Steve Barrett

MD of Solarsense

slide6

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!
slide13

Both these concentrate on wind and sun

  • Simple to install
  • Island location; delivery a challenge
  • Many more options on mainland...
slide14

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
slide15

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

slide16

Further challenge:

  • Mains gas

From 2016 no new houses will be connected to the gas main

Mandatory requirements:

  • Super-efficient homes
  • Renewable energy sources
slide17

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...
slide18

Solar Tiles

Solar Slates

slide19

Complete solar roofs

Highgrove

Croyde Holiday Cottage

slide20

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

slide21

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
slide22

The case for microgen:

  • Electricity generated where it’s needed...

35% out

Only 1% out!
