About product

SS-M-390-B is a high-performance solar module made by Sonali. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight.

To further boost the performance, Sonali employs half-cut cell technology. Each of the panel’s 108 cells is only half the size of a traditional solar cell. This grants SS-M-390 lower resistive losses and better shade tolerance. At 20.19% efficiency, SS-M-390-B offers surprising performance for its weight and size. Cell surface, back foil and frame are completely black, giving the model unrivaled aesthetics. Sonali provides an industry-leading 25-year performance warranty and a 25-year product warranty.

  • 390 W power output
  • 108 half-cut PERC cells
  • 20.19% efficiency
  • 1500 V DC maximum system voltage
  • MC4-compatible connectors
  • 25-year product and 25-year performance warranties

Higher efficiency of up to 20.19%

The highest power output is guaranteed by Sonali SS-M-390-B with an efficiency of up to 20.19%. Such outstanding performance is the product of PERC technology and an effective antireflective coating. This is notably above average, which will translate into significant additional savings over the course of operation.

Improved efficiency at high temperatures

Greater energy as temperature rises is a mark of a good temperature coefficient. Your panel's efficiency will drop by just -0.37% for every 1.8°F increase over 77°F.

Quality and reliability

SS-M-390-B 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. Sonali 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 2% of their power output. The average yearly power drop from the second to the 25th year will be no more than 0.55%. After 25 years, the modules will retain more than 84.8% of their initial output.

Certified for the most extreme environmental conditions

PID, salt, acid and ammonia cannot harm SS-M-390-B. Furthermore, it has a mechanical load resistance of up to 5400 Pa in the front and 3600 Pa in the back. A layer of protective glass and 1.38" thick anodized aluminum frame are the primary reasons for its toughness.

Outstanding all-black design

The panel features all-black design which looks great on any roof. The manufacturer ensures excellent cell color by special treatment and selection processes. Sonali engineers use thinner wires to connect the cells together, and at a distance the surface of the modules appears smooth and uninterrupted.

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%.
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
