About product

REC 375W Alpha HJT Solar Panel is a 120 cell monocrystalline module, which is made with heterojunction cell technology that reduces temperature coefficients and eliminates LID.REC 375W Alpha HJT provides higher efficiency and energy yield, even at higher temperatures.The solar panel shows an industry-leading 21.4% efficiency, which makes it an ideal solution for rooftop installations.

  • 375W Power Output
  • 120 Cell, Monocrystalline, Half-Cut Technology
  • 21.4% Module Efficiency
  • N-type technology
  • 1000 Volts Max Voltage
  • High power density of 20.2 W/ft2
  • MC4 connectors
  • Black frame, white back


High Efficiency of up to 21.4%

Great power output and great energy yields are achieved with the help of half-cut cell and heterojunction cell technology, which greatly improves flow of electricity current. REC 375W Alpha HJTsolar panel is equipped withsSpecial anti-reflective glass, which increases light transmission for higher power.

Quality and Reliability

REC 375W Alpha HJTsolar panel features unique advanced cell connections reducing thermal stress on the cells for long-term durability. The manufacturer's automated production improves efficiency and reliability, which explains the lowest warranty claims rate across the industry.

Low Degradation

An industry best 0.24% annual degradation rate results in a performance of no less than 92% of power output by year 25.

Enhanced Frame Design

Super-strong frame is able to withstand up to 146 lbs/sqft. The module can endure extreme loads of up to 7000 Pa.

25 Year Product and Performance Warranty

REC 375W Alpha HJT comes with 25-year product and performance warranties, which cover the panel defects and ensure it performs exactly as it is expected to. The manufacturer claims the panel's output will be at least 92% in year 25.

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.

Good day. I’m not sure how to check if my roof can bear these panels?
Your installer has to inspect the roof before constructing a system. The inspection will determine whether or not you need a new roof for that.
Ok, 375W is goof, but how much power output will I have in 25 years? or in 10 years?
REC panels lose only 0.24% per year. This rate is among the best in the industry. You can expect to have over 92% of the initial power output in 25 years.
Are these Chinese?
REC is a Norwegian company. Their panels are currently made in Singapore.

FAQ

How much is shipping and how long is delivery?
Our standard shipping charge is $195 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
