These 410w panels just arrived - I like the package and overall design so far. we'll see how they perform after the installment. thanks A1Solar
good enough for my needs. the panels are doing their job and generating the expected amount of energy. had a small issue with one panel, but it was resolved quickly.
Qcells panels are super efficient. Totally recommend
WE purchased these for second time LOVE'em work great.. Power even in low light conditions .A1 solar EZ to work with will return soon for more.
an excellent panel, great output, even clouds arent a problem. the service was good, might come again soon
The brand reputation and dependability of these solar panels are its greatest features. A1 SolarStore gave me the best customer experience ever!
Replaced my 12-year polycrystals with these Gain was almost 40 % Totally worth busting the old racking
you really start to outshine the competition with how you do business! much love. Wes
the solar panels work well and provide a steady amount of energy. installation was simple and quick, although the instructions could have been a bit clearer. overall, i'm happy with the purchase and would recommend you.
choosing the right solar panels was a daunting task for me. i had no idea where to start. your staff took the time to explain the differences between the various options and helped me make an informed decision. their advice was spot-on, and the panels are performing wonderfully. i'm so grateful for their assistance and will definitely be back for more!

In general, i enjoyed shopping at a1 solarstore. The staff was very nice. their prices are solid, although confusing at times. but the communication is on point and i got the order fast.
had a positive experience with these panels. they are working fine.
Very good panels. solid brand, as far as i can tell. so far, they perform nicely and the bill has indeed decreased tremendously.

The service was really good. very clear instructions, helpful staff and fair prices. the panels though..not quite what i was expecting. they never got to these 485 they promised...other than that - pretty good
Best prices on solar panels I could find. Saved me a lot of money!
Love our new solar panels! Lower bills and eco-friendly
Easy installation and instant savings
Purchased four panels for an outbuilding roof install. Panels are performing as expected. Pickup at the facility near me was quick and easy; even though it was only four panels, they were palletized and loaded into my truck for me.

High density, 485W cells that are quite efficient so far. 14 is all that i managed to fit on my roof
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.
I was unsure which solar panels to choose because there were so many options. your staff provided exceptional guidance, answering all my questions and helping me make the right choice. the panels were delivered promptly and have been performing wonderfully. i'm very pleased with the whole experience and will certainly return for future purchases.

Ordered QCells 410 panels, everything works fine. Waiting for the next electricity bill to see it it's worth it

Good looking panels, and they perform admirably with respectable efficiency.
Great people to deal with EZ ordering / pickup .. These Q panels really work well our second order will soon be purchasing again.
One of these panels was struck by two errant golf balls soon after installation. It's interesting that the production of power was hardly impacted. Really built to last
WE purchased these for second time LOVE'em work great.. Power even in low light conditions .A1 solar EZ to work with will return soon for more.
i find these solar panels to be satisfactory. they were easy to set up and are providing a consistent energy output. the customer service was helpful when i had questions.

The Q CELLS panels are excellent and generate a respectable amount of power per panel. We need as much efficiency as possible because they face east and are partially shaded during the winter months by a neighbor's tree.

Qcells panels are super efficient. Totally recommend
Panels and optimizers appear to be operating as intended, however due to the panels' current location (it’s summer), they experience shading issues. Due to this, we have not yet reached full output (the building is not perfectly located or orientated, which is obviously not A1Solar’s fault). We'll have to wait and observe how the change of seasons affects the issue.

For more than 7 years, our organization has installed Q Cells modules, and we have never encountered a performance issue or a technical fault. When contrasted with other companies, their modules' pricing point offers a superior cost-benefit.

Honestly, I’m clueless in solar panels, but they're doing fine. Silent heroes on my roof, saving me some bucks.Thanks to ingeneer Vic for advising
Got these panels just unboxed; the package was solid, and the manager's assistance made the buying process hassle-free.
Great product LOVE the Q cell panels. Quick EZ ordering/Pickup .. Very helpful at warehouse Your system saves $$$ and makes whole purchase a JOY.. Will be reordering more panel's in spring

I'm very glad we opted for QCells rather than the blue/gray panels. Since they are so black, it is difficult to notice the QCells on the roof. Additionally, they generate at almost full capacity for a long time, and their efficiency declines very gradually .
Please send Vic my thanks for a great recommendation
I was choozing between 405w and 410 qcell modules. The nearest pickup location had these in stock, and I'm satisfied

Currently waiting to get my first bill. I’m expecting at least a 90% reduction, but we’ll see. Going with the integrated microinverters was the right choice. Allowed for a faster installation and now the system is yielding more as a whole

The system is operating more effectively than I had expected it would. Since the month of November, I have not made a payment on my power bill. My power bill has consistently shown that I had a credit balance since that time. My experience with the system has been completely problem-free. It has withstood multiple hailstorms without suffering any form of harm whatsoever.

