 solar panels in parallel, with connectors rated 30A and DC 1000V for 10-14 AWG cables. See the mounts, cables and connectors section for the rest of the wiring.
Whichever side fits the job, add a charge controller before wiring a panel to a battery; the best solar panel kit for RV guide lines up kits that include one.
| If you need | Look at |
