2. Innovations and boarder conditions
Outline
Technology potential vs. Grid Potential
Utility scale vs. Residential scale
HVAC vs. LVDC
Domenico Sartore - GIFI's Member - Milan, 24 / 2 / 2010
3. Innovations and boarder conditions
New Techs In Italy
Many PV start-ups
R&D activities: CPV, CdTe, micro-
crystalline Si, Multi-junctions,...
Program “Industria 2015”: 25% funds
requests for PV research
Domenico Sartore - GIFI's Member - Milan, 24 / 2 / 2010
4. Innovations and boarder conditions
Thin-film is still an option?
For very large PV system the price gap
between thin-films and c-Si is reducing
For very large PV system low efficiency
is a drawback
Silicon constitutes the 25% of the Earth
surface

5. Innovations and boarder conditions
… but where is the limit?
Currently we need realistic and
sustainable development projects
because of GRID LIMITATIONS and
REGULATIONS
Domenico Sartore - GIFI's Member - Milan, 24 / 2 / 2010
6. Innovations and boarder conditions
A possible scenario
Low cost CPV (made in Italy) system:
turn-key price 2 €/Wp
Good irradiation site with available
“brown-fields”: Sicilia or Puglia
No grid connection due to a 60 years
old electrical line
Domenico Sartore - GIFI's Member - Milan, 24 / 2 / 2010
7. Innovations and boarder conditions
What do we need?
Investments in the grid (even not
smart!)
A unique national rule for very large
system (Autorizzazione Unica)

8. Innovations and boarder conditions
The other half of the sky...
Energy storage system can
dramatically contribute to PV deployment
The new goal: have a predictable PV
power source
Domenico Sartore - GIFI's Member - Milan, 24 / 2 / 2010
9. Innovations and boarder conditions
Residential first
With a “new” storage system it is
possible to modify our vision of small
residential system
Stand-alone become the optimal
solution to avoid regulations and grid limits
Domenico Sartore - GIFI's Member - Milan, 24 / 2 / 2010
10. Innovations and boarder conditions
Back to the future
Why do we have to loose energy in the
AC/DC conversion in our houses
(transformers everywhere) when the PV
current is DC … and our laptop is DC?
No inverter, 110 V are enough, no
AC/DC losses
Domenico Sartore - GIFI's Member - Milan, 24 / 2 / 2010
11. Innovations and boarder conditions
LVDC grid
Residential LVDC grid or minigrids will
reduce the cost of/for electricity for the
final consumer: this step will remove all
the barriers to create a new energy era.
The PV Era.
Domenico Sartore - GIFI's Member - Milan, 24 / 2 / 2010
12. Innovations and boarder conditions
HVAC grid... or HVDC
HVAC could be necessary to permit the
distribution of the energy... but... why not
HVDC?
HVDC is better than HVAC with power
> 1000 MW and distance > 700 km
Domenico Sartore - GIFI's Member - Milan, 24 / 2 / 2010
13. Innovations and boarder conditions
How GIFI promotes the
innovations
In the 2011 version of the “Conto
Energia” with 2 main initiatives
1) FiT for CPVs
2) FiT prize for programmable PV plants
