They range in size from a few square centimetres, for example on
calculators and watches to systems hundreds of square metres made
from interconnected modules that form an array.
When exposed to
daylight, electrons in the semi-conducting material become
energised. These electrons are then able to flow through the
material generating a direct current (DC). The DC is carried through
wiring to an inverter which converts the current to 240V alternating
current (AC) so it can be connected to your home’s main electricity
supply.
Most homes in Scotland are suitable for PV Panels. To maximize the
potential of your system which is linked to the financial gain, the
panels should be facing in a southerly direction. Shading of more
than 20% by trees, chimneys, dormers and other buildings will affect
their performance.
Scotland (Tayside) receives approximately 997kWh/m2 of solar
radiation and benefits from long summer days, giving more daylight
to generate your electricity. |
