Solar power systems and car charging for a housing association

Photovoltaic systems are perfect for both the smallest and largest housing companies that want to reduce their electricity bills and carbon footprint. A professionally designed and implemented system is a profitable investment, and the high and highly fluctuating electricity prices make the solar electricity system even more profitable and promote the building society's energy self-sufficiency.

The central parts of the solar system are the solar panels and the inverter. The inverter can be either 1- or 3-phase and its task is to convert the direct current (DC) produced by the solar panels into alternating current (AC) suitable for the property and the electrical network. The solar panels are connected via an inverter to the property's power center and the power grid.

A few key factors must always be taken into account when setting up photovoltaic systems. The size of the system depends on the building society's energy needs, and in the planning phase, the dimensioning of the system is determined based on the roof space of the solar panels, the average energy consumption and the number of solar panels. When setting up the system, it is also important to consider financing and maintaining the system, and to educate the members of the housing association about the advantages of the solar electric system and its correct use and maintenance. This helps ensure that the system is used effectively.

In the general meeting, the residents of the housing association can make a decision on the introduction of the system and what the electricity produced by the system will be used for. Surplus production from the solar power system can either be sold back to the grid and get a refund on the electricity bill or, for example, be used as part of the charging system for electric cars.

We have long experience in charging solutions for electric cars for housing associations, companies as well as consumers and special expertise in connecting charging solutions to solar power systems.

Connecting car charging to solar power

By combining electric car charging with a solar power system, you get the best out of the whole. Various smart charging solutions enable the utilization of surplus solar energy for electric car charging, allowing you to charge your electric car as cost-effectively and environmentally friendly as possible.

Combining car charging with a solar power system offers several advantages. By using renewable energy from solar power systems to charge electric cars, the carbon footprint of passenger traffic can be significantly reduced. By producing their own electricity with solar power systems, electric vehicle owners become less dependent on the grid and can be more self-sufficient in their energy use. Solar charging also brings noticeable cost savings over time. Future technologies also offer improved grid stability, harnessing electric car batteries as energy storage for use by the entire grid. This new technology is V2G (Vehicle-to-grid) and loosely translates as "vehicle to grid" and offers electric vehicle owners the opportunity to earn money by selling their excess battery power back to the grid.

Photovoltaic system and energy optimization

By establishing a solar electricity system, the building society can utilize renewable energy and thus give shareholders the opportunity to make responsible energy choices. Photovoltaic systems are developing at a fast pace and are even more cost-effective, offering more and more people the opportunity to make environmentally sustainable choices for their own electricity use.

The photovoltaic system should be optimized to ensure maximum efficiency. Optimizing must ensure that the system is designed and dimensioned correctly, as well as the correct selection of components, such as solar panels, inverters and batteries, and their dimensioning according to the purpose of use. By planning in advance to optimize the solar power system, energy production can be maximized and costs minimized, making the whole thing an even more profitable and attractive option for many homeowners and companies. System optimization includes many areas, the most important of which are system maintenance and service, energy management including, for example, the use of energy-efficient devices, implementation of energy storage solutions and management of energy consumption during peak times, as well as active monitoring of the system in case of possible problems. Monitoring can include monitoring of energy production, battery charge level and system performance.

The energy community and the financial viability of solar electricity

Investing in a solar electric system not only brings tangible benefits to the electricity bills of the residents and the housing association, but it also increases the value of the housing association. In addition to this, solar electricity is an ecological, renewable form of energy and a real environmental act for the building company.

The housing association can form an energy community to utilize the solar electricity it produces directly for its own use, so residents save on electricity purchase costs. The energy community brings significant savings to both the housing association and the shareholders and increases the value of the housing association. By establishing an energy community, the housing association can also use the electricity it produces to charge shared or residents' own electric cars. Solar power systems should be sized according to the housing association's own needs, but if the system produces more electricity than it is used, surplus production is created. Surplus production can either be stored locally, if an energy storage is connected to the system, or alternatively sold back to the electricity grid, in which case the amount of purchased electricity is smaller and, based on the credit calculation, the partners of the energy community are billed less. The refund calculation is coming into use nationwide during 2023.

The benefits of the energy community formed by the housing company:

• Lower energy costs: By pooling resources and sharing energy, energy community members can save money on their energy bills.
• Better energy efficiency: Energy communities can implement energy-efficient measures, such as using renewable energy sources, reducing energy consumption and using smart technologies to manage energy use.
• Increasing the use of renewable energy reduces dependence on fossil fuels and reduces carbon dioxide emissions.
• Better energy security: Energy communities can create a more sustainable and safer energy system by diversifying their energy sources and reducing their dependence on centralized energy networks.
• Community engagement: Energy communities can bring people together and foster a sense of community ownership and responsibility for energy resources.
• Economic benefits: Energy communities can create local jobs and support local businesses involved in the production and distribution of renewable energy sources.

Overall, energy communities offer a range of benefits that can improve energy sustainability, affordability, and security while promoting community engagement and economic development.

The establishment of an energy community requires a decision, but it can be implemented as a joint project of the housing association or as a separate project of several partners.
