PV panels require minimal maintenance and service during their useful life, which can be 25 years or more. Regular maintenance includes periodic cleaning of PV panels to remove dust, leaves or other particles that could affect their efficiency. Also, regular checking and maintenance of ancillary equipment such as the inverter and cabling system may be necessary to ensure optimal operation of the whole system.

Installing photovoltaic panels can be influenced by many factors, including:
1)Location orientation: It is important to have enough available space and proper orientation to the sun to maximize the efficiency of the solar system.
2)Local regulations and permits: Local rules and regulations as well as obtaining building and grid connection permits can influence the installation process.
3)Condition of roof or mounting surface: Roofs or other mounting surfaces must be structurally sound and able to support the weight of the PV panels.
4)Local meteorological conditions: Factors such as the amount of available sunlight and the local climate can influence the potential for solar energy production.
5)Financing and available budget: The cost and availability of financing can affect the size and complexity of the solar system installed.

Photovoltaic panels consist mainly of solar cells, which are usually made of crystalline silicon or other semiconductor materials. These cells are integrated into a supporting structure and protected by a layer of glass or transparent plastic, which allows sunlight to pass through and protects the cells against weathering and damage. Photovoltaic panels may also include an anti-reflective layer to improve the absorption of sunlight and a layer of hydrophobic material to prevent the accumulation of dust and dirt.
