farmers has an installation | Solar industry well established in the UK – 2GW installed nationally | Module prices 50% lower than 18 months ago | Yields much higher than forecast | EPC costs falling – best time for build is summer | Bigger & bigger solar farms | 50 in planning in Cornwall alone | Banks and pension funds supportive lenders and buyers
Solar included in Renewable Energy Roadmap | Government targets 22GW of solar capacity by 2020 | National Solar Centre opening in Cornwall | ROCs fixed for solar through 2017 – best deal is early
issued for renewable energy (e.g. solar) generated and consumed in the UK | Issued per MWh — 1.7 for rooftop solar / 1.6 for ground-mounted solar — to generators | ROCs are bought by electricity suppliers from generators to meet their ‘renewables obligation’ i.e. 12.4% of electricity supplied (2013) | Lower rates in Northern Ireland than England, Scotland and Wales What are Power Purchase Agreements (PPAs) | Contract between a generator and an energy supplier | Long-term (e.g. 10 year) stable-price contract or variable year-to-year | Average auction value of ROC in 2012: £43.86

Leverage daytime energy demands System consumption: The proportion of solar energy consumed vs. exported = more profitable use Autarky: The proportion of total energy demands that is met by solar System Consumption & Autarky SYSTEM CONSUMPTION Consumed PV kWh (e.g. 1,200 kWh) PV system output (e.g. 3,000 kWh) = 40% High rate of consumption increases profitability of PV system investment (IRR) AUTARKY Self-consumed PV kWh (e.g. 1,200 kWh) Electricity demand (e.g. 4,500 kWh) = 26% High degree of autarky increases absolute earnings / electricity cost savings
