C21e for housing developers
Incorporating C21e tiles into new housing developments offers many benefits for the developer.
Improve your chances of gaining planning permission
Incorporating C21e solar tiles helps developers gain planning permission by reducing the carbon dioxide emissions from their developments. As planning rules strengthen, the use of renewable technology is becoming a prerequisite for every building developer in the country.
Most UK Local Authorities are redrafting their Local Development Frameworks (LDFs) to comply with Central Government guidelines (Planning Policy Statement 22) and demanding that all new developments, over a certain size, provide a proportion of their energy from on-site renewables.
(see www.TheMertonRule.org
).
Incorporating C21e helps ‘fast track’ planning applications.
Simple, standardised installation
C21e is an advanced solar solution that has been designed specifically to avoid the complications associated with conventional ‘bolt on’ solar panels. The tiles sit flush with the roof avoiding any change to roof layout and are quickly and easily fitted by the roofing contractor. All plumbing and electrical work is undertaken at the usual time in the build program by the existing contractors. There is no need to compromise the design or aesthetic of the house, or the standard build programme.
Publicity and Sustainability
Incorporating C21e into a project presents several opportunities for developers to promote their commitments to sustainability. Eco-measures, such as solar tiles, and carbon reduction initiatives are extremely topical and generate significant publicity.
Pro-active developers can gain significant marketing advantage and media exposure by emphasising their contributions to the UK’s C02 reduction target (reducing emissions by 10% by 2010) through the incorporation of renewable energy technology.
As fuel prices rise and renewable energy moves up the political and media agenda, house buyers are becoming increasingly interested in sustainability measures. C21e can play an important part in a developer’s marketing strategy.
C21e - Key Features
- No extra planning - no need to alter roof lines, colour or pitch. C21e tiles sit flush with conventional roof tiles.
- Standard installation - tiles fit with conventional roofing practice without the need to adjust battens. One solar tile takes the place of four standard tiles.
- No specialist skills - all roofing work is carried out by the roofing contractor allowing electrical and plumbing work to follow build programme.
- Fast to fit - tiles are integrated in exactly the same way as conventional interlocking tiles.
- High power output - 52Wp per tile, less than 8 square metres per kWp (kilowatt peak).
- Discrete ‘SunPower’ PV laminate - blends superbly with regular roof tiles offering an unrivalled aesthetic.
- Back mounted contact strips - increase effective collector area and reduce surface glare, typical with standard solar cell technology.
- Integrated ‘thru-flow’ ventilation - enhances PV performance.
- Power output - guaranteed for 20 years from date of commissioning.
- No electrical work required on roof - avoiding delays to the build programme.
- Tiles arrive on site as complete units - avoiding the need for on-roof assembly.
System sizing
The modular nature of the C21e design provides the opportunity to select the appropriate number of C21e tiles to meet the energy generation required for each home.
As an example, 30 C21e tiles would provide approximately a third of the electricity demand for a typical 3-bedroom home.
