17 Locations and Irradiation data base for mining Sunbelt key benefits of PV addressing. PV taps into unlimited, indigenous energy supply and can make a sizeable contribution to meet rising power demand PV generates power close to consumption, thus supporting strained grids or enabling local mini grids. It can be combined well with other renewable or conventional technologies. PV can thus accelerate electrification and stimulate economic activity, while reducing import reliance High irradiation levels make PV already competitive compared to diesel generators. In the future, PV will be highly competitive to all alternatives. Directing investment into PV now provides a long term source of energy with low operational cost and enables domestic industry build up PV is a low carbon technology and has an energy packback time of months. It doesn t need water to operate and has no adverse impacts on local air quality October 25, 2012 Slide 17

18 Other consideration to improve PV plants Predictivity and dispatchability Require an evolutionary optimization algorithm based in an Artificial Neural Network used for 24 hours weather forecasting and production estimation. Accuracy must be better than 5%. Storage system required (hydraulic, batteries ) Additional incentives can complement the technology attractiveness (Law 20/20) Job creation. PV is the industry than will generate more local jobs in O&M. Countries with high portion of non-qualified people can employ and qualify this population for basic maintenance (cutting grass, cleaning panels, manual fix structure orientation, painting ) Require an adaptation over the actual O&M criteria (win to win). South Africa criteria: megawatt solar farm (8-10 people) Certified Emission Reduction (CER). The CERs are assigned and approved by United Nations and the beneficiary projects are revised per year. 1 CER = 1 ton CO 2. equivalent (Conversion CER to KWh depends on the host country energy mix) Average price for 2011 was 16 /CER. Estimated demand per year: USA M, EU: 210 M, Japan: 250 M Conversion 1 kwh 0,64 kg of CO 2 (1 c /KWh). In case of industrial trading demand, 3 c /kwh October 25, 2012 Slide 18
