Re the link, 45 watts is not much. It will power 1 or 2 CFL lamps, that's all, and that is when the sun is shining. and exactly at right angles to the array. Typical output is probably half that. You will need a charge controller, and one or more large sealed marine lead acid batteries, as well as an inverter. A good charge controller is essential, as the voltage and current output of a panel varies a lot. A good charge controller has a DC-DC converter that presents the optimal load to the panel to get the maximum power from it, and converts that to the right DC voltage to charge the batteries. .<br><b>References : </b><br> solar arrays are quite expensive and the payoff period is measured in decades.

With the same setup I measure a 2.7V output. But then if I place a flahlight bulb (3V) on the end I get nothing... no light. Will it work if I use a LED ? is there anything in the video that makes it work that we don't see ? thanks for your answer. Hi, for a school …

You can't transmit AC power through optical fibres, they don't conduct electricity. Large installations, built and operated by the utility companies themselves, are connected up in the same way as any other power station. Small installations, eg., renewables at home, require a legal framework called a feed-in tariff. You are provided with a metering set that measures how much electricity you have exported to the grid. The power gets to the grid through your regular supply lines. This is in place in Germany and will probably come to the UK in a couple of years time. How long the US will take to catch up is probably a matter for Obama to decide in 2009!<br><b>References : </b><br> Electricity from renewable sources gets onto the grid through metal wires.

]]> Comment on Using solar and wind to produce power from steam as needed? by GABY http://www.windsolarpowerhome.com/wind-solar-power-home/using-solar-and-wind-to-produce-power-from-steam-as-needed-2/comment-page-1#comment-1779 GABY Sat, 03 Jul 2010 13:51:59 +0000 #comment-1779 Collecting solar energy and producing steam to drive turbine generators is a good idea. There have been many experimental plants doing this over the years. There have also been many experiments done on the best medium to use for storing the heat during the night. My understanding is that the most favorable system at this point in time is using a large array of parabolic mirrors focused on a collector which has a salt slurry or other solution which circulates to a boiler to produce the steam. I followed one test plant in the 70's, and it worked, but finding a good heat absorbing medium that would not corrode the pipes and boiler was the biggest problem. Maybe they have resolved that now. I also understand there are some large scale plants now in service and more planned. Wind turbines are another matter. They are passive in that they (the wind generator) just turns when the wind blows over about 8MPH and produce electricity directly. Both are great sources of power, but also both depend on nature and weather cycles. Sometimes the wind doesn't blow and the sun doesn't shine. Many areas of the world are not well suited for these forms of power, and there is a limit to how far you can transport power over wires, so other more reliable sources will also be required for the 24/7 reliability we require.<br><b>References : </b><br> Collecting solar energy and producing steam to drive turbine generators is a good idea.
