Advanced Solar Cell Technology – Half Is More


It’s no doubt that solar energy is a superior choice for servicing practical energy needs. Whether you are powering an industrial setting or a cozy home, you should feel confident in your choice to use solar energy–but even after the choice to go solar is made, how can users enhance their power production to be the most efficient possible?

In this blog, we will discuss the benefits of using solar panels that utilize half-cut cells and how their innovative design is showing the solar world that half is more.

Lower Operating Temperature

Extreme heat is a well-known enemy to electronics. Advanced half-cut cell technology improves solar panel heat production. Split-cells generate less current than full cells. As a result, the generation of excess heat is minimized.

Minimizing heat production reduces the chance of hot spots. Since hot spots occur when part of a solar cell overheats, the performance of the cell is negatively affected as a result.

The ability for a half-cut cell to run cooler means increased performance and longevity of the entire panel.

Shade Resilience

It isn’t uncommon for solar panels to be installed in applications affected by shading. Since a solar panel comprises a cell series that is linked together by an interconnection line, one cell that becomes shaded can affect the performance of every cell within its interconnection series.

Split-cell panels have twice the amount of interconnection lines, allowing for more power production when a solar cell is shaded.

In the case of a traditional full-cell panel, decreased power performance caused by shading is especially prevalent due to fewer lines connecting series of cells. However, in a split-cell panel, the amount of interconnection strings is doubled. This means that if a split-cell panel becomes shaded, fewer cells will be exposed to subsequent energy loss and the integrity of the solar panel is retained.

Less Resistive Loss

In half-cut cell solar panels, the use of three junction boxes reduces internal resistance to increase power output.

Additionally, there is less distance for current to travel in a split-cells. When the distance that current needs to travel is reduced, there is less resistive loss, and power performance is increased.

Solar panels with split cell technology are able to achieve higher power outputs than traditional, full cell solar panels.


It is now clear to see how half-cut cell solar panels are the method of choice when looking to enhance power performance, increase product longevity, and retain the overall integrity of a solar panel.

Increase Bifacial Rear-side Generation With Rail-based Racking

Adopting bifacial solar panels is becoming more prominent in the solar industry. As usage increases, studies reveal that mainstream racking solutions limit bifacial rear-side generation. At Aptos Solar Technology, we assist our customers in maximizing the performance of every bifacial solar panel we produce. In this blog, we will discuss the benefits that come with using a racking system designed specifically for bifacial solar panels.

Traditional Racking Solutions

Mainstream racking solutions are built with monofacial solar panels in mind. Most racking systems are designed with wind deflectors and brackets that run along the back side of the panels, with ballast blocks directly under the panels or between the PVs. This traditional design creates obstructions under the panels, which in turn will cause shadowing that prevents light from reaching the rear-side of the panel.

It is common for racking systems to maintain a low profile, but– for bifacial panels– a higher tilt and clearance with the roof will allow the rear-side of the panel to harvest more energy. While monofacial panels can operate unaffected in these racking conditions, bifacial solar panels can see a serious decrease in rear-side energy production when installed on traditional racking systems.

Keep Both Sides of the Bifacial Panel Exposed to Light

Maximizing the performance of bifacial panels relies on a simple concept: allow both sides of the panel to get as much exposure to light as possible.

Bifacial solar panels perform most efficiently when rail-based racking systems are used. These solutions work by placing rails along the perimeter of the solar panels, leaving the rear-side of the panel exposed to light and free of obstruction. Cables can be tucked along the rails minimizing the shading on the panels.

To get even more energy production from the rear-side of the panel, a racking system that allows to increase the tilt to at least 10° or 15° is preferred. In addition, a racking system that raises the height of the system up to 10″-24″ clearance at the front and that is designed to have larger interrow distance will also increase the bifacial gains.

Generate Up To 30% More Energy

When solar users choose bifacial technology for their panels, they increase their potential for energy generation by up to 30% –making the choice to use an optimized racking system the best investment for users who want to increase energy production and increase the return for their investment.  

Bifacial Solar Technology – The Market is Finally Ready

For years there has been much fascination around bifacial solar technology within the solar industry, and we definitely understand why. There’s no denying that the additional rear side power generation and improved performance in low-light conditions are serious advantages to consider when sourcing solar panels. Higher yield is always a win, right? So why haven’t we seen more bifacial panels deployed? In this blog, we will cover why bifacial technology hasn’t seen its peak and why it’s no longer the technology of the future, but the technology choice for today. 

Performance Advantages

The main attraction around bifacial solar panels is the ability to absorb light from both the front and rear sides of the panel. When installed on highly reflective surfaces (i.e., a light colored roof or white rocks at the base of a ground mount) an increase of up to 30% in yield can be produced from the rear side generation. 

More Bankable Than Ever

Decades of field data has been acquired and bifacial panels are gaining the confidence of solar developers and investors. With new industry standards for bifacial panels released by the International Electrotechnical Commission in 2019, consumers now have a clear common basis for measuring the current-voltage characteristics of bifacial products.

Lower Costs for Bifacial Technology

he stars have finally aligned and the cost of bifacial technology has come down significantly, allowing it to compete in the mainstream solar market. Now that bifacial pricing is comparable with that of monofacial solar panels, projections indicate that bifacial technology will gain a large share of total demand. 

Our customers only pay for the STC front side rated power, yet still get the benefit of rear side power generation. Bifacial modules offer higher power density, resulting in significant balance of system savings and demonstrate higher energy yield — altogether giving consumers the best levelized cost of energy(LCOE).

Not Your Average Bifacial Panel

Our team of product engineers has stacked advanced solar technologies to maximize the power performance of our bifacial panels. Because our panels utilizes half-cut cells, our bifacial panels absorb 3% more light than conventional bifacial panels.
