Silfab Solar Panels Technology

Silfab has introduced a few small tweaks in the photovoltaic (PV) panel scene, but most of the tech they use in their panels nowadays is standard across different companies. In the next sections, we’ll discuss the details of the technology Silfab incorporates into its products.

Half-Cut Solar Cells

This is a widely adopted technology in tier-one panels used by most solar panel manufacturers. Half-cut solar cells are smaller than the standard ones, allowing more cells to be accommodated in a single panel. As a result, the increased cell count enhances the energy production capabilities of Silfab panels.

Additionally, panels with half-cut cells often have two independently functioning halves, enhancing power generation in areas with partial shading.

9-Busbar Technology

Busbars play a crucial role in Silfab Solar panels by conducting electricity across the solar cells. In general, the more busbars there are, the lower the resistance inside the cell. It leads to increased power production and conversion into usable electricity. The estimate for the increase in power production in a 9-busbar panel over a 5-busbar panel is around 25%.

Silfab Solar panels incorporate 9-busbar (9BB) technology. However, this technology is not unique to Silfab and is commonly employed by most tier-one manufacturers, including direct competitors like REC and QCells.

PERC Cells

The acronym stands for passivated emitter and rear contact cells. Monocrystalline cells with such a technology represent some of the most advanced solar cells used by tier-one panel manufacturers.

PERC cells offer two key advantages over conventional cells:

  1. Firstly, they can capture solar energy that would otherwise escape through the back of the panel, enhancing overall energy production.
  2. The placement of contacts on the back sheet of the panels minimizes the amount of energy blocked at the front. As a result, solar PV installers can save time and reduce costs when using the PERC standard, as fewer panels are needed to achieve the same solar power output.

While this technology doesn’t necessarily distinguish Silfab panels from their competitors, it positions the company as one of the top players in the nation’s solar industry.

Silfab Solar Panels Price

Silfab Solar panels for sale cost between $0.69 and $0.79 per watt before installation. Specifically for residential use, a single Silfab Prime module may cost around $278, while the more upscale Elite model has a slightly higher price of $315. However, actual Silfab solar panel prices can fluctuate based on your system’s size and the required panels.

Considering the features and high quality provided, Silfab Solar panels offer good value for such an investment. Regarding total installed system expenses, homeowners can anticipate costs ranging from $2.75 to $3.25 per watt of installed system capacity. Consequently, an average 6-kilowatt (kW) system might amount to approximately $15,000 to $20,000.

A few other aspects are influencing Silfab Solar panels price:

  • The installer
  • The number of panels
  • Additional components (inverters and batteries)

However, residential users can take advantage of incentives such as the federal solar tax credit that substantially reduces the overall cost of their solar system.

Peculiarities of the Silfab Warranty

Many solar panel manufacturers provide an equipment warranty that covers defects and related damages, along with a performance warranty ensuring a minimum production level. Silfab offers both options, and its production warranty stands out as one of the longest in the industry.

Silfab’s warranty on equipment is standard: it includes a 25-year performance guarantee (a typical duration in the American market) and covers common defects. It works if you choose an authorized installer. However, the efficiency warranty extends to 30 years, surpassing the industry standard of 20 years by about 50%.

While Silfab’s efficient warranty duration is impressive, it’s crucial to consider the guaranteed performance at the end of the warranty goes downhill. In this aspect, Silfab solar panel warranty falls below average. They guarantee that their panels will only lose 2.9% of their initial efficiency in the first year, surpassing competitors who promise no more than 2.5% and industry leader Trina, which guarantees just 1%.

25 years 30 years 2.9 %

In a nutshell, Silfab solar panels boast a lifespan of 25 to 35 years. Not only does the Silfab warranty offer excellent longevity, but it also allows for substantial net savings on electric bills over time.
