Customer ServicePhotovoltaic systems are continually evolving to improve their efficiency and financial viability. One trend is to move to larger strings of cells giving higher dc voltages to be converted to ac voltage for the grid. Cost savings result but auxiliary power supplies for monitoring and control need to accept these higher voltages as inputs.
There may be a need for an auxiliary power supply for various equipment, such as monitoring, SCADA, safety, lighting, air conditioning, etc, in the case of large solar power systems. To increase their effectiveness and commercial viability, photovoltaic systems are always being improved.
Cost savings result but auxiliary power supplies for monitoring and control need to accept these higher voltages as inputs. Photovoltaic (PV) power generation systems have always fought to justify themselves in terms of $/watt of generated power and are hampered by the initial low efficiency of the panels themselves.
One development is the use of long strings of cells, which provide higher DC voltages that can be used to generate AC voltage for the grid. Auxiliary power supply for monitoring and control must accept these higher voltages as inputs in order to avoid incurring additional costs. Must Read: Solar Power per Square Meter Calculator
