MCT-Hybrid Initial results

• Electrical output 305 W

• Thermal output 1580 W

• >65% Solar Harvest

• High Voltage / Low Current design minimized losses and increases inversion efficiency

• Shipping in 2012

• Won $3.2M Grant in conjunction with the CSIRO, ANU and UNSW to develop high temperature hybrid (150ºC/300ºF)


Shared Integration Cost

Thermal PV Installation

Cost

Technology cost is only 50% of the total system cost so

coupling the installation of PV and Thermal together reduces

the total installed cost ($/W) and ultimately LCOE


Low Temperature Solar Cooling


Day-lighting MCT


Shared Integration Cost

Thermal

Daylighting PV

Integration cost could further be shared with the

installation cost allocated for day-lighting

Chromasun 10MW / Annum San Jose facility


MCT Summary

• Chromasun MCT is based on existing CSP technology and over a decade

of experience in large-scale solar

• Concentrating the sun’s energy enables the MCT to consistently deliver up

to 220ºC (440ºF) on the rooftop

• MCT has no externally moving parts, reducing O&M

• Unlike other concentrating technologies, cleaning is limited to flat glass

(automated cleaning system in development)

• MCT can be turned on a off which provides safe operation

• MCT is a durable, industrial grade product with sturdy installation method

• The delivery of higher grade heat enables compatibility with absorption

chillers and thermally driven heat pumps

• Aperture efficiency will reach 75% by the end of 2011

• Hybrid MCT to be showcased in Q4 2011 (Funding round in Q3/Q4)

• Project financing available through Chromasun
