Solar (PV) Panels What are they and how do they work? – Solar Power fed back to the grid & used at the property Benefits – Qualifies for FIT Costs
Solar Thermal Panels What are they and how do they work? – Solar heating pumped via insulated tank – Heat water for minimal cost Benefits – Qualifies for RHPP Costs
Heat Pumps What are they and how do they work? Types – Air Source – Ground Source – Vertical & Horizontal – Water Source Benefits – RHI & RHPP Costs
Wind Turbines What are they and how do they work? Types Vertical & Horizontal Benefits – FIT Costs
Biomass Boilers Want are they and how do they work? – Generate renewable heat Types – pellets, shavings & logs Benefits – RHI & RHPP Costs
Mini Hydro What is it and how does it work? Bespoke dependant on case Benefits – Virtually constant power source Costs
Rainwater Harvesting What is it and how does it work? – Rainwater is reused and treated for either potable or grey water use Benefits Costs
Feed In Tariff (FIT)Typical Example Of Benefits With 20 kWp Solar PV System: A. Generation income Tariff 13.03p per kWh x Annual generation 18,000 kWh = £ 2,345.40 B. Export income Earn 4.5p x (estimated at 50% of generated amount) kWh = £ 405 C. Fuel bill savings Save 10p per kWh x 17,000 kWh = £ 1,700 Total system benefit per year A + B + C = £ 4,450.40
Solar (PV) Panels Typical Investment & Payback 20 kWp Solar PV System Installation cost (£ 32,000) / Annual benefit (£ 4,450.40) = 7.2 year payback on investment The Feed In Tariff lasts for 20 years & all calculations are made without inflation adjustment (which will be made) and increased imported electricity costs. Therefore the benefit total is likely to be considerably more.
Government IncentivesAvailable Feed In Tariff (FIT) – Available to all Renewable Heat Incentive (RHI) – Available to commercial Renewable Heat Premium Payments – Available to domestic prior to RHI roll out this summer Enhanced Capital Allowance (ECA) – 100% of investment written off in year 1
Other Incentives Independent Low Interest Loan Siemens Financial Services (SFS) (Previously run by Carbon Trust) – No capital outlay – No additional outgoings (Savings made pay for the installation)
