Steve Barrett

MD of Solarsense





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!







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...


Solar Tiles

Solar Slates


Complete solar roofs

Highgrove

Croyde Holiday Cottage


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!
