  1. Steve Barrett MD of Solarsense

  2. Renewable Energy Options

  3. Solar energy efficiency in the UK: Portishead

  4. Portishead is an ideal location for solar PV

  5. 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!

  6. Portishead is also ideal for: • Wind • Wave • Tide

  7. Examples of investment in renewables...

  8. Island of Eigg

  9. Flatholme

  10. Both these concentrate on wind and sun • Simple to install • Island location; delivery a challenge • Many more options on mainland...

  11. 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

  12. 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

  13. Further challenge: • Mains gas From 2016 no new houses will be connected to the gas main Mandatory requirements: • Super-efficient homes • Renewable energy sources

  14. 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...

  15. Solar Tiles Solar Slates

  16. Complete solar roofs Highgrove Croyde Holiday Cottage

  17. 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

  18. 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

  19. The case for microgen: • Electricity generated where it’s needed... 35% out Only 1% out!

  20. The case for microgen: Power generated where it’s needed!
