Solar Energy and Energy Storage for Apartment Associations
A solar power plant helps an apartment association reduce the amount of electricity purchased from the grid and cover part of the building’s common electricity consumption. Electricity generated on-site can be used, for example, for staircase lighting and for operating lifts, pumps, ventilation systems and other equipment used in common areas.
If necessary, the system can be supplemented with an energy storage system, which allows part of the energy generated during the day to be used later. A suitable solution is selected according to the building’s electricity consumption, the technical possibilities of the roof and the conditions of the electricity connection.At the same time, the building’s energy efficiency rating improves, increasing both its value and comfort. Solar panels are a long-term investment in the building’s infrastructure: they last for decades, reduce residents’ financial burden, and make the property more environmentally friendly. Even standard Soviet-era apartment blocks can benefit from solar energy, while new buildings with solar systems more easily meet modern nearly zero-energy consumption standards.
Benefits of Solar Energy for an Apartment Association
How Does It Work?
Support and Financing Opportunities for Apartment Associations
Currently, apartment building renovation loans and apartment building loan guarantees are available through EIS.Financing conditions depend on the scope of the project, the financial capacity of the apartment association and the conditions of the specific financing measure.
Altmer Energy helps assess the technical suitability of the project and prepare a solar energy and energy storage solution, a quotation and the necessary technical source data.
Information updated: 19.08.2026For example, in Estonia, there was previously the targeted KredEx program supporting the installation of solar panels in apartment buildings, and today funds from the Housing Renovation Fund can also be used for solar installations. These measures significantly shorten the payback period for residents.
As a result, your investment is greatly reduced, and even a small building can afford its own solar power station. With subsidies, many HOAs have already installed panels with virtually no additional financial burden on residents – the costs are offset by grants and savings. Don’t miss this opportunity: government programs have limits and deadlines, but with our assistance, you can secure support and make your building modern and energy-efficient with minimal expenses.
Who Is It Suitable For?
A solar power plant may be suitable for an apartment association whose building has a technically suitable installation area and sufficient common electricity consumption to use the energy generated on-site.
Before designing the solution, the condition and load-bearing capacity of the roof, shading, the existing electricity connection, the building’s consumption profile and the technical conditions of the grid operator are assessed.The required roof area and system size depend on the selected panels, installation solution, safety requirements and the building’s actual energy consumption.
The impact of the solar power plant on the energy certificate and the payback period of the investment must be assessed separately for each apartment building.
The investment decision is made by the apartment association in accordance with the applicable decision-making rules and the technical and economic assessment of the project.
Practice shows that when there is a clear profitability calculation, the majority of owners vote in favour. For our part, we are ready to provide your apartment association with all the necessary savings calculations and information about the process so that you can make an informed decision. In summary, a solar power plant is suitable for your building if you aim to reduce utility costs in the long term, increase apartment values and support environmental sustainability – and this is relevant for practically every apartment building.
