Photovoltaic panel components can be made in different shapes, and the components can be connected to generate more electricity. In recent years, photovoltaic panels can be used on roofs and building surfaces, even as part of windows, skylights or shading devices. These photovoltaic facilities are usually called photovoltaic systems attached to buildings.

A photovoltaic panel module is a device that generates direct current when exposed to sunlight. Solar energy is composed of solid photovoltaic cells made almost entirely of semiconductor materials (such as silicon). Since there are no active parts, it can be operated for a long time without causing any loss. Simple photovoltaic cells can provide energy for watches and computers, and more complex photovoltaic systems can provide lighting for houses, traffic lights and monitoring systems, which are integrated into the grid. Photovoltaic panel components can be made in different shapes, and the components can be connected to generate more electricity. In recent years, photovoltaic panels can be used on roofs and building surfaces, even as part of windows, skylights or shading devices. These photovoltaic facilities are usually called photovoltaic systems attached to buildings. According to the survey, due to overcapacity, the profits of the world's five largest manufacturers have shrunk, and the installation of photovoltaic modules will decrease in 2012, the first decline in more than 10 years. According to Bloomberg's average forecast of six analysts, households and commercial organizations around the world will install 24.8GW of photovoltaic modules. This is equivalent to the power generation of about 20 nuclear reactors, but it is 10% lower than the 27.7GW of new PV installed capacity last year. Bloomberg New Energy Finance estimates that annual installations have increased by 61% since 1999.
