I’m an electrical engineer and studied these before buying. Specs are honest, temperature coefficient is better than average, and monitoring confirms they’re hitting 440–445W on good days. High quality construction. Exactly what I wanted.

whats the frame like?
A1 SolarStore
They have a sleek silver anodized aluminum frame that’s thin but strong. It looks nice on residential roofs and holds up well to wind and snow loads.

Are they bifacial?
A1 SolarStore
No, this REC445AA‑72‑XV is a standard mono panel, not bifacial. It only captures sunlight from the front side.

What HJT means
A1 SolarStore
HJT means heterojunction that’s a super efficient cell tech REC uses.

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

Among the newest offerings of REC, REC445AA-72-XV is part of the Alpha 72 series. These panels use state-of-the-art technology to achieve high efficiency and dependability. Heterojunction technology (HJT) is one of the keys to achieving high results. HJT combines the best features of crystalline and thin-film silicon and shows better performance than the industry’s standard PERC cells.

The use of half-cut cell technology is an additional perk. The solar cells of REC445AA-72-XV are half the size of those found in standard panels. Major advantages include reduced power consumption, extended life, and enhanced efficiency in low-light conditions. As a result, the panel achieves an impressive efficiency of 21.0%. REC provides a 25-year REC ProTrust warranty (product, power & labor) and guarantees that after 25 years, performance will be at 92.00% or more.

  • 445 W power output
  • 144 half-cut HJT cells
  • 21.0% efficiency
  • 1500 V DC maximum system voltage
  • Stäubli MC4 Evo 2 connectors
  • 25-year REC ProTrust warranty (product, power & labor)

Higher efficiency of up to 21.0%

The highest power output is guaranteed by REC REC445AA-72-XV with an efficiency of up to 21.0%. Such outstanding performance is the product of HJT technology and an effective antireflective coating. This is notably above average, which will translate into significant additional savings over the course of operation.

Keeping cool in high temperatures

REC445AA-72-XV manages to stay efficient even at high temperatures. For every 1.8°F above 77°F, it loses just -0.26% in efficiency, allowing you to make the most of the sunniest hours.

High-quality standards

REC's strict manufacturing standards include multiple tests to provide extreme quality assurance. The facilities are highly automated, allowing the company to maintain high standards and keep the level of warranty claims very low.

Reliability and degradation resistance

REC guarantees limited degradation over the ensuing 25 years. The performance will only degrade by a maximum of 2% the first year, and then only by a maximum of 0.25% yearly after that. After 25 years, your modules will still show at least 92.00% of nominal capacity.

Enhanced frame design

This model's construction makes it perfect for both residential and business rooftops. Durability and strength are increased by using a strong, robust frame built from anodized aluminum alloy. The model may support a significant snow load of up to 5400 Pa. The panel's back can support 2400 Pa, assuring that even the strongest winds won't damage your system.
