Steve Barrett MD of Solarsense
Solar energy efficiency in the UK: Portishead
Portishead is an ideal location for solar PV
Why so much better? • High UV • Low pollution levels • Cooler summers • Performance as good as Spain owing to temperature • Because of significant drop-off above 30°C • Only one day a year in Portishead!
Portishead is also ideal for: • Wind • Wave • Tide
Both these concentrate on wind and sun • Simple to install • Island location; delivery a challenge • Many more options on mainland...
Primary challenge with renewables: • Free energy after installation • Significant up-front cost Government incentives to help with this: • Feed-in Tariff for PV • Paid for ALL the electricity you generate • And you benefit from free electricity • From April 2014 – Renewable Heat Incentive (RHI) • Paid for offsetting fossil fuels with renewables • Typical pay-back of 5-7 years • Ongoing savings from reduced energy bills
Examples of renewables: • Biomass (pellet) boilers • Suitable for older properties with average insulation • Heat pumps • Suitable for modern, well insulated properties • Solar thermal for hot water Commercial Biomass Domestic Biomass
Further challenge: • Mains gas From 2016 no new houses will be connected to the gas main Mandatory requirements: • Super-efficient homes • Renewable energy sources
The future: • PV is simple and inexpensive to install • Efficient and maintenance free • Solarsense panels – low ‘carbon footprint’ • Manufactured in Sweden using hydroelectricity • Discreet PV systems available...

The future: • Low energy lighting • Battery storage – for electricity at night • Heat pumps • Extract energy from air or ground • 1kW of electricity produces 3kW heat • Electric vehicles • When do you have time to charge a car? • Most cars stand idle for 80% of the day Kendleston Manor
Community: • “Power Parks” • Sun or wind • Typical investment of £250 to £5,000 • Guaranteed return of 5-8% for 20 years • Biomass • Area heating schemes • Blocks of flats or entire streets
The case for microgen: • Electricity generated where it’s needed... 35% out Only 1% out!
