Answer:A material designed to produce passive solar energy can achieve energy savings of 70%. In addition to this great advantage, we show you what are the main benefits that passive solar energy can bring us:
Reduced maintenance cost. Since it has no external equipment to harness the energy, the maintenance required will be practically nil.
It is 100% renewable energy. It does not emit polluting gases and helps to maintain the environment, in addition to being an inexhaustible source which is the sun and we can always have it.
Energy and economic savings.
Reduction in the cost of electricity and gas bills.
Compatible with solar panel installations. In fact, it is currently considered as a complementary technology.
APPLICATIONS :Active solar energy is mainly used to obtain sanitary hot water, heating systems and to transform solar radiation into electrical energy.
Active solar technology is also used to produce air currents for ventilation or cooling and to store heat for later use. In any of these processes, the use of pumps and fans is required.
Other uses of active solar energy are:
Water purification.
Drying.
Evaporation.
Distillation.
Solar batteries.
Solar chargers.
Energy for street lighting, traffic signals and roads.
