The solar panels are working well for us. They provide a steady amount of energy but not as much as the datasheet says. i'm told it's normal. Overall, I’m happy with the purchase and would recommend these panels to others.

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

JA Solar JAM72-D30-540MB is a PV module fit for both residential and commercial applications. JA Solar engineers made the Deep Blue series durable and efficient while minimizing the amount of useful space required for their operation. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight. 

Another advantage is the half-cut cell technology. JA Solar has solar cells half the size of those installed in conventional panels. The main benefits are decreased power loss, improved longevity and better low-light performance. As a result, the panel achieves an impressive efficiency of 20.9%. 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. JA Solar paid as much attention to durability as they did to performance. JAM72-D30-540MB is guaranteed to retain at least 84.95% of output after 30 years. Product warranty for this panel lasts 12 years. 

  • 540 W power output
  • 144 half-cut PERC cells
  • 20.9% efficiency
  • 1000 V DC maximum system voltage
  • MC4 connectors
  • 12-year product and 30-year performance warranties


Higher efficiency of up to 20.9%

JA Solar guarantees the highest power output. PERC technology and potent antireflective coating result in 20.9% module efficiency. This is significantly higher than average, which will result in substantial extra savings over the years of operation.

Heat-resistant performance

The heat is less of a problem with this module: with one of the industry's lowest temperature coefficients, JA Solar loses just 0.35% of efficiency for every 1.8°F over 77°F.

Quality and reliability

JA Solar 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. JA Solar is dedicated to quality, safety and reliability to ensure you get the very best.

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 30th year will not surpass 0.45%. After 30 years, the module will still produce more than 84.95% of its initial output.

Improved frame design

JAM72-D30-540MB design makes it suitable for both residential and business rooftops. The use of a strong 1.37" frame composed of anodized aluminum 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.
