7 AHK, Deutsch-Spanische Fachtagung, Gran Canaria Solar energy for self-consumption pays off Comparison of electricity costs on Canary Islands Increasing trend Implementing solar energy in your business EUR Cent / kwh Industrial electricity, on-grid 1) Increasing trend Stable Diesel generators 2) Solar PV 3)! sinks operating expenses! provides energy security! increases planning dependability! creates greater independence! protects the environment 1) Without taxes, AHK Market Study, ) only diesel costs considered: 0.83 EUR/Liter 3) Calculated using LCOE method (Levelized Costs of Electricity) including all costs over 20 years lifetime (CAPEX, OPEX, capital costs) 7

100% PV self-consumption or surplus PV electricity injected into grid (net-metering, feed-in tariff)!

8 AHK, Deutsch-Spanische Fachtagung, Gran Canaria The solution direct generation of solar power for self-consumption! Use of roofs or land for PV power plants! Direct use of solar energy for own demand! PV runs together with grid! 100% PV self-consumption or surplus PV electricity injected into grid (net-metering, feed-in tariff)! Self-consumed solar electricity reduces energy bill! Commercial/ industrial energy demand takes place mainly at daytime! High correlation with solar energy profile Reduce your operating costs 8
