GridParity: double glass modules for 100 parking spaces

The parking lot of a leisure pool in Plettenberg has been fitted with translucent photovoltaic roofs by specialists GridParity. The construction did not require any large-scale demolition of the parking areas.

The parking lot PV specialist GridParity has used double-glazed modules to cover 100 parking spaces in Plettenberg, Sauerland. According to the company, the structures are also suitable for use where the parking spaces are not to be torn up. And this was precisely the requirement of the Plettenberg public utility company as operator of the leisure pool, whose parking lot was to receive PV. This was not to be excavated for the concrete foundations. In addition, the construction had to be carried out without significantly affecting the parking lot.

To take this into account, GridParity therefore used large screw anchors with specially developed fixing plates for the steel supports. Assembly took place in the first week.

In the second week of work, the prefabricated glulam beams were installed and painted white with a semi-transparent wood preservative.  In the 3rd week, the translucent double-glazed modules with a special attachment were finally installed.

Short construction times and more light

The modules on the 100 parking spaces add up to a connected load of over 300 kWp and generate over 300,000 kWh of electricity per year, which is used directly in the leisure pool. According to GridParity, the positive experience with the construction process is motivating the municipal utilities to start planning an expansion.

A decisive factor for the attractiveness of GridParity's PV parking area is the bright character of the carports by dispensing with a closed sheet steel cover. This is made possible by using semi-transparent double glass modules with overhead approval and watertight installation. This results in solutions that combine aesthetics with functionality, low production costs and short construction times.

Despite many advantages and some subsidy programs, parking lot PV is still not very widespread. According to GridParity, architects and investors usually cite the unattractive design of the structures, which are perceived as "dark caves", as a reason for this. Furthermore, the parking area is usually excavated for construction in order to install the solid concrete foundations. The paving then has to be extensively repaired or rebuilt from scratch. The closure of the parking areas required for this, usually for several months, is not acceptable for most companies.
