Photovoltaic
panels
The first PV panels were installed in 1997. Panels
with a capacity of 10 kW, together with a Power Conditioning Subsystem
that functions as a DC-AC converter and grid-connect with the diesel
generator were installed. The grid connection with the diesel generator
started in April 1998. More PV panels were installed every year after
that. Installation was complete in the 2001/2002 season. Presently,
there is PV capacity of 55 kW. The PV panels head north,
60°east and 60°west from true north. This array has
been adopted because the total electricity obtained is more and the
cost is lower than north-direction array of 50kW p anels. The annual
total energy produced is about 44,000 kWh (annual mean is 5 kW), which
corresponds to about 3% of total electric generation at Syowa Station.
Solar
wall
Air- type solar collectors for warming the inside of
building were installed on the north and east sides' wall panels of a
workshop in 2001. The solar collector consists of an intake fan that is
powered by a 22W PV and a collector panel of 1.1 m2. The energy
obtained from the system is estimated as 86,318 MJ per year.
Solar
collector
A solar collector with evacuated glass tubes was
introduced to rise the water temperature in the tank of the summer
accommodation lodge. The capacity of the system is 324,000 kcal per
day, that could rise the water temperature from zero to 30 ?. The warm
water is boosted by a hot water boiler and used for heating rooms.