On bright, sunny days, the Q cells have consistently peaked at their maximum output capacity. The integrated microinverters really help with shading in the morning and evening. We can only hope that they keep performing like this for the rest of their lifespan.

I couldn't be happier with both the solar panels and the outstanding customer service. From initial consultation to post-installation support, they were friendly, knowledgeable, and responsive. The panels are top-notch and have exceeded my expectations.
Qcells panels are super efficient. Totally recommend
These Q Cells panels are sleek, efficient, and generate energy even on cloudy days. We have noticed a significant decrease in our energy bills since we installed the system. We would highly recommend this solar panel to anyone who is looking for a reliable and high-performing option at a very attractive price.
I'm absolutely thrilled, they exceeded my expectations in terms of performance and energy savings. highly recommended for anyone considering solar power.
Reasonable Cost with Premium Quality
I recently purchased a few of these Q CELLS 320W Solar Panels for my home pool and I am extremely satisfied with their performance. As an engineer, I appreciate the high efficiency and durability of this model. The sleek black design also blends in nicely with my home's aesthetics. The thing the spoiled the fun a little was a single cracked panel at the bottom. At least A1 replaced it without hassle. The transportation service should be more careful

It's compact, efficient, made by a German quality and only a little above $200. Pure gold.

Meeting the average expected generation on which the financial analysis was based has made us extremely satisfied. Tree shade was a major concern, but the integrated microinverters are up to the task.

A1Solar processed the order the day it was placed and we got the delivery 5 days later. Excellent service. The system operates properly and generates electricity from very early in the morning until late in the afternoon.

My friend's panels perished precisely 12 years after they were installed, so he had to replace them, which cost him a lot of money. I got the 365w panels with the 25-year warranty, giving me peace of mind that they will last a long time.

Many thanks for the split payment functionality, you’re the best solar equipment store!

