Vega — New Approach

Why do We Need to Develop Concentrate Solar Collator?


By concentrate the sunlight to get multi-times irritation level, then to generate high temperature thermal energy to supply industries and manufacture.


But….. why the concentrate solar collector is not widely use now?

Three main reasons:

  1. Too expansive if use current design and technical approach.

For example, One Schott Receiver alone costs a small fortune.

Φ70mm, L=2,000mm market price at USD 1,800.-

  1. they need far too much & ongoing TLC (maintenance), reliability is poor.
  2. Installation is totally nightmare for most of case.


  • 2018 “Worldwide Average” installed cost of CST per kW-th stood at USD 5,204.-. This is indeed a historical low.
  • This translates to AUD $ 7,650.- per installed kW “worldwide average”,
  • and to AUD $ 9,650.- ~ 10,200.- per kW installed, allowing for Australian specific installation costs and other factors, e.g. remote location transport



Average Installation of CSP

Introducing VEGA
a mild concentrating modular, lightweight and truly AFFORDABLE high performance CST , from Greenland Systems

VEGA is a completely novel CST design. It was designed completely “from scratch”, almost nothing is inherited from any of the presently existing CST.


Vega is unique among concentrating & tracking collectors in that it does not employ movable hydraulic lines.

Maintenance of hydraulic lines on conventional concentrators accounts for about 40% of all maintenance. Getting rid of these was important

  • Vega is designed to be volume produced and to be installed fast by a very small installation crew
  • Vega is a lightweight, cost-effective CST. A BONUS: it can be installed on most factory roofs
  • Heat from the absorber is effectively transferred to the Heated Fluid in a patented highly turbulent Heat Transfer Chamber at an extremely low pressure and temperature loss
  • Vega does not need any expansion bellows. EBs are a well known Achilles’ Heel in old CSTs
  • Solar Working fluid is separated from the heated fluid. Absorber is freeze proof without using antifreeze
  • Vega can be used to heat a wide variety of fluids, including air 18
  • Cost of a replacement vacuum tube is about $ 100.-, rather than several 1,000 $
