COST & ENERGY EFFICIENT PV INVERTERS
Panel level electronics
Safer systems
More energy
Easy installation
Lower cost
Next-generation PV Inverters
•
Solar PV inverters convert DC (from panels) into AC (for the power grid)
Optistring PV inverters:
1. Take a game changing, cost efficient, distributed (panel level) approach
2. Are high efficiency, safety-compliant and cost ½ to ¼ of competitors’ alternatives
3. Enable positive business model change for large panel manufacturers
4. Fits the market trend (rooftop, safety …) and panel manufacturers’ downstream push
5. Will drive module level electronics penetration beyond current projections
Optistring status:
• Joint development with a major global panel manufacturer
• Finalising contract manufacturing partners
• Pilot installations

Todays solution
The solar cells are soldered together to strings.
This is usually done in a Tabber/Stringer
(automated solder machine).

Solutions for
Solar Parks
 High system efficiency yielding the most energy efficient approach
to converting solar power into electricity
 Cleanergy's Stirling CSP system produces electricity below
grid-parity cost levels given initial 200MW sales volume
 Mounted to reflective parabolic dishes which tracks the sun
from morning to evening providing high and sustained
power production
 Offering maximum solar power extraction per square
meter compared with traditional CSP systems, 100%
clean energy is produced at peak efficiency from
sunrise to sunset
 Cleanergy has developed pioneering and
proprietary system and park software optimizing
system performance
 Technology repeatedly verified by several
independent authorities

performance (Ordos)
Observed DNI Ordos
 Already at DNI of 830 W/m2, Cleanergy’s Stirling engine
is producing at its peak power rating of 10 kW
 The oversized dish in combination with system
improvements explain the improved system performance
 Continous monitoring of park performance gauges power
production
Output Power at or above
the Peak Power rating
(Tot. time >7h)
 Cleanergy’s Stirling CSP system power output is currently capped
at 11kW
 Observations conclude that on a cloud free day with a DNI of >900
W/m2, the system outperforms its Peak Power Rating by 10 %
 Production at or above Peak Power Rating is achieved in excess
of 7 hours from the system tracking the sun from morning to
evening

Industrial
production capacity
 Cleanergy acquired the former manufacturing plant of Volvo Cars
in western Sweden
 Industrial capacity is hereby matched for increasing demand.
The assembly plant, situated in the world-class Northern
European automotive cluster of western Sweden, provides
ideal conditions for collaboration with advanced component
suppliers at close geographic proximity
 Access to highly skilled employees
 Using state-of-the-art manufacturing techniques and
material technology, the current industrial
production capacity allows the company to quickly
adapt to increasing demand
 Current production capacity amounts to
22,500 units per year (~300 MW) which can
be extended even further at low cost
