how hot can they run before shutdown
A1 SolarStore
Operating range is -40 °C to +85 °C; output will taper off gradually, no abrupt shutdown built in.

can i lay them flat on my RV roof
A1 SolarStore
You can, but tilt improves yield and helps runoff. The warranty stays valid as long as you secure them per LONGi’s mounting guidelines.

Do they look totally black or do you see silver lines
A1 SolarStore
The LR4-60HPB uses black cells, black backsheet, and a black frame, so the front looks uniform and sleek.

What cell tech inside these?
A1 SolarStore
They’re monocrystalline half-cut PERC cells with 9-bus-bar wiring for lower resistance and higher output.

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

LR4-60HPB-365M is part of the LR4-60HPB 355~375M Series — one of the most recent made by LONGi. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight.

To further boost the performance, LONGi employs half-cut cell technology. Each of the panel’s 120 cells is only half the size of a traditional solar cell. This grants LR4-60HPB-365M lower resistive losses and better shade tolerance. At 20.0% efficiency, LR4-60HPB-365M offers surprising performance for its weight and size. The innovations made the appearance of the panel as impressive as the specs. A mere 1.38" thick, this model is completely black with a smooth surface. This beauty doesn’t compromise the quality or reliability of the panel. LONGi provides a 12-year product warranty. Stable power output is also guaranteed — performance warranty will protect you during 25 years.

  • 120 half-cut PERC cells
  • 365 W nameplate capacity
  • 20.0% efficiency
  • 1000 V DC maximum system voltage
  • MC4 connectors
  • 12 years of product and 25 years of performance warranty

Higher efficiency of up to 20.0%

LR4-60HPB-365M guarantees the highest power output. PERC technology and potent antireflective coating result in 20.0% module efficiency. This is significantly higher than average, which will result in substantial extra savings over the years of operation.

Heat-resistant performance

This module makes the heat less dangerous since it has one of the lowest temperature coefficients in the market, losing just -0.34% of efficiency for every 1.8°F over 77°F.

High quality standards

Multiple tests are part of the LONGi tight production requirements, which offer the highest level of quality assurance. Because of the facilities' high degree of automation, the business is able to uphold strict standards and minimize the number of warranty claims to an absolute minimum.

Low degradation for increased lifespan

The amount of power output loss experienced by these panels during the first year of operation will not exceed 2%. The average yearly power drop from the second to the 25th year will not surpass 0.55%. After 25 years, the module will still produce more than 84.8% of its initial output.

Improved frame design

LR4-60HPB-365M design makes it suitable for both residential and business rooftops. The use of a strong 1.38" 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 2400 Pa, guaranteeing that your system will resist even the fiercest winds.

Outstanding all-black design

The panel has a sleek, all-black style that complements any roof beautifully. LONGi uses unique treatment and selection procedures to guarantee optimum cell color. The cells are connected by thinner wires, and from a distance, the surface of the modules seems seamless and smooth.
