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

Works good.
Solaria panels were the perfect addition to our home PV system. The sleek design and exceptional performance, along with A1 SolarStore's swift delivery, exceeded our expectations.

The panels are working fine so far. I run an 8kW system, 5kW to the feed-in. The 8 allows quicker start-up. I have panels on two sides: East and West. I try to select what time or days that I need more power. Hot water system runs when I turn it on, not off-peak. A good system, I am quite happy with it so far. Hoping it keeps working top grade for years to come, even with a cold winter and price rises on the way. I still believe the system will keep in front.

Outstanding service! It’s too early to say anything now, but the price was great and I got the modules fast and undamaged. Have to admit, they look really cool
I did the research and compared Solaria 365W to a few competitors. The efficiency was a factor because I want to use my roof space wisely. I also liked that the company manufactures its modules inside the US.
A friend has been using this brand for over five years. From inquiry to completion, the store worked seamlessly.
I think you have done a wonderful job and I appreciate everything. I hope to do lots of business with you in the future.
I finally have my system up and running. I am happy with what I am producing and with the quality of the products. Thanks for all your help
Just wanted to thank all of the co-workers in handling my order. This has been the best customer service ever.
I've been able to do a lot of research in these panels and they seem to be extremely durable and efficient which were the most important qualities to me.
Based on a combination of panel efficiency and cost, Solaria offers a great quality product. From fit and finish to aesthetics, and overall value, I believe this panel meets our needs perfectly.
The panels seem very well built and perform as expected. They are also nice looking and integrated into our home's overall design perfectly.
Solaria solar panels have one of the best warranty out on the market and they look great on our roof. They blend in very nicely.
I have done a lot of research and found out that these panels are probably the best right now. They have been installed for a little over 6 months now and I cannot be happier with how they perform. I also like the way they look a lot.
These panels were of higher capacity than some of the other panels at the same price range. They look good on the roof, and seem to be working well.
We are very pleased with the performance and the appearance of these panels.
Clearly a top-of-the-line panel. The lightweight frame makes installation faster and safer. The 25-year product and linear power performance guarantees say it all for this high-efficiency panel. And they look great.
Thank you for a great customer service. I did not feel rushed or pushed to buy anything when I asked for advice. I got the information I needed, all my questions were answered and I, ultimately, ended up buying these panels based on the recommendations that I have received. So far, I am very happy with my choice.
We've had these panels for over 4 months and they seem to be performing quite well. I am happy with their appearance too. On our black roof they are almost invisible.
I was looking to mount solar panels on front of the house, so appearance mattered a lot to me. Solaria deep black panels look great and perform well. I am happy with the purchase.
I'm impressed by the excellent quality I of my Solaria modules. They also look fantastic on my roof. You get top tier performance for such an affordable price.
We wanted a high quality panels that were backed by a good warranty. Solaria offered worry free warranty and quite competitive pricing for their quality product. The modules perform very well.
These are simply the best panels you can get. They are the most efficient panels I've seen and so much cheaper than the competitors. I am so glad I have found this brand and install these modules.
I've looked at a lot of solar panels trying to find the product that will work for me. And I have to say these panels are beautiful. They look like they made out of a single piece of black silicon. They also are so efficient. I am so happy I took my time and looked at a few brands before finally buying Solaria panels.
I love the way they look and they seem to produce great even with very little sunshine. Very happy with them!
I am very satisfied with the panels as they look great, work efficiently, and were very cost effective.
Great looking, all black, high output panel that also has a great warranty. They work well for me and I would definitely recommend them to anybody.
Best panels we ever had to install
I wanted fewer panels, but with high efficiency. Three months in, they are meeting the original projections. I want to see how they perform over the next 12 months, particularly in the winter.
These are American made panels that are very efficient and look great. Happy with the purchase and proud to support an american manufacturer.
Very efficient panels with an excellent power output. I was able to get fewer panels and still generate an adequate energy to provide my household with enough electricity.
These panels were recommended to us, but unfortunately, due to unforeseen circumstances, we had to return them after purchase. The return policy made it very easy for us, the restocking fee is quite reasonable for a big purchase like this.
This review is for customer service. We had no idea what we were looking for. The young man we talked to was so patient and knowledgeable, he did not push us to buy anything but rather explained what we did not understand. Thank you!
These panels are so beautiful! They made my house look so good.
I know it was a big investment for me, these panels are more expensive than some of the other brands, but I am glad I went with them. They seem very durable and for sure are very efficient.

In the event, the product is only available on East or West coast custom quote will be sent to you before the order is processed. Normally, we are able to deliver solar panels within 7 business days.
What is the difference between low price panels and top price panels?
With top tier solar panels, you pay for the brand name, proprietary new technology, higher energy output, and better warranty support.
What are the dimensions of the panel?
Please refer to the product datasheet on the product page. We have a datasheet for every product we sell.
How long is the warranty on the panel?
In general, manufacturers provide a 25 year-long performance warranty and a 10 year-long equipment guarantee. Some manufacturers offer 12-15 years of warranty. More information is available in our warranty support section.
Which panels do you recommend for RV, marine?
We recommend Panasonic and Mission Solar panels for smaller systems as their high energy output and excellent craftsmanship guarantee years of service.
Can this panel be used with a 12v system?
Any of our panels can be used for a 12v system with a properly selected inverter and charge controller.
Can I pick up this panel from your fulfillment center to save on shipping?
Yes, we can set up a pick up at a local distributor. Please call to discuss options and stock availability.
How do I connect these panels?
To achieve the best system efficiency, panels should be connected in series to create higher voltage.
How many panels do I need?
This number is determined by your average energy needs. Depending on the type of panels and energy consumption, you might need anywhere from 12 to 45 solar panels. Remember, the more panels you install the more energy you will get.Please use our solar calculator to estimate your energy consumption and plan on building a solar system that will exceed your energy needs by 25%.
How do I build a solar system?
Please use our solar calculator to estimate what equipment you need. Choose your panels, microinverters, inverters, and solar batteries if necessary.Please note that we do not offer solar system design or installation.
How do solar panels compare?
Solar panels differ by power output, voltage, connection type, size, efficiency, and weight. Some solar panels might be sold together with microinverters as a set.
Can I build a solar system by myself as a Do It Yourself project?
Yes, it is possible if you understand what solar equipment you need and how to connect it together. However, please be mindful that handling your own electrical work without having proper experience might cause life-threatening injuries. Please contact a certified electrician if you do not possess appropriate electrical skills.
Can I connect and charge my solar panel battery directly with the solar panel?
We do not recommend using the solar panel without the charge controller. Using solar panels without the charge controller might damage the batteries.
Can I drill holes into the aluminum frame for mounting?
We do not recommend drilling any new holes to the aluminum frame of the panel as it could damage the internal circuit and solar cells. (Also, any modification to the panel will void the warranty). We recommend only using the pre-drilled holes for mounting.
Do solar panels require maintenance? Can I wash my solar panel?
Solar panels generally require very little maintenance. We recommend cleaning the solar panel with water, glass cleaner (Windex) and microfiber cloth.

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.
