ABSTRACT
In order to begin planning a grid-connected PV system and to be able to offer a quotation, a site visit is essential. This enables an assessment of the basic conditions for the PV system.
First, it is important to establish whether the building is suitable for installing a PV system. A thorough initial investigation avoids planning errors and miscalculations in the quotation that is submitted. The installation work for the PV array, the installation site (e.g. for the inverter), the wiring routes, the actual laying of cables and for expanding or modifying the meter cupboard can be better estimated and agreed in consultation with the customer.
