Real impressed how cool they run in desert heat, voltage barely drops
southern humidity no delam issues after a year so far so good.
coastal install zero corrosion after salt-spray season thumbs up.
love that n-type tech, lost almost no power this hot May.
thank you very much!
I had a fantastic experience with solar panels. They power my home well, and I feel good about using less energy and saving money. The customer support was excellent and ensured I was happy with everything.
So far so good, works well even on cloudy days!
installed those, working ok so far
My experience with solar panels has been excellent. The installation was smooth, and the panels are very efficient. I feel good about reducing my carbon footprint and saving money.
pretty good didn’t break the bank, 4.5 if that were a thing
very good prices! better than what most around offer. nice customer service and pickup instructions were clear and helpful. i'll be coming back!
Your Melanie is such a sweetheart!
Black glass gets warm in Texas sun yet voltage drop small nice engineering.
I had a hard time choosing the right solar panels. the customer service was excellent, offering clear advice and detailed explanations about each option. they guided me step-by-step, ensuring I made an informed decision. I’m very satisfied with their help and the panels I chose.
Survived -30 °F snap freeze in Minnesota so yeah they’re tough
Snow load rating proved real survived first blizzard no flexing.
Love the glass-glass build—zero micro-cracks so far and winter reflection added a sweet bonus.
Your Melanie is such a sweetheart!
The panels look fantastic on our roof and are performing even better than expected
bifacial boost is real seeing extra juice off my white metal roof
a bit late on delivery everything else is good
love the all-black aesthetic
Half-cut cells really do help shade lost a tree limb last week barely saw a dip
looks stealthy on charcoal shingles, output steady even in Texas heat
Getting 21 % efficiency right on spec Solid hardware.
My experience with solar panels has been excellent. The installation was smooth, and the panels are very efficient. I feel good about reducing my carbon footprint and saving money.
Delivery took quite a bit — turned out it was fedex fault. well, panels aren’t anything special. the design seems kinda average to me. They work fine though. I have a few trees around the house but the shade from them doesn’t seem to make a huge impact on an array so that’s good.
Pays for itself quicker than I thought.
Performs better than my old 370s by a mile good choice.
there was an error when I made a purchase - a bug as it turned out. we sorted it out. the panels arrived safely. so far so good!
for this money it’s a great product. I like the design and it was quite easy to install. I’ve been monitoring the system and for the past few here in Oregon it was quite cloudy, but the panels were barely affected by it. Overall, it’s a good model, imo
I was very satisfied with my experience at a1solarstore. A star is off for being a bit late on the delivery
Solid build, framed glass feels premium. Survived first hailstorm no sweat
very good prices! better than what most around offer. nice customer service and pickup instructions were clear and helpful. i'll be coming back!
Going solar was a smart decision. The panels work as promised, and I feel good about using clean energy. The customer suport was outstanding, always ready to help. Highly recomend these panels.
I'm pleased with my solar panels. They save me money and work efficiently. The customer service was very suportive and helped me understand the benefits. It's a worthwhile investment.
Thanks for nice service!
So how is my experience with Trina panels? Boring :)) Haven't had any trouble for 6 months already, since i installed them. hope it stays this way
I was completely lost when it came to selecting solar panels. there were so many options and I didn't know which one to choose. your staff was very helpful and provided great advice. they explained everything clearly and helped me decide on the best panels for my needs. the panels are now installed and working perfectly. i'm very happy with my choice and will definitely come back for more.
thnx for the fast delivery and great service! We’ve just finished the installation last week. Panels work fine and id say that for this price they are quite good.
Maybe not the best choice for your roof as i found out a bit too late but great for a yard installation
Shade hits in the morning but the half-cut cells keep output decent, pleased overall
I had a hard time choosing the right solar panels. the customer service was excellent, offering clear advice and detailed explanations about each option. they guided me step-by-step, ensuring I made an informed decision. I’m very satisfied with their help and the panels I chose.
these panels are decent for the price. they do the job without any major issues and are providing a consistent energy output. i'm pleased with the performance so far, but wish they were a bit more efficient.
Put six on my barn roof last summer—still cranking strong even after dusty harvest season.
The panels are used to power my cabin and save me some money. The customer service was helpful and friendly, resolving any issues quickly. Despite a few initial complications, I'm satisfied with my choice.
A1 offered pickup option, which was very convenient for me. The panels were easy to install. Great product, great service!
Delivery was fast and panels were packaged well. Highly recommend
They were picked out by the installer on our behalf. To be honest, I can't say if they are good or bad, time will tell. But A1Solar were pleasant to deal with and very responsive. Panels arrived very well packaged and safe.
I couldn’t decide which solar panels to buy, feeling lost among all the options. the supportive staff made all the difference. they explained the pros and cons of each type and helped me figure out what would work best for my situation. their guidance was invaluable and led me to the perfect choice.
Sleek look and strong output My bill shrank fast
I got solar panels to power my home and they work great. The customer suport was excellent and very helpful. I'm really happy with my decision.
The best price compared to other solar stores
Put in a full pallet on my barn roof—output’s right on spec and the bifacial bump is real. Easy win.
These panels provide good power. i'm happy with them and how they perform. the service team was very supportive and provided clear, easy-to-follow instructions. their help made the setup process stress-free.
No problems. Thanks
One of the panels was broken during shipping, but A1 sent a replacement right away
installed those, working ok so far
i was sceptical at first given the fact that trina is a chinese company and all. but i gotta say that they make damn good panels. Like, I haven't found anything to complain about yet and they don’t even cost that much comparatively.
Great prices. really helpful staff. the pickup option is nice and it's not something that i saw too often in other shops.
i bought these solar panels for my rv trips. they give me the power i need while on the road. the customer service was amazing. they made the whole process easy and stress-free.
5 star for the design and efficiency
I liked the service and the panels are great
We’re reducing our carbon footprint
The solar panels have proven to be reliable and are performing as expected. The installation process was straightforward, and the panels have been meeting our energy needs without any issues. We're pleased with how well they’ve worked so far.
Never saw the prices like this EVER. ANYWHERE.

