What are the advantages of a photovoltaic (PV) system?
Reliability –Uninterrupted Power Supply (UPS). In effect, no blackouts due to power failures Durability –PV modules typically last 25 years. –Good batteries last 10 to 15 years. Low maintenance –Panels have to be cleaned once a month. –Battery water has to be checked once a month and replenished if necessary. –Batteries have to be “equalized” or charged up every ten weeks to three months. No fuel cost –No monthly bills. –No purchase, storage, or transportation costs for fuel. No Sound Pollution –PV systems operate silently. Safety –PV systems use no combustible fuels and are safe if properly designed and installed. Independence –PV systems allow users to live even in remote regions. –City dwellers gain independence from the grid.
