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.

Sizing Notes

  • Match watts to the controller and battery: a single 100W panel on the Renogy portable pick, 200W pairs on the ECOBOSS and STAR picks, and single 100W panels on the title-only picks.
  • Match efficiency to the roof space: 25.8% on the ECOBOSS pick, 25% on the Renogy portable, STAR and Renogy title-only picks, and 23% on the HQST pick.
  • Match voltage to the controller input: 21.6 volts maximum on the Renogy portable pick, 20.88 volts on the ECOBOSS pick, and 20.4 volts maximum with 17.5 volts output on the STAR pick, with no maximum voltage stated for the title-only picks.
  • Match weather rating to the install: IP67 on the Renogy portable pick, IP68 on the ECOBOSS and STAR picks, IP65 in the HQST title, and no weather rating stated for the Renogy title-only pick.
  • Match warranty to the risk: only the Renogy portable pick states a term, at 3 years for output and material and workmanship, and the other picks state no warranty term.
