Photoelectric Solar Modules We suggest installation of photoelectric solar modules as an additional feature to compensate the seasonal variation of wind supply. Solar micro power stations of 50–200 W are a perfect choice to be used in combination with wind micro-turbines. 1 kWh of electricity is consumed to produce between 2 kWh and 4-5 kWh of thermal energy; the output depends on the outdoor and indoor temperatures, as well as the type of the thermal pump. In a house of 200 m2 with decent thermal insulation, the annual consumption of energy for heating and hot water would make up 24,000 kWh. Thermal pumps help to get the same amount of heat with 6,000–8,000 kWh. Moreover, thermal pumps can be used to cool the indoor air in summer!
A system for electricity management, distribution and accumulation, which connects the said sources of energy with the equipment that consumes the energy Tanks of hot water accumulate thermal energy, and batteries accumulate electricity, which is consumed upon demand. This helps to avoid the dependence on momentary environmental conditions (small wind, overcast sky). Should the unfavourable weather conditions persist, the system would use electricity from the global power grid. A more cost-efficient option for secluded sites, which lack access to the power grid, could be installation of larger capacity batteries, which would be sufficient to ensure energy reserves for a few days or even a week.
