Ideal Solar

Ideal has always been at the forefront

of developing systems to reduce energy

consumption, leading the change to

highly efficient condensing boilers in

the 1980s. Now Ideal Solar offers a

simple way to harness Solar energy,

to reduce carbon emissions and

energy bills.

Solar energy can be readily obtained

whether the day is bright sunlight or

even when cloudy. Solar collectors

absorb the sun's rays and convert that

energy to produce hot water in the

home. They supplement the normal

hot water storage system and in

summer will provide most of the HW

needs. Even in winter boiler usage will

be reduced. Overall a solar system

reduces carbon emissions and our

impact on our environment.

The technology is straightforward and

readily understood. It offers one of the

most simple ways to reduce energy

bills using renewable energy. Ideal has

engineered a high quality solar

package aimed at ease of selection,

simplicity of installation and combined

with full technical support, training and

design service (if eligible).

Solar water heating
system

A solar thermal system comprises four

main elements to generate heat, control

and store it. A simple loop circuit

transfers heat from the panels to a twin

coil solar hot water storage cylinder.

The solar panels are connected to the

lower coil whilst the upper cylinder coil

is supplied by the heating boiler as a

normal system. A schematic diagram

shows a typical layout for a house:

As the climate changes and fossil fuels
deplete, it makes sense to harness
solar energy now.

Solar Panel

The solar panels generate heat and are

roof mounted to obtain maximum

energy from the sun. The number of

panels is determined by the size of

household, and the average UK house

will use two. A solar panel consists of

an array of copper tubes between

headers and contains the system fluid.

Each tube is ultrasonically welded to an

absorber plate which has a selective

coating to enhance energy absorption.

The array is sealed into an aluminium

casing with dense insulation at the rear

to minimise energy losses, and a low

iron, tempered glass at front. The glass

is chosen to allow maximum energy

through to the absorber but to be

extremely robust. It is also self cleaning

for long term benefits.

The solar fluid is circulated by the

Pump Station to the lower coil of a twin

coil storage cylinder where it transfers

heat to the stored Hot Water contained

in the cylinder ready for use. It is then

pumped back to the solar panel to be

heated again and so the cycle

continues.

Pump Station

This consists of a variable speed pump

together with flow meter to set the

system flow rate. Check valves with flow

and return thermometers provide easy

use. As the solar circuit is a sealed

system, the required pressure relief

valve and gauge is provided here.

This forms a pre insulated package

for neatness and speedy installation.

The expansion vessel is also fitted at

this point.

Solar Controller

The controller provides the temperature

selection setting for the cylinder and

uses two temperature sensors to

determine when the pump is run to

gain solar energy from the panels. The

solar panel temperature must always

be more than 4ºC greater than the

cylinder before the controller allows the

pump to run. An animated display

shows system operation with system

temperatures.

Orientation

The heat generated from solar panels is

maximised when the panel is sited to

face south. Good solar savings are still

obtained when panels are at an angle

to due south as the following diagram

shows. For the average UK installation

mounting at approximately 30-45

degrees to horizontal is satisfactory.

Energy Performance

Even on cloudy days diffuse radiation

can be captured by the solar panels,

so that energy is obtained even in

winter. During the summer months,

with both direct and diffuse radiation,

it is possible that all hot water energy

needs can be obtained. Averaged out

over the year around 50-60% of a

typical households needs can be

provided by a solar system. The benefit

is dependent on orientation, angle,

latitude and shading.

Roof mounting

A range of mounting systems allow

panels to be fitted in the most

appropriate manner for the property.

- Standard supply allows mounting

on a pitched roof, with optional fixing

arrangements for different roof

coverings. For neater installations,

optional inset mounting kits can

be used.

- Flat Roof frame kits allow solar panel

installation where roof pitch or

orientation is not suitable.
