SELCO India, Affordable solar home systems – Ashden Award winner

This video can be downloaded here: www.ashdenawards.org SELCO won an Ashden Award for Sustainable Energy in 2005. To find out more visit the link above and check out the Ashden Awards Blog ashdenawards.blogspot.com SELCO-India is a private business which has designed and sold over 48000 solar home systems, powering electric lighting and small appliances for 220000 people in Karnataka and other states in South India. Around 46% of households in India do not have mains electricity, and for many others the supply is unreliable. The use of photovoltaic (PV) solar-home-systems (SHS) can provide reliable power for lighting and low-power appliances, which brings great practical benefits. Smoky, dangerous kerosene light is avoided, people have extended hours for work and study, and more opportunities for leisure and entertainment. Many programmes throughout the world have attempted to improve quality of life using SHS, but often they have not led to long term use and continuing markets. SELCO-India believes that the use of SHS will become widespread only if the system and after-sales service are of high quality, and if people want an SHS enough to pay for it. What they provide is properly designed and installed systems, excellent on-the-spot service and links to organisations which offer appropriate and affordable finance. The Ashden judges were highly impressed with the philosophy and excellent management within SELCO-India they have built a thriving business by providing poor

Some great benefits of photovoltaic lights

There are several benefits offered by photovoltaic lights, and in case you are not already aware about them then you will be, because you could be benefiting from all these positive aspects yourself.

Photovoltaic lights are usually exactly what their name indicates – lights that happen to be powered by the sun. They power up when the sun is out on them throughout the day, after which they can produce light in the entire night time the same as any light.

Benefits of photovoltaic lights

They are excellent for applications wherever a normal electric power resource is inaccessible and where accent lights are essential.

It is important to realize that although there are lots of rewards offered by these photovoltaic lights, they may not be perfect for all circumstances. They produce an intensive glow and give off beautiful shadowing around the surrounding areas, and so they are ideal for outside the house a home or lining a walkway.

Drawbacks of photovoltaic lights

For places that reguire a lot of lighting photovoltaic lights are usually often not the best alternative. And although it does not need to be sunny for the photovoltaic lights to work, you do require sufficient light to work.

Of course you’ll have to put money up initially in order to pay for the specific lamps, but they will more than pay themselves off within the first 12 months.

Save money with photovoltaic lights

It is obvious that the advantages are generally bigger then the drawbacks. Around the house in yards, gardens and  places where there is no regular power source photovoltaic led lights are the best choice. You will save money simply because you do not use normal electrical power plus they are no more expensive then typical yard lights.

You will notice the advantages offered by these low voltage garden lights immediately, and more than anything you will notice how much money you are saving by not having to use and pay for energy for your lights. Especially in your backyard and areas across the house where you don’t require a great deal of lighting, these lighting is best simply because they emit just the right amount of light and because they don’t cost you a penny.

A Solar Cell 1000 Times More Powerful

www.homemadepowerplant.com The achievement is that we separate out the collection function of a photovoltaic cell to the light conversion to electricity function. When we collect the light, instead of using a huge area of solar cells, we use an equal area of cheap glass mirrors and they are curved in such a way as to concentrate the light onto a very small solar cell, the size of just one cell, and in this way you concentrate the light a thousand times and you can get a thousand times more power out of a small cell. -Professor David Faiman of Israel

Passive Solar Panel Tracking

This is a video of the panels I will be using at the UF biodiesel plant. The solar panel arrays in the Solar Energy Park use a passive tracking system which allows for the panels to increase efficiency about 20%.
