panels are great work good. my installer said they are top quality. producing good numbers every day. only reason not 5 stars is i wish they came with some kinda bag or cover for storage before install but thats minor

Got 10 of these for my home system and wow. Production numbers are even a little better than what my installer estimated. The bifacial design definitely helps with my white roof. Couldn't be happier

How long will these panels last?
A1 SolarStore
Solar panels of this quality typically last well beyond 30 years, and many installations continue producing power at 40+ years with reduced output. The 30-year linear performance warranty gives you added peace of mind. Proper installation and occasional cleaning are the best things you can do to maximize their lifespan.

do i need a special inverter for a bifacial panel
A1 SolarStore
Not necessarily — bifacial panels work with standard string inverters, microinverters, and power optimizers, just like regular panels. However, to fully take advantage of the bifacial gain, you'll want an installer who can orient and mount the panels to maximize light hitting the rear side. Some monitoring systems can also help you track the extra production.

Can I install this on a metal roof?
A1 SolarStore
Yes, this panel can be installed on metal roofs using the appropriate mounting hardware. The panel comes with a standard aluminum frame that is compatible with most racking systems designed for metal roofs, such as standing seam clamp systems. We'd recommend working with a qualified installer to choose the right mounting solution for your specific roof type.

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

Mission Solar MSH10-590HN4G is a PV module fit for both residential and commercial applications. Mission Solar engineers made the N-Type Bifacial 144HC Dual Glass series durable and efficient while minimizing the useful space required for its operation. Half-cut cell technology adds a few more percentage points to overall performance, making this model a great example of efficiency. Mission Solar made solar cells in MSH10-590HN4G two times smaller than the standard size, thus reducing power loss and improving low-light behavior.

Not surprisingly, the efficiency of this module is quite high – 22.8%. 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. Mission Solar provides a 15-year product warranty. Stable performance is also guaranteed — a warranty on power output will protect you for 30 years.

  • 144 half-cut TOPCon cells
  • 590 W nameplate capacity
  • 22.8% efficiency
  • 1500 V DC maximum system voltage
  • MC4 EV02 / MC4 connectors
  • 15-year product warranty and 30-year warranty on power output

High efficiency of 22.8 percent

Mission Solar N-Type Bifacial 144HC Dual Glass panels fully use the firm's innovations, for which Mission Solar has received several distinctions. With TOPCon technology, more electricity can be produced per square foot of PV modules. As a result, there will be fewer clamps and racks required during installation. All of which lowers your overall expenses and accelerates the payback period.

Heat-resistant performance

The heat is less of a threat with this module: with one of the lowest temperature coefficients in the industry, MSH10-590HN4G loses just -0.29% of efficiency for every 1.8°F above 77°F.

Quality and reliability

MSH10-590HN4G undergoes various quality checks during the production process and is subjected to serious quality and reliability testing. Manufacturing facilities are highly automated, removing the possibility of human errors. Mission Solar is committed to quality, safety, and dependability to ensure you get the finest.

Low degradation for increased longevity

In the first year of service, these panels will lose no more than 1% of their power output. The average yearly power drop from the second to the 30th year will be no more than 0.4%. After 30 years, the modules will retain more than 87.40% of their initial output.

Certified for the worst environmental conditions

MSH10-590HN4G is PID, salt, acid, and ammonia resistant. It can also bear mechanical loads of up to 5400 Pa on the front and 2400 Pa on the back. This durability is mostly owing to the 1.38" thick anodized aluminum alloy frame and a layer of protective glass.
