From light to electricity

Implementation and planning of photovoltaic systems

"Photovoltaics" refers to the direct conversion of light into electricity. The physical principle – the photoelectric effect – was discovered as early as 1839. Solar cells have been powering spacecraft since 1958 and have proven to be very reliable.

Solar cells have already been used on a significant scale on earth for around 20 years. Here, it is possible to convert the direct current generated into grid-compliant alternating current in inverters and feed it into the public grid. In more and more countries, electricity fed into the grid is remunerated in an economically enticing way or consumed by the producer themselves. That is why our team at MaxSolar has a high level of experience and expertise in the planning of photovoltaic systems.

Areas of application

When planning photovoltaic systems, green compensation areas from economic, residential or military use are considered for energy systems. So, spoil heaps, former open-cast mining areas, military training areas and ammunition depots. Also areas along motorways or railway tracks at a distance of up to 110 metres. Agricultural land and grassland can only be considered for the planning of photovoltaic systems if they are located in a less-favoured area per Directive 86/465/EEC and have been approved for PV use by the federal states.

Components

We take into account some of the components of the installation as early as in the photovoltaic system planning stage: We install the modules for ground-mounted photovoltaic systems by means of fixed mounting. Regardless of the substrate, a steel or aluminium frame is anchored in the ground by pile driving or screwed to concrete blocks; the angle of the modules is not changed after assembly.

Benefit

Fallow and unused open spaces can be used economically and profitably. There can be a profit share via the ongoing yields of the photovoltaic system or a one-off lease payment can be made. A study by the bne [German Association of Energy Market Innovators] also shows that ground-mounted systems make a high contribution to regional biodiversity and that the installation of a solar park makes it possible to significantly enhance the ecological value of the land compared to arable land or intensive grassland use.

Rooftop photovoltaic systems

Areas of application

Commercial roof areas offer great potential and are integrated into the planning of photovoltaic systems from the outset. Not only gable roofs are suitable for the installation of a photovoltaic system. Many warehouses or production halls offer suitable conditions. We have also successfully installed photovoltaic systems on rare types of construction, such as sawtooth roofs, and sustainably increased the value of the commercial property.

Components

The high-performance solar modules of a rooftop photovoltaic system are mounted on the flat or sloping roof surface on a substructure. On gable roofs, the installation is carried out using roof hooks mounted on the rafters.

Benefits

An integral part of the planning of photovoltaic systems is the identification of benefits for companies. Currently, they benefit from a cost degression of 80 percent. A commercial rooftop system currently costs 600 to 800 euros per kW to be installed, depending on the size. The solar electricity generated by the solar power plants on the roof then costs between 6 and 8 cents (plus EEG [German renewable energy sources act] contribution) per kWh.
