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!

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!

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!

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

Hi. Wasn’t REC a European company? Where does this panel come from?

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 Alpha HJT 370W is a 120-cell solar panel by a leading solar company. REC Alpha 370 AA-B is made with heterojunction cell technology to reduce temperature coefficients and eliminate LID. The module offers high power density, which makes it well-suited for both residential and commercial use. The panel shows great performance in low-light conditions, has good shading tolerance and barely ages over the years.
- 370W Power output
- 120 half-cut cells
- 21.2% Efficiency
- MC4 connectors
- Great performance in low-light conditions
Great efficiency
REC Alpha HJT 370W solar panel reaches an efficiency of 21.2%, which is much higher than that of conventional modules. This model generates more energy from a square foot which allows you to use space more efficiently.
Superb performance in low-light conditions
Even when the weather conditions are far from perfect, REC panels perform very well. According to Norwegian engineers, when the irradiance levels decline from standard 1000 W/m² to 100 W/m², the REC 370 efficiency still doesn’t fall below 90%. 3 bypass diodes decrease the effect of shading on the power output.
Outstanding reliability
REC 370W panels are equipped with anodized aluminium frames, which ensure high resistance of PV modules to any possible hazards. The maximum test load of a panel reaches 7000 Pa or approximately 146 lbs/sq.ft — much higher than a standard for solar panels.
No less than 92% of output in 25 years
The REC 370W solar panel loses no more than 0.25% per year. It means the manufacturer guarantees that the panel will retain 92% of its initial power output after 25 years in service.
20 year product warranty and 25 year performance warranty
REC traditionally offers strong warranties for its product. This panel comes with a 20 year product warranty and a 25 year linear power output warranty.
Appearance matters with Alpha Black
On top of being efficient and resilient REC monocrystalline panels look great. The all-black design makes panels look stylish on top of any building. Panels come with a black aluminium frame. Solar cells are protected by 3.2 mm tempered glass with anti-reflection surface treatment
