What are the disadvantages of a photovoltaic (PV) system?
Initial Cost –PV systems are initially expensive. –To offset the high initial cost, some adjustments are necessary in home appliance selection. Reliance on the weather –PV systems require sunlight, which may not be available for stretches of time because of cloudiness. Energy Storage –PV systems usually require batteries to store energy for use when the sun is down. Batteries are bulky and increase the system’s size and complexity.
