One of the key ways in which solar panel technology has evolved is increased efficiency. Solar panels have become more efficient at converting sunlight into electricity, with some of the highest efficiency panels on the market today reaching almost 23% efficiency. In fact, researchers at the National Renewable Energy Laboratory (NREL) have even created a solar cell with a record-breaking 39.5% efficiency.
Another major improvement in solar panel technology over the past decade has been a reduction in cost. Solar panel prices have decreased significantly, making them more affordable for consumers. This has been achieved through advances in manufacturing processes and the use of cheaper materials.
How does Solar Energy Work?
Solar panels have also become more durable and reliable over the past decade. Many modern solar panels come with warranties of 25 years or more, and some have even been known to last for 40 years or more. In addition to increased durability, manufacturers have also begun to explore new materials and technologies that can improve the efficiency and performance of solar panels. For example, thin-film solar cells made from materials such as copper indium gallium selenide (CIGS) or cadmium telluride (CdTe) are being experimented with by some companies.
Finally, solar panels have become more aesthetically pleasing, with many manufacturers offering panels that are designed to blend in with the roofs of houses. This has helped to make solar panels more appealing to homeowners.
Overall, the past decade has seen significant advancements in solar panel technology, making it a more efficient, cost-effective, durable, and visually appealing option for generating electricity.
