Suitable for business cases
Solartag is the ideal solution for commercial projects – both new construction and renovation. The stylish design enhances the building’s appearance while also producing green electricity. Perfect for both modern and heritage worthy properties.
For new construction and renovation
Solartag is ideally suited for commercial buildings, both for new construction and renovation. The roof solution not only contributes green power, but also supports the architectural expression of the building.
Unlike traditional solar cells, Solartags matte surface integrates discreetly into the surrounding area without glare. This makes the solution particularly suitable for commercial buildings in urban environments, where black roof surfaces such as slate and tile are often found - as well as for renovation of heritage and historical properties, where aesthetics and overall impression are crucial.
Should the roof count in your green accounting?
A Solartag greatly affects a project's overall CO₂ footprint. Although CO₂ is also used to produce a new roof, the energy that a Solartag produces, will help achieve CO₂ break even in just a few years and subsequently contribute to a positive CO₂ footprint for the rest of the long lifespan of a Solartag.
The municipal requirements for Kirkens Hus in Varde formed a large part of the design work regarding energy optimization. However, ordinary solar cells were not allowed to be used, due to the glare problem. Therefore, Solartag was chosen as the supplier for the project.

Housing association gets green electricity
The residents of Amsterdamgården housing association in Hørsholm decided to invest in a Solartag in 2020, when the old roof was due for replacement.
In just 3.4 years, the residents paid back their additional investment in the Solartag and also had cheaper electricity during the same period. Their choice of Solartag is a fantastic example of how a green investment pays off.
The residents can look forward to a fixed low price for electricity, while the Solartag helps pay the rest of the investment back home. The housing association has also invested in batteries and electric car chargers, as well as additional energy renovations to further accelerate their investment.
Power for resale or shared power
The production of a Solartag is determined during a dialogue with the developer, so that it matches the property's electricity consumption and possible future needs. Solartag produces electricity directly via the roof, and in a rental property or housing association, the electricity can be used in two ways:
For shared use - The electricity can be used for shared areas such as stairwells, laundry rooms or outdoor lighting. This means lower shared electricity costs.
For resale - The electricity can be sold on to the residents of the property. Each home gets a bi-meter that registers how much electricity they use from the Solartag, and they then pay for the electricity, that they have consumed.
The electricity is only sold within the property's cadastral area, but this has a big advantage: Because the electricity is produced and used in the same place, there are no transport costs to the electricity grid and no taxes. This means that the value of the electricity stays in the property instead of going to the public electricity grid. When electricity is sold to the residents, the normal cost of electricity instead becomes income for the owner or the community in the housing association.
Good return and short or long amortization
A Solartag is considered an integral part of the building and can be depreciated together with the property if it is a depreciable building, such as a factory or warehouse. Depreciation can be done at up to 4% per year, corresponding to a straight-line depreciation over 25 years.
When installing a Solartag on an existing building, it is considered a conversion. In this case, the costs can be fully or partially immediately depreciated according to the applicable rules for conversion of commercial buildings. To ensure the best financial and technical solution, Solartag is happy to refer you to qualified developer advisors with insight into the legislation and the relevant depreciation rules.
In addition, we can provide contact with an independent consulting engineer who can perform an impartial PvSol calculation. This calculation estimates the annual electricity production and forms the basis for an accurate financial assessment. PvSol calculations can also be delivered with 2D or 3D illustrations of your Solartag project.
