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.

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.

Is it possible to get a 25 year warranty on the product?
A1 SolarStore
Yes, if the system is installed by REC professionals.

hi. how fast does it degrade? what can i expect in terms of power output in like 10 years?
A1 SolarStore
Hello. REC panels degradation rates are among the best in the industry. They lose a maximum of 0.25% per year, so in 10 years you can expect around 97.5%

Does it come in other sizes?
A1 SolarStore
No, the dimensions are the same for all the panels in this series.

FAQ

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%.
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

About product

REC 370 AA from Alpha Series is a 120-cell solar panel from a well-known manufacturer. The main difference from other models in this product line is the white backsheet. Developed by solar experts from Germany and Singapore, this module combines the best qualities of monocrystalline and thin-film panels. The REC 370 Alpha Black panel offers better performance at high temperatures and fights the shading better.

  • Rated power output: 370W
  • 120 half-cut cells
  • Peak efficiency: 21.2% 
  • White backsheet gives the module a fresh look
  • Better performance at high temperatures
  • Better shading tolerance 

Great efficiency of 21.2%

The efficiency of 21.2%, that REC Alpha HJT 370W provides, is much higher than that of conventional modules. You can use the available space more efficiently with these modules. HJT technology improves the performance of REC 370 watt solar panels at high temperatures.

Improved shading tolerance

“Twin panel” design gives REC Alpha 370W better shading tolerance. REC was the company that introduced this technology in 2014 and it has been used ever since with great success.

Outstanding reliability

30 mm thin aluminum frames of REC 370W panels ensure high resistance of PV modules to any possible threats. A panel withstands 7000 Pa snow loads, according to REC Alpha 370W datasheet — much higher than a standard for PV modules.


20 year product warranty and 25 year performance warranty

Each REC 370 AA panel comes with a 20 year product warranty (25 years if installed by REC professionals) and a 25 year linear power output warranty. Check REC 370 Alpha spec sheet for more information.

Appearance matters with REC Alpha

White backsheet gives the REC panels a new look. REC 370 Alpha Black features an impressive all-black design. These PV modules make any roof stylish and pleasant to the eye.
