The Advantages And Disadvantages Of Using Photo Voltaic Panels

Solar photo voltaic panels which are commonly known as the solar pv panels are the best way to gather solar energies. These panels actually help to preserve solar energy in an hour to a certain amount which can provide the necessity of solar electricity for a year.


Before using Solar PV Panels, an individual should be aware of the advantages and disadvantages it has.


There are various advantages of using Solar PV Panels.


  • Solar energy is energy supplied by nature – it is thus free and abundant!
  • PV panels provide clean – green energy. During electricity generation with PV panels there is no harmful greenhouse gas emissions thus solar PV is environmentally friendly.
  • Solar energy is especially appropriate for smart energy networks with distributed power generation – DPG is indeed the next generation power network structure!
  • Solar energy can be made available almost anywhere there is sunlight
  • Photovoltaic panels, through photoelectric phenomenon, produce electricity in a direct electricity generation way
  • Operating and maintenance costs for PV panels are considered to be low, almost negligible, compared to costs of other renewable energy systems
  • Solar Panels cost is currently on a fast reducing track and is expected to continue reducing for the next years – consequently solar PV panels has indeed a highly promising future both for economical viability and environmental sustainability.
  • PV panels are totally silent, producing no noise at all; consequently, they are a perfect solution for urban areas and for residential applications because solar energy coincides with energy needs for cooling PV panels can provide an effective solution to energy demand peaks – especially in hot summer months where energy demand is high.
  • PV panels have no mechanically moving parts, except in cases of –sun-tracking mechanical bases; consequently they have far less breakages or require less maintenance than other renewable energy systems.
  • Residential solar panels are easy to install on rooftops or on the ground without any interference to residential lifestyle.
  • Though solar energy panels’ prices have seen a drastic reduction in the past years, and are still falling, nonetheless, solar photovoltaic panels are one of major renewable energy systems that are promoted through government subsidy funding (FITs, tax credits etc.); thus financial incentive for PV panels make solar energy panels an attractive investment alternative.

These Solar PV Panels have a few disadvantages too.


  • Consequently, intermittency and unpredictability of solar energy makes solar energy panels less reliable a solution.
  • For a continuous supply of electric power, especially for on-grid connections, Photovoltaic panels require not only Inverters but also storage batteries; thus increasing the investment cost for PV panels considerably
  • As in all renewable energy sources, solar energy has intermittency issues; not shining at night but also during daytime there may be cloudy or rainy weather.

In case of land-mounted PV panel installations, they require relatively large areas for deployment; usually the land space is committed for this purpose for a time period of 15 to 20 years or may be longer.
