The Sun

The sun emits Lightalmost all of its energy in a range of

wavelengths from about 2x10 -7 to 4x10 -6 meters

Most in visible range

Solar cells respond differently to the different wavelengths,or colors, of light.

Solar Panels

Solar energy panels arephotovoltaic (PV) devicesto produce electricity fromsunlight. They are made ofsemiconductors, mostcommonly thesemiconductor silicon.Solar Panels come inmany sizes, colors,performancecharacteristics and brands.Certification and long time

manufacturer warranty atwholesale prices.

Generally available Panelsfrom 10 watts to 225 wattsof world's leading brands.

Balance of System Components

Solar Batteries In order to provide uninterrupted powerduring power outages a battery back-upsystem is required in Solar Energy Systems.Battery back-up systems use deep cyclebatteries that need very little or nomaintenance. A controller is used to preventthe batteries from being overcharged oroverly discharged.

Solar Charge Controllers

A Solar Charge Controller is a devicethat regulates the amount of currentPV modules feed into a battery bank.Their main function is to prevent over- Charging of the batteries, but chargecontrollers also block the reverse

current from a battery bank fromleaking backwards into thephotovoltaic array.

Solar Inverters

An inverter takes current frombatteries (DC) and turns it toalternating current (AC) to run anycommon loads. To determine themaximum power you require, and thesize inverter you need, make a list of

all the equipment you will run, and theamount of time it will be in use.

Advantages of solar power

You are able to produce solar power for your home throughincreasingly easier and cheaper methods related to thisnatural energy source.One of the main advantages of a solar power system foryour home is the lack of pollution given off by solar panelswhen generating electricity.Another advantage of solar energy is that the energy source(the sun) is completely renewable unlike the source which isprobably generating your current power supply .The initial investment of solar panels is quickly seen as asmall price to pay when you realize the savings you couldmake over the coming months and years on your electricitybill.Solar energy not required any type of fuel un like (gas oil andcoal).The saving are immediate and for many years to come.

Disadvantages of solar power

Solar power would only be viable with currenttechnology as long as the sun's photon atoms canstrike a solar panel directly. If there is no sun,there is simply no power.

Some disadvantages of solar power are economicin nature.Solar panel require quite a large area for

installation to achieve a good level of efficiency.The production of solar energy is influenced by thepresence of clouds or pollution in the air.Similarly on night time no energy will be producedwhile you use battery as a backup.

Environmentally friendly

Solar energy is clean , renewable unlike gas, oil and coal.

It does not pollute any type of gas like CO2, NO 2 SO 2 or HgInto the atmosphere.

Solar energy does not contribute any type of global warming acid

rain and smog.

It actively contributes to the decreases of the harmful green housegas emissions.

It's generated where it is needed.

By not using any fuel therefore, the cost and problem of the recovery and transportation or the storage of radioactive waste.

Low/ no maintanance

Solar energy system are virtually maintenance free and willlast for decades.

Once installed there are no recurring costs

They operate silently, the have no moving parts, do notrelease offensive smells and do not require you to add any fuel.

More solar panel can easily be added in the future when yourfamily needed grow.
