Solar Light Products: Use Solar Lights For a Brighter Future
http://bit.ly/Mt7V4D
We’ve all been advised to switch to energy efficient light bulbs. This makes good sense: they use less electricity and last longer than conventional incandescent bulbs. It’s an easy fix, too. We hear less about switching to solar power. Technology has made tremendous strides in bringing reliable and versatile solar lighting options to the market place. Even so, most of us think of big collection panels on rooftops, and we hear of the money you have to spend. These things have been true. To really harness the power of the sun for your electricity needs, large solar panels are the way to go. But, what if you are interested in solar power just for lighting? You’ll be pleased to find solar lighting is available on a scale that’s very easy to manage. With the average consumer in mind, many products can now become a part of your everyday life, as much as the traditional light bulb. You’re pleased with your energy efficient bulbs and wonder what would entice you to bring something new into your life. Well, there are four reasons why people switch to solar lights. The first reason is money. Once you’ve purchased your solar light, it costs no extra money to operate. The second reason ties into the first: Most solar lights use LEDs, a very bright type of bulb. These can last thousands of hours at zero cost! The third reason is knowing that in choosing from among the dozens of solar lighting products available, you are helping the world’s energy crisis as

Solar Chimney: Solar Chimneys
http://bit.ly/O6c0KT
by . SantiMB . A new solar energy technology solution has been put to the test, and has been given the go-ahead for production in Australia. This new solar power station is based on solar tower technology designed in Germany. An incredible thing about this new technology is the simplicity of its design, and its ingenious use of basic principles of physics to create energy. So what is this new solar energy plant? This new solar tower, also referred to as a “solar chimney,” uses solar power to turn wind turbines. Solar energy to turn wind turbines? How does this work? Well, the simplest way to describe it is to compare it to a huge greenhouse with a large chimney. As we all know, hot air rises. The greenhouse within the solar chimney system captures the heat of the sun. The heated air in the greenhouse is then allowed to escape through a huge chimney. Before the air escapes through the chimney, it is forced to pass through wind turbines, which are in turn used to generate electricity. You can see a diagram of it here. The beauty of this technology is that it uses centuries-old tried-and-true principles of updraft. Thi

How to connect or use Solar Power Panels?

by CoCreatr Question by Sol : How to connect or use Solar Power Panels? My family moved into a house that came with solar power panels but they are not connected and don’t really understand how to even begin. Best answer: Answer by wind m You need to know some electrical basics. You need to check if they are still working and determine the output voltage with the use of testers. They are just part of a system that includes other equipments as well like a controller, car batteries, inverters, diodes. Answer by Ed You will need help with this. Panels may or may not be 24 volt. If you can find a name tag, you can find out from the manufacturer’s web site. Some folks hook them all in parallel. Mine are in series, to create 480 volts. the reason for going to higher voltage is to reduce power loss in the wiring. Even then, I used a wire size larger than recommended. The frames want to be interconnected, and wired to ground. The live conductors connect through disconnect switches to an inverter. The inverter is sized to the output of the panels. Where the utility allows net metering, the inverters

Waterproof Solar Charger: Is There a Waterproof Solar Charger?
http://bit.ly/N5CHNj
Many people using solar chargers want to know if there is a waterproof solar charger available. Most of these people who like to use their solar chargers while at the beach are afraid that the water splashing around will ruin their chargers. Solar chargers are very durable and most can withstand the normal splashing that occurs at the beach. The sun power that is used to operate a solar charger is a great way for people at the beach to keep their electrical devices running. Because solar chargers are meant to be used outside, they are naturally waterproof. They are made to withstand rain and other natural weather that may occur around them. Weatherproof solar chargers are easy to find, the actual concern is more for the devices you are going to be charging with your solar energy charger. Most electrical devices that you will be charging with your charger are not weatherproof or waterproof at all. So even though your solar charger may be able to withstand a little water being splashed on it, that does not mean that your cell phone will be equally capable of operating in those watery conditions. It is extremely important to keep all your electrical devices out of any water. Most devices will be ruined with very little water coming into contact with them. For those people who like to use their solar chargers at the beach, this can present a huge dilemma. They want to use a solar charger while relaxing at the beach, but they do not want to risk ruining

Solar Thermal: Solar Thermal Vs Solar PV
http://bit.ly/MDG0xf
by ACEP UAF Introduction to Solar Thermal and Solar Photovoltaic Power Most people don’t even realize that there are two types of solar power. They just assume that solar thermal and solar photovoltaic are two names for the same type of energy. In a way, that’s true. Both types harness the energy of our sun, but are totally different. With thermal, sunlight is concentrated on a working fluid to produce heat to power a heat engine. That heat engine cranks a generator that produces electricity. There are numerous types of liquid and gas working fluids, such as water, air, oil, nitrogen, salts and helium. Additionally, the heat engine will most typically be a gas turbine, a steam engine or a Stirling engine. However, there are other kinds of heat engines that can be used. Heat engines have a high efficiency rating between 30 and 40 percent. They can produce up to hundreds of megawatts of power. Solar PV doesn’t involve a heat engine. Instead, it uses solar panels to directly convert sunlight into electricity. Solar PV only works when the sun is shining. It is ineffective at night or on cloudy days. Electricity is difficult to gather and save, which makes solar

Energy demand in megawatts?
http://bit.ly/LigtH2
by cheerfulmonk Question by Krys L : Energy demand in megawatts? Looking for some clarification on this: “[institution] has a current electrical energy demand of approx 15,400 MW-hrs. This energy demand equates to an annual output of a 13.7 MW solar array.” What exactly does it mean, “13.7 MW solar array”? Is that a solar array producing 13.7 MW per hour? Per day? What’s the 13.7 MW rating based on? Best answer: Answer by [deleted] If you had a 13.7MW bulb, it could power it. Answer by billrussell42 You are confused between energy and power. You are not alone. Energy is an amount, like the energy in a bag of coal. Units are in Joules or watt-hours (or kW-hours or MW-hours) Power is the rate of use or generation of energy, so it is in units of joules per second (watts) or in watt-hours per hour (also watts). So a 13.7 MW generator outputs 13.7 MJoules per second, or 13.7 MW-hours per hour. Annually, there are 8766 hours per year, so:
13.7 MW x 8766 hours / year = 120000 MW-hours. That does not equate to 15,400 MW-hrs so they must be accounting for the fact that the solar array is generating power for a lo
