Energy and construction · Prague and Plzeň
Solar PV, batteries and transformer substations. All under one name.
We design and build PV power plants including battery storage, transformer substations and switching stations. We handle permits and grid connection, and monitor completed plants 24 hours a day.
The whole chain under one name
Sun by day, battery by night
We build the power plant, the battery storage and the transformer substation and connect them to the grid. Move the time slider to see how energy flows during the day and at night.

Services
From engineering to plant operation
You don't have to piece the job together from several suppliers. We handle design, paperwork, construction, installation and servicing ourselves and are accountable for the result as a single partner.
PV power plants
A power plant from roof scan through permits and installation to final approval and operation.
More about the serviceBattery storage
Stored energy from your own plant, lower peak demand and backup during grid outages.
More about the service- Switchboards and transformer substationsTransformer substations, MV and LV distribution, inspections and connection to the distribution grid in one package.
- Energy managementAn overview of where, when and how much energy you consume, and data for smarter control.

Servicing and 24/7 monitoring
We do not leave a completed plant unattended
We monitor installed plants around the clock. As soon as a fault occurs, both the technician and you receive an alert, so it is dealt with immediately, not at the next inspection.
For batteries, we monitor cell condition and temperatures. Monitoring includes regular inspections and servicing.
From design to grid connection
Design
Analysis and building scan
We analyse your consumption, survey the building with a drone equipped with a thermal camera and a 3D scanner, and prepare the design documentation.
Permits
Permits and the DSO
We obtain the building permit and handle negotiations with the distribution system operator. You can focus on your business.
Construction
Equipment and installation
We supply the equipment, prepare the site and install the power plant, batteries and transformer substation.
Connection
Final approval and grid connection
This is followed by final building approval, grid connection and handover into operation, including energy management set-up.
24/7 monitoring
Servicing and monitoring
We monitor the completed plant around the clock. If a fault occurs, we alert both the technician and you. Plus regular inspections and long-term servicing.
From our work
Solar PV, batteries, switchboards and transformer substations. We keep adding further projects to the gallery.
