A wind generator is a prudent option in today’s age when one is willing to cut down on the rising costs of electricity. A wind generator is also very environment friendly in that, it draws power from a renewable resource of energy. The wind generator has come to be associated with the concept of a green earth and energy conservation. There are wind generators that can be bought and installed at home. However, this is a pretty costly option and many, today, are building a wind generator at home. Building a wind generator is a tricky job, though not exactly impossible. All it takes is a little bit of knowledge about basic generator set ups and loyal following up of the generator building plan and guide. Once a wind generator is built for home, one can forget being bothered about the time duration for which the lights are on or the units of electricity being consumed. Once one has decided to build the generator, the next step is to get hands on a plan that suits all requirements. One important consideration that needs to be made in this regard is the budget one can allocate for building the wind generator. However, once the wind generator is made, the investment shall give warranted good returns.
One can make a wind generator with the aid of very common materials that need not necessarily burn a hole in the pocket. A wind generator taps wind energy and converts it into electrical energy. The basic requirement, for any model of a wind generator, is the blades which moves and in turn rotate the motor fitted inside the generator unit. The motor for the wind generator as well as the battery can be purchased from any electric parts store.
Factors to Decide Upon:
The first thing that needs to be decided before one starts work on building the wind generator is the location where it has to be placed. Ideally a generator fed by wind energy should not have any obstructions around. It must be placed at a height of about 25-30 feet from any obstructing object. From the area of the generator site, there needs to be no blocking object within a range of radius 350-400 feet. The nearest meteorological office can be consulted for a map of the general wind directions in the area. Observe the pattern of wind at various times of the day for a week to gauge its general trend.
Before starting on building the generator, select what kind of generator is best. They may be stationary or tilt up kinds of wind generators. The generator battery must be at least 48 volts. This capacity needs to be decided on the basis of electricity requirements. A rotor too needs to be fitted to the wind generator. On the basis of wind speed, power requirements and the size and capacity of the generators, choose a design for the rotor.
Tools and Materials Needed:
· PVC pipe
· Bracket for Pipe
· Two by Four piece of lumber
· Plastic sheet
· Block of lumber
Steps to Build the Generator:
Step 1: Wind Generator Blades
Take the PVC pipe. This can be purchased from a hardware shop. Decide the length as per the size of the wind generator being built. Pipes used in gutters are ideally suited to this purpose. The breadth of the pipe must be at least 20 percent of its length. On the basis of the wind generator size choose the wind blade length. Twenty inches is the standard size used for a homemade wind generator model.
Step 2: Attaching Directions
Take the pipe and cut it up into four pieces such that all these pieces are of the same length. Make a half cut diagonally and carve out triangular shapes from the pipe. These shall be the blades. Take a round metal piece that has a hole at the centre. At a hardware store you can purchase these hubs. The diameter of the hole must be such that it can fit up with the motor. Place the blades around the rim of the hub and make sure they are at equal gaps. Screw up the ends onto the hub rim. Now slot on the hub, with the blades, on the motor and ensure that the set up is snugly fitted. Now take the motor and place at the end of the two by four wooden piece of wood. Cover the motor with the plastic sheet so that it receives protection from moisture and rain. Cedar wood too can be cut into blades of the desired length instead of PVC pipes. The motor must be of 40 volts.
Step 3: Wiring
At the free end of this one yard piece of wood, place tough plastic which forms the tail of the set up. This is required for maneuvering of the movement of the wind generator blades. Using the drill, make a small hole at a place behind the motor of the generator. Fit the pipe bracket underneath and next, take a small piece of pipe and position it into the bracket. The wires attached to the motor needs to go through this freely moving pipe attached. The wires must be coated with water proof insulation and must be made to run in a way that they remain out of reach of any rodent or small animals.
Step 4: Securing the System
The large block of lumber shall act as the base of the home made wind generator. Place the base on the ground and secure it so that it remains in place firmly. Now take the wind generator set up built and attach it ion to the base. Fix it in a manner that it does not get off the position under any circumstance.
Step 5: Final Steps
Attach the wire ends to the battery terminals according to the diagram of the connection plan. Read the guidelines carefully and make sure the rubber gloves are worn while dealing with these components. The wind generator system is all ready for use. The next gust of wind shall initiate the generation of power.
Maintenance and Permission Tips:
Before building the home wind generator, one needs to obtain the required permissions and sanctions from the local utility centre of their state. A meter too needs to be connected and the net arrangement for the meter too needs to be obtained from the regulatory office. There are rules for net metering which vary from state to state. The home wind generators save up to a huge amount on electricity costs. According to the unit of the generator, the savings vary. The speed of the wind and related factors too affect the costs. The noise garneted out of the wind generator is not very high. Annual maintenance services can be booked with local generator contractors. Maintaining wind generators at regular intervals is needed to make them last long and function smoothly. Oil the blades and the motor from time to time. Check that all screws and bolts are in place. An annual check is good enough. A home wind generator can last at least 15 years with timely maintenance.
Remember that the home made wind generator is of eco friendly rating. The expense incurred is negligible. The hardware stores have ready stocks of motor and wires. These are the only equipment required. The other materials are all very light on the pocket. However, make sure that the quality of the materials being used is not very poor. The material should be sturdy and obtained from a reliable source. This shall affect the performance of the generator being made. Make an estimation of daily consumption of electricity at home. Choose the wind generator power unit accordingly.
