A rooftop solar power system, or rooftop PV system, is a photovoltaic (PV) system that has its electricity -generating solar panels mounted on the rooftop of a residential or commercial building or structure.
How Rooftop Solar Systems Work At the heart of a rooftop solar system are solar panels, which are designed to capture sunlight and convert it into electricity. These panels consist of photovoltaic cells, typically made of silicon, which generate a flow of electricity when exposed to sunlight.
Most rooftop solar panel cells are called photovoltaic cells which are also found in tiny appliances like calculators. The most important components of a photovoltaic cell are the layers of the semiconductor materials that are made of doped silicon crystals.
Most rooftop PV stations are Grid-connected photovoltaic power systems. Rooftop PV systems on residential buildings typically feature a capacity of about 5–20 kilowatts (kW), while those mounted on commercial buildings often reach 100 kilowatts to 1 megawatt (MW). Very large roofs can house industrial scale PV systems in the range of 1–10 MW.
One of the primary advantages of rooftop solar systems is their ability to generate clean and renewable energy directly at the point of consumption. By utilizing available rooftop space, these systems reduce dependence on traditional grid-based electricity, mitigating the environmental impact associated with fossil fuel-based power generation.
As of May 2017, installation of a rooftop solar system costs an average of $20,000. In the past, it had been more expensive. Utility Dive wrote, "For most people, adding a solar system on top of other bills and priorities is a luxury" and "rooftop solar companies by and large cater to the wealthier portions of the American population."
