PV Uses a network of solar cells, made of silicon, which are linked together to form a panel

Panels can be sized or linked together to meet specific energy requirements

When sunlight shines on the panels an electrical field is created across the cells

This allows an electrical current to flow through the layers of cells

The greater the intensity of light, the greater the flow of electricity


The result is Direct Current (DC) electricity, which is passed to an ‘inverter’

The inverter changes the DC into Alternating Current (AC) electricity

AC is what we use everyday as mains electricity

The inverter then supplies this usable AC power to us through the fuse board

If the energy created is less than required the remainder is drawn from the national grid, helping to keep your energy bills low

If the energy created is more than required it could be exported to the national grid, potentially earning you incentive payments.

Alternatively, battery storage systems can be used to store excess energy for use at a later time, rather than releasing it to the national grid

Solar Thermal

Solar thermal heating systems harvest solar energy by absorbing the suns energy through a ‘collector’ and converting it to heat. Collectors come in a wide range, and each have different purposes and temperatures.

AES Solar manufacture ‘flat plate collectors’, consisting of a metal ‘absorber’ housed in an insulated box with a transparent cover to allow sunlight to enter.

Absorbers are usually made with a highly conductive metal with a special coating to maximise the light absorbed and converted to heat.

Heat collected by the panel is transferred to a specialised heat transfer fluid The heat transfer fluid circulates within a solar loop linking the solar collector to a ‘heat exchanger’, typically a coil in a cylinder

As cold water enters the cylinder it absorbs heat from the copper coil and exits as hot water, ready for central heating, washing, bathing etc.
