Borowski solar system installations: Clear-cut climate protection targets

Solar system installer BorowsBorowski GmbH, which had its start as a specialist company in the field of antenna technology and electrical engineering, has now been doing business as a solar system installer for over ten years. And the company also uses and tests its own range of products – from photovoltaic installations, to storage units, to control systems – which offers clear benefits in terms of climate protection.

Playing an active role in climate protection is part of the company’s business model. Borowski GmbH acts as a trailblazer when it comes to using new technologies, which enables the company to gain experience with them and continually expand the required expertise.
And Managing Director Markus Borowski is a man who truly acts on his convictions: the entrepreneur gives talks on the subject of photovoltaics and operates community solar installations, thereby promoting public awareness of PV-related topics. Borowski GmbH joined the Ökoprofit network (an ecological project for integrated environmental technology) in Essen back in 2006 and received the Essen Environmental Award in 2012.

Climate protection objective:

Climate protection target:

  • Halving CO2 emissions by 2020
  • Installing a solar power storage unit (6–8 kWh net capacity)
  • Commissioning a second photovoltaic system (10kW) with a battery storage unit
  • Replacement of two cars with electric cars

Bringing new technologies into play

A photovoltaic system with an overall 17 kilowatt-peak power output and an energy yield of approx. 13,000 kilowatt-hours was put into operation in 2005 (grid feed-in). In comparison to the current electricity mix, this saves just under 7.5 tonnes of CO2 emissions. Two years later, a CHP unit was installed as a heating system and to generate electricity for the company’s own requirements. This unit produces approx. 37,000 kilowatt-hours of heat and 10,000 kilowatt-hours of electricity per year, with an overall efficiency of more than 90 per cent. A photovoltaic system for the company’s own consumption was constructed in 2012 with a 5.5 kilowatt-peak output and annual production of approx. 5,000 kilowatt-hours.

In 2013, the company installed a storage unit with a net storage capacity of two kilowatt-hours as part of a field test. This enabled the company to gain valuable experience that benefits its customers. A smart home system used to control lighting and heating was installed in 2015, resulting in an annual reduction in heating costs of 20 per cent.

Halving CO2 emissions by 2020

The company’s goal for 2020 is to produce only half as much CO2 emissions as it did in 2003, when it began offering services in the solar segment. To this end, Borowski is planning to implement the following individual measures in the coming years: the installation of a larger storage unit (6–8 kilowatt-hours net capacity) is planned for 2016 with the goal of achieving a degree of self-sufficiency of 80 per cent by combining a photovoltaic system, a CHP unit and a storage device.

Borowski has already identified areas of action for the coming years as well. Further efficiency potentials in the existing heating system were identified, and the company is planning to tap into these in 2017. And in 2018, Borowski will begin using electric and hybrid technologies in its company vehicles.
