Our take on the TSP 100W 12 Volt Solar Panel 2Pack

A two-pack of compact 100W 12V monocrystalline panels built for tight roof space on RVs, vans, cabins and boats. The square 31.8 x 27.5 in shape is about 11% smaller than standard long panels, so two fit where one long module might not. Nine-busbar Grade A+ cells and 100% EL testing are the headline claims, along with 2400Pa wind and 5400Pa snow ratings and IP65 junction boxes. Owners rate it well overall, though a few report output below the rated wattage in real-world sun.

What reviewers say

  • 4.4 / 577 ratings

Buyers rate the panels 4.4 out of 5 and mostly praise the compact square shape and solid build. The main complaint is output that comes in under the rated wattage in less-than-ideal sun.

What people mention
  • Size and fitPraisedOwners like the short square shape because it fits roof areas a long panel cannot.
  • Build qualityPraisedThe aluminum frame and sealed junction box feel durable to buyers.
  • OutputMixedSome owners measure less than the rated 100W in real conditions, while others hit close to it.
  • InstallationPraisedPre-drilled holes make mounting quick, though brackets are bought separately.
  • ValueMixedBuyers note the extras needed to finish an install add to the overall outlay.

About the TSP 100W 12 Volt Solar Panel 2Pack

This is a 100W, 12V monocrystalline solar panel sold as a pack of two. Each panel is a compact, square module, about 11% smaller than traditional long panels, made for limited roof areas and confined spaces. It can be used on RVs, camper vans, motorhomes, cabins, boats, yachts, and off-grid setups.

Each panel uses 9BB 166mm Grade A+ cells with 100% EL testing and up to 23% cell efficiency. The frame is anti-corrosion aluminum alloy. The connectors and junction box are IP65-rated to resist water splashes and rain. The panel withstands 2400Pa wind loads and 5400Pa snow loads.

Pre-drilled holes on the back make installation quick. The panel works directly with HQST Z Brackets and Tilt Mounts, which are not included. It comes with a 5-year product warranty and is rated to retain 80% of its output after 25 years.

Questions and answers

Do I need to buy mounting brackets separately?
Yes. The panels are compatible with HQST Z brackets and tilt mounts, but those are not included. Pre-drilled back holes are there for mounting.
Can I wire the two panels together?
Yes. Wire them in series for a 24V nominal array or in parallel for 12V with higher current. You supply the branch connectors and cable.
Will it work with my existing charge controller?
Match the controller to the array voltage and current. A 12V nominal pair in parallel suits most 12V PWM and MPPT controllers; series wiring needs an MPPT rated for the higher voltage.
How does it handle snow and wind?
It is rated for 5400Pa snow load and 2400Pa wind pressure, which covers typical rooftop conditions when mounted securely.
What warranty comes with it?
A 5-year product warranty, plus an output guarantee of 80% after 25 years.
Is it good for a boat or marine install?
The anti-corrosion aluminum frame and IP65 junction box suit marine use, but mount it clear of spray and check your wiring for corrosion.
