10.3 Photo-Voltaic system on the roof<br />
System description<br />
A photovoltaic system, also known as a solar PV system, is an energy system that is designed to transform the energy<br />
from the sun into electricity by means of photovoltaics. This system is safe, reliable, low-maintenance, and provides green<br />
energy without on-site pollution or emissions.<br />
To maximise the feasibility of the system, at this stage, it is recommended to utilise the majority of the multi-use hall roof<br />
which can be made relatively easily and safely accessible from the Level 1 plant deck by means of stairs.<br />
An extensive Photo-Voltaic system can be accommodated on the main church roof.<br />
PV system maintenance<br />
The objective is to reduce health and safety risk associated with the PV system and its maintenance. The PV system will<br />
be designed with appropriate access and maintenance.<br />
The system will be fully coordinated with other aspects of the project such as Architecture, plant, wildlife, etc.<br />
Cleaning of the PV system<br />
Most of the time the rain will keep the solar panels clean. However, a build-up of dirt can affect the system performance.<br />
The degree of soiling will depend on the weather. In extreme case, when dust accumulates, the PV can experience<br />
significant energy production reduction. The design of the system will aim to minimise uneven soiling either through<br />
tilting the panels at 10 plus more degrees, regular cleaning regime may be utilized to increase the overall system<br />
efficiency.<br />
