PV power plant 101 – As simple as …

Grid PV string PV arrays Inverter Step up transformer Main transformer DC AC

System efficiency (Performance Ratio or PR) = kWh to grid / (Plane of array irradiance x module efficiency)

Figures from a large scale PV power plant A typical 50MW dc solar PV power plant could have

~200,000 PV modules
~10,000 strings
~ 600 dc combiner boxes
~ 50 x 1MW inverters/inverter houses and step up transformers
~ 3000 tons of steel structure
Up to 50,000 foundations
~ 90km of power cables
~ 90 hectares of land
~100,000 man-days to completion

Utility scale solar projects

picks up in less than 10 years because of regulatory support,

price reduction and market maturity

achieves low cost from economics of scale
electrically simple but the volume needs attention
unique challenges include footprint, resources intermittence,

quality control and performance monitoring

benefits HK in terms of knowledge/skills and equipment

supplies Conclusion
