Solar thermal installation. Concrete example of saving with the installation of a system of only 4 square meters of thermal panels
A family of four can meet in a year at least two-thirds of its hot water needs installing on the roof about 4 square meters of solar thermal panels. Solar thermal systems, due to technological developments, today extremely durable, resistant and reliable and help to increase the value of the property. The savings, as well as depend on the climatic conditions of the place, is related to the cost of replaced energy and varies according to the source of energy used (electricity, natural gas, oil, coal) and the price of fuel.
Economical Benefits
A solar thermal system installed in a workmanlike manner can last even 30 years while maintenance costs are about 70 euro a year.
The initial investment can pay off in a few years (5-8 years in energy prices constant). The payback time depends on many factors such as:
Latitude as in the south as there is a greater radiation, serve a smaller amount of solar collectors;
Exposure to the sun: the presence of any obstacles that reduce insolation also reduces the profitability of the plant;
Technology (type of solar collector installed);
forecast on the increase in energy costs;
Environmental Benefits
From the environmental point of view saves the environment up to 4000 Kg of CO2 and in some cases, up to 60% of the consumption of gas or electricity reaching an average savings that can reach 700 € in the bill.
