SOLHO B.V. develops an innovative and fully off-grid energy system called SPRHOUT (Solar PoweRed Horticultural Off-grid UniT) that, using solar power and thanks to a thermal energy storage system, fulfils the needs of a GBHP.
The SPRHOUT technology is the first renewable solution proposed to power off-grid greenhouse based horticultural projects (GBHP).
Solar energy is harvested by solar thermal collectors in the form of heat, while sea water is collected in a water basin
Thermal energy is stored in the TES system
Advanced algorithms manage the thermal energy in the TES to meet the energy requirements of the greenhouse generating the required amount of heating/cooling, electricity, fresh water and CO2
It runs 24/7 thanks to SOLHO proprietary thermal energy storage (TES) system. We designed an innovative TES with integrated heat extraction, which maximizes the system efficiency and its reliability.
Unique architecture: we developed an innovative modular design facilitating the integration of the SPRHOUT with the greenhouse.
Advanced control strategy: the algorithms to operate the SPRHOUT efficiently and reliably are developed by SOLHO.
It is flexible in terms of design (e.g., power output), modular (skid mounted), and scalable for horticultural projects in a range from 0.1 to 30 hectares.
It can be remotely operated without the need of trained operators on-site, thus less expensive.
It reduces the yearly carbon footprint of a GBHP.
It makes off-grid GBHPs resilient to the volatility in fuel prices
