| Profitability
The
profitability of solar thermal plants is heavily dependent
on the trends of heating oil prices. These are currently at
a historic high of 60 Dollars per barrel (last updated 7/2005).
Recent
forecasts by a US investment bank predict and explosion in
the price of heating oil over the next few years, even at
an annual rise of 10 percent (comparable with the period 1999
to 2005) the use of solar thermal technology will become increasingly
viable. In view of the shrinking oil and gas reserves, the
decentralized production of solar heat represents a wise investment
for the future.
Solar
thermal systems have a minimum life of 20 years. Little maintenance
is required.
A
collector surface area of 10 qm and a storage volume of 500
liters is sufficient to supply a household of 4 persons with
hot water and supplementary heating. |