Put sixteen of these on my barn roof. Power numbers match the spec sheet and they look stealthy black. Zero regrets.
Great deal on a very good Trina solar panel! Getting good output from these panels.
a bit late on delivery everything else is good
i recommend these panels
The panels look fantastic on our roof and are performing even better than expected
the pickup option is what really sets you apart from the competition in my opinion. thanks for your service.
a bit late on delivery everything else is good
5 star for the design and efficiency
thank you very much!
We experienced a severe storm in our area, and our panels held up perfectly. They're built to last
Deciding on the right solar panels was really challenging for me. i was unsure about which type to choose and felt quite confused. your team provided clear guidance and took the time to explain the differences between the panels.
good panels for home. nice design
great service, keep it up
i recommend these panels
Amazing service! I have been looking for a reasonable solar kit off and on for years. After coming across A1 Solar store I had a few questions. Guys answered my first few random questions in detail. From the first response I felt like I was respected and valued as a customer.
The panels are used for my vacation home and work well, saving me money. The customer service was great and very helpful with all my inquiries. There were a few minor issues, but they were resolved quickly by the support team.
5 star for the design and efficiency
Great deal for Trina modules!
The exterior might not be the most important part in a solar panel, but given a choice I would stick with panels that look good. These are both high quality and good looking
Your Melanie is such a sweetheart!
We went with them instead of our original plan, and we couldn't be happier with our decision. Mostly we paid attention to the reviews, and Trina has the most positive real reviews in our opinion
Going solar was a smart decision. The panels work as promised, and I feel good about using clean energy. The customer suport was outstanding, always ready to help. Highly recomend these panels.
One of the best deals for me. Definitely recommend

thnx for the fast delivery and great service! We’ve just finished the installation last week. Panels work fine and id say that for this price they are quite good.
honestly, i found these bifacial panels to be really effective. I’d say that they are a bit more expensive and take a bit more effort to set up, but you really feel the gain in power and they look nicer imo
Good panels with great performance. I love them. Appreciate the free shipping as well!
In my research I ended up with this model because it had the best price among the modules with comparable specs and sleek design. I ended up ordering from A1 because it had the best price. Everything went well, thank you

