How we scored them
The Solar Score weighs performance, build, value, safety and warranty. For a solar panel, safety means certifications, weather ratings and stated protections the listing actually states; a panel that states none scores zero on that line, whatever its watts. Among the picks, only the Renogy portable panel states a warranty term, at 3 years. How we pick explains the weights.
| Product | Solar Score | Perf. /35 | Build /25 | Value /25 | Safety /10 | Warranty /5 |
|---|---|---|---|---|---|---|
| Renogy 100W Portable Panel | 9.7 | 30 | 21 | 21 | 7 | 4 |
| ECOBOSS 200W Panel Pair | 9.7 | 32 | 22 | 21 | 9 | 0 |
| STAR 200W Frameless Pair | 9.6 | 29 | 20 | 20 | 7 | 0 |
Scores run from 9.2 to 9.8: each product’s point total is placed on that range, so more points always means a higher score.
How to choose the best rigid solar panel under 150
Start with watts and panel count
Watts decide how much power the set can make, and panel count decides how that power is split. The Renogy portable pick is a single 100W panel, while the ECOBOSS and STAR picks are 200W sets made of 2 panels at 100W each. The two title-only picks are each a single 100W panel, with the HQST pick also stating 12V in its title. A pair suits a larger roof or a balanced 12V setup, while a single panel suits a smaller roof or a portable kit.
Match efficiency and voltage to the controller
Efficiency says how much of the sunlight becomes power, and voltage says what the controller must accept. The ECOBOSS pick states up to 25.8% efficiency with a maximum voltage of 20.88 volts and an output voltage of 12 volts, the Renogy portable pick states 25% efficiency with a maximum voltage of 21.6 volts, and the STAR pick states 25% efficiency with a maximum voltage of 20.4 volts and an output voltage of 17.5 volts. The HQST title states 23% efficiency and 12V, with no maximum voltage stated, and the Renogy title-only pick states 25% efficiency with no voltage stated. Match the maximum voltage to the controller input before buying, and see our roof mount vs wall mount solar panel guide for mounting choices.
| Panel | Power | Efficiency | Maximum voltage |
|---|---|---|---|
| Renogy 100W Portable Panel | 100W | 25% | 21.6 volts |
| ECOBOSS 200W Panel Pair | 200W, 2 x 100W | 25.8% | 20.88 volts |
| STAR 200W Frameless Pair | 200W, 2 x 100W | 25% | 20.4 volts |
| HQST 100W 12V Panel | 100W | 23% | Not stated |
| Renogy 100W N-Type Panel | 100W | 25% | Not stated |
Check weather rating, size and warranty
Weather rating says how the panel handles rain and outdoor use. The Renogy portable pick states IP67 with a hail-resistant ETFE coating and operation from -40°F to 185°F, the ECOBOSS and STAR picks state IP68, and the HQST title states IP65, while the Renogy title-only pick states no weather rating. On size, the Renogy portable pick folds to 20.6 x 24.6 x 1.6 inches, the ECOBOSS pick is stated at 23 x 1.18 x 35.8 inches, and the STAR pick at 38.2 x 22.7 x 1.2 inches, while the title-only picks state no size. On warranty, only the Renogy portable pick states a term, at 3 years. For a portable option beyond this group, see our solar panel for backpacking under 60.
