FAQ

To prepare a proposal, we only need three things: photos or a site visit of the property or location, your annual electricity consumption, the price you pay for it, and your vision for how you want to use the generated energy. Based on this information, we will design a power plant of optimal size and prepare a calculation. Contact us for a quote.

We handle the entire process of building a solar power plant — from the initial design to long-term servicing. We take care of consumption analysis, the design of the optimal solution, project documentation, arranging subsidies and all necessary permits, including connection to the distribution grid. This also includes custom-made mounting structures, the installation itself, and subsequent monitoring and servicing throughout the plant's operation.

The preparatory phase, including obtaining all permits, typically takes about 6–12 months. It covers consumption analysis, project documentation, arranging the connection to the distribution grid, and, where applicable, a building permit. The overall preparation time depends mainly on the size of the project and the complexity of the permitting process — particularly on whether a building permit is required. For smaller installations, for example on municipal buildings, the entire process from first contact to launch takes roughly 6–12 months; for industrial halls and ground-mounted plants it takes 10–18 months. The installation itself then takes a matter of weeks.

We determine the price individually after an analysis, as each property has a different roof, consumption, and conditions, and the price per unit of power decreases with the size of the installation. To give you an idea: for a model project of 200 kWp on a production hall roof, the total costs – including construction, panels, inverters, project documentation, and installation – amount to approximately 5 million CZK, or roughly 25,000 CZK per kWp. Our price always includes a complete turnkey solution. Based on your consumption and location, we will prepare a specific quote, including the return on investment.

Check out our Case Study: PV System for an Industrial Business, or read the article The Economics of PV Projects.

We calculate the return on investment individually based on your consumption, installation size, available subsidies, and options for utilizing surplus energy. For business installations with a good self-consumption ratio, the estimated payback period is around 6 years, or even less with subsidies. We predict production using the PVGIS system with an accuracy of up to 5%, so you know what to expect from your investment beforehand. For your specific case, we will prepare a detailed ROI analysis.

Not necessarily. The system can also operate without batteries, where you consume energy directly as it's produced and feed surpluses into the grid or share them with other properties.

Batteries are a valuable addition if you want to maximize energy use even when the sun isn't shining, manage peak demand, or provide backup during a grid outage.

You can sell surplus energy back to the grid, provided your distributor allows it. Surplus energy can also be utilized in your other properties through energy sharing. This means that energy generated at one building can cover consumption in other facilities. When sharing via the distribution network, you only pay distribution fees, which significantly increases the overall system's efficiency.

Yes, as part of the PV system installation, we will handle the complete permitting process for you, including the building permit procedure. For installations up to 100 kWp, a building permit is generally not required in most cases (as of August 2025, according to the amendment to the Energy Act) – however, it always depends on the specific project and location. For photovoltaic power plants over 100 kWp, and for other requirements such as a license from the Energy Regulatory Office, we will arrange all necessary permits and communication with authorities for you, including structural analysis and fire safety solutions.

Yes. We can provide a structural assessment of the roof to determine if the structure can bear the weight of the installation. For installations over 100 kWp, where a building permit is required, this is a standard part of the project documentation.

We have our own service team and facilities, including spare parts warehouses. Furthermore, our monitoring center continuously tracks the power plant, allowing us to resolve up to 90% of potential faults remotely without a technician visit. This enables us to react quickly to technical issues and minimize downtime.

We handle the basic maintenance. Our cooperation doesn't end with the launch – we connect the power plant to a monitoring center that tracks it 24 hours a day, perform regular checks, inspections, and any warranty and post-warranty repairs.

Learn how we take care of our installed photovoltaic power plants in the article Service Department.

We provide a 5-year warranty on the entire installation, 10 years on batteries and inverters, and up to 25 years on solar panels. Throughout this period, we provide service and support. As a stable company with over a decade of history, we are ready to be your partner for the entire lifespan of the power plant.

It depends on the chosen sharing mode. In the active customer mode, a sharing group can include up to 11 metering points in total across the entire Czech Republic. In the energy community mode or when sharing within an apartment building, this can be up to 1,000 points.

From July 2024, it will be possible to use energy generated in one building across your other buildings. This requires modifying metering points in accordance with the distributor's connection conditions and installing a four-quadrant electricity meter. Subsequently, the Energy Data Center system automatically distributes energy among the individual buildings according to your predefined rules, without the need for manual intervention.

Yes, thanks to our own 12,000 m² production facility equipped with CNC machines, we can manufacture structures precisely according to your needs. We are not dependent on external suppliers, which allows us to guarantee both quality and competitive pricing. We also specialize in innovative solutions, such as carports (parking canopies) or agrivoltaics.

Yes. New legislation (Decree No. 425/2024 Coll.) allows for the installation of agrivoltaics, which combines agricultural activity with energy production on a single plot of land. The land remains in agricultural use, and you retain your eligibility for agricultural subsidies. We have implemented the first construction-approved agrivoltaic project in the Czech Republic, specifically for Moravian Oil Mines.

Everything you need to know about agrivoltaics you can learn in our article.
