Solar Power - Technology

Solar Power is an inexhaustible source continuously generated by the Sun's internal nuclear reactions. This incredible quantity of power reaches our planet as electromagnetic radiations that move in the air and reach the ground. This energy is estimated to exceed by 15,000 times the world's needs.

In Italy, for instance, the daily average radiation over the course of one year goes from 3.6 kWh per square metre in the Po Valley to 5.4 kWh per square metre in Sicily. Practically, only an irradiated surface of less than 2 square meters in Central Italy could produce enough solar energy to meet the yearly needs of an average household (around 3,000 kWh).

A considerable portion of this energy can be used by photovoltaic or solar thermal plants to produce electricity or hot water.

Solar Thermal Plants
They use solar radiation to produce heat. The main use is low temperature hot water production (up to 80°C) for sanitary purposes and to heat private houses.
In countries with a high solar radiation, electricity can also be produced, in facilities that work with high temperatures and more sophisticated technologies and are large enough to reach the capacity of an electric power plant.
Italy, with its 500 thousand square meters of solar thermal panels, is still far from the performance achieved by European neighbours, like Germany, which produces over 6.5 million square metres or Greece, 3 million.

Photovoltaic systems
They convert solar radiation into electricity by exploiting the properties of semiconducting materials such as silicon, suitably treated to generate electricity when the sunlight reaches them. The produced energy can be stored in batteries, so that it can always be available, or it can be grid-connected and used immediately.
