Today, pretty much everyone knows that we need to start focusing on renewable sources of energy and solar energy and solar power is one of the most talked about. Of course, it’s no surprise since using the power of the sun has been around in some form since the dawn of time and there are many benefits of solar energy both for homes and businesses.
One of the biggest benefits is that solar energy is renewable. While it might be stronger in some areas and there could be rainy days when no sun is available, no matter how much solar energy we use, we are unable to deplete the resource, the Sun. This is in sharp contrast to the fossil fuels we use now which are dwindling in supply.
Also, unlike fossil fuels, solar energy does not harm the environment. There are no byproducts of solar energy that leach into the air and create pollution or contribute to greenhouse gasses. In addition, acquiring the power is not intrusive to the environment like some other forms of energy. About the most intrusive part would be the solar panels which are well suited in most areas to fit snugly on the roof.
When using solar energy for your home, you can turn your residence into a self contained unit. While it might not be practical in some areas to rely solely on the sun for power, other, less developed, areas might benefit immensely by being able to power homes and schools with the sun without having to install power plants and run electrical cables. In areas where there is not enough sunlight for household needs, systems can be setup so that you can hook into the electrical grid during those times when more energy is needed.

While installing a solar energy system for your home or business can be expensive at first, you will eventually see a savings because as time goes on you will not be paying that monthly power bill. Additionally, if you are the Do It Yourself type you can easily build the system inexpensively. After the initial costs, gathering power from the sun is free so once you have your collection and storage systems set up, you will be reaping the benefits not only in the monthly savings but also in the benefits to our planet.
Pros and Cons of Solar PowerThe advantages of solar energy continue to grow with more pros and experts learning more about the process and features. Of course, there are also a number of consequences especially for the person who does not study much about the devices. It is important that you weigh the potential of having your own setup. You should consider the things you need to power, your location, budget, etc. Here are some more details about the energy.
The good thing about solar energy is that it can be used anytime or as long as the sun exists. You can get the power you need day in and day out. Solar power is a renewable resource which means that you do not have to pay any bill or keep replacing parts to get the results that you need. The disadvantage in terms of availability is that you cannot access the energy if there is no sunlight. You cannot rely on solar power at night or in places that tend to be very cloudy for several months. People living in tropical areas or desert regions can rely on solar panels. However, those who experience very long winter months may not get the best effects.
Nowadays, solar energy can power a variety of objects such as homes, offices, cars, small light fixtures, toys and calculators. You can now rely on the sun to help you minimize utility and electric bills. You can even see a number of vehicles now solely powered by the sun. The disadvantage to the approach is that the power may tend to fluctuate depending on the sunlight available. Some devices may not work as well if the acquired energy from the sun is insufficient. In some cases, power may totally fail if solar energy is limited or unavailable.
Even though solar cell panels are readily available in most hardware stores and the internet, not everyone is still capable of installing the devices properly. The initial setup costs may be very expensive for some individuals. Women may especially find that tasks hard to do unless they rely on a professional to do all the work. Installation will depend on several factors and will need careful study, such as the angle of the sun, the position and area where you need to place the solar panels and the number of hours to complete the project.

Purchasing solar power systems may be more expensive for first-time buyers. Those who have been used to the old system may have to spend more initially. Overall, the cost for maintenance begins to taper down because the sun is readily available and free. Some people, especially those coming from the third world countries may not have available solar cell panels ready for purchase. They may have to order online. The professionals needed to install and maintain the system may not also be available in some areas. The fees, if ever, might be more expensive. You have to compare the options first.
How To Build Solar PanelsSolar panels use a technology called Photovoltaic (PV) power systems; this is a complete source of electricity that uses solar cells to convert the sun’s rays directly into electricity. To find out how to build solar panels you have to first understand how its system and its components work. I recommend that you read a few books on solar energy and photovoltaic technology.
To find out how to build solar panels you will first need to purchase some solar cells. A solar cell can be cut into the desired size and connected in series with other solar cells that are of a similar size. These cells are packaged with other materials that you will need to protect the cells so that your solar panel can withstand harsh conditions and will still be efficient. For this project buy cells that produce 0.5 volts (V), 3 amps (A) direct current (DC).
You can actually buy a pre-made panel from your local hardware store. All you need to do is tell the customer service sales person what size your cells are, and how big you want your solar panel to be. I recommend that because your cells produce 0.5 volts you should make a panel with 36 cells. Many people ask the customer service assistant how to build solar panels and they respond with “just buy the cells and the pre-made shallow box’’.
The sales assistant will give you the option of either having a glass or pexiglass front – choose the pexiglass because glass is too fragile (and especially since this is your first solar panel project). Now you have the structure of the panel that you have bought from the hardware store, it is time for you to put the solar cells in the solar panel. Draw a grid pattern on the solar panel to see where you are going to put the cells. Then lay them out on your penciled in grid upside down, and solder them on in a series. Next glue the cells in place on the solar panel (only glue the cells in the centre of the cell this is very important).

