It’s nice to see that bifacial panels also made their way to the market. I think they are a great option and not only for commercial, but for home systems as well. longi panels are good, my friend has them for four years already.

We were looking for bifacial panels for quite a while and eventually settled on these ones. We’ve purchased a batch of those for our shop in California. The service was great, the delivery was on time. Performance is all right. Personally, I didn't like the design of panels too much, but it doesn’t affect the output, so it’s not a problem. Thank you very much. Donovan.

i looked up the datasheet and there wasn’t a 144-cell panel. i’m a little confused, what am i looking at?

A1 SolarStore

144 cell panels are equivalent to 72 cell ones.

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

LONGi bifacial solar panel is a great choice for commercial and utility-scale systems. Bifacial technology increases your energy harvest by up to 25%, compared to standard monofacial panels. This model comes with a 30 performance warranty from a well-known manufacturer.

144 half-cut cell bifacial solar module
440W rated power output
20.2% efficiency
Open circuit Voltage (STC): 49.2V
Warranty: 12 years for product and 25 years for performance

Bifacial technology increases output by 25%

LONGi bifacial modules have solar cells on both the front and the rear side. That allows the module to generate up to 25% more electricity than a standard monofacial panel. It’s especially useful when the space is limited and maximum production is a priority.

Outstanding 20.2% efficiency

Chinese panels reach 20.2% efficiency: much higher than average efficiency rate for monocrystalline panels. High efficiency ensures better energy production from a square foot.

30 year lifetime

The LONGi panel is backed up by a 12 year product warranty and a 30 year performance warranty. Annual degradation is at 0.45%. You are guaranteed to have over 84.95% after 30 years.

Resistant to harsh weather

LONGi panel is made to withstand 5400 Pa wind or snow load on the front side. It is tested to endure 25mm hailstones at the speed of 23 m/s. Cells are protected by an anodized aluminium frame and dual 2.0 mm tempered glass.
