About product

Among the newest offerings of Silfab, SIL-400 HC is part of the SILFAB PRIME series. These panels use state-of-the-art technology to achieve high efficiency and dependability. The Passivated Emitter Rear Contact (PERC) technology ensures excellent power output. This solar cell type employs an additional reflective layer to absorb more sunlight. 


Another advantage is the half-cut cell technology. SIL-400 HC 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 20.2% — 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. 

  • 400 W power output
  • 132 half-cut PERC cells
  • 20.2% efficiency
  • 1000 V DC maximum system voltage
  • MC4 connectors
  • 25-year product and 30-year performance warranties

Outstanding productivity integrating the newest advances

This panel's manufacturer offers power output of 400 W at 20.2 percent efficiency. High energy production levels are attained by utilizing the most recent developments in the solar sector. A more productive panel produces more per square foot and pays for itself more quickly.


Keeping the cool in high temperatures

SIL-400 HC manages to stay efficient even at high temperatures. For every 1.8°F above 77°F, it loses just 0.28% in efficiency, allowing you to make the most of the sunniest hours.

Quality and reliability

SIL-400 HC 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 increased longevity

In the first year of service, these panels will lose no more than 2.9% of their power output. The average yearly power drop from the second to the 30th year will be no more than 0.50%. After 30 years, the modules will retain more than 82.6% of their initial output.

A panel that can handle hail, wind and snow

The 1.37" frame made from anodized aluminum and a layer of protective tempered glass make this module resistant to the foulest of weather. The front side of the modules can resist a 5400 Pa load, and the back side 4000 Pa.

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.

We recently purchased these panels for our home and couldn't be happier with the performance. As someone who cares deeply about the environment, I think going solar was a step long overdue. Installation was a breeze and now the panels are generating even more energy than we expected. Overall, I would highly recommend Silfab to anyone looking for a reliable and efficient solar panel for their home.

Hi, I'm John, a tech enthusiast and homeowner. We recently bought these Silfab 400W panels, and I have to say I'm pretty impressed. As someone who's into cutting-edge technology, I was drawn to the high efficiency and advanced PERC technology, which I can tell the panels are delivering on the promises even on partly cloudy days. The panel's sleek black design was also a plus, and it blended in nicely with the aesthetics of our home. Highly recommended!

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
