I like that these panels are eco-friendly and help me reduce my carbon footprint. Plus, they look sleek on my roof!
The efficiency is great, but I wish they came with a better monitoring app. Otherwise, no complaints!
REC panels are solid best looking black panels ive seen
Great quality for the price. The installation was smooth, and the performance is excellent even on cloudy days.
I’ve been thinking about installing panels for a while now but was worried about my limited space these panels have been a good choice they are really powerful for their compact size.
I was confused about which solar panels to buy but the customer service team was amazing, answering all my questions and providing expert advice. they walked me through the options and helped me understand the benefits of each type. with their help, I made the right choice and am very happy with the panels.
Durable and efficient. We had a storm last month, and the panels held up perfectly without any issues.
Really worth the price on these panels the power output is really great and completely cut out my power bill.
Found everything I needed for my solar project at A1 SolarStore. Great prices too!
Installed these panels six months ago, and my electricity bill has dropped by 70%! Super efficient and easy to maintain.
Great service I picked up my panels they have been running smoothly since installation.
Solid build and great warranty. Customer service was helpful when I had questions about installation.
Delivery was super fast and the panels were in perfect condition. Great job!
The glass of 2 panels was broken but the guys quickly replaced them with new ones. Already installed the system and waiting for the next bill to see results
I was skeptical about going solar due to cost, but A1 proved me wrong. The pricing is reasonable, and the panels are performing exceptionally well, already seeing the benefits
i'm getting a steady output of energy from these panels. happy with the purchase and the reduction in my electricity bill. the setup was straightforward, and the panels are working well.
Good performance overall, but I had some trouble with the initial setup. Customer support helped me out, though!
Great service I picked up my panels they have been running smoothly since installation.
I pleasantly surprised by the prices that this shop offers and the level of customer support that they provide. Many thanks to the engineer who stopped me from making a costly mistake when picking equipment
panels are good, but the installation process was a bit more complicated than I expected
I recommend making the switch to green energy the process is easier than I expected.
Picked up from their warehouse, was so easy, happy with my purchase
Panels are amazing and the delivery was super fast, A1 the best
Good prices and good reliable products

customer service was excellent and the delivery was quick. would recommend to anyone
Very good panels
thanks! hope to see you expanding to Canada soon
Everything turned up great, so we really appreciate your patience. Our most successful endeavor to date! What a relief it is to have solar panels and be able to use sustainable energy. This store, A1Solar, gained my highest recommendation.
These are decent. They generate a fair amount of electricty, but sometimes they're a bit inconsistent. Not the best, but not the worst either.
Everything perfect, thanks

i'm super impressed with these solar pannels! they're reliable, and the savings are real. definitely recommend!
The REC panels exceeded my expectations in both appearance and quality. The only disadvantage is It's not the most well-known brand.
very good panels. we plan to return next month for a batch for a new installation in the south-west
These are decent. They generate a fair amount of electricty, but sometimes they're a bit inconsistent. Not the best, but not the worst either.
Our relatives told us about A1. We’re passing on the recommendation - the store is reliable and honest. Picked the panels ourselves, so nothing to say about the delivery

The panels were shipped by the company I trust and arrived undamaged in under a week. A1Solar are very fast, responsive and diligent. I was lucky to end up making my first equipment purchase here
I got my panels shipped to my address and they arrived within a week. I was worried about damage during shipping but they were all in perfect condition.
I received a pallet order within 5 days of purchase. Drop shipment with liftgate right to my garage. Very fast!
Panels were in great condition upon delivery and they work very well!
I have mixed feelings about these solar pannels. they're reliable, they generate a fair amount of electricty, but just cost a bit tto much.

Slimmer than the first solar system we owned. It's also superior in every respect, including cost, quality, guarantees, and productivity.
Premium quality and looks, but quite expensive. If you want the best panels and super eco-frindly on top of that, look no further

Up until this point, everything has been OK. Affordable, high-quality, and stylish all-black panels. That's about as good as it gets!
We first decided on these panels as they are space efficient. My wife and I are greatly satisfied with our new solar system since having it installed three months ago.
The REC panels exceeded my expectations in both appearance and quality. The only disadvantage is It's not the most well-known brand.
Am in love with these soler panels! they're highly efficient, durable, and have significantly reduced my electricity bills. a worthwhile investment for sure.
Wow, these solar panels are legit! They're like little powerhouses. My electricity bill dropped big time after installing them. Highly recommend if you wanna save money and be eco-friendly
Before choosing a brand of panels, we did some reading and talked to our installer. Since Tesla is the first brand that springs to mind, that's the one we were leaning toward. Unfortunately, we had second thoughts after reading some bad Tesla customer service ratings. It was explained to us that REC were just as nice, if not better looking, and came with the same warranty as the more expensive brand. We don't regret this decision
i think rec probably has the best solar panels on the market right now

My spouse done a ton of homework on the various solar panel manufacturers and types of panels. To save money without sacrificing quality, we went with these REC modules.

