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

Among the newest offerings of Silfab, SIL-440 QD DCA4 is part of the Silfab Prime NTC series. These panels use state-of-the-art technology to achieve high efficiency and dependability. This panel 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. As a result, the panel achieves an impressive efficiency of 22.6%.

Cell surface, back foil, and frame are completely black, giving the model unrivaled aesthetics. Silfab paid as much attention to durability as they did to performance. SIL-440 QD DCA4 is guaranteed to retain at least 89.30% of output after 30 years. The module product workmanship warranty for this panel lasts 25 years.

  • 108 half-cut N-Type cells
  • 440 W nameplate capacity
  • 22.6% efficiency
  • 1000 V DC maximum system voltage
  • MC4 from Staubli connectors
  • 25 years of module product workmanship warranty and 30 years of linear power performance guarantee

Increased efficiency of up to 22.6%

SIL-440 QD DCA4 ensures maximum power production. 22.6 percent module efficiency is achieved using N-Type cell technology and a powerful antireflective coating. This is much greater than the norm, resulting in significant additional savings throughout the years of operation.

Heat-resistant performance

This module makes the heat less dangerous since it has one of the lowest temperature coefficients in the market, losing just -0.29% of efficiency for every 1.8°F over 77°F.

Quality and reliability

SIL-440 QD DCA4 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, Silfab is committed to quality, safety, and dependability.

Reliability and degradation resistance

Silfab guarantees slow deterioration over the next 30 years. The performance will decline by no more than 2% during the first year and then by no more than 0.3% every year after that. After 30 years, your modules will retain at least 89.30% of their original performance. This 440 W Silfab solar panel also comes with a substantial 25-year module product workmanship warranty.

Enhanced frame design

This model's construction makes it perfect for both residential and business rooftops. Durability and strength are increased by using a robust, black-anodised aluminium frame. The model may support a significant snow load of up to 5400 Pa. The panel's back can support 4000 Pa, assuring that even the strongest winds won't damage your system.

Outstanding all-black design

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