This high efficiency PV technology allows Suntech to achieve conversion efficiency rates in the range of 18% to 19% on PVcells manufactured with monocrystalline silicon wafers and 16.5% to 17.5% on PVcells manufactured with multicrystalline silicon wafers.
Eligible improvements (PDF) include not only energy-saving equipment such as insulation, lighting, and HVAC systems but onsite renewable energy (rooftop PV, wind turbines, and fuel cells) and water-saving upgrades such as low-flow plumbing fixtures and grey water systems.
