SOLHO has developed an innovative sustainable energy system called SPRHOUT, the most effective renewable solution to power greenhouse farms.

By using solar power, the SPRHOUT enables the complete energy self-sufficiency of a greenhouse farm and up to 100% operational savings, thus opening the door to unparalleled growth opportunities for manufacturers, owners, and developers of greenhouse farms.


The SPRHOUT system operates harvesting solar energy in the solar field and storing it in the form of heat in the thermal energy storage. The stored energy is withdrawn when needed to heat up the greenhouse and/or to be converted into cooling by means of a thermal driven chiller. The SPRHOUT features a backup unit (e.g., a biogas or fossil fuel burner) which makes up for missing solar input and guarantees 100% redundancy minimizing the risks for the crop.
