Renogy vs Rich Solar 100W Panel
The two most common budget-to-mid 100W rigid monocrystalline panels in RV builds. Electrically near-identical — the decision comes down to price, dimensions and which ecosystem you're buying into.
Renogy 100W 12V Monocrystalline Rigid Solar Panel
| Rated power | 100 W (STC) |
| Open-circuit voltage (Voc) | 24.3 V |
| Max-power voltage (Vmp) | 20.4 V |
| Short-circuit current (Isc) | 5.21 A |
| Max-power current (Imp) | 4.91 A |
| Type | rigid |
| Dimensions | 42.2 × 19.6 × 1.38 in |
Rich Solar MEGA 100W 12V Monocrystalline Solar Panel
| Rated power | 100 W (STC) |
| Open-circuit voltage (Voc) | 24.3 V |
| Max-power voltage (Vmp) | 20.4 V |
| Short-circuit current (Isc) | 5.21 A |
| Max-power current (Imp) | 4.91 A |
| Type | rigid |
| Dimensions | 41.8 × 20.9 × 1.18 in |
Which should you buy?
Spec-for-spec these are a wash: same ~100W, similar Voc/Vmp, both rigid mono. Buy on price and physical fit for your roof. Renogy wins on accessory ecosystem and support footprint; Rich Solar is often a few dollars cheaper and comes with a slightly longer panel warranty. If you're already buying a Renogy controller/DC-DC, matching panels keeps one support contact.
