Joint exploitation of solar power and rain

Here we are presenting three ideas around water and solar energ. The surfaces of solar modules either PV or solar thermal are capable of collecting clean rain water. Also floating units may be used to generate heat and electric power. During the recovery of the soil, the land may be used for Agri-PV. The weight is implemented via water tanks, which after depleting when moving from the land help to grow crops in the next season.
