Anyone know where I could access solar panel and wind generator for small home from reliable supplier? Thanks?
Try to help small village home with their drought, electricity, farming, small industry, pump and water problems. They got plenty of wind and sunshine but rather dispense with fuel operational cost. Perhaps wind generator and solar panel generator could be the solutions. Besides being a good standby reliable no cost operation it also help prevent greehouse emission. Looking for a reliable products and supplier both for sosial and commercial purpose. Appreciate any website you could introduce me to. Thank you.
i know that tractor supply company carries solar panels but they are not high producing. Each set cost around 300 bucks not including the batteries. I’m going to use complete solar energy for my house. I figured that it would take 3 sets of solar panels from tsc. Each set using 4 marine batteries would cost 2500 to 3000 bucks and it would produce enough power run my most basic energy needs. As far as wind mills i haven’t checked that idea out yet but i will soon enough. I hope that you find what you need. Good luck.
easiest way to quiet down a portable generator?
I am looking to run a generator to power my mobile home when my solar and wind generators aren’t making enough power. I usually park in semi suburban areas and the last time I ran my generator for a prolonged period I got a noise complaint and had to move at 3am [not so fun] what are some ways to quiet down the generator while its running?
I had the same issue with an air compressor. I built a wooden enclosure with a small fan to bring cool air into the box. It has worked fine for over twenty years! But for your problem:
Find a cardboard box that will fit comfortably, upside down, over the generator. If that is not enough, glue some fiberglass insulation inside the cardboard box. That will decrease the decibels sufficiently. Otherwise, you will need to build a wooden enclosure with fiberglass insulation inside.

What is the difference between these wind turbines?
the types of wind turbines i found was
industrial, agricultural, commercial, municipal, and residential
what is the difference between these?!
which wind turbine is used where.
I only know residential is for homes & its the smallest of all the wind turbines
but what about the others?
also compare their sizes please
I do not think there is that many types of wind turbines because wind turbine’s solo purpose is to make eletricity and they don not really bulid them in the suburbs because it may be noise and it take a lot of space and also ot needs a lot of wind so only a limited area will be able to set up wind turbines.
Questions on windmills (wind turbines) for my home?
Hi, i am interested in getting a wind turbine for my home. I don’t think i can afford one to power the whole house, but want one to help with electric costs best i can. When looking them up, there are a bunch of websites and information that i am a bit confused as to what i should get. Is there someone on yahoo answers that has put one of these up or who knows about them and could maybe give me some advice? Thanks, i appreciate it
The turbine has to be 30 feet above surrounding buildings and trees. It has to be two tower heights away from any building. If it falls in any direction, it must not cross a property line. You pretty much need to have an acreage to have a wind turbine.

Earth4Energy questions, how long and how cheap?
I might be looking into buying that kit, and im wondering like what is the cheapest easiest first porject it shows you how to do, and for how much?
and how long does that first project take?
and how long do the other project approximately take and for how much $?
thank you very much
Eath4Energy is a scam. Please see my review at http://www.nlcpr.com/Deceptions6.php
If your motivation is to reduce your energy bills, then you should first look at conservation projects. These are things like using low flow shower heads, replacing old appliances and adding more insulation.
If your motivation is to generate some energy for learning purposes or as a matter of principle, then consider the following:
Building a wind generator yourself is not a simple project. If you can build an utility trailer for your truck (welding, metal fabrication) then you could certainly tackle the job. There is a great book available from www.otherpower.com called Homebrew Wind Power plus you can order any parts and assemblies that are beyond your abilities to fabricate. Cost of turbine is about $2000 and you need a tower as well. There are cheap units at some hardware stores but they are garbage compared to to the unit designed by www.otherpower.com
A more realistic project would be to get a commercial solar panel (making your own from broken cells on eBay is not worth it), inverter, charge controller and battery and using it to power some things in your house. For about $1000 you could have something to power a small computer. A complete system to power your home is more in the $30,000 range.
There are, unfortunately, no cheap ways to make your own power as Earth4Energy is promoting other than perhaps getting lucky in an eBay auction or purchasing a solar system from a bankruptcy sale.
Do your conservation measures first. Then read Homebrew Wind Power, read the solar links at http://www.nlcpr.com/Links1.php and then decide what type of project you are up for. By then, you will know exactly what you want to do.
Grid connect Controller for wind turbine driven induction generator (async motor)?
Thanks to your many very helpful answers to my previous questions I was able to find a company that sells such a device. As you may recall, I was intrigued by this device: http://www.clariantechnologies.com/main/page_home.html. It is a vertical axis wind turbine driven async motor that acts as an induction generator that plugs directly into an existing outlet in your home. No inverters, no batteries. Sales price around $500. With an electric meter (a freebie from our power company) than can run backwards, this would allow me to greatly reduce my energy bill all at a very low cost. To make the cost even cheaper, and to increase the power output, I want to make my own wind turbines, and use my own async motors. So all I need is the controller.
I have found a company that sells such a device: http://www.prairieturbines.com for $830. It connects a 5500 watt wind turbine driven async motor directly to the grid. No inverter, no batteries. It uses a “hall-device” to measure the RPM, it provides about 1 AMP to the motor to energize its coils, 50amp solid state “zero-cross relays”, capacitors, 30amp breaker/enclosure, an exterior mounted disconnect, and an interior-mounted fused-control voltage switch. This is it!!!
So my question is, does anyone know how to build this controller. This company doesn’t sell the plans to this, and $830 is too high for me. I am sure I could build this with components for less that $400. If there is any electrical engineering person out there that can help, this will be a challenge, but it is great knowing that someone already has figured this out and is selling it.
Look at the Prairie Turbines site again. The price of the micro-controller including the hall device is $255. The $45 book provides a complete list of material and instructions to build everything else.
The micro-controller monitors the speed sensor and provides control signals to two solid-state relays. One relay connects the motor to the grid when the speed reaches the motor’s 1800 RPM synchronous speed and disconnects the motor if the speed drops below 1800 RPM. The other relay is energized to release the brake when the controller is energized and de-energized by the controller when the motor speed exceeds the maximum safe operating speed. If this occurs, the controller apparently must be manually reset.
I did not find the maximum safe operating speed stated on the web site. If the full load speed of the motor is 1750 RPM, the full load slip is 1800 minus 1750 or 50 RPM. The speed at which the motor would generate full load current and present full load torque to the turbine is 1800 RPM plus the full load slip or 1850 RPM. With the design described, a three-phase motor is connected to a single phase source with capacitors connected between the source and the third motor phase. That is likely to increase the motor slip somewhat.
I am not sure what happens if the motor is driven above the speed at which it generates full load current. A three-phase motor operating as an induction generator connected to a three-phase supply has a torque vs. Speed curve that is something like the mirror image of the motoring torque vs. Speed curve. The curve is likely different with the single-phase connection used in this case. I don’t know what the speed vs. Current curve looks like in either case, but I will see if I can find it. I am also curious to know if the Alan Plunkett listed on the web site as an author is the Alan Plunkett that is well known author of technical papers on inverter and variable frequency drive subjects.
I found information indicating that, for a 3-phase motor connected to a 3-phase supply, the speed vs. Current curve for induction generator operation is like a mirror image of the speed vs. Current curve for motor operation. That would mean that the maximum speed would need to be limited to the synchronous speed plus the full-load slip. The web site indicates that the full-load speed for the motor that they used is 1725 RPM for 3-phase operation. That would make the maximum speed 1875 RPM plus the additional slip due to the single phase with capacitor arrangement.
