About product

SIL-410-BG is part of the SILFAB ELITE Series — one of the most recent made by Silfab. These panels employ cutting-edge technologies to achieve superior efficiency and reliability. 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. 

Silfab employs full-sized solar cells for this model. As a result, the panel achieves an impressive efficiency of 21.4%. Novel design solutions allow this panel to look as well as it performs. This model is just 1.4" in depth and is jet black with a sleek finish. The panel's functionality and durability are not affected by its aesthetic appeal though. Silfab paid as much attention to durability as they did to performance. SIL-410-BG is guaranteed to retain at least 82.6% of output after 30 years. Product warranty for this panel lasts 25 years. 

  • 410 W power output
  • 66 full-sized PERC cells
  • 21.4% efficiency
  • 1000 V DC maximum system voltage
  • MC4 connectors
  • 25-year product and 30-year performance warranties

Increased efficiency of up to 21.4 percent

SIL-410-BG ensures maximum power production. The combination of PERC technology and a powerful antireflective coating results in 21.4 percent module efficiency. This is much greater than the average, resulting in significant extra savings over the years of production.

Keeping cool in hot weather

Even at high temperatures, SIL-410-BG remains efficient. It loses just 0.279% efficiency for every 1.8°F over 77°F, letting you make the most of the sunniest hours.

High quality standards

Silfab stringent production requirements include various tests to guarantee high quality. The facilities are highly automated, allowing the manufacturer to maintain high standards while keeping warranty claims to a minimum.

Reliability and degradation resistance

Slow degradation over the next 30 years is guaranteed by Silfab. The performance will decrease no more than 2% during the first year and 0.25% annually thereafter. Your modules will retain at least 82.6% of original performance after the 30 years are over. This 410 W Silfab solar panel also comes with a generous 25-year product warranty.

Certified for the most extreme environmental conditions

PID, salt, acid and ammonia cannot harm SIL-410-BG. Furthermore, it has a mechanical load resistance of up to 5400 Pa in the front and 4000 Pa in the back. A layer of protective glass and 1.4" thick anodized aluminum frame are the primary reasons for its toughness.

Outstanding all-black design

The panel has a sleek, all-black style that complements any roof beautifully. Silfab uses unique treatment and selection procedures to guarantee optimum cell color. The cells are connected by thinner wires, and from a distance, the surface of the modules seems seamless and smooth.

A panel like you've never seen before - in a good way. Obsidian-black surface, interesting cell layout, super thin. A piece of art

One of the reasons I like A1 so much is that they sell so many American-made products. This superb Silfab panel is no exception. I would even go as far as saying that this model is the most technologically advanced of all made on the US territory

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