In the past, I have used solar panels to power RVs and trailers. As soon as I had these Trina panels set up, I could see they were far more powerful than my old ones. Forget the other options, and go with Trina.
Good product, and picking up the panels myself made it very inexpensive. Can't beat fifty cents a watt! Well worth the pick up hassle. The other large distributors I found want you to buy 10+ panels before they'll ship them. I tied four of them on a roof rack (on an EV!), and drove them 25 miles home.
Delivery took quite a bit — turned out it was fedex fault. well, panels aren’t anything special. the design seems kinda average to me. They work fine though. I have a few trees around the house but the shade from them doesn’t seem to make a huge impact on an array so that’s good.

Great panels, I'm buying another system for my new house specifically with Trina panels.
I was completely inexperienced about buying and installing my own photovoltaic system but you guys were exactly what the doctor ordered at exactly the right time. These guys are not your typical online company.

Solid panels, they look and feel just like high-end "American-made" ones. They have a 30 year product warranty (and 25 years of performance warranty), and they have received excellent marks from customers. For our needs, Trina Panels was an excellent choice.

We chose high-quality panels to maximize the output from the roof space on our building. Your store was a find, thank you.
The service was top notch. The panel is fine, good output, okay quality, it’s just that the warranties don’t really impress me, so i’m not ready to give it 5 out of 5.

I purchased 475-watt half-cut cell panels and am extremely satisfied with their output. A1Solar is one of the best stores I've interacted with in my whole career
Trina solar panels were the ones suggested by our installation company. Our short investigation leads us to believe that Trina's panels are of good quality and efficiency at an affordable price. Btw, A1Solar wholesale section is a great way to save
After comparing several panels in terms of price, performance, warranty, and overall value, I settled on installing 45 Trina 480-watt panels. I've been using them for over a month now, and they've been flawlessly reliable the entire time. As a bonus, Trina also has excellent customer service. I needed some clarifications, and they were happy to oblige. Additional panels, if I ever need them, will be Trina.

Really love that you added bifacial panels! My friend had a very positive experience with them so i was eager to try them out. They really feel much more powerful than standard ones.
Affordable and highly recommended on the web. Have only good things to say about these Trina panels.
Great for the planet, great for my wallet.
Panels were selected by my installer, thus I can't comment on them in depth. From what I can tell, they've lived up to the expectations set for them in terms of both cost and effectiveness.
High heat efficiency, extensive warranty coverage, and minimal degradation over time.

I was really worried about the condition of the panels and what I would do if they arrived broken. Luckily it didn’t happen, panels are in good condition, so my experience with the shop has been only positive.
Even if it isn't the most efficient option, it's not far off, and the cost to go with the most efficient one is just not worth it. Also, Trina warranties are awesome.

As a result of the Half Cell technology, efficiency is increased even in the shade. Moreover, these panels have a 30-year guarantee and suffer very little efficiency loss over time. Due to the negligible drop in efficiency, these premium panels are a no-brainer.
Product of the highest quality standards; very functional; constructed to endure. A1Solar did their job above and beyond. Quick feedback, fast deliveries and good prices.

Other panel firms come and go on a regular basis. They boast 25- or 30-year guarantees, but if the manufacturer goes bankrupt, customers have nothing to rely on. Trina Solar was founded before my birth and will continue to operate long after my death. That gives some credence to the 25-year guarantee they provide.

