The solar power industry is seeing a shift in a few different things when it comes to solar panels. We are seeing more and more solar companies increasing the size of the photovoltaic cells, as well as using the half-cut solar cell technology. But another trend that we saw at SPI 2019 was an industry-wide shift to all-black solar panels.
There are a few reasons that homeowners are leaning towards getting all-black solar panel installations on their rooftops.
All Black Solar Panels - The Technology
The super black photovoltaic cells are so special because the solar panels are able to absorb 99.7% of sunlight. This means that only 0.3% of incident light is reflected from the photovoltaic cells surface, which helps it beat the typical anti-reflective coating in the more traditional technology of solar panels.
The black photovoltaic cells use more sophisticated nanotechnology in the production process.
The nanotechnology has been gaining momentum in more recent years. The nanotechnology is a science, engineering, and technology developed at the nanoscale, which is around 1 to 100 nanometers. The application is being used to redesign everything we know from medicine to car parts and now is being used for solar panels.
This nanotechnology has opened a whole new realm on the way that things are designed. This new nanotechnology has helped increase the efficiency of a solar panel.
As everything is done on the nanoscale, the geometry of the nanotexture can vary. Small changes in the nanoscale are going to have a large impact on the macroscale. Therefore the different solar companies that are manufacturing a new generation of solar panels are using different approaches to their nano designs.
As the different layers of the photovoltaic cells are so small, the lighter wavelength sees the cell as a single structure. Hence, the reflection is small. The efficiency of a solar panel is reported to have around a 0.4% increase using the nanotechnology approach to develop the all-black photovoltaic cells.
For the new process, the efficiency of a solar panel is a major leap in the right direction. The reason being, darkness is the absence of light and the all-black color illustrates the ability to absorb the majority, if not all of the light.
This technology has taken quite some time to develop the technology as the industry has had to overcome quite a few technological challenges. One of the major challenges was keeping the nanostructure intact during the silicon doping process. Doping is an extremely important part of the manufacturing of photovoltaic cells, it involves the adding of impurities to intrinsic semiconductors in order to alter their properties at high heat.
Another huge impact that all black solar panels have when it comes to all-black solar panels is the aesthetics. Homeowners are gearing towards all-black solar panel installations due to their sleek all-black appearance. These solar panels look good on any and every rooftop and they are proving to be some of the most efficient panels on the market today.
The All Black Solar Panels on the Market
Hanwha Q Cells, q-peak duo blk-g6 all-black solar panels, come with a 25-year warranty and are expected to raise the efficiency of a solar panel to up to 20.1%. The new G6 Module has 340 W power output and is certified to handle heavy snow and wind loads. The solar panels will have larger photovoltaic cells that will help the panels deliver up to 6% more solar power
LONGi released its hi-mo4 module that uses m6 size, 166-millimeter wafers, which is larger than previous modules. The new solar module boasts a maximum power output of 345 watts and a solar panel efficiency of 18.3%. The new module has a better energy yield with a low irradiance performance coefficient and less than 2% first-year power degradation.
The HiDM all-black solar panels from Canadian Solar have a better shading tolerance in comparison with their other panels. With a lower internal current, lower hot spot temperature, reduced risk of solar cells cracking in a small region and the solar panel enhances the module reliability. They can also withstand heavy snow loads and strong wind powers. The HiDM has a 330 W power output with the efficiency of a solar panel tp 19.57%.
Solaria Power XT solar modules have a sleek all-black look. The solar panels have a 360 W power output raising the company’s solar panel efficiency to 19.9%. Solaria’s modules are one of the highest power modules on the market, producing more power per square meter area, and they lower the installation costs due to fewer BOS components.
