Liverpool primary school’s photovoltaic installation over the next 20 years. The 24 kW system is part of a regeneration scheme for the Kingsley Community School, which is seeking to reduce its long-term electricity bills and its carbon footprint. The 24.3 kWp Solar PV system on the roof will generate an estimated 19,270 kWh per year, which equates to an income and savings of £4187.36 per year. Mark Reynolds, director of installers, Feed-it-
Green, said: “A photovoltaic installation is a long term investment and it is important that it stays up and running throughout its projected lifespan. “The cabling is exposed to all that the British
weather can throw at it. Not only do the cables need protecting from UV light, ingress from water and dust and temperatures ranging from below freezing to a hot summer’s day, but mechanical forces due to wind and other factors such as rodents or birds. “As a public building we also need to protect the cables from vandalism and potential cable

lexible conduit from Flexicon will help to keep the power running for a
theft, so mechanical protection is vital. This is particularly important because cabling from photovoltaic panels have DC current running through them and are live when it is sunny.”
Resistance Feed-it-Green specified Flexicon’s FPAS non- metallic conduit to protect the cabling on the roof. This provides enhanced UV resistance, good compression strength and when used with the FPA fitting has an IP rating of IP66. The conduit was used with the company’s FPA T- pieces, which provided a neat method for cables to branch off to connect to the individual photovoltaic strings. To enhance the mechanical protection
offered down the side of the building, a coupler was used to connect and convert the FPAS system into a metallic conduit called FSU. As a metallic system, it has excellent mechanical strength to protect it from vandalism or theft. It is also flexible so that it can bend around the eaves. Flexicon has also supplied flexible conduit to
protect all the internal cabling to the inverter and then from the inverter to the distribution boards.
