Solar Garden Lighting

If you want to know about the technicalities of solar lighting... and what it is composed of... then please refer back to our post of March 28th, 2007 in the Archives, where solar lighting is discussed in detail, together with links to helpful online sources of information and supplies.

This post is just a reminder to all those in the Northern Hemisphere that we are coming out of winter! It's time to go to the garden centre, DIY store, ironmongers... or wherever you can choose your new garden lighting and buy some of the gorgeous new generation of solar powered garden lights.

Have you ever visited... http://www.thehungersite.com http://www.theanimalrescuesite.com http://www.therainforestsite.com or any of their sister websites? You will find lots of beautiful solar lighting ideas there, together with many other gift ideas... and they are all sold in aid of the particular good cause you prefer to support.

Solar power... all the facts you want to know

First let's consider solar lighting for our gardens...

Solar lighting is created by turning sunlight into energy. Energy is created as sunlight strikes a solar collector, and then it turns energy into an electrical current. This electrical current then sends this energy to a power supply, i.e. rechargeable batteries, which in turn energizes a lamp source [LED - type of tiny light bulb].

Some calculators have solar cells and never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever.

The idea that one day we will all use free electricity from the sun is an extremely seductive promise. One day, when technology allows, we could collect solar energy so that we could easily power our homes and offices for free [always assuming the corporate energy suppliers allow it]. But, to start with, solar lighting for your garden makes great sense as it is easy to install, has no wiring to install... and no electricity costs.

Solar lights are composed of:-
A plastic case
A solar cell on top
A single AA Nicad battery
A small controller board
An LED light source [a type of tiny light bulb]
And a photoresistor to detect darkness

Electricity for your home... from solar power...

Solar panels turn sunlight into electricity. The battery charge regulator controls the flow of electricity into and out of the battery bank. The energy flows into the batteries, and then to the inverter. As detailed in a previous post... "Inverters take DC power [battery or solar, for example] and convert it into AC "household" power for running electronic equipment and appliances."

The power conditioner [inverter] turns that electricity into a safe, ready-to-use form that flows through your home's electrical outlets. Excess energy is stored in the battery bank for later use.
