Agenda Solar Thermal - General Principles Understanding Role of Resource Availability Solar Thermal Markets About Megawatt Solutions Private Limited
GENERIC PRINCIPLES
CST- Basic Principles
Basic Principles Design and Costing m2/kwth Power Block Overheads * $/m2 kwe $ = $/kwth kwth/kwe = $/kwe (SF) = $/kwe (PB) = $/kwe (OH) Project Cost
Basic Principles Solar Field Output True Direct Normal Insolation (W/m2) Ambient Temperature Required Outlet Parameters (T/P/F) Technology Response to True DNI with Temp Technology Response to Outlet Parameters Instantaneous Output (kwth/m2) Annual Input Profile (Hrs/year) Cummulative Yield (MWh) Concentration Ratio Solar Tracking Geometry Loss How Effectively Can System Utilize Wide Range Of Radiation (200-1000 W/m2)? What percentage of year Will System Perform At Max, Min, Avg Efficiency? How sensitive is the system to tolerances?
Energy Yield Comparisons For Technologies

RESOURCE AVAILABILITY
Solar IRRadiation Data Is a Critical Metric To Determine Project Feasibility IRR adiation Data Is the Most Critical Parameter that directly impacts Capital Costs O&M Costs Return On Investment Bankability Life Of Plant & Future Cash Flows Critical Resource Availability analogous to Coal Linkage Studies Engineering & Scientific Assessment (Correlation Models, E_dump) Sensitivity of Returns In a Generation Based Incentive regime
Understanding DNI Profiling
IRRadiation is Critical in Indian Context
Bankable Irradiation Datasets Are Key To Success of Solar Thermal
