About product

Silfab SIL-520 is a PV module fit for both residential and commercial applications. Silfab engineers made the QM 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. SIL-520 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. The efficiency of this model reaches 21.9% — well above the market’s average. The innovations made the appearance of the panel as impressive as the specs. A mere 1.37" thick, this model is completely black with a smooth surface. This beauty doesn’t compromise the quality or reliability of the panel. Silfab provides a 25-year product warranty. Stable power output is also guaranteed — performance warranty will protect you during 30 years.

  • 120 half-cut PERC cells
  • 520 W nameplate capacity
  • 21.9% efficiency
  • 1000 V DC maximum system voltage
  • Staubli EVO2 connectors
  • 25 years of product and 30 years of performance warranty

Increased efficiency of up to 21.9 percent

SIL-520 ensures maximum power production. The combination of PERC technology and a powerful antireflective coating results in 21.9 percent module efficiency. This is much greater than the average, resulting in significant extra savings over the years of production.

Excellent performance in adverse weather

Low temperature coefficient means greater energy production at high operating temperatures. SIL-520 loses just -0.29% of efficiency for every 1.8°F above 77°F.

Quality and reliability

SIL-520 is subject to rigorous quality and reliability testing as well as many quality checks throughout the production process. The level of automation in the manufacturing facilities virtually eliminates human error. To guarantee that you receive the finest, REC is committed to quality, safety and dependability.

Low degradation for a longer lifespan

These panels will lose no more than 2% of their power output in the first year of service. From the 2nd year to the 30th year, the average annual power decline will be no more than 0.54%. The module retains over 82.34% of its original output after 30 years. Guaranteed by Silfab.

A panel that can handle hail, wind and snow

The 1.37" frame built of anodized aluminum and a layer of protective tempered glass make this module weather-resistant. The front side of the modules can withstand a 5400 Pa load, whereas the back side can withstand a 2400 Pa load.

Stunning black aesthetics

The sleek, all-black aesthetics of the panel will complement any rooftop. By using a variety of treatments and selection criteria, the producer guarantees high quality cell color. Engineers at Silfab employ smaller gauge wires to link the cells together, creating a seamless appearance.

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