These panels are sleek, and I appreciate that the installer added a skirt to the bottom of them. These all-black Trina panels became even more aesthetic

I liked the service. The panels I haven't been to install yet so we’ll see about them. But the staff knows what they’re talking about and website is well made so yeah
The warranties convinced me, not gonna lie. It’s been two months and I haven't found anything to complain about yet.
Trina is a fine brand, i feel like. the performance in clouds is good indeed. i haven’t been able to test at high temperatures being in new york lol.

I have them installed in Sacramento Valley. The sun is very active here and they generate a lot of power. I plan to add more of these to my setup in the future
Solar power rocks!!! It’s my first system and it feels and looks absolutely amazing. I want to thank the store because the played their part perfectly
In my research I ended up with this model because it had the best price among the modules with comparable specs and sleek design. I ended up ordering from A1 because it had the best price. Everything went well, thank you
Great customer service! I bought them for a project I’ve been working on since spring. They were bulkier than I expected but true to the dimensions on the website. I’m satisfied with the quality, but the panels could be smaller
One of the best deals for me. Definitely recommend
I bought 12 of these for ground mounting on a farm. So far so good. The modules arrived in time and undamaged. It was a pleasure to deal with you guys
I think it’s one of the cheapest models that also offer all-black design. If you want your panels to look cool but don’t want to pay a fortune for it, this might be your choice
Bought one for my trailer, to keep a 200 A golf cart charged on camping trips. It does the job even better than I expected!

