  • 320W Power output
  • 19.22% efficiency
  • 25 performance warranty, 12 year material and workmanship warranty
  • Withstand wind loads of 2400 Pa and snow loads up to 5400 Pa

Whatever the weather

The VSUN module shows good performance in low-light conditions and high temperatures don’t affect it that much. The power temperature coefficient of a model is at -0.38%/°C

Strong warranties ensure the quality

The VSUN module comes with a 12 year workmanship warranty. The panel loses around 3% of power in the first year after the installation, but you can expect over 80% of its rated power output after 25 years.

High efficiency saves you space

With the VSUN panel you can expect to have 19.22% efficiency. High energy conversion rate ensures that you make the best use of your space.

Don’t fear harsh weather

PV modules come certified for salt/ammonia corrosion resistance and have load certificates: wind to 2400Pa and snow to 5400Pa. Solar cells are protected by a 3.2 mm layer of toughened safety glass and black anodized aluminium frame. These solar panels can withstand a natural disaster and protect your roof from harsh winds as well.

The delivery was fast and i loved your solar calculator. Panels themselves are alright. The power output is just okay, i guess. The design, however, is very very very appealing. Thanks, pleasure doing business with you

Haven’t heard of VSUN before, so I decided to try them out. Didn’t expect much, but so far so good! I REALLY like the design of those. The performance is strong and I start to think that I spent my money quite well.

what is the fuse for it
08/18/2021, 07:00
Series fuse rating is 20A. Read the operating and installation manual for details on fusing.
how long can I expect these panels to last?
07/29/2021, 11:09
The expected lifetime of solar panels is at least 25 years — this is when the warranty runs out. Japanese panels are high quality, so they last for much longer. In theory a panel could live up to 50 years with proper maintenance.

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%.
Do you offer discounts?
We do offer discounts for orders of over 50 units. Please contact us for details.
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
