Executive Summary about Solar Cost by Anthony Dempster
Solar power for homes is becoming an increasingly popular method of powering some or all of your house. However many people ask the question “How much does home solar cost?”
There are two main methods of getting your house up and running on solar power electricity. Simply put, they are either professional installation or “do it yourself” (DIY) solar panel installation.
What’s the real truth behind all those ads?
Just searching around online for information about solar power, solar energy, and installing solar panels on your own home, you’ve probably run across many claims which say you can earn money from solar power. So is it true? Yes… sort of.
Executive Summary about Wind Generator by Donald Whitehead
Renewable energy! There is renewable energy for homes for instance, it can range from solar power by use of solar panels, or wind power by use of wind generators both of which there are plans for. This article’s main focus is on wind generators and wind generator plans. A wind generator generates electrical power using the wind as it’s power source. Coupled with solar panels wind generators are the #1 pick for renewable energy for a large array of reasons. Wind generators, unlike many electrical projects, are very basic and can be assembled and installed by most home owners themselves. You can then purchase adequate solar panels as well as the right generator for your wind generation build.
One of the things that a potential obstacle in the development of solar energy is limited space. All existing solar panels in a solar power generation should receive sunlight for at least the same intensity to produce electrical energy optimally. Therefore, all the solar panels should be installed in rows, which mean that also require large open space.
In addition, the performance of solar panels that are widely used today are still influenced by the temperature generated by the environment and direct sunlight. The higher the temperature, the performance of a solar panel will also decrease.
In recent years, Google invest in green energy sector seriously. More than US$ 250 million invested by this company and there is no clear information about why the company’s biggest search engine in the world invest in this sector in addition to its commitment to encourage and develop green energy more quickly.
Google company may not only “simply” investing. The company has a team that is able to analyze and predict the future of this sector.
This time Google reinvest US$ 168 million in a solar thermal power plant located in the Mojave Desert, southeastern California, USA.

Solar energy: this term basically does not cause a stirring in the mind as the explanation that comes at hand is indeed too simple. Everyone knows what is meant by solar energy, and that is, the energy that comes from the sun. In its most basic sense, solar energy and other solar residential equipment are nonetheless environment-friendly and not risky at all. But then you need not become one fine environmentalist first before you will be able to come across with whatever advantageous benefit solar residential energy has.
Why is the solar residential energy said to be environment-friendly? What are its general benefits? Practically speaking, when solar residential energy is used, the electrical bills tremendously go down as compared to the other type of residential energy available for all people. Why would you pay for such expensive bills when all you need to do is to employ solar residential energy?
Another major advantage of the solar residential energy is the absence of the very complicated and dangerous wiring. Solar energy lights in the garden path or any other solar energy-powered items used in your residential are ready to be installed less the wiring to be dealt with. In reality, these solar light bulbs are equipped with darkness sensors so they need not be turned on to give off light and they need not be turned off as well when they are no longer needed.
As a sort of simple explanation, the solar light bulbs will simply have to be purchased, taken out of the boxes, installed, and then presto! You just have to situate them where you want them to be and never worry about them ever again.
A List of the Benefits of Solar Residential Energy
Why is the solar residential energy equally beneficial? Why is it more recommended for use? Here are some of its benefits which are truly worth the attention to be graced by anyone:
Solar residential energy is environmentally friendly. As mentioned a while ago, solar residential energy will not harm the environmental features. It is specifically clean and renewable as well. More so, it does not cause pollution just like what the rest of the traditional electrical forms do.
Solar residential energy systems need the least maintenance. They are not fuel-powered so no need to buy the refills.
Solar residential energy makes you save a lot of money. The energy that is derived from the sun can be accessed for free as you make use of solar lights, solar panels, and the likes. The federal government most of the time gives out financial incentives. You don’t get affected by the rise of the fuel rates since you are using solar residential energy.
Making use of the solar residential energy makes you entirely independent from the foreign and centralized energy sources. Power outages will not likely affect you in any manner.
