A solar radiator is a structure producing two cross shades in corridors, it dissipates solar energy for protecting corridors from excess of solar energy, the average temperature on the soil in the corridors slows down considerably therefore there is a decrease of the evaporation of moister in such corridors, the solar radiator is suitable to produce at least two cross protective shades in the same corridor and is suitable to collect, transmit and dissipate passively, without causing pollution or using other power, at least part of the energy of the solar radiation that strikes its panels. The solar radiator is designed to protect corridors, crops and plants against excessive solar radiation and moister evaporation.
