Self-sufficiency in energy supply
What is self-sufficiency in electricity supply?
The self-sufficiency of flats, detached houses and commercial properties refers to the ability of these buildings to meet their own energy and resource requirements largely independently of external supply systems.
This can be achieved by utilising renewable energy sources such as solar, hydro or wind power, efficient energy systems. Self-sufficient buildings are therefore able to minimise their energy consumption and cover a large part of their needs themselves, which leads to energy efficiency and sustainability.
What should you look out for in self-sufficient systems?
Careful planning and implementation of various technologies and measures is required in order to supply a property with electricity as independently as possible from the local energy supplier and thus be able to operate a building up to 80% self-sufficiently. Invisia can support you in this.
Here are the 8 most important points that are necessary for this:
1.
Photovoltaic (PV) systems
The installation of photovoltaic systems on the roof or in other suitable locations on the building is of crucial importance. They convert sunlight into electrical energy and can cover a large part of the electricity demand.
2.
High-quality solar modules
The use of high-quality and efficient solar modules is crucial to maximise the amount of energy generated from solar radiation. Invisia helps with the selection of suppliers and manufacturers. There can also be big differences in delivery times.
3.
Battery storage
The integration of battery storage systems makes it possible to store surplus solar energy during sunny periods and use it later when the sun is not shining, i.e. at night or on cloudy days.
4.
Energiemanagementsystem (EMS)
Intelligent energy management can optimise the timing of energy consumption in order to maximise self-consumption of the solar energy generated.
5.
ZEV – pooling for self-consumption
A ZEV enables several parties in a property to use their generated electricity together and share surpluses among themselves, which reduces dependence on the public grid and promotes self-sufficiency in electricity.
6.
Monitoring and maintenance
Regular monitoring and professional maintenance of the solar modules and battery storage are important to ensure the efficiency and reliability of the self-sufficient system.
Invisia supports you in this with the Invisia app and simple monitoring.
7.
Heat pump
A heat pump can contribute to the energy self-sufficiency of a property by converting efficiently generated electrical energy, e.g. from a photovoltaic system, into heat and thus reducing the need for externally supplied heating energy.
8.
Energy efficiency measures
Implementing energy efficiency measures in buildings, such as LED lighting, energy-efficient appliances, thermal insulation and good insulation, helps to reduce energy consumption.
How can Invisia support you?
Basically, it can be said that energy self-sufficiency of up to 80% cannot be achieved without a professional energy management system (EMS).
Another prerequisite is that heat and hot water are generated with a heat pump and the boiler therefore functions as a cost-effective energy storage system.
It is currently assumed that a self-consumption of the electricity generated of approx. 25% can be achieved without an EMS.
Up to 70% self-sufficiency can be achieved if a battery is integrated into the energy system.
The optimum solution and self-consumption of up to 80% can be achieved with the Invisia EMS and a battery storage system.
