OUTDOOR SOLAR LIGHTS

I have seen so many examples where the light is purely a very dim glow.
Are the LED versions any better than the ones seen on market stalls?

Solar Powered lights require enough light to charge the solar batteries. If the charging is impeded in any way, the light will be dim. I found that the LED lights take less engery to charge and stay on longer, even when we have had numerous cloudy days. Make sure you get a charging unit for the solar powered lights that can be mounted in direct sun. That means there will be a wire. Otherwise, if the solar panel is located on top of the light, you will need to be sure that the panel is exposed to light for a good portion of the day to get them charged properly.

Solar Energy Booming in China

Solar Energy Booming in China

The city of Beijing, China’s second-largest energy consumer, has announced plans to build a “solar street” where buildings, streetlights, and other features will run entirely on energy from the sun. A second pilot project in the city’s Xuanwu Park will introduce solar power for lighting, heating, and refrigeration. .

In a move to cut domestic reliance on coal and oil, the Chinese parliament passed a historic law in February pledging to use renewable energy resources for 10 percent of China’s energy consumption by 2020. The new law includes details on the purchase and use of solar photovoltaics (PV), solar water heating, and renewable energy fuels. In particular, the government will promote the use of solar PV in b

China will bury the earth in waste and its OK because its not the US

I was checking in internet about revenue business,I found the following information.

Silicon energy business

Silicon manufactures and distributes a large selection of residential solar panels, solar cells, lights, fountains, and hot water systems

founder in 2003

Revenue 2005: $1.1 million

Revenue 2008: $5.4million

employees: 35

growth: 390.2%

type:Energy

now is it possible to get those number in real life? with 35 employees got $5.4million? depend of the business but if everything track well is it possible? I found in inc 500 it;s supposed real business.what’s your opinion
ubicated in united states

In an IT biz, absolutely positively possible!

I want to know the total investment on Solar Energy PLant for my home. My requiement is, it should provide enough energy for Water heater, (4)Fan, (8)Tube Light, (1)Computer and (1)Television set.

What is required energy (in term of Watt) for above appliances?

I would suggest that you consider installing two different solar devises; one for heating and one for electricity. Water can be heated by collecting solar energy in a panel that allows sunlight to pass through a treated glass or plastic pane and shine on a black convoluted surface that avoids reflection. The heat produced can not escapes as easily as sunlight enters. This is the greenhouse effect that heats your car on a rather cool day. Inside the solar panel there are tubes or pipes that circulate cooling water to carry off the heat to an insulated storage tank. In cold regions the cooling water must contain antifreeze. The panel shoud be placed on a roof nearly perpendicular to a line from the sun at noon durning the cold season. In the upper USA that would be a southern exposure. The solar panel can be used to pre-heat water that is further heated by an electric or gas waterheater. The number of panels you will need will depend on the number of people using hot water and whether you use it as the sole source of warm water or as preheat. Expect panels to cost hundreds of dollars, depending on whether you install them yourself.

For electrical loads, you should consider installing photovoltaic solar panels which produce direct current (DC). This can be used for heating water or running electrical equipment and lights but heating may use up the entire capacity of the panel(s). You may need a battery to store energy and a converter to provide the correct voltage (and AC?) as desired. Expect voltaic solar panels to cost less as new technologies come to market. DayStar is building a factory now to produce cheaper continuous film cells (that could cover a roof?).

The wattage for various items you wish to power is usually included on the manufacturer’s identification plate and depends on the size and model you have or wish to buy. Good luck.

….. Please help me to find a very good site which provides me with solar power lighting and water management systems , we can get ground water by digging a pit but I need the water pump and storage tank.. some information on this please.

Let me start off by saying we (my family and I) live completely, 100% “off of the grid and are completely self sufficient”
The house is built utilizing natures natural elements, in the shape of an octagon with 8ft wide arch doors on every wall to catch every angle of wind (typical 4 sided homes have half the chance as one with 8 sides. A circle being the most efficient design). Woodburning stoves, solar chimney, solar AC, solar heating, solar water heating (pool and home), solar stove, solar power, wind power, hydrogen powered back up generator, hydrogen back up water heater, hydrogen stove, 2 hydrogen powered trucks, 1 EV (electric vehicle) and satellite internet.

