The combination of 947 photovoltaic panels on the roof and shell of the building with a high-capacity battery and cogeneration units ensures almost 100% electricity consumption of the whole building. Along with this, it also ensures the charging of forklifts and electric vehicles.

The 296 kWp photovoltaic power plant has two parts - on the facade and on the flat roof. Part of the façade will be complemented by the production of electricity by cogeneration units, especially in the winter. “All black” panels are used for the facade. In addition to the nickname for the New Zealand rugby team, it is also a designation of a photovoltaic panel, which has a maximum of visible parts in black colour. Under optimal conditions, the power of 1 panel is 320 Wp. The photovoltaic power on the facade is 77 kWp. The winter sun is only about 20° above the horizon, and therefore the installation of photovoltaics on the facade is suitable with regard to the need for year-round electricity production.

“We very much welcome and support green energy sources. They are environmentally friendly and thus socially responsible for future generations. It is an example of the effective use of European subsidies, namely Adler was worth more than 10 million crowns” says the Deputy Prime Minister and Minister of Industry and Trade Karel Havlíček and adds: “Projects such as hybrid photovoltaic system also contribute to the fulfilling the Czech Republic goals in terms of the share of renewable sources in electricity production. They are also an example of a unique combination of the cutting-edge technology with a modern control and monitoring system.”
“The whole project is our most important and we are pleased with its successful implementation, but it is one of many, by which we fulfil the goals of responsible business of the company” says Radek Veselý's statutory director of ADLER Czech.

The battery capacity (up to 360 kWh) can be “software-controlled” - depending on current usage and operating requirements. For example, the system can be set so that the batteries are always charged to 50 percent, and thus the object is ready for the case of blackout. The batteries have two separate converters with a total charging and discharging power of 200 kW. Up to this power, it is possible to operate in standby mode - for example in the event of a power failure. Batteries are a combination of lithium, iron and phosphate with regard to high safety especially in terms of burning. The expected service life is 6000 cycles. With fully charged batteries, the warehouse can operate for several hours in an emergency case. Moreover, if the sun is shining, or if it is possible to start cogeneration units, independence from the grid will be no problem for a few days. At full capacity, the photovoltaic system produces enough electricity to supply 100 family houses.
Charging of forklifts and electric cars can take place in three basic modes: I have to charge right now, just charging on the next day is enough for me and I can wait more days. In the case of the second and third variant, the system evaluates when it will be most advantageous in terms of energy price and also current consumption of the building. The weather forecast is also taken into account. For example, if we charge over the weekend, the system will wait until Sunday if nice weather is reported. We then assume that there will be enough energy from the photovoltaic system = energy will be “for free”.

- Power output: 296 kWp
- Annual production: approx. 280,000 kWh
- Number of PV modules: 947 pcs

The investment in a unique hybrid solar system reached 15 million crowns and the project was built in three months. The zero emission photovoltaic power plant complex, together with a three million investment in condensing cogeneration units, which ensure environmentally friendly production of electricity and heat for storage, will clearly reduce the carbon footprint of the logistics centre to a minimum.

The project entitled Acquisition of accumulation including RES in the ADLER Czech, a.s., project number: CZ.01.3.14/0.0/0.0/16_132/0010593 is co-financed by the European Union from the OP EIC. The subject of the project is to increase the self-sufficiency in the use of energy within the operation and activities of the ADLER Czech, a.s. The implementation of the project will have a positive impact on the environment and will also bring financial savings.
