It would be a good investment replace old Eternit roofs houses with
solar panels that produce clean energy. This type of operation will
cost zero, since the production of solar panels for electricity, sold,
generating an economic return, allowing you to cover expenses
incurred. The operation is very important for `environmental, ecology
band for the economy. The Eternit, as you know, is composed of
asbestos material that is harmful to health. The replacement of
roofing Eternit with photovoltaic panels makes it possible clean
energy production without polluting emissions into the atmosphere. It
'been calculated that thanks to these devices prevent the emission of
tonnes of CO2 per year. With regard to economic performance, installed
photovoltaic panels, will produce millions of kilowatts, allowing the
savings of thousands of barrels of oil. In addition, the sale of
electricity gains million of Euro, sufficient to cover the costs of
the whole operation, including the removal and disposal of Eternit and
installation of solar panels.
