173.6 kWp - PV Installation

In general the project was prepared very well and not many unexpected problems occurred. A total of 5 different manufacturers/installing companies were invited for the bidding. The contract was won by Stroomwerk bv from Deventer.

There were two problems with the construction that came out during the design process and at the start of the construction work.

- The systems are design as lightweight flat roof systems with a maximum load of 25kg/m². This is probably the lowest load possible.

In general the roofing material will be covered with a layer of crushed stone to protect the roofing material against UV and the direct sun. The weight of this layer can be compared with the weight of this PV system. However, the client decided to take another roofing material without crushed stone. The total weight of the roof was much lower and so was the construction under it.

With the PV system as an extra load, the dimensions of the steel structure had to be altered in a system with larger dimensions. The cost of this alteration was not in the cost for the PV System but the cause was the weight of the PV system. The municipality and SWAGRO worked together to find some budget space in the design and construction of the building to solve this financial problem.

- There was a delay in the construction of the system because of a temporary shortage of modules due to a change in subsidy rules and a peak in the selling of modules. For this reason the system installation was not finished before January 1, 2004 but at January 29, 2004 (official start).
