GRID-CONNECTED SOLAR ELECTRIC SYSTEMS
Solar electric (Photovoltaic
or PV) systems produce electricity according to the amount of sunlight that
falls on their surface, For this reason unshaded, preferably
south-facing, surfaces are best. The pitched roofs of most houses in
the UK are ideal. Flat roofs can be utilised by fitting a frame to
hold the PV modules.
Output will be reduced by
shade or non-optimal orientations or tilt angles.
|
The average annual
electricity consumption of a household of 4 in the UK is 3500-4000 kWh
per year (3.5 to 4 MWh/year) |
|
A
1 kWp grid-connected PV system in the UK will produce about 700- 800
kWh of electricity per year and require about 8 m2 of
roof area. |
|
A
5 kWp grid-connected PV system in the UK will produce about 3500-
4000 kWh of electricity per year and require about 40
m2 of roof area. |
HOW TO CHOOSE A GRIDPOWER
SYSTEM
Choose Solar PV modules from SCHUCO,SHARP,SCHOTT,
KYOCERA,
SANYO and so on.
*PV
Panel types can be
found here.
Select
Mounting system : On-roof,
In-roof or Flat-roof /ground mounted.
Select PV panel arrangement for your
roof (eg. 2 rows of 8 in
portrait layout)
**For greater output per sq. metre
consider installing panels on
PV TRACKERS.
Select Roof
brackets: Tile, Slate or Metal roof.
Choose the correct PowerOne, Diehl, SMA,
Steca or Fronius
grid tie inverter.
Choose
Data communication
and monitoring
Buy AC side and DC
side isolators
Choose the correct Meter
(eg. Single Phase kWh Meter Elster
A100C)
Choose the
correct diameter and reel length of Solar
cable
Buy the correct
connectors
