Of The FUTURE


2/38

Solar energy ,a radiant light and heat formthe sun has been harnessed by humans since

Ancient times using a range of ever evolvingTechnologies

Solar Technologies include

Solar Heating,

Solar Photovoltaics,

Solar Thermal Electricity, and

Solar Architecture ...

Which can make considerable contributions tosolving some of the most urgent problems in theworld now faces.


3/38

There are Two types of Solar energyutilization,

They are:-

ACTIVE Solar Energy

PASSIVE Solar Energy


4/38

Solar Energy

Passive Solar sunlight used to light, heat

and cool a building.

Active Solar a system of solar collectors

used to create electricity or heat a building.


5/38

Active Solar Technology is employed toconvert Solar energy into another more usefulform of energy by suing Electrical or

Mechanical equipment for this conversion .

Solar energy collection and utilization systemsthat donnot use external energy


6/38

Passive Solar Technology is used in windows wallsand floors are made to collect ,store and distribute

sloar enegy in the form of hest in winter and rejectsloar heat in the summer

It does not use any Electrical or Mechnaicalequipments.

Size of the Sun=696,000 Km

Distance from Sun to Earth =149,476,000 Km

The Ammount of incident Solar energy onEarth each year is

=160times the worlds proven resources offossil fuels

=1,500 times the worlds Annual energy use

DEFNITION

Collection, storage, distribution and control ofenergy flow by natural processes of heat andmass transfer

WORKING DEFINITIONUse natural energy (sun, wind, etc.) to

conserve conventional energy for achieving

thermal comfortThermal comfortrefers to comfortable indoor

conditions (temperature, humidity, airmovement)

Classes of Solar energy Utilization

Solar energy can be utilized in the following

ways:-Solar Architecture

Solar Thermal

Solar Electricity

* Off Grid

* Grid connected

Secondary Solar energy

* Wind power

* Geothermal heating

Solar Architecture

Solar Architecture refers to create buildingswith the perfect utilization of solar energy

Solar photovoltaics enable Architects tocreate buildings which produce their own Low

Carbon Energy ,whilst creating unique andvisually stunning designs

Plant Screens

Solar GrazingSolar Facades

*Solar Rain Screen Cladding

*Optimised Rain Screen Cladding


13/38

Solar Louvres

Shading is an important part of low energy building designthat minimises glare and over heating caused

by excessive solar gain. The use of louvres or brise

soleil to shade south facing facades is a proven means

of reducing solar gain, reducing

the need for artificial cooling.

Solar shading also reduces glare

for PC users and increase occupantcomfort whilst generating clean

renewable electricity.


14/38

Plant ScreensPhotovoltaics are an obvious choice as a protective

solution for plant equipment and roof mountedfacilities. Plant screens are naturally well positioned to

incorporate solar panels, receiving a

large amount of solar radiation

on at least two sides of the building.

Standard cassette solutions,

incorporating multiples of

solar panels, are easily

manoeuvred into position

and can be mounted on a

range of existing standard

framing systems.


15/38

Solar GrazingSolar Glazing is a unique combination of solar

photovoltaics and glass, where the PV cells arelaminated between two panes of specialised glazing.

The resulting glass laminate

serves the dual function

of creating energy and

shade at the same time.

Solar Glazing can be used

wherever conventional

glass would be specified

such as curtain walling,

atria, windows and shading

canopies, and can be

integrated into sealed glazing

systems or conventional bolted glass structures.


16/38

Solar FacadesRain Screen Cladding

Vertical Solar Facades directly replace conventional rainscreen claddingmaterials providing a smooth, flat facade surface for any building, with

a striking aesthetic.

This solution is best for buildings where the area available

for Solar Facade is limited

Optimised Rain Screen Cladding

Optimised Facades replace conventional rainscreen cladding with

rows of PV panels tilted towards the sun. This maximises the

amount of electricity generated, offering up to 30% more energy

from each square metre of PV panel.

It is best for buildings with large areas

available for Solar Facade installation


17/38

Types of Solar ModulesThere are many types of solar modules usingpresently in the world .

They are :-

*Single Crystalline Module,*Multi Crystalline Module ,and

*Amorphous Silicon

orThin Film Module.

Solar Rain Screen Cladding

CIS Solar Tower Manchester

In June 2005, the Co-operative Insurance Society (CIS) asked Solarcentury todevelop a solution for Creating a facade at their head quarters in Manchester

with PV panels. Arup then employed Solarcentury to act as PV consultantsand system integrators, providing specialised PV knowledge and design.

The project created the largest commercial solar facade in Europe, and is oneof the largest PV systems in the UK. It demonstrates how Solar Rain

Screen Cladding can be readily incorporated into building refurbishments toprovide an extremely cost effective alternative to conventional cladding

materials.

The CIS solar tower will generate enough electricity

to light 61 average three-bed houses every year.

Solar Plant Screen

Harris Academy , London

The Harris Academy in South Norwood was designed by John McAslan +Partners.

Architect Fanos

Solar cladding is the ideal solution for projects where space is limited.

Meanwhile the fitand forget nature of PV means it is a good renewable to choose for busyorganisations

where maintenance could be a costly issue.

The PV panels were simply mounted on the south-facing elevations of theplant enclosures

on the top of the schools five blocks, with further panels mounted on thefront of the

building as cladding.