After you have found out how to build solar panels you are probably wondering where you can actually use them to generate energy from the sun. There are tons of places – these places include on top of your garage, on top of your boat, at your holiday home, at your domestic home, and as a form of garden lighting the possibilities are endless and you will be so pleased that you have built something that can be used for so many purposes.
Many people actually give up on finding the answer to the question how to build solar panels, because after days of tireless searching on the Internet you can never find an answer. This is often very frustrating because you can find the answer to every other possible question. However, there are some really good books (ebooks) that you can buy that give you step-by-step instructions on how to build solar panels. Before you purchase such a book read the reviews and if there are a number of reviews for that book, you should buy it yourself because you never know it could be really good and filled with lots of great information. Remember you always have a 60-day money back guarantee with such products if you are not satisfied.
Renewable energy systemIt is possible to generate electricity by harnessing the best possible use of natural resources. Most renewable energy resources are derived from the sun and solar radiation, such as energy for heating and electricity, as well as indirect forms of solar energy such as energy from the wind and waves, and geothermal energy resulting from the heat generated within the earth.
A renewable energy system is a specific technology that has been designed to make use of these continually replenished resources. There are currently some really good systems in place. However there are still technologies that need further research and development in order to replace a significant proportion of fossil fuel use, and thus reduce the overall environmental impacts from use of such fuels and current energy sources.

The sun’s power can be converted into energy directly using a renewable energy system. There are a number of technologies in use currently, however not too many people are high on the uptake of these technologies. One such renewable energy system is a solar technology called `solar collectors`. These are what are known as active solar heating, where a solar collector is mounted on the roof of a building and gathers solar radiation, and produces heat at temperatures usually under 100ºC.
What is often the case is that people use this renewable energy system for hot water to supply their home for showering and for swimming pool heating. There are a number of energy companies that deal in clean energy who will supply a solar collector for you at a cost, or if you are good with your hands and consider yourself to be a bit of a `handyman’ you can build the technology yourself using materials that you can buy at your local hardware store.
Solar collectors are a very basic renewable energy system. One of the better technologies that make use of the power of the sun’s rays is a solar thermal engine. These follow the same idea as the solar collectors discussed above however the technology is much more advanced and thereby much more effective. This renewable energy system uses active solar heating at very high temperatures in order to drive steam to turbines, in order to produce high levels of electricity. These systems are currently being used but will be used even more in the future when we no longer use fossil fuels as a source of power/electricity.
There are a number of renewable energy systems that use passive solar heating and this is really important because it reduces the energy needed for heating a home/ area. For instance, from a very young age we are told to always open the blinds to let the sunlight in and close them at night just before dusk and before it gets dark – this is common sense, but many people are unaware of the importance of such practices.
A renewable energy system that uses passive solar heating is one of the best ways to take advantage of the consistent energy available from the sun and at no cost. There are many building companies that specialize in low energy building design, that allow your house to make the most of passive solar heating. In order to reduce heat demand, homes are designed in such a way so that the windows let lots of sunshine in and this is especially important during the winter. Homes must also be well insulated and windows double-glazed to keep the home warm in the winter without the need of high levels of electricity. Talk to your local energy company and building company about what you could possibly do to create a renewable energy system that uses passive solar heating.