It was recommended by our friend who works in solar. We liked the all black look and reputable brand.
Initially wanted another model but it wasn't available for a while, so picked this one. System still not finished, but a friend has REC panels, no issues for years.

When we researched the panels online, we found that they were highly rated and virtually indistinguishable from high-end options. A1Solar is a find

So far, these REC panels have been doing admirably. Mounted so low to the roofline, I hardly even realize they are there, which is a relief because I was afraid they would detract from the beauty of the house.

design -top notch. performance is very good as well
Premium quality and looks, but quite expensive. If you want the best panels and super eco-frindly on top of that, look no further
The service is great and the delivery was on time.
The panels themselves look high quality and do produce a lot of power. So far I'm quite satisfied — we’ll see what the future brings.
thank you for the recommendation earlier! i was really wondering about this split cell technology, cause i needed something to fight shading well. This one does alright!
Not the most modern, but still a great panel and for a really fair price.
I have had one of these on my RV for 3 years now - its brillant. i paired it with my 300amp hr Lifepo4 battery via a 20 MPPT EpEver. The performance barely changes on rainy days. very impressive.
We’ve put these panels on our farm in Colorado. Now we need grid electricity only at night! I basically stopped paying energy bills since the purchase, so they should pay back for themselves in less than a decade.
Oh, I know this module! My friend has had it for a couple of years already. He said that it’s a great module to have and he really likes rec panels in general
rec is a great brand in general. all of their panels are very well made
I’ve been thinking about installing panels for a while now but was worried about my limited space these panels have been a good choice they are really powerful for their compact size.

Good value for money. I’m gradually building a system, right now I have 14 panels. I like how they sit on the roof i think they give a house a very modern look
Really worth the price on these panels the power output is really great and completely cut out my power bill.
These panels are unbelievably thin, but at the same time much sturdier than many thicker modules because the frame is reinforced. I guess all respectable panels work as they should, but these also look great
I recommend making the switch to green energy the process is easier than I expected.
A1 team is really easy to get ahold of and quickly responded to my emails Thank you guys
The website is really helpful and directed me toward this product that is well suited for my home. There is plenty of useful information in the product descriptions and they answered my question the following day.
I guess for this price range it is either this or panasonic... honestly I like REC more. the design, the performance, the quality — all top notch. Maybe they don’t do such an awesome job when it comes to dealing with shade, but it already feels like nitpicking.
They look so GOOD. Honestly, even if they didn’t do a thing, I'd still be glad to have them on my roof just to style on everyone. but boi, they do a lot. I don't even pay for electricity anymore.
We first decided on these panels as they are space efficient. My wife and I are greatly satisfied with our new solar system since having it installed three months ago.
Good prices and good reliable products
Looks nice, great quality and amazing service!
just got my package. everything seems to be in place. We'll start the installation in a week, i think. tnx.
Heard a lot of good things about REC and decided to try these panels two months ago. Very satisfied. They deliver no matter the weather, I don’t even understand it. a1solarstore also did a good job: the customer service was on point so thank you for that.
The performance is good, but i’m not writing about that. I installed the panels and my neighbor complimented the look of my roof with PV modules today. Didn’t expect that at all.
yeah, the panels are a little expensive, but the amount of energy they generate justifies it. it’s summer and my installation makes at least 30 kw daily even when it’s cloudy, it’s amazing!
thanks to a1solarstore for the help! they helped in sizing the system and recommended this model. The delivery was fast and we’ve just finished the installation today. it’s too early to judge on the performance, but they look amazing, sturdy, and very high-quality.
We’ve just finished constructing the system and launched it. It’s a bizarre feeling to have a little solar farm on your roof. The shipment was fast and our order was handled very professionally. Thank you very much!
I’ve been using these panels for half a year now. These aren’t my first panels, but these are certainly much more powerful than what I used back in the days. i chose them cause they age slower, so my children could make use of them in the future.
REC just doesn’t disappoint. the price may look a little scary, but when the panels arrive and you look at them you just go “whoa”.
I often had my panels lose a lot of power under the sun in summer here in Phoenix. some even warp. But these ones perform amazingly! The quality makes them really worth their money.
I loved the service particularly. The calculator helped in sizing the system, then the package arrived about a week after I made the order. The panels look great, I've put them in the garage until the installation. Thanks a lot!
The shipment came. everything is in good shape. I haven’t installed the modules on the roof yet, but checked them in the yard, they work. Thanks, pleasure doing business with you.
I liked the service. the calculator really helped in sizing the system and the package arrived quite quickly. As far as the panel goes, time will tell, but it looks really good.
Recently there was a huge tornado here on the West Coast. there must have been 80 mph wind or something like this. These panels endured it without a scratch. I'm so impressed, thanks a lot!
Speaking from experience, REC panels are goood. They cost a little extra, but bring in a lot of energy and are really sturdy as well! Here in Florida the weather can be harsh, but they never let me down.
I was told several times that REC panels are expensive, but honestly to me they are worth every penny. They look good! they look solid, reliable, not just like some cheap chinese crap. I installed them a half a year ago and they outdid my expectations. Even the shading wasn’t that much of an issue. Thanks a lot
The panel is worth its money. i checked and it barely loses power even when it's super cloudy here.
Yeah, i think i like this look better than alpha black series. more distinctive and it screams high-quality. guys, if you haven't checked out REC panels, you better – can’t go wrong with them!
Me and my husband decided to buy panels as a long-term investment project. The staff of A1 was really nice and helpful. In the end I picked this model, mostly because of the looks and its durability. The package arrived safely, the installation is complete – so far everything is working perfectly.
Thanks to your excellent website and all the help it offers. I am deeply pleased and impressed with my purchase.
Thank you for providing me with quotes for solar panels for my home.
A1 solar was a pleasure to do business with. The guys returned my emailed questions with a phone call or email back almost immediately every time!
What can I say other than the best quality of product and even more important. The best support that one could wish for when choosing to take on a solar project of any size.
I just wanted to let you know how happy I am with the system that I bought from you . When it arrived, every single component was there. I recommend your company every chance I get.
My experience was amazing while working with this company and yours will be too! They put the SOUL in SOLAR……..
If you want to work with a solar company that honestly wants to help you, A1 Solar store come with my highest recommendation.
Just to let you know I have had my solar installed. Based partially on your recommendation. I would recommend your company to anyone looking to install solar.
I was looking for an affordable option but still something reliable. The warranty the company offers is amazing and really makes me at ease to make such an investment. Panels look very sleek, will update my review when know more of their performance.
Wonderful panels!!! What a great innovation in solar technology to enhance the efficiency of solar modules. Hats off to REC team for such an amazing product! And thanks to A1solar for a great customer service.
Compared different panels across the board, and the 20 -year product warranty really sold us as did the quality and efficiency of the panel itself. Also, can't beat the price of these modules.
Bought 10 panels for my cabin, could not be more happy with my purchase. Quality of the panels exceeds its price.

