2. Increased Accessibility With the rise of solar wholesale, small businesses and contractors can easily access necessary equipment without the barrier of high costs. This democratizes the industry, allowing a more extensive range of installers to participate in the solar market, ultimately leading to greater penetration of solar systems in various regions.
However, advancements in materials and technologies have opened up avenues for exceeding the Shockley-Queisser limit through multi-junction solar cells. These cells stack multiple layers of different semiconductor materials, each with a unique bandgap. By capturing a broader spectrum of sunlight, multi-junction cells can achieve efficiencies of over 45% under concentrated sunlight conditions. This innovation holds great promise for applications in space technology and high-efficiency solar farms.
