Solar Power Facts

More and more people are making the move towards using green energy sources now that the gravity of declining availability of fossil fuels is finally hitting home.

Here are some interesting facts about solar power that may help you with your own first step.

1. The Earth gets more energy from the sun in a single hour than the global human population could use in an entire year!

2. Solar radiation reaches the Earth’s orbit at a rate of 1,366 watts per square meter. This number is called the “solar constant”. However, roughly 25% of this energy does not make it through the atmosphere leaving about 1,000 watts per square meter arriving at sea level.

3. The average solar power received on land is still lower. In North America, for example, the average power of solar radiation striking the ground is between 125 and 375 watts per square meter or between 3 and 9 kilowatt-hour (kWh) per square meter per day. (A kilowatt-hour is the energy of 1,000 watts received or generated over a period of 1 hour.)

4. The energy output of a 1 kW solar energy unit is roughly the same as burning 170 pounds of coal.

5. Solar energy is not just about the generation of electricity. The sun can be even more easily used as a source of thermal energy.

6. Solar thermal and solar electric power together can be used for heating, cooling, lighting, cooking, communications, and many other applications. It is very versatile. Many people start out with a smaller solar emergency power backup system, especially useful if your area gets blackouts.

Facts about Solar Energy for Your Home

1. You can store energy in a battery for use on overcast days. Obviously, the more batteries in your system, the more energy you can store.

2. In some places, the local or federal government will give a tax credit to homeowners who install solar systems.

3. The additional energy generated by your home solar power system beyond what you can use can be fed back into the local electrical grid giving you credit from the electric company. This credit is available whenever you need to draw electricity from the grid during nights or periods of poor weather.

4. Solar power systems typically take 3-5 years to regain their costs. However, the savings will be seen right away. If the units are installed professionally, about half of the cost may be recovered through federal support programs.

5. The economics of solar power are sufficient for most locations in the United States to justify the system. In some cases it is better to build your own panels; in other cases it is better to purchase them commercially.

6. A typical solar panel is made of about 40 individual solar cells. The cells are mounted on a board. A one-kilowatt system will take about 10 panels, which is the equivalent of about 400 solar cells. If you are starting from ground zero, this free Basics of Solar Energy course will help.

7. A typical American home uses 920 kilowatt-hours of power per month. Since most electricity generation plants burn coal, which is approximately the same as 770 pounds of coal.

8. The one-kilowatt home system can produce enough energy to prevent the burning of more than 150 pounds of coal per year.

All About Solar Micro Inverters

Solar power technology has a new supplement to its wide variety of selections. We now have what we identify solar micro inverters. These components deeply simplify the installation and monitoring of grid-connected solar panels and enhance the competency of the whole array as well.

Generally solar systems would operate one large, centralized inverter box to transfer from direct current or DC (these are what the panels create ) to alternating current or AC (what most buildings and appliances utilize ). Before sending the energy available to the trunk line or home connection, these micro inverters can be used by every panel to convert its own power before sending it to the particular locations.

This individual panel setup allows for easier monitoring of each panel on its own – to check for competency and problems – and also allows the system’s caretaker optimize each panel and inverters settings to maximize output.

The overall system performance of the solar production can be affected by loads of little things. Things like mis-matched component, unnoticed shading, dust and debris, or even the slight changes in the minute of angle for every panel or array can change the overall power production of the system.

Individual panel monitoring allows for those doing repairs or monitoring the system to know when leaves, dust, or other things are preventing the potential of one or more panels in an array. Faulty components, a loose wire, or other problems are easily detected because of the system. Better repairs which results to better performance can be anticipated with the factors that this system brings.

The solar micro inverters can do things like employing point to point tracking in the panel as a whole and on for each module in a panel. This can show you in detail where the shading might be occurring on the panel, where maintenance might be an issue, or where a damaged plug or cell is located.

As you gather more data, you can have less guess work that can result to improved production estimation and alteration . Attempting to calculate the total size necessary to meet demands specially when constructing a system entail a more specific estimation to work.

Consistency is also one of the advantages of these solar micro inverters. If one break downs , the rest of the system continues to work whereas with a centralized inverter, if it break downs , the entire system is down. Those who intend to rely heavily on their solar power system for their electric needs can use this fact as an important consideration.

Solar array that uses solar micro inverters can be expanded substantially not like those who don’t use one because no replacement of a central inverter is required. This is because as you add a new a panel, you are also adding a requisite inverter. This means a lot in terms of savings compared to replacing your inverter each time.

These solar micro inverters can greatly change the photovoltaic industry and home solar projects — in a good way.

How To Build A Wind Generator

First, something grasps the wind, then a beam is turned that powers a generator then produces energy; these are the three segment of an airstream generator if listed down.

It brings power to our lives, we may have conversations on our telephones and operate our computers as the motorized force of airstream is converted into electrical energy by these three simple things .

You can assume that you can , with no trouble, easily build one foryourself, specified how effortless they are. If you think this, you’d be right . It is not as complex as it might appear . You only [require at least 2 free days, simple apparatus and parts that could be at least foraged, built or acquired easily .

The tower and stabilizers, and the authentic generator are the two division of the job. You won’t partake a difficult moment making lots of assembly since they are so easy, not to mention they are very on hand.

It is favorable to utilize jigsaw in cutting angles as well as thin-blade saw. Hand drills and bits, simple wrenches and protractors for measuring angles are also used . If you still don’t have these apparatus,, you can either come across them in an average home garage or you can buy them at thrift stores and yard sales for less than $20.

Almost all of the materials are made of metal, but no welding or torch cutting is needed to do it. You might like to make a basic protective jacket for the turbine that is a generator itself. If you have some pipe, a box, or anything else into which the generator could be inside, then there’s your solution . An (an electric motor and generator are the samething, the dissimilarity is the tract they revolve to, hence, the generator itself could be a purpose-built or a motor running in opposite . These can be purchased or scavenged. The size of the generator would decide your poweroutput, you must choose for the finestvolt:RPM ratio you can have because bulkier performs more superior. 30V to 325 RPMs are the least production first-rate generators can do.

Once you obtain the motor in hand, you determine your shaft circumference . The dimension of the tube extension and the middle hole for connecting the blades could also be determined . For best results, sheet metal, aluminum, light steels, and the likes should be the component of the blades themselves . Metal is easier to work with in making the bends you’ll need to form the lift that turns the blade. Alternatively, you may find blade at a junkyard or a store that will function. You can also have blades that are suited for this from large-scale model planesand some decorative patio fans.

When it’s all are combined, the blades should be steady completely on the beamso there is little or noinstability.

The container into which your generator matchs should need a way to be organized to a tower. It ought to also be able to spin 90 degrees in both peripherals (or a sum of 180 degrees). This will eventually make the best use of the RPMs because you can place a tail (similar to a weather vane) to spin the fan to the airstream

The loom itself needs to be sturdy and grounded. It ought to be strong enough to keep the windmill in the air and keep the airstream generator elevated (higher is best in almost all states20-50 feet is average for best results) . To prevent it from electrocuting anyone nearby, or from igniting after lightning strikes, it must be grounded electrically .

I have given you uncomplex and general directions, now you are ought to look for someone with mechanical background and observe how simple for them to assemble it in few hours . Inspect uncomplex current – windmills would be producing out DC power; charge controllers, batteries, and inverters, once everything is assembled . This won’t be a dilemma for you if you can wire a stereo for your car.
