Photovoltaics (PV) involves direct processing of the solar radiation into the electricity in the cell build on the basis of silicon. A single cell produces up to 2 W of electricity. In order to reach higher voltage and power, the individual cells are combined adequately in series or in parallel. This is the way of building photovoltaic panels. Photovoltaic devices has durability, simplicity of construction and maintenance. The advantage of photovoltaic cells is that they can be built as an independent systems of power from a few microwatts to megawatts. It allows to use cells in all conditions, for example, in agricultural wasteland, post-industrial areas. The equipment can be as well integrated with the architectural objects (such as roofs, facades of buildings). Photovoltaic panels are environmentally safe, do not emit any noise or pollution.

Examples of the use of photovoltaics:

• billboards, road signs,
• emergency power supply systems,
• machine of small-scale trading (eg parking meters, beverage machines),
• environmental monitoring equipment,
• powering of boats, camping trailers,
• remote places of power (such as shelters, water pumping stations, telephone relays),
• small local solar power stations and solar power farms such as solar panels on buildings.

Each application of photovoltaic devices is an individual process. Therefore, it is recommended to implement it from the basic concept and design.
