Solar PV – Electricityfrom the Sun• It is a proven technology – in the rightlocation• Low efficiency (~10%) and low energyoutput• Works best where it’s sunny• Not financially viable in UK withoutNIROCs (typical payback of 60+ years)
Solar PV – is it right for your site?• Do you have rood space?• ~£1,600 per kW• 14 year payback without NIROCs• 6.1 year payback with NIROC’s
Solar Water Heating• Slightly more effective than PV• Can be effective in the right circumstances• High capital costs compared to returns• Can not be considered as a primarysource of hot water.• Benefits from RHI support
Solar Water Heating – Right foryour site?• Available Roof Space?• DHW demand?• £500 per m2 of panel• ~£10-12 saving per m2 per year withoutRHI – 42 year payback• ~£30 saving per m2 per year with RHI (upto 200 kWth output) – 17 year payback
Biomass Heating – is itsuitable for your site• How do you currently heat (oil, gas,electricity)?• Can be very attractive compared toelectricity or oil• Tried and tested technology• Can often be integrated with existingsystems.
Biomass Heating – is itsuitable for your site• Requires a lot of space, particularly for fuelstorage.• Most suited to predictable constant loads –good for meeting a heating baseload• Generally works best in tandem with oil orgas heating• Benefits from RHI support
Hydro Electricity• Again, a tried and tested technology• Can be very predictable in terms of output• Highly dependant on site conditions• Capital costs can be high• Well supported by NIROC’s
Hydro Electricity – anopportunity for you?• Is there a water source on your site?• Is there a drop in height (head)?• Is there space to exploit it?If the answer to all of the above is yes, thenperhaps Hydro is worth exploring further.
Geothermal and Heat Pumps• High capital costs for relatively low returns• May be cost effective where excavation isbeing carried out• Unlikely to be suitable as a primary heatsource• Paybacks typically 15+ years
