The modules were delivered very quickly. Great customer service as well. It was pleasure to do business with you.
These panels are combination of great performance and great price. So glad I found them.
already survived a heavy hail season without damage, a solid, safe choice for any professional installer.
LONGi continues to be our go-to for reliability. We saw an immediate boost in energy harvest compared to our previous 330W modules.
Our solar installer recommended longi, and we ended up opting for them. They're beautiful, and I enjoy tracking my savings via the app. We saved quite a bit by purchasing here, A1 offered by far the best price for these panels.

About product

Among the newest offerings of LONGi, LR6-72HBD-375MC is part of the LR6-72HBD series. These panels use state-of-the-art technology to achieve high efficiency and dependability. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight.

The use of half-cut cell technology is an additional perk. The solar cells of LR6-72HBD-375MC 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. Given its size and weight, LR6-72HBD-375MC efficiency of 18.6% is quite impressive. And while conventional panels use only one side to absorb photons, bifacial modules employ both sides at the same time. Thanks to the technology, this model can be up to 30% more efficient. LONGi provides a 10-year product warranty. Stable power output is also guaranteed — performance warranty will protect you during 30 years.

  • 375 W power output
  • 144 half-cut PERC cells
  • 18.6% efficiency
  • 1500 V DC maximum system voltage
  • MC4 Compatible connectors
  • 10-year product and 30-year performance warranties

More power and efficiency

An already high efficiency of 18.6% is further enhanced by PERC technology. By adding a solid PID resistance and special glass lamination on top, the manufacturer ended up with an efficient and very durable model. Under standard test conditions, LR6-72HBD-375MC outputs 375 W of power.

Excellent performance in adverse weather

Low temperature coefficient means greater energy production at high operating temperatures. LR6-72HBD-375MC loses just -0.37% of efficiency for every 1.8°F above 77°F.

Quality and reliability

LR6-72HBD-375MC receives multiple quality checks throughout the manufacturing process and is subject to stringent quality and reliability testing. The manufacturing facilities are highly automated, eliminating the risk of human error. LONGi is dedicated to quality, safety and reliability to ensure you get the very best.

Reliability and degradation resistance

Slow degradation over the next 30 years is guaranteed by LONGi. The performance will decrease no more than 2% during the first year and 0.25% annually thereafter. Your modules will retain at least 84.95% of original performance after the 30 years are over. This 375 W LONGi solar panel also comes with a generous 10-year product warranty.

Improved frame design

LR6-72HBD-375MC design makes it suitable for both residential and business rooftops. The use of a strong 1.57" frame composed of anodized aluminum alloy boosts durability and strength. The model can withstand a significant snow load of up to 5400 Pa. The panel's back can withstand 2,400 Pa, guaranteeing that your system will resist even the fiercest winds.

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
