How To Generate Electricity From Solar Power By Using Earth4Energy
Author: Steve Callen
Earth4Energy has successfully propagated the use of solar energy as a viable, environmentally friendly, and cost effective way of electricity generation and usage.
It reveals ways of transforming energy provided by the sun through its rays into electricity that can power homes.
Solar energy is produced by first collecting energy from its source, the sun, through collectors placed on rooftops of homes and buildings. Earth4energy explains how to set up solar panels, made from semi-conductor materials, to work as collectors. The panels need to collect solar power for at least 6-7 hours before a sufficient amount can be generated to power all the electrical equipment in a home. Direct sunlight eases collection and storage of solar power.
Benefits of Solar Energy
EARTH4ENERGY explains the benefits reaped by solar power. Firstly, the energy thus generated is a lot cleaner due to lack of gas emissions, as is the case if oil, coal and other sources are used. Secondly, solar energy is becoming a cheaper option as costs of installing the system are falling with continuous technological advances. Moreover, once the systems are installed and more energy can be produced than is necessary for the household, the surplus amount can actually be sold back to the power companies in the area at a profit.
Solar Energy as a Cost Saver
Using earth4energy’s guidelines to generate solar energy can be a big money saver for a salaried household. The contrast will be evident when the old electricity bills are compared to the relatively cheap solar energy generated. The underlying reason for this is that sunlight is available free of charge to everyone who wishes to use it. Earth4Energy also suggests setting up such a foolproof system that maintenance expenses are minimal.
Leading By Example
Solar energy systems installed by a person in vicinity is likely to evoke interest in the entire neighborhood, and hearing about the cost savings, many are likely to follow suit and use earth4Energy to set up similar systems in their homes. Leading by example in this manner can save our environment and also our planet.

how to generate electricity from a small motor that is used in toy cars?
I want to build a small dam for a science fair but I am not getting the turbine for generating electricity. But I am having a small motor that is used in electric toy cars. Just tell me how to generate electricity from it by connecting it to a home-made turbine?
What are good materials to generate electricity from?
I’m thinking of generating electricity from various objects and comparing the results as a science project. However, I need examples of things to test and compare. For example, food (we have potatoes and lemons already), solutions, and other materials that would normally generate electricity. The person who answers best within the first 2 hours of my posting will get Best Answer. Thanks!!
By the way, Im sorry I did not specify. However I need to basically know what materials to use to power a lightbulb for example. I need more than food products to do this experiment but I’m not sure what else to use.
How can we generate electricity from running wheel?
Do you know how to generate a electricity from the wheel of running vehicle ?
How to generate electricity for home from water?
Is it possible to generate electricity from water flow from an overhead tank placed in height. If yes what will be the limits (maximum watts) of such power generated? Can a water pump also work using the same power to re-fill the water tank, recycling the same water?
how much rpm is needed to generate electricity from 1 kva generator?
I want to know that how many rpm is needed to generate from 1 kva generator.
The amount of energy in the water can be calculated from
Power = Head x Flow x Gravity
The link below has an online calculator…
With 6 meters (a length of pipe) and 17 liters per second the power is 1000W. The losses in the pipes, turbine and generator could amount to 40% so there would be 600W available.
The reverse process of motor and pump and pipe losses would lose another 40%, so you could get only 360W equivalent of water back in the tank if you were just doing it as an exercise. As you can see it is a losing game. Perhaps these efficiencies can be improved, but perpetual motion machines are not considered possible, as there are always losses that cannot be overcome, due to the nature of the universe.
How exactly are you generating electricity?
If you are making a battery by putting two metal probes into a piece of fruit or solution, then you are really generating electricity from the metal. The fruit or solution you are talking about is just supplying the electrolyte and acid to break down the metals and transfer the ions. The actual energy is coming from the energy that is chemically stored in the metal, not from the fruit itself. You should explain this as part of the science project. In that case, you could try oranges, mangoes, peaches, salt water, vinegar, carbonated water, and pop. You could measure the pH of the fruit or fluid, and measure the resistance with an ohmmeter. electric generation might have more to do with acidity and resistance than anything else.
There are other ways of generating electricity and I’m not sure if you are considering any of these because you did not specify. You can make static electricity by rubbing different materials together (such as plastic and fur). Electricity can also be generated from food by making fuel such as ethanol out of it, or burning it directly as biomass. Any food will do this, but might be hard to do as part of an experiment.
If you give more details about exactly how your are making electricity maybe we can help you more.
Edit:
I’m still not exactly sure how you are planning on doing your project. Electricity for home use is produced by generators. Generators require a power source to turn them. Usually this is done with turbines. Turbines can be wind or hydroelectric turbines, or they can be steam powered. Steam power can be run by anything that burns or produces heat: coal, wood, food, alcohol from food, leaves, fibers, grass, etc. Steam turbines can also be run by nuclear energy. You would not be able to actually run these as an experiment by yourself, however, because it would take a lot of time money, and safety precautions. Even a homemade wind turbine would be expensive to make. As an experiment, however, you could burn a number of different materials to heat a pot of water and see how much heat a certain weight of each material produces.
If you are trying to actually power a lightbulb by yourself for your project, you have fewer options. use an array of solar cells. You could use a bicycle powered dynamo (small generator) to run a light–which is ultimately powered by the food you eat. Lastly, you can make your own battery. That’s what I was tryint to explain above with sticking two metals into a fruit. Basically you need two metals (like two coins of different type) and an electrolytic liquid (which helps if its acidic). Most of our household elecrolytes and acids are food-grade, but you can use battery acid which can be bought at the hardware store. Look at the wikipedia article about homemade battery cells. The problem with homemade batteries is that they are very inefficient and you might have trouble powering a lighbulb with one unless you hook up a whole bunch of them together.
you just need to connect an alternator or generator
what size, how much power, what speed…?
you need to give much more details for the calculus
here is an example
http://www.instituteofjamaica.org.jm/NHD/December2008_files/image076.gif
the alternator has to be designed to operate at the turbine speed, and the turbine has to be designed to deliver the torque the alternator requires.
and so on

Hydroelectricity makes use of conversion of water’s potential energy into mechanical energy to turn generators to generate electricity.
A dam stores up the potential energy of the water and the flow from the dam provides kinetic energy for turning the generator.
You need to attach paddles to the motor shaft. Cause the water to flow against the paddles, like a water wheel. Electricity will be generated by the motor.
At 50Hz,
3000 rev/ min for a 2 pole generator
1500 rev/ min for a 4 pole generator
At 60Hz,
4600 rev/ min for a 2 pole generator
1800 rev/ min for a 4 pole generator
These are the common speeds.
