About product

REC365AA solar panel represents a well-known REC Alpha Black Series. Panels from this line combine the qualities of monocrystalline PV modules and some of thin film panels. As a result these PV modules show outstanding performance especially at higher temperatures. They are suitable both for residential and commercial-size installations.

High efficiency even in low-light conditions

REC panels always offer high efficiency which allows their customers to save more space when building a solar system. REC365AA offers 20.9% efficiency. Its performance barely drops in bad weather. The tests show that when irradiance drops from 1000 W/m2 to 100 W/m2, the efficiency only decreases from 100% to 90%.

Outstanding design

Customers love all-black design of panels that REC provides. The panels from Alpha Black Series look stylish on any roof.

Durable and long-lasting

REC panels aren’t just beautiful, but durable and resistant as well. The frame is made from anodized aluminium, the cells are protected by 0.13 inch layer of glass. Panels are made to withstand 7,000 PA snow load and 4,000 Pa wind load. A REC PV module loses no more than 0.25% of its power output per year and the customer is guaranteed to have over 92% of initial power after 25 years.


  • Efficiency: 20.9%
  • 20 year product warranty and 25 year performance warranty (92% after 25 years)
  • Maximum annual degression: 0.25% per year
  • Dimensions: 67.8 x 40 x 1.2 in 
  • Weight: 43 lbs

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.

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.

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”.

Yes, you can get them at one of our warehouses. The list of available pickup locations is below the price.
Their website says 25 year warranty for this panel?
07/04/2021, 16:24
The 25 product warranty is issued when the panel is installed by REC professionals, but otherwise it’s 20 years.


How much is shipping and how long is delivery?
Our standard shipping charge is $250 for up to 11 panels and it is increased by $25 for every 4 additional panels. 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%.
Do you offer discounts?
We do offer discounts for orders of over 50 units. Please contact us for details.
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
