4 Global PV Market - Trends 2012 (Sources: IEA PVPS, EPIA, BSW) EU 1 st PV 2 nd Wind TOP 3 PV Germany China Italy Annual growth 29 GW Global Capacity 100 GW Highest growth Asia +66% Annual installations in MW ROW: Rest of the World, MEA: Middle East and Africa, APAC: Asia Pacific

5 Country ranking by cumulative capacity (Source: IEA PVPS ) Installed PV total capacity (MWp) Rank 13 (with IEA GW) 13 countries > 1 GW

6 Massive PV system price reduction (Source: BSW, PV-Exchange 2012, own calculations) Cost reduction to 1/3 in last 6 years (340 INR to 119 INR / Wp) LCOE decrease 16 INR to 7 INR / kwh (LCOE over 20 CUF 15%) Still huge differences in country specific prices (especially residential) German System prices for <= 10 kw based on PV- Exchange Index EPIA scenario for residential Segment in the EU at 1.30 Eur/Wp (88 INR) in 2022 (119 INR)

7 Global PV Trends 2012 Summary & Conclusions 100 GWp capacity exceeded worldwide First drop in EU PV Growth within last 10 yrs / ever System costs reduced to 1/3 within last 6 yrs 13 countries entered the GW capacity class (9 further are close) PV will play a key role in the global electricity mix

9 Why is Germany pushing the pedal? The energy transition 80% RE 2050 & nuclear phase out until 2022 in order to: Fight climate change Reduce energy imports Stimulate innovation & green economy Strengthen energy security & local economy More:

10 German PV Market 2012 (Source: BSW-Solar) By : Total installed capacity: 32,400 MWp Number of grid connected PV systems: 1,280,000 PV Target = maximum subsidised capacity = 52 GW by 2020 anual installed capacity 10

11 Rooftop Ground Mounted Building integrated PV market segments in Germany <1% Image: Grammer Market share of Image: installed Sharp capacity in % Image: Geosol Private buildings: 1-10 kwp Social, commercial, agricultural buidlings: kwp Large commercial buildings: > 100 kwp 10% 38% 23% 71% Image : Solarwatt Image : Solarwatt Image : BP Source: BSW-Solar, E.Quadrat GmbH

12 Grid connection (Sources: Badenova, RENI / Solarpraxis) <1% 15% 85% Share of RE Systems connected to grid of Badenova From top-down structure to fluctuating bi-directional power flow Distribution grid becomes collector grid Distributed PV has main impact on LV distribution grid

13 Typical German FIT Single line / scheme (Picture Source: Agentur fuer Erneuerbare Energien) DC Switch / Junction Box Grid-tied Inverter Unidirectional Meter Feed-in Connection at Distribution board Unidirectional Meter Consumption Inverter will switch off when grid is off spec Solutions for captive supply now ramping up (e.g. new storage law) Applicable EEG FIT as of 1 st May (for 20 years) Up to 10 kwp 40 kwp 1 MWp 10 MWp Eur/cent INR

14 Germany PV Market - Conclusions 1. Distributed PV is a success model Potential alone for dark Germany: 203 GW (following calculations of Prof. Drg. Ing. Volker Quaschning HTW Berlin) 2. Grid Integration is possible without problems Proven with 32 GWp in more than 1.2 Mio Systems on the grid 3. Solar PV is economical feasible & competitive today Storage is the next big issue coming up

16 Net Metering vs. Interconnection (Source: Freeing the grid 2011 / IREC) Interconnection: The technical rules and procedures allowing customers to plug in to the grid. Net Metering: The billing arrangement by which customers realize savings from their systems where 1 kwh generated by the customer has the exact same value as 1 kwh consumed by the customer

17 Classical Net Metering (NME) - model As implemented e.g. in the USA: The grid feed-in energy will be set off with grid supplied energy. Produced electricity. consumed: difference supplied by grid billing of supply Produced electricity. consumed: excess feed to grid offset with bill / kwh banking Different regulations from state to state for: Time of day tariffs, monthly roll over of credits, limitation of excess, power limits, etc.

18 Net Metering Basic economics Basic assumptions for small model calculation: PV costs per kwh = 7 INR LCOE 20 yrs Levelized Costs of Electricity very simplified: LCOE = Total life cycle costs Total Lifetime Energy Production 7 INR / kwh over 20 yrs for operation & total payback considering investment costs of 100 INR / Wp and average Indian CuF Grid Costs per kwh = 6.50 / kwh As per my electricity bill yesterday (New Delhi, BSES not including all charges) Annual, linear Inflation of 8%

19 INR / kwh Net Metering Basic economics II PV LCOE Grid Supply Margin / Savings INR / kwh Year of Operation Cumulated savings for a 2 kwp 1600 kwh/kwp Amortisation & Operation 10 yrs: 77, yrs: 5,03, Added value of independent power supply (all calculations without considering subsidies)
