Mr T's 3.87Kwp Array, Smalley
This was an interesting project, the client had decided to extensively remodel his house whilst still living in it. The new two storey extension had a roof that was South facing and nearly 14m long.
We designed a 3.87Kwp array to fit the available foot print. The panels where located in the high pressure areas of the roof, the anchorage loadings where calculated and the appropriate anchors and fastenings chosen. The new roof was designed to accommodate the additional loading of the array.
The Inverter was located in the roof space, thus keeping the DC cables short and separate from the AC cabling.
The new AC circuit was run from the inverter beneath new plaster finishes through an existing roof void into the clients garage.
