Solar PV


How does Solar PV work?


What is Solar Pv full diagram of house with solar panels instaled and how it generates solar powerSolar PV systems convert light into electrical power using a thin layer of semi-conducting material, usually silicon, encased between a sheet of glass and a polymer resin.  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.

Solar PV panels are incredibly durable and can easily withstand temperature variations and humidity.


Solar Pv: Positioning


The Solar PV panels on your roof should face in a southern direction to receive the maximum amount of sunlight during the day. Although the panels are most efficient when facing south they are still very effective when east and west facing.

Avoid placing the panels where there will be substantial shading from nearby trees or buildings, as this will reduce the output from the system.Our installers will work with you when planning the installation to avoid shading wherever possible.

The pitch or angle of your roof can make a difference to the amount of sunlight it will receive throughout the day, for maximum output your roof should be between 30-40 degrees, thus increasing the amount of energy that can be produced.

In the UK we receive about 60% of the sunlight from the equator due to the UK being about 56 degrees on the axis of the earth.
