Solar PV Case Studies

Project: New Build Solar PV and Thermal Installation (Schuco Installation)

Location: Isle of Man

Type of Property/Building: New detached eco house

Technology Solution: Solar PV and Thermal


The requirement was for a complete solar roof that needed to be totally integrated with the new development. A complete set of bespoke engineered roof flashings were designed and integrated with the proposed roof and glass atrium. This provided a totally sealed solar PV and thermal roof for the building.

Solar PV Panel Configuration:

Number of PV Panels: 41 Panels
Output of each PV Panel: 320 Watts
Weight of each PV Panel: 49 Kg
Area of Panels: 110 Square Metres
Peak Output: 13.12kW peak
Type of roof kit: Complete roof, landscape orientation
Type of system: Grid connected


Energy Generated Per Annum (estimated): 10.94 MW hours
Annual Saving in CO2 Emissions (estimated): 4702 Kg
Annual Saving in CO2 Emissions (estimated): 4.7 Tonnes



Solar home, Barnes, South West London (Solarcentury Installation)

In June 2007 landlord Chris Hill had C21e solar electric roof tiles installed on his rental property in Barnes, south west London. C21e tiles replace normal roofing tiles, generating free and green electricity without altering the roof line of the house.

Chris chose to install solar roof tiles because 'reducing my carbon footprint is very important to me. I needed to re-roof the house, and it made sense to use solar roof tiles as opposed to regular tiles. The tiles from Solarcentury are well integrated, and seemed more efficient than other solar panels.' He added, 'Secondary to this was 'future proofing' the house against rising fuel prices, making it cost less to live in and hence more attractive to tenants. I would recommend it to others looking to improve the appeal of their properties as solar tiles have proved a simple, cost effective and innovative way to improve a home.'
Chris' system is 1.66 kWp in size, which means it can generate up to 1,411 kWh per year. According to the Energy Savings Trust, the average household consumes around 4,000 kWh per year, so even a small system like Chris' can cut consumption from the grid and therefore utility bills by almost 30%. By January 2009, the home had generated a total of 2,171 kWh. The tenants can sell their electricity back at between 15 and 20 pence per unit depending on their supplier. Chris can also claim over £100 a year in Renewable Obligation Certificates (known as ROCs).

Bex Cooper and her partner Ian Thurston, Chris' tenants, were already living in Chris' property when the tiles were installed. They say that they were always conscious of their energy consumption, 'using as little as possible for both planet and purse' so they were delighted when their landlord installed the solar tiles. Even taking into account the couple's already responsible lifestyle, Ian says they have seen a
'big drop' in their energy bills and are receiving cheques from their electricity supplier for the energy they generate. A big bonus when everyone else's prices are going up!
