Most photovoltaic power plant stations are on the ground. However, some large ones are on rooftops. A photovoltaic grid on a rooftop such as a large warehouse is big enough to deliver electric power to many customers. Several small rooftop systems can be combined and provide electrical power equivalent to a large scale installation.
Photovoltaic power plant in the UK
Part of an EU agreement is to produce 15 percent of all energy from renewable sources by 2020. As a result, thousands of photovoltaic power plant systems sprang up in 2010. The Photovoltaic power plant systems are in operation on roofs of businesses, convention centers and governmental buildings. The Newark-on-Trent in Nottinghamshire completed the United Kingdom’s largest photovoltaic power plant system in July 2011. Construction took a mere seven weeks. This solar panel system is expected to contribute around 4,860 MW-hours of electricity yearly. The electricity will become part of the national power grid in the UK.
A photovoltaic grid can be built into a wall, the roof of a newly constructed building or into existing buildings. They are used in grazing and farming operations. Advances in the manufacturing process and in technology continues to move the cost of solar cells down. Solar cells are the fastest-growing renewable energy technology in the world. A photovoltaic grid can coordinate and stay aligned with the sun’s path through the sky. This improvement creates more electricity than PV systems that cannot track the sun. The power stations are efficient and cost effective. They don’t produce harmful emissions or fuel costs.