Most of the solar energy items are very easy to install thus lessening the complicated work of the wiring systems.
Some Common Disadvantages of the Solar Residential Energy
Of course the disadvantages will not be taken aside. Here are some of the most common disadvantages of the solar residential energy:
The employment of a solar residential energy can be expensive at first. But as time passes by, it becomes light to the pocket.
The strength of the solar residential energy will relatively depend on the location of your residence in relation with its facing to the sun. Also, the area of your residence is another point to consider. You will need large areas to install the solar panels.
The Various Solar Energy Items
There are lots of solar energy devices that you may opt to buy. Included are the solar flashlights, solar heaters, car ventilators, solar video cameras, solar radios, solar pool purifier, solar mosquito inhibitor, solar lighting, and solar fountain pumps.
What You Must Do
Back in the earlier years, solar energy powered devices were very costly that very few homeowners made use of the solar residential energy. But these days, small volumes of solar energy devices are put up for sale therefore making it affordable for all. If you don’t have enough money to fund these items you can always start small.
Many people, especially those who are beginners in solar technology may wonder how solar panels work. But first, what is the home solar panels? This is a solar-powered gadget that collect and use the energy from the sun through its rays and convert it into power.
Some people use solar panels home gadgets to act as an alternative source of energy for their small household, effectively complements the consumption of electricity from local utilities.
There are still homeowners who invest in residential solar panels are fully able to provide power to the house, run all appliances, water heaters and swimming pool. However, the cost is very expensive if you intend to own and install your own home solar panels that will work as the only source of daily strength. A solar panel unit actually has a very high price from a few thousand dollars.
How solar panels work can be answered simply. He has a photovoltaic cell in a panel that primarily works by collecting energy from sunlight that falls on them, then solar energy is converted into electrical energy for use at home.
You may very well consider this gadget as an investment, because you need to shell out large enough amount of money to buy and install them as your resource. It is a serious investment even if you only need to spend the money early, the amount needed is really great. After purchase you do not have to worry about this as the sun runs his own gadgets, making endless supply of electricity to your residence with the help, of course, the sun.
Many supporters of a clean environment and recommended the use of green house solar panels, if only because the energy that collects and converts power from the sun. Therefore, the power generated is clean and not harmful to the environment of the world. Likewise, you do not have to worry about running out of the sun’s energy for endless supply. Solar energy is a clean renewable energy, and is considered the best alternative energy is there.
Did you know you can cook entire meals without any electricity or gas? It’s true. If you have access to the sun then you can cook with it.
Cooking with the power of the sun is commonly referred to as solar cooking, and you don’t need expensive gadgets or equipment to do this successfully either. Solar cooking requires sunlight of course, a bit of time, a few everyday items, and a willingness to experiment.
In the most basic form, solar cooking can be done easily as long as you have decently strong sunlight for a few hours. The stronger your sunlight is of course, the easier your solar cooking will be. In the desert southwestern areas of the United States for example, you can literally just lay food out in direct sunlight in the summer and it will cook quickly for you. We’re going to look at a little more than the basics here though.
There are two primary ways to cook food with solar power. One is to use what’s known as a parabolic cooker, and the other is to simply use reflecters.
A parabolic cooker is actually just anything you have on hand which has a slighly bowled, or parabolic shape to it. Round satellite dishes are excellent examples of this type of inward curved surface. The slight curve of a surface like this will allow you to concentrate the natural heat of the sun onto the food you’re cooking.
Parabolic cookers can be made with simple cardboard, or any slightly concaved material such as an old (small) sattelite dish, a small wok, or even a bent and curved trash can or barbecue lid. Using old materials for this is great because it allows you to recycle and it doesn’t usually cost a thing.
Most people choose to make their first solar oven with cardboard because it’s readily available, easy to work with, and free.
