Solar Panels for Business and Apartment Associations
We design and install solar power plants for commercial buildings, production and warehouse facilities, and apartment associations. We maximise self-consumption, assess your grid connection capacity, and provide a clear payback calculation before you invest.
A solar plant that pays for itself on your company's balance sheet
A commercial, production or warehouse building usually has a large, unobstructed roof area and steady daytime consumption, exactly the combination that makes a solar plant commercially worthwhile. Unlike a household, we are not talking about a 5-10 kW system here, but about plants of tens to hundreds of kilowatts, where every detail, pitch, shading, inverter choice and grid connection capacity, affects yield and payback.
ProfiElekter has over 17 years of experience in electrical work and holds the right to operate independently (competence, MTR registration), which is required for designing larger plants and connecting them to the grid. We work with hotels, commercial and office buildings, and industrial sites in Tallinn, Tartu and across Estonia.
For apartment associations the logic is similar: a solar plant covers the building's common electricity, stairwell lighting, lifts, ventilation and heating substation pumps, and reduces the association's monthly electricity bill. We help the association think through both the technical solution and the application process.
Solar solutions for every type of building
Commercial and office rooftops
A flat-roof plant that covers the daytime consumption of office, retail or service space. Ballast mounting does not damage the roof membrane, and the panels are oriented to cover maximum self-consumption.
Production and warehouse buildings
Industrial buildings with large roof areas are well suited to 100 kW+ plants. Steady daytime load means a large share of the output is consumed on site, which matters more for payback than the sheer number of panels.
Maximising self-consumption
Electricity you produce yourself is always cheaper than electricity bought from the grid. We size the plant to your consumption profile so that as much of the output as possible covers your own use, rather than going to the grid at a low price.
Battery storage and EV charging
A larger battery storage system shifts electricity produced during the day to the evening peak load and provides backup power. On request we add electric vehicle charging points that integrate into one system with your solar output.
Grid connection capacity and selling to the grid
For a larger plant, the grid connection capacity and the state of the grid are decisive, and in many areas available capacity is limited. We assess the capacity of your connection point before design and, where needed, arrange the producer connection application.
Apartment association solar plant
An apartment association plant covers the building's common electricity and reduces the association's fixed costs. The KredEx apartment building solar panel grant covers, subject to its terms, up to 30% of eligible costs, up to 150,000 EUR per applicant. We help size the plant so that it fits within the grant conditions.
Who a B2B solar plant suits
- Production and warehouse companies where much of the electricity is consumed during the day
- Owners and managers of commercial, office and retail property
- Hotels and accommodation providers with large, steady consumption
- Apartment associations looking to cut their common electricity costs
- Property developers adding a plant to a new project already at the construction stage
- Companies planning electric vehicle charging or battery storage
The competence and experience a larger plant demands
ProfiElekter OU has been operating for over 17 years and holds the right to operate independently (competence) and an MTR registration, which is required for electrical work on commercial and industrial sites and for arranging producer grid connections. We do the work properly, from design through documentation to grid connection, so that the plant goes legally into operation and the requirements for the occupancy permit are met. We operate in Tallinn, Tartu and, on a project basis, across Estonia.
Frequently asked questions
The right size does not come from the roof area, but from your consumption profile. The goal is for as much of the output as possible to be used immediately, because self-consumed electricity is clearly more valuable than surplus sold to the grid. We look at your hourly consumption and size the plant accordingly, and the optimal plant is often smaller than the roof could fit.
The payback period depends on your consumption profile, the price of electricity, the share of self-consumption and the connection cost, so we cannot promise a specific figure before doing the calculation. As a rule, plants where a large share of output is consumed on site pay back better. We provide a clear payback calculation for your site, and you can also use the price calculator for an initial estimate.
Yes. The KredEx (EIS) apartment building solar panel grant covers, subject to its terms, up to 30% of eligible costs, with a maximum of 150,000 EUR per applicant. The supported generation equipment must be installed on the roof or facade of the apartment building. Conditions and application deadlines change from round to round, so it is worth checking EIS's current rules before starting a project, and we help plan the plant so that it fits the application.
Grid connection capacity is the capacity at which your connection point is connected to the electricity grid; it limits both consumption and the output you can feed into the grid. For a larger plant, the existing connection and the local grid may not be able to take all the output, and in many areas available capacity is limited. That is why we always check the capacity of the connection point before design and, where needed, arrange the producer connection application.
In principle yes, but it depends on the plant's capacity, the connection agreement and the free capacity available in the grid. Smaller plants are treated as a typical micro or small producer, while a larger plant connects under the producer connection arrangement. This is exactly why it is commercially smarter to size the plant to cover self-consumption rather than to sell surplus, and we settle this already at the design stage.
