Objective
To construct a sound and weathertight roofing cover using standard production model PV panels on a conventionally structured pitched roof at the well known UK Centre for Alternative Technology.
To use the PV array to produce its maximum potential of electric energy. To show that such a system is able to be integrated with other roofing materials.
The design innovations lie in the design of the carrier rail system, capable of utilising and production model PV module either framed or unframed.
The PV generator is rated at 12 kWp. Its power is mainly used on site, where it first is stored in the existing on-site battery bank. If the batteries are fully charged then excess energy is fed into the local grid via a power gate.
