About product

Emerging from REC’s leadership in half-cut cell technology, the Alpha is built around 120 half-cut heterojunction cells (HJT) and advanced connection technology, designed by engineering experts from Germany and Singapore. With REC Alpha 365, the engineers have really excelled themselves in trying to make a modern and reliable PV module. With HJT, REC combines the benefits of crystalline silicon solar cells with those of thin-film technologies for much higher efficiency and energy yield, even at higher temperatures. This REC Alpha Black 365 is great for commercial installations, but can be installed on the roof of your house as well.

High Efficiency up to 20.9%

Every REC solar panels review mentions how powerful these modules really are. With the REC Alpha Series, customers get over 20% more power from the same area and the same number of panels – the same energy output from less space. This reduces the Balance of System (BoS) costs.

High Efficiency at High Temperatures

Leading temperature coefficient means less energy loss as temperature rises. A REC 365W solar panel works amazingly even at high temperatures. No LID (Light Induced Degradation) = no power loss. You get the power you pay for. More power output thanks to low NMOT (Nominal Module Operating Temperature): 44 ± 2°C.

Quality and Reliability

The company always makes sure that REC 365 Alpha doesn’t disappoint their clients. REC’s many tests guarantee extreme quality assurance. Through advanced cell connection technology REC eliminated invasive soldering of solar cells and removed the risk of cell damage or microcracks for long-lasting high performance. Thanks to REC’s award-winning ‘Twin Panel’ design, the company was able to reduce internal resistance for more power and reliability.

Low Degradation

REC 365 Alpha Black is really a long-lasting panel. Industry’s lowest 0.25 % annual degradation rate results in at least 92% of nameplate power in year 25, which is the best in solar manufacturing and 15% more than with traditional modules.

Enhanced Frame Design

REC’s unique 30 mm frame design allows more panels per pallet, an easy installation, and allows the Alpha to withstand snow loads of 7,000 Pa. Added ammonia and salt mist resistance makes this module an excellent choice for installations at seaside, farms, and other harsh environments.

20 Year Product and 25 Year Performance Warranty

  • 20-year product warranty (25 years on installations by REC Solar Professionals): covers any panel defects
  • 25-year performance warranty: ensures panels perform exactly as they’re expected to – every year for 25 years
  • 25-year labor warranty: gives added protection in case a panel needs to be serviced

We do no sell racking at this time.


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
