Investing in a photovoltaic system<\/strong> is certainly a wise decision: it avoids the combustion of fossil fuels and helps to reduce the consumption of electricity. However, the introduction of this additional energy supply leads to a change in the electrical features of the system.<\/p>\n\n\n\n

The main critical issues are:<\/p>\n\n\n\n

• decrease in the cos<\/strong>\u03c6<\/strong> on the distributor side, due to the lower active power supplied (supplied by the photovoltaic), keeping the reactive power constant;<\/li><\/ul>\n\n\n\n
  • the addition of on-site exchange photovoltaics makes the existing power factor correction insufficient<\/strong>, in terms of capacitive reactive power on board;<\/li><\/ul>\n\n\n\n
    • by increasing the quantity of kvar installed, the ratio between the power factor correction and the apparent power of the MV \/ LV transformer changes and it is therefore necessary to re-check the risk of resonance<\/strong>;<\/li><\/ul>\n\n\n\n
      • on days with scattered clouds but clear skies, the PV system provides a very variable instantaneous power<\/strong>, with a high number of PFC equipment operations (= wear of the contactors) to ensure the correct cos\u03c6.<\/li><\/ul>\n\n\n\n

        Unfortunately, many companies do not take these factors into consideration and are unaware that the installation of a PV system worsens the power factor<\/strong>.<\/p>\n\n\n\n
