We have 2 x Solaria 400w panels on our monohull sailboat, fastened atop an aft solar arch that doubles as a dinghy davit system. Each panel feeds to their own Victron 100/50 controller for redundancy. We bought these over 2 years ago at ~$400 apiece and would absolutely replace with the same if need be as they work like a charm and look fantastic in all black unlike the doubly priced Renegy panels marketed as “marine” that most cruisers use. The allowance of charging even when partially shaded due to Solaria’s wiring setup also makes them ideal for boats where boom shading is an ever-present challenge. The original set we ordered were damaged in transit and replaced immediately by a1 at no extra charge to us, so shoutout to a1 for excellent customer support as well. My only regret is that we don’t have any storage space aboard to keep more of these panels as backups should the need ever arise!
Solaria panels offer great value for money. Their lightweight design and A1 SolarStore's efficient delivery make them a reliable choice. Opted for Trina due to their efficiency, and the decision paid off

About product

PowerX-3900R-4T is a model that uses a number of technologies to bring durability and performance to the next level. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight.

To further boost the performance, Solaria employs half-cut cell technology. This grants PowerX-390R-4T lower resistive losses and better shade tolerance. Given its size and weight, PowerX-390R-4T efficiency of 20% is quite impressive. And while conventional panels use only one side to absorb photons, bifacial modules employ both sides at the same time. Thanks to the technology, this model can be up to 30% more efficient. Cell surface, back foil and frame are completely black, giving the model unrivaled aesthetics. Solaria provides a 30-year product warranty. Stable power output is also guaranteed — performance warranty will protect you during 30 years.

High productivity thanks to the most recent developments

This Solaria panel produces 390 W of power at 20 percent efficiency. High levels of energy output are reached by utilizing the most recent innovations in the solar sector. A more efficient panel produces more per square foot and pays for itself sooner.

Improved performance at hot temperatures

A high temperature coefficient translates to more energy as the temperature rises. Every 1.8°F increase over 77°F reduces the efficiency of your panel by just -0.36%.

Quality and reliability

PowerX-390R-4T receives multiple quality checks throughout the manufacturing process and is subject to stringent quality and reliability testing. The manufacturing facilities are highly automated, eliminating the risk of human error. Solaria is dedicated to quality, safety and reliability to ensure you get the very best.

Reliability and degradation resistance

Slow degradation over the next 30 years is guaranteed by Solaria. The performance will decrease no more than 2% during the first year and 0.25% annually thereafter. Your modules will retain at least 84.37% of original performance after the 30 years are over. This 390 W Solaria solar panel also comes with a generous 30-year product warranty.

A panel that can handle hail, wind and snow

The 1.4" frame built of anodized aluminum and a layer of protective tempered glass make this module weather-resistant. The front side of the modules can withstand a 5400 Pa load, whereas the back side can withstand a 2400 Pa load.

Outstanding all-black design

The panel has a sleek, all-black style that complements any roof beautifully. Solaria uses unique treatment and selection procedures to guarantee optimum cell color. The cells are connected by thinner wires, and from a distance, the surface of the modules seems seamless and smooth.