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?

About product
REC445AA72 is part of the Alphα 72 Series — one of the most recent made by REC. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. This panel takes full advantage of the Passivated Emitter Rear Contact (PERC) technology that allows it to capture up to 12% more energy. All thanks to a reflective layer on the back. This design maximizes the number of photons absorbed by solar cells.
Another advantage is the half-cut cell technology. REC445AA72 has solar cells half the size of those installed in conventional panels. The main benefits are decreased power loss, improved longevity and better low-light performance. Not surprisingly, the efficiency of this module is quite high – 21%. REC provides an industry-leading 25-year performance warranty and a 20-year product warranty.
- 445 W power output
- 144 half-cut PERC cells
- 21% efficiency
- 1500 V DC maximum system voltage
- Stäubli MC4 Evo 2 PV-KBT4-EVO-2 connectors
- 20-year product and 25-year performance warranties
High efficiency of 21%
REC Alphα 72 panels have a high efficiency of 21 percent and take full advantage of the company's technologies, which have won REC several honors. This PERC option produces more electricity per square foot of PV modules. This translates to shorter installation times and fewer clamps and racks. All of this lowers your overall expenditures and shortens the payback period.
Exceptional performance in hot temperatures
A low temperature coefficient provides more energy output at high working temperatures. REC445AA72 loses just -0.26 percent efficiency for every 1.8°F over 77°F.
Quality and reliability
REC445AA72 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. REC is dedicated to quality, safety and reliability to ensure you get the very best.
Reliability and degradation resistance
REC guarantees slow deterioration over the next 25 years. The performance will decline by no more than 2% during the first year and then by no more than 0.25% every year after that. After the 25 years are over, your modules will retain at least 92% of their original performance. This 445 W REC solar panel also comes with a substantial 20-year product warranty.
Improved frame design
REC445AA72 design makes it suitable for both residential and business rooftops. The use of a strong 1.18" frame composed of anodized aluminum alloy boosts durability and strength. The model can withstand a significant snow load of up to 5400 Pa. The panel's back can withstand 2400 Pa, guaranteeing that your system will resist even the fiercest winds.
