A Simple Homemade Solar Power Generator – Build Cheap DIY Solar Powered Generators Plan

Use of renewable energy is now being harnessed by many people as calls for environmental protection and natural resources conservation are being the talk of the town. Consumers also are now finding ways and means not only to help mother nature but also save and spare money from the cost of daily living which is now becoming higher and higher. It is good to know on how to build cheap diy homemade solar powered generator.

Solar energy generator are basically like batteries which stores energy from the sun and keeps this power stocked up until usage for such is needed to run appliances or electrically run apparatuses.

Building a solar energy generator is initially costly and spending out a reasonable amount of cash is the only way to go. However return on investment is very good and feasible since the large initial amount is sheled out only once (during installation except of course for probably maintenance and repair), however use of such is electricity and power is on the daily basis. Savings must be huge as the increasing price of electricity is cut into half or much better zero as dependence on using the solar energy generator becomes a hundred percent. Return of investment may be attained in a couple of years or much shorter should price of electricity continue to soar.

To start making a solar energy generator purchase of solar panels is needed or building one's own can also be accomplished (choosing which option one must take will depend on the financial situation and the capacity of the person to make such from ordinary items). If buying of a solar panel is the chosen selection by the user it is suggested to buy a solar panel whose rating is 12 volts. Buy or acquire also a dc meter, an inverter (to convert dc to ac which is needed by some electronic devices) and deep cycle batteries (choose batteries which are dependable and are capable to handle long and continuous usage). Building a suitable battery box may also be required to keep the equipment from being destroyed and for curious people from getting hurt. Insulation is also proposed for purposes of safety, efficiency and quality output of the generated electricity.

To start off making a solar energy generator the meter as well as the input device is attached to the battery box and after this all these items are now part of the box, together with the DC meter and the inverter each are connected to the solar panel .

This type of solar generator is able to run small household appliances such as electrical fan, personal computer, radio and television however this is dependent on the quality of charge it receives from the sun's rays. The capacity of the solar energy generation is dependent on how much it was able to get and receive from the sun. Know you have a better idea on building a cheap diy homemade solar powered generator.

No Generator Output? Flashing The Field To Fix Or Troubleshoot

As a former employee and current owner of an industrial generator rental company and electrician with 15 years of generator troubleshooting experience, I’ve had many situations where the engine powering the genset is running great, but the generator isn’t producing any electricity. There are plenty of articles on the internet explaining how to flash the field in order to re-magnetize the generator, but this one will go a step further and also explain how artificially exciting a generator can aid in narrowing down the cause of the failure.

A WORD OF CAUTION…

Just because you don’t see any volts on your panel meter doesn’t mean that you won’t be electrocuted. Remember, the panel meter can be flawed, check it with a hand held multimeter. Secondly, flashing a field results in a build up of magnetism within the generator. Over time of inactivity, the magnetism may dissipate entirely and flashing the field “refills” the missing magnetism. It is, however, entirely possible that the reason for the generator losing output isn’t related to a lack of residual magnetism in the generator. If this is the case, then there will be a voltage present that is lower than the rated output voltage, but definitely enough to cause a painful electrocution.

CHECK THIS BEFORE YOU FLASH THE FIELD…

Use a multimeter to check if there is any voltage present at all. If there is, then it’s a good indication that the problem is not within the generator.

Shut the machine off and locate the voltage regulator. You’ll find 2 wires marked F+ and F-. Pay close attention to where each is and remove them. Put your multimeter on “Ohms” and measure the resistance across them and write down the result. Unfortunately each manufacturer has different values as normal, but 0 and infinite ohms are two bad news signs that you’ll require the services of a generator rewind shop. If you have ohms, leave the wires off and keep reading.

HOW TO FLASH THE FIELD…

Ideally you’ll have a variable DC supply available. If not, use a 9V battery, or even a car battery and carefully hook up the [+ to F+] and the [- to F-].

Start the engine, and keep it at low idle if possible. You should instantly notice a voltage is present. As you increase engine RPM, you’ll notice the voltage will increase. Do not go beyond rated voltage. Keep the machine running for 30 seconds and shut off the engine.

Re-connect the F+ and F- to their original location. Now start the engine and see if you have volts.

I STILL DON’T HAVE ANY VOLTS…

By flashing the field and bringing the machine up to proper voltage, you’ve effectively ruled out any problems within the generator’s main windings (the most expensive repair).

You should now focus on the AVR (automatic voltage regulator), a fuse in line with the AVR, or a wire or switch that supplies the AVR. Do “tug testing” of wires, visually inspect everything that you can. If nothing wrong is found, contact the manufacturer of the generator and find out what the ohms of the field should be and compare it to what you found earlier.

How to Make a Wind Generator to Power Your Household Appliances

Because of the uncontrollable price hikes of conventional energy sources such as fossil fuels, green and renewable energy has become one of the most common subjects in every conversation. People are now focusing on how to make a wind generator that is efficient enough to power off grid homes. The exhilarating technologies that offer a clean and sustainable energy source that is free and off the grid has captured the interest of a lot of individuals. Places or locations that have a stable and high amount of wind are prime spots to build a wind powered generator that will help to supply your household's electrical requirements. Although making a wind generator yourself can be quite a challenge, it is entirely possible.

In making your own home wind generator, you should first measure the wind around your property and in the general area using an anemometer. Look for an anemometer that you can easily set up and return by the end of the day. Check the results of your survey by looking at the stats such as the highest wind speed recorded as well as the average wind speed. Make sure to measure the wind speed in various locations several times to establish the best spot to construct your wind generator. Generally, a ten mile hour wind speed will produce around a hundred watts of electricity for a wind generator system with a four meter blade diameter.

If you carefully observes some of the how to make a wind generator guides, you will learn that you can convert the powered treadmill motor into a stable magnet alternator. Try to break open the housing of the treadmill to access the generator. It should read "permanent magnet motor". Carefully attach the base of the blades from the turbine casing to the flywheel that is securely fastened to the end of the treadmill motor. Put in the blocking diode that will be positioned between the motor and the deep cycle batteries to make sure that it will not drain the batteries.

You can now get a set design so you can start carving your blades. The most critical features on your propellers are the number of blades you will use as well as the length or diameter. Bear in mind that the larger the blades are, the more wind will be captured by the system, which can generate a greater amount of electricity. However, the larger the blades, the slower they will spin. In other words, large blades are only suited for areas with strong wind speeds.

When assembling your hub, make sure that it is big enough to house the treadmill's power generator, which will be converted into a permanent magnet alternator. Surely fasten the turbine blades onto the front of the housing and the tail in the back. Carefully weld the permanent magnet motor to the casing for the wind generator hub. If it is possible to attach them without welding, sometimes by using zip ties or other types of connecting materials like a strong adhesive or bolts and screws, then that would be better.

Hook up the appropriate wiring from the generator to the deep cycle batteries. Make sure that when you put the electricity regulator in the circuit, it is between the batteries and the generator. This way, your system can block any excess electricity from going to the batteries and shortening their life span. Now you have done the impossible and learned how to make a wind generator on your own.
