All the things we and work on DC
WHY SO
DC is more Energy Efficient
DC uses less Raw Materials
DC: Communication as a standard, no feature
DC Grids are Smart(er) Grids

WHY NOT
DC: ‘new’ v.s. “vested interest”
DC: (more) dangerous!?
Dilemma: trust in electronics for your safety?
AC will enable Smart Grids as well

Together with DC-technologies, it will
Offer a better energy efficiency
Offer ‘Smartness’ as standard
Offer both Electrical and Thermal Grid control
Locally stored warm water supply

FOR YOUR CONSIDERATION
PV installations
Panel orientation East – West
Gradient of panels 15° to 20°
Use more locally generated electricity
Preventing expensive storage
Grid connection / DNO - DSO
Controllability enables new business models
Internet-connectivity: fixed rate for capacity
