Hamburg/München (ots) - Effective light in solar plants

The energy in solar plants, particularly in isolated solutions
(SHS - SolarHomeSystems) is precious, because only limits available!
Therefore if possible little energy should be applied for light
production. The first step exists in the correct shining means. In 12
V-plants present themselves for it:

1) Compact fluorescent lamps CFL and CCFL lamps
2) Light emitting diode lamps (LED)
Both have their specific authorisation, CFL as room lighting,
similarly as the employment of bulbs and light emitting diode
lamps as spots for object lighting and for reading.

CFL lamps are electronically expressed wash and wear apart from
their long starting procedure, because they can deal with the voltage
fluctuations arising in SHS problem-free.

The life span of LED lamps however depends strongly on the correct
voltage and warmth. Therefore on the commercial lamps you will find
regulating electronics, which cushions voltage peaks. This
electronics is large-scale, wastes energy, produces warmth and is
expensive. A central, unique regulation of constant voltage can save
20% of the produced energy. The idea is simple, because the
overvoltage is not burned, but is intelligently regulated. The
automatic controller infers in other words only the energy quantity
from the battery, which is concretely used and sends this to the
consumer.

This way 11.6 KW/h energy (or 7 kg CO2) can be saved in a 80 W
PV-system with 105 Ah battery and 40 W light energy. With this
computation the lamps "are on "4 hours on the day. With a production
price of Euro 0.30 per KW/h means this per year a saving of Euro
10.61, if one refers the longer life span of the lamps due to the
automatic controller also. The initial costs of the lamps including
the automatic controller refers to one period of 5 years.

The next step is the off grid supply of a complete village. Unused
resources from the individual SHS plants are seized together and made
available to communal facilities such as hospitals or mobile phone
stations.

will receive all further information and consultation to light in
solar plants.
