Where can you buy insurance for connecting to the power grid with a wind generator in Texas?


February 14th, 2009

A friend of mine would like to install a wind generator for electricity but the local power company won't let him connect to the power grid unless he can show that he has a million dollar insurance policy. He has called every insurance company he can think of and no one has this insurance policy that he can buy. The reason that he wants to connect directly to the power grid is that he does not want to have to use a battery bank but instead use the power grid to store electricity. Do you know where can get this kind of insurance policy in the state of Texas? Thanks.

Your friend isn't telling you the whole story. All you need to do is to call your local power company and tell them that you want a reverse meter so that they can measure the amount of energy you are feeding back into the power grid in order to assign you proper credit. There is specific wiring that you need to use that must be approved by your county. They require this specific wiring so that your system doesn't electrocute a lineman who is working on a line somewhere down from your solar power generator.

You don't go and buy a million dollar insurance policy either. You get an umbrella policy on your homeowner's insurance. An umbrella policy is property insurance that goes beyond what the homeowner's insurance covers. This is also sometimes called secondary insurance. You can google this to find a company that will sell this to you.

Just keep in mind that there are quality standards you need to follow if you connect to the power grid. You need a reverse power relay and an automatic transfer switch that will disconnect you from the power grid in case of a power outage. You also need to say "in phase" with the power grid. The manufacturer of the wind generator should tell you everything you need to know to do this.

How to build a wind generator for a sailboat?


November 21st, 2008

Does anyone know how to build a wind generator for a sailboat? I am looking for plans for a small 24" three blade wind generator ?

This manual is based on using a 260 VDC, 5 A continuous duty Treadmill Motor with a 6 inch threaded hub. These motors are available for under $50 from most motor surplus stores. We are getting about 7 amps in a 30 mph wind. In other words, it is a simple, cheap little machine to get you started.

"ASSEMBLY
1.Place the motor on top of the square tubing & bolt it in, using the two 5/16” x ¾” bolts.
2.Place the diode on the square tubing, about 2” behind the motor, & screw it into position using the self-tapping metal screw.
3.Connect the black wire coming out of the motor to the positive incoming terminal of the diode (Labeled AC on the positive side).
4.Connect the red wire coming out of the motor to the negative incoming terminal of the diode (Labeled AC on the negative side).
5.Center the tail over the square tubing, at the back end. Clamp your tail onto the side of the square tubing.
6.Using 2 self-tapping screws, screw the tail in place.
7.Place each blade on the hub so that all the holes line up. Using the ¼" bolts & washers, bolt the blades to the hub. For the inner three holes, use two washers per bolt, one on each side of the blade. For the outer three holes, just use one washer next to the head of the bolt. Tighten.
8.Hold the end of the shaft of the motor (which comes through the hub) firmly with pliers, & turn the hub counterclockwise until it tightens & stops.
9.Screw the nipple tightly into the floor flange using a pipe wrench.
10.Clamp the nipple in a vice so that the floor flange is facing up & level.
11.Place the square tubing (and everything that is on it) on top of the floor flange & move it so that it is perfectly balanced.
12.Through the holes of the floor flange, mark the square tubing at the point of balance.
13.Drill these two holes using a 5/32" drill bit. You will probably have to take off the hub & tail to do this).
14.Attach the square tubing to the floor flange with two sheet metal screws.
For a longer life span of your wind generator, you should paint the blades, motor sleeve, mount & tail."

What are the right batteries for a wind generator and where can i find them?


November 21st, 2008

I am looking into building my own wind generator but I don't know the right batteries I should use. Any help would be appreciated.

You are looking for what are called deep cycle batteries, not car batteries. The difference between deep cycle batteries and car batteries is that deep cycle batteries contain solid lead and can withstand losing almost all of their charge and then be re-charged over and over again much better than car batteries. Car batteries will explode or just stop working when you run them down and charge them again about 10 times. As you can image, with solar panels connected to a battery bank, you need batteries that can be drawn down and then re-charged again hundreds of times.