I handled the purchase of these panels for our company warehouses in the New York suburbs. The area isn’t really sunny, but these panels perform quite well even on very cloudy days. I’m quite impressed and thinking about getting a couple of panels for my own home.
I run a small shop in Los Angeles and decided to try Trina Solar panels to cover my bills a couple of months ago. If things go the way they do now, these panels should pay for themselves in 7 years or so.
My choice for A1 Solar store was the right one. I appreciate for help and urgent delivery.
Great panels, I'm buying another system for my new house specifically with Trina panels.
Got my order. Everything is working perfectly and my home is running on strictly PV power!
Just received the panels. Everything is perfect, the delivery was due in time.
I ordered Trina 410W Solar Panel and I'm pleased with it. Thank you.
Amazing service! I have been looking for a reasonable solar kit off and on for years. After coming across A1 Solar store I had a few questions. Guys answered my first few random questions in detail. From the first response I felt like I was respected and valued as a customer.
I would like to thank you for the excellent products you provided me to set up a very nice solar system for my home.
I was completely inexperienced about buying and installing my own photovoltaic system but you guys were exactly what the doctor ordered at exactly the right time. These guys are not your typical online company.
Thanks for all your help tracking all the moving pieces in a complicated shipping process, and for the quick answers on installation day. The system went up without a hitch. It was a great help to have someone quick and
accountable on the sending end.
So far so good. Panels seem fine, they generate electricity as advertised and look good. The warranty is great and the price is even better.
Our Trina system has only been in operation for a few weeks but we're impressed thus far. The panels produce great and they look awesome on my roof.
These panels are very efficient. Even on cloudy days they generate plenty of power. I am glad I went with this brand vs expensive panels.
I choose Trina panels for their quality and performance. Also, they fit my budget perfectly. I am happy I found this brand.
I have installed 20 panels on my roof. I can say that they are working because it lowered my electric costs significantly. There is also a big tax refund incentive coming my way!. I love that I’m contributing to helping future generations lower our carbon footprint.
The modules work great now and with the lengthy warranty I feel safe knowing that they will continue working great no matter what.
These modules were as described. The process of purchasing was easy and the delivery was fast. Thank you.
I just received my panels and expected them for possible damage as I was instructed by sales associate. Everything came undamaged. Thank you for fast delivery.
The solar panels' performance is excellent and they are very attractive on my roof.
I am very happy with these modules as they look spectacular and work perfect. I am looking forward to the savings on my electricity bill.
These panels seem to be generating the expected amount of energy. I get a great energy output even during overcast days.
These panels are excellent. They generate energy very efficiently and look very nice on my house. Thank you!
I was looking for budget-friendly solar panels for my cabin. These panels meet all the requirements. They are affordable but nonetheless are very powerful and of high-quality modules.
Hasn’t been long since I ordered and my entire order arrived yesterday. Everything now rests in my garage awaiting my attention!
I just got these panels. Do not know how they work yet but I do like the way they look. Thank you to the team at A1Solar for the help with choosing the panels and the equipment.
Excellent panels! They are very durable, which is something that was very important to me since we get a lot of snow where I live. So far I am very happy with my purchase.
These panels are great! I could not justify spending so much more money just for the brand of a more expensive panel. Trina panels are very efficient and of high quality.
The panels are working very well and they are looking great. I am very happy with this purchase.
These panels are very thin and that was one of the main reason I chose Trina brand. They practically merge with the roof. Great aesthetics.
I am impressed with the service I received here. Customer support specialists answered all my questions when I called ( and I had to call a few times) and I received my modules within 6 days after placing order. Highly recommend.
Very fast shipping! I had my panels within 5 days. Everything came in as described on the website.
I had these panels for about 5 months now and had no problems with them. They did not require any maintenance so far and been working great. Very pleased.
After doing my research, I felt this was the best option for me. These are highly efficient solar panels at a very affordable price.
These are very nice looking panels. I like deep black color and the texture of these modules. They look good on my black roof.
Excellent value for the money! Nice, high quality panels that perform very efficiently.
I bought the modules about 4 months ago and now I can give an honest review. At first I was a little hesitant to go with Trina panels as I was not very familiar with them but I am so glad I did. These panels exceeded my expectations. They are so efficient even on days when I think I won't be getting any power at all! And they look so great. I am hoping they will continue performing like this for many more years.
Since day one, these panels have been working well, generating power and providing me with reliable energy. I gave no complaints at all. I am glad I went with these affordable modules because they look and perform as good as the expensive ones.
Thank you for helping me choose the panels and equipment. I was on a budget but still was looking for quality panels. These Trina panels are perfect for me. Thank again.
Very fast shipping and all panels were delivered in excellent condition.
These were recommended to me by the installer. I was surprised to see that they were so affordable with such a high efficiency rating. So far, I am very happy with the purchase.
The modules have performed above my expectations since day one. I cannot believe such quality and efficiency for such an affordable price.
I have done a lot of research before buying solar panels and have read about different solar panel manufacturers. Trina Solar is a one of the largest solar manufacturers in the world that offer quality panels at low price. That is why I went with Trina panels and I never regretted this decision.
I had these modules installed for a few months now and I can say that they are working very well. I did not experienced any interruption in getting energy. The panels look very nice on my roof as well.
The experts at A1Solar really help me understand the difference between so many various brands of solar panels. They advise me to go with Trina because of my needs and climate conditions. Just completed my order today.

Such affordable prices! I really feel I got a great deal on my solar power system.
We live in Wisconsin and get a lot of snow, that is why I wanted to make sure to buy solar panels that will withstand these challenging conditions. I’ve done a lot of research and decided to go with Trina panels. I have had them for a few months now and we had uninterrupted electricity production throughout winter.

These panels are great! I could not justify spending so much more money just for the brand of a more expensive panel. Trina panels are very efficient and of high quality.

I bought the modules about 4 months ago and now I can give an honest review. At first I was a little hesitant to go with Trina panels as I was not very familiar with them but I am so glad I did. These panels exceeded my expectations. They are so efficient even on days when I think I won't be getting any power at all! And they look so great. I am hoping they will continue performing like this for many more years.

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.
Will my panel produce power in an overcast condition?
While solar panels require sunlight to generate solar energy, they will still work in cloudy weather. Even on a cloudy day, solar panels will produce energy just not as much.
Will my panels produce power if covered with snow?
Solar panels cannot produce electricity if covered with snow.
What is the best direction for a solar panel to face?
The best direction for a solar panel to face is the South
