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
Very satisfied with vsun panels. I think this company will do well in the future! Their designers did a great job, I love having these panels on my roof.
The service was great and I really love the panels. Thanks for the tips and advice along the way.
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 standard length of the cables? If these are too short, how do we order longer leads? It looks like they might only be 500mm and that would be too short.

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?

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.

About product
VSUN VSUN405-108BMH is a PV module fit for both residential and commercial applications. VSUN engineers made the 108BMH series durable and efficient while minimizing the amount of useful space required for their operation. This panel takes full advantage of the Passivated Emitter Rear Contact (PERC) technology that allows it to capture up to 12% more energy. All thanks to a reflective layer on the back. This design maximizes the number of photons absorbed by solar cells.
Another advantage is the half-cut cell technology. VSUN405-108BMH 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. At 20.75% efficiency, VSUN405-108BMH offers surprising performance for its weight and size. 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. VSUN provides an industry-leading 25-year performance warranty and a 12-year product warranty.
- 405 W power output
- 108 half-cut PERC cells
- 20.75% efficiency
- 1500 V DC maximum system voltage
- MC4 connectors
- 12-year product and 25-year performance warranties
More power and efficiency
An already high efficiency of 20.75% 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, VSUN405-108BMH outputs 405 W of power.
Keeping cool in hot weather
Even at high temperatures, VSUN405-108BMH remains efficient. It loses just -0.32% efficiency for every 1.8°F over 77°F, letting you make the most of the sunniest hours.
High quality standards
Multiple tests are part of the VSUN 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.
Reliability and degradation resistance
VSUN guarantees slow deterioration over the next 25 years. The performance will decline by no more than 2% during the first year and then by no more than 0.70% every year after that. After the 25 years are over, your modules will retain at least 81.2% of their original performance. This 405 W VSUN solar panel also comes with a substantial 12-year product warranty.
Enhanced frame design
VSUN405-108BMH design makes it ideal for residential and commercial rooftops. Strong 1.18" frame made from anodized aluminum alloy increases durability and strength. The model can support a heavy snow load up to 5400 Pa. The back of the panel can handle 2400 Pa, ensuring that your system will survive the strongest of winds.