We started with the minimum order of just six panels and plan to add regularly to our system. It is extremely easy with these Q CELLS panels - each has a built-in inverter.
Good service, affordable equipment, have bookmarked you for my future solar needs
I actually love q cells and i recommend them to all my friends to the point that they tell me to shut up about it. but seriously, the price is not that much higher than chinese panels, but i feel like the panels themselves are superior. 25/25 warranties are no joke either
I ordered a pickup because one of their centers was nearby. So I drove there and got the order, checked it on the spot just in case. They warned me about driving carefully and all that. I delivered the package home safely. good experience overall.
Great service. Very satisfied with how professional the stuff was.
A1 SolarStore staff handled my order very professionally and the delivery was on time. The panels themselves are very good-looking and they indeed do well on bad days. It feels like engineers finally figured out how to deal with clouds and bad weather in general.
thank you, I was just looking for something like this.
a very very good performance in clouds. I expected less to be honest, but this is a top-tier product.
q cells panels are actually always a safe bet imo. i know a lot of guys with solar panels, and not one of them was ever disappointed with going for qcells product.
Me and my brother bought a bunch of those and installed em in the yard. we actually plan to use it for mining. The panels are goooood. they are good, man. i feel like i have a small power plant by my house, that’s a whole lotta power. tnx, peace
We purchased a sizable amount of these panels half a year ago for our enterprise in California. The installation was finished just recently. So far the panels have allowed us to lower our energy expenses by 62% and we expect even more from them in the following months. Many thanks to A1 SolarStore staff who handled the order very professionally and helped a lot along the way.
thank you very much
people told i’m stupid for going solar in New York, but i feel like i proved them wrong. This panel does amazing here, even though we have lots of gloomy days and stuff
Thanks for wonderful service and for recommending the panel. I love the output and my wife says they look great on our roof.
the look is a solid 10
performance is great
i really haven’t found anything bad about this panel and believe me, i’ve looked
The quality for the price is ok thanks A1 solar
I bought these panels in the middle of the spring and right after the installation there was a tornado here in dakota. but the panels survived it very well to my surprise. I obviously had to clean them afterwards, but the production was the same. great stuff.
Awesome store, keep it up!
Got these panels installed as soon as my delivery came they look great on my roof
Even though these panels are more affordable than other brands I am not disappointed with the efficiency so far they have been running smooth
I don’t have a solar plant, not even close, but I figured that if it lowered costs for industrial setups, it could do the same for me. My plan worked, I’m definitely satisfied with my purchase.
We’ve purchased a batch of QCELLS panels for our gas station in Oklahoma. The staff of a1solarstore was super professional. Since our order was big, we even received a little discount. As for panels, they perform amazingly and we are very happy with our choice. Thank you!
Just ordered great panels from a1. The order processing was almost instantaneous. Looking forward to delivery.
None of the fears I had about going solar came true. The store handled my order very professionally and they didn’t give me any surprises
Surprised no one mentioned how beautiful these panels are. it’s the last thing I thought about tbh, but they look perfect on my roof.
Very good service, thank you!!
Excellent build quality and impressive output. The modules are 50 ft away from the inverter and the system works great. Would recommend to a friend
Your solar calculator was of great help, a super useful tool! Thanks for the fast delivery, we began the installation two days ago.
These are not premium panels and I won’t lie that there’s no difference, but the price is also way lower. A1 does a great job, keep it up guys!
I picked up the panels myself at Pennsauken, following your guidelines about transporting panels. So far so good… My installer is currently in the last stages of getting a permit. Thank you!
The panel is quite heavy, and i had to reinforce the roof for a PV system. I’m also not a fan of the look. But its properties are very good and the performance is outstanding. It’s a good price for QCells product and the service that the shop provides is on point.
You simply can’t find anything better at this price. The performance is great and the modules are also designed in Germany. I would recommend it as the best budget option.
The delivery was a little delayed, but turned out that it was Fedex to blame. Otherwise, really happy with my purchase, tnx
I had solar before and decided to go for an upgrade. Honestly, was impressed, these panels are much more efficient than my previous ones.
Compared to other brands, the price of Q CELLS modules is a major advantage. We have been installing them for our clients for more than 8 years and never had a single problem with performance or craftsmanship.
The process of purchasing was efficient and easy. Tracking updates were provided and the shipment arrived on time and in perfect condition.
Just had them installed. Seems to be pretty good so far! I used one for the garage, even though this is classified for the attic and the garage seems to be cooler than with nothing on the roof other than the. Eating hot sun!
I actually don’t think I have experienced such proactive customer support before and you should be commended for this. Thank you.
It shipped as promised. Arrived in perfect condition. All my questions were quickly responded to.
We have a small 17 foot camper trailer and wanted to be able to camp without plugging in. We are now able to use our water heater, refrigerator, water pump, radio, and cabin lights while the solar panel recharges our battery during the day. The unit is easy to use and seems to be well made.
Everything went well. The installers were efficient and polite, and after sales service has been attentive and effective.
I searched for an off grid solutions for 5 years. Finally discovered A1 Solar store. WOW what a welcome change, finally people who knew what options and equipment to put together and how we can build a lifestyle not crimped and scavengers in the wilderness.
My experience with A1 Solar has been one that I could not rate highly enough. Everyone from the first phone call to the last has been a pleasure to deal with. All requests were dealt with promptly and without question. The pricing was competitive from the start. I appreciate it.
It was the first time I bought solar panels, and I needed some advice. Guys from A1 recommended this panel for my needs. So far so good
I would like to thank you guys for the perfect job and help you gave me with the choice of the panels.
Just wanted to thank all your co-workers in working with me. This has been the best customer service.
Thank you for your professional service and help. The way you handled my order is beyond words.
I enjoyed working with you and trust your service and will continue doing business in the future.
I just wanted to take a moment to express how wonderful my experience with your company was.
The delivery was fast, the panels arrived a couple of days ago. Looks like they are the right thing for me. Thnx
You Guys ROCK! Thanks for your awesome customer service and technical support. I am so pleased with the products you sold me.
Thank you very much for your patience and assistance in working with me on this system.
Our goal was to be able to remain in our home during the extended power outages after hurricanes strike our rural northern Florida area. So I found A1 and was pleased by working with these guys. Great job.
Thank you very much for all your help. Customer service is everything!
Team members at A1Solar are very professional, kind and helpful. They do care about their customers and keep their customers’ best interest in mind. Plus, they do offer very competitive prices.
Hi everyone,I just wanted to extend a big “thank you!” to your entire team. I am extremely pleased with my recent order and I can’t wait to get it installed. Every step of the process has been great and the people I spoke with on your team were cheerful and helpful.
The panels work very well. The pricing was very competitive. The warranty is better than the majority of solar brands offer. The system meets my needs exactly.
I picked these panels because of their efficiency. Their efficiency can be compared to the most expensive solar panels on the market but they cost so much less. What a great deal!
These black panels look great. They also have an awesome warranty for their affordable price. I am hoping they will last a long time.
We decided to go with Q-Cell solar panels because of their excellent reputation, quality, and warranty.
These panels came highly recommended by my installer and so far I haven't had any problems with them.
Choose Q-Cells panels because of the great performance to price ratio plus their great warranty. I feel like I got a great deal.
I haven't had the system long, but it seems to be working well so far. It looks great as well.
One of the best looking panels on the market that are priced very competitively.
Just got panels delivered to my driveway and they look amazing. Black on black will look awesome on my roof.
