The energy demand of the module houses and external plants (e.g. aquaponics) is continuously secured autonomously by combined technologies. Preferably, the energy management is realized in a dedicated energy container.<\/p>

- HCPV Photovoltaics

- Wind energy\u00a0<\/u><\/p>

- Heat pumps
<\/u><\/p>

- Solar energy <\/u><\/p>

Some systems in concentrator photovoltaics are operated with active cooling, so that thermal energy can be used in addition to electrical energy (CPV-T systems). Overall efficiencies of more than 75% have already been realized in CPV-T systems. CPV systems are best suited to sunny and dry locations.<\/p>

There, drinking water is often obtained by desalination plants (see under Water management). Therefore, a combination of the CPV-T and desalination systems is ideal.<\/p>

Modular solutions are offered for the storage of excess energy via batteries or other innovative options (fuel cells).<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

There are mainly 2 types of energy generators managed in the energy container:<\/p>\n

- Solar system
- Wind turbines<\/p>\n

The solar system charges the batteries directly via the associated PV control (PV = photovoltaic). This plant generates direct current (DC). The controller can regulate the feed-in or charging process automatically or manually. Likewise the feed can be interrupted or switched off. The wind turbines generate alternating current (AC). Each wind turbine has its own controller and load resistor.<\/p>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t

\n\t\t\t\t\t\t\t\t\tThe generators of the wind turbines feed into their respective regulator, which rectifies the voltage and outputs it to the batteries via a regulated load resistor. This is necessary because, due to the rotational speed of the rotors, too high a voltage can be generated, which is therefore also too high for the charging process. The load resistors regulate the output voltage per wind turbine and compensate all voltage values above the limit voltage. The regulated output voltage then charges the batteries directly. These are usually lead-acid batteries. The size of the battery pack is adapted to the sum of the energy generators.\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