The best parabolic solar cooker will have slanted sides though, not upright ones. A slant of about 60 degrees outwards is ideal. Once you find the object you plan to use for your solar cooking, then you simply cover it with tin foil, mylar, or mirrors. Mirrors can actually be dangerous because too much heat is generated, so it’s best to start with aluminum foil. Cover your concaved object with the foil so that the shiny side is facing out. This will capture more of the sunlight shining down on your solar cooking, and help focus it onto your food.
Simple reflector style solar cookers are another popular option, and in many cases you don’t even have to put things together to make this work. With this style of solar cooking, you simply put a pot or pan out into direct sunlight and surround it on three sides with reflective material to help direct the solar heat to your food.
With either solar cooking design though, you’ll want to use either glass or dark metal cooking pots and pans. Dark metal helps attract and absorb the natural solar heat from the sun, and glass allow that solar heat to pass through easily yet stay trapped inside for cooking.
Depending upon the strength of the sunlight you have available and the solar cooker design you’re using, it can take anywhere from one to three hours to fully cook common meals for three to five people.
Of course you can also use regular solar panels or a solar power generator kit to power a more conventional energy efficient stove or oven when the sun isn’t strong enough to use your solar cooker, or if you prefer to cook foods in a more traditional manner.
In general, energy sources are categorized into two parts namely non-renewable energy and renewable energy. Fossil energy sources are among the first group that the bulk of activity in the world using these conventional energy.
It is no doubt that the solar photovoltaic is one source of environmentally friendly energy and is very promising in the future, because there is no pollution produced during the process of energy conversion, and more widely available source of energy in nature, namely the sun.
Fundamental issues in solar cell technology is a very low efficiency in turning solar energy into electrical energy, which to date the highest efficiency can be achieved no more than 20%, and even then in a laboratory scale.
For that in developed countries, research on solar cell is a very big concern, especially with the issue of environmental clean.
From light into electricity
In a simple solar photovoltaic consists of the p-type and n junction semiconductor material (pn junction semiconductor) that if by the sun there will be a flow of electrons, electron flow is well known as the electric current flow. While the structure of the solar cell is as shown in Figure 1.
Figure 1. Structure of a thin layer of solar photovoltaic in general
The main part of the energy changes of sunlight to electricity is the absorber, however, each layer is also very influential on the efficiency of the solar cell. Sunlight consists of various types of electromagnetic waves in a spectrum can be seen in figure 2. Therefore here absorber is expected to absorb as much solar radiation derived from sunlight.
Figure 2. The spectrum of solar radiation
More detail can be explained that the sun consists of a photon-photon, if it happen to solar cell surface material (absorber), will be absorbed, reflected or simply passed (see Figure 3), and only photons with certain energy level that will liberate electrons from atomic bonds, so that electrical current flows. Energy levels is called band-gap energy which is defined as the amount of energy required to discharge electrons out of its covalent bond so that there electric current flow. To free electron from its covalent bond, photon energy (hc/v) must be slightly larger or above than the band-gap energy. If the photon energy is too much of the energy band-gap, then the extra energy will be converted in the form of heat in a solar cell. Therefore it is important to the solar cell to regulate the materials used, namely by modifying the molecular structure of the semiconductor used.
Figure 3. Radiative transition of solar photovoltaic
Of course, that the efficiency of solar cell can be high if the photons from sunlight to be absorbed that as much, then reduce reflection and increase recombination and conductivity of the material.
To be able to make that a photon is absorbed can be as much, then the absorber must have an energy band-gap with a wide range, making it possible to absorb sunlight so energy has a variety of these. One of the many materials being studied are known CuInSe2 is one of the direct semiconductor.
So many advantages of solar photovoltaic as described above was not a polemic and not just stop, saying there was a solar photovoltaic is true when the energy change process there is no pollution produced, but have we calculated how much pollution has been generated in the process manufacturing, small compared to the resulting efficiency. Now the challenge here is indeed how to increase efficiency, which would affect its economic value.
