Solar panels are those devices which are used to absorb the sun’s rays and convert them into electricity. A solar panel is actually a collection of solar (or photovoltaic) cells, which can be used to generate electricity through photovoltaic effect. These cells are arranged in a grid-like pattern on the surface of solar panels. Once Client has paid for its initial installation costs, the electricity it produces for the remainder of the solar panel lifespan, which could be as much as 15-20 years depending on the quality of the system, is absolutely free! Most solar panels are made up using crystalline silicon solar cells. Power & Solar Systems Limited offers a range of top-notch Yingli solar panels. By connecting these with our inverters, solar controllers and batteries, you can become totally self-sufficient, energy-wise.