We also built many green small cabins on the ranch that we offer to family, friends and our on-site off-grid workshop guests, including one straw bale, one papercrete, earth bag and adobe, one cob and cordwood, one underground and rammed earth, one log and post and beam and one rock. Each one actually started as a test for what the main house would be and were later finished and turned into guest cabins. I later wrote a guide on how to build with alternative materials using alternative methods for next to nothing.

U-SEE (Unlimited Savings of Electrical Energy), a World Bank honored innovative idea for reducing misuse of electricity units is explained. It does not involve technology nor requires billions. U know solar light is infinite. Many of us burn bulbs during day time for lighting purpose.Sun is shining just outside our window. Let us bring home the sunshine. Switch off all bulbs and do the following.

U need simple house hold mirror, small pillow. Place the pillow on the ground or a chair outside the window and place the mirror on it in an angular position so that sun’s rays falling on the mirror is deflected through the window and on to the white ceiling and watch natural light spread inside your room.Use a bigger mirror and u can vary the lux and lumins of light. The light u get is free, reduces bulb burning/global warming, preserves natural resources. We can save 7,00,000 units per month if 1,00,000 people can stop using one bulb during day time. Let’s do it
mail: vkumar_m@yahoo.com
Browse World Bank website 4 U-SEE: http://dmblog.worldbank.org/mirrors-can-bring-light-rural-homes

This U-SEE idea is so simple and to make it work all of us can become innovators depending upon the place where the sunlight falls in and around your house. If u r innovative, u can even take the sunshine into other rooms by placing another mirror to take a part of the sunlight deflected by just altering the angle of the 2nd mirror. Anywhere in the world, we can safely assume that sun’s rays will be available between 150 to 200 days in a year. Imagine, if half the world’s population adopts U-SEE and switch off two or more bulbs and get free light from U-SEE what would be savings accruing to our future generation!? Save the world please.
One of the answerers is trying to correct English language used in the question. My request to him is, please take the crux of the matter in a holistic manner or else learn SMS and MMS language used by the present day generation. I am trying to create awareness on misuse of electricity and not usage of language. Have a look at the language used in other answers on varied subjects and then come back, if u must.

Buying my first home. Would like to save on bills by utilizing wind energy/solar power, waste oil heaters, insulate home good, and switching lights to florescence/leds.

Any other ideas people got out there?

You can get a federal tax credit for up to $1,500 for making "green" improvements to the home. There are details of it here http://www.energystar.gov/index.cfm?c=tax_credits.tx_index and it also lists different improvements, which may give you some ideas of what to do as well.

Some of the things I didn’t see you mention were geothermal heat pumps and thermopanel windows.

- Which green products do you believe have the greatest impact for the for personal use?

- Which ones do you like the best?

- Which ones are a waste of time?

- Do you go out of your way to buy earth friendly products if it is a comparable price and quality?

- Would you be willing to pay a little extra to buy more earth friendly products?

- Do you even take it into consideration if it is earth friendly or not when making your purchase decision?

- Do you think that people overstate their "greenness" to be trendy?

- Are you considering buying green Christmas/ Birthday Presents?

- Which of these do you consider earth friendly:

Solar products
recycled products fair trade
wind energy Products
organic products
bamboo products
efficient lighting
recycling assistants (bins, can crushers, sorters, water purifiers, water bottles, etc)
Earth Friendly cleaning supplies, cosmetics, body care products, etc.

I would greatly appreciate people providing feedback on this topic.

Basicallly I am starting a green goods store because I try to buy everything I can that is eco friendly, and I have found that a majority of it is crap that Ii end up having to pitch anyway, and almost all of it is overpricced for what you get bbecause it has the "green" label on it. Obviously I am in it to make some money, but I am primarily in it to help others to be more environmentallly friendly, be confident in the quality they will recieve, and know that each product was researched for the validity of their "green claims".

What do you all think?

I believe that products that create the biggest impacts will be products you use frequently.
Some examples would be:
Eco-Friendly Household Cleaners
Reusable Bags
Efficient Lighting
Recycling Products

Items like solar phone chargers and wind energy radios for the most part seem to just cash in on the "green" label and either don’t function correctly, are too costly, or just useless.

I am willing to pay more for an eco-friendly product if it is well made and if I’m sure that it really is a greener alternative.
