Solar Panels and Solar Energy

Solar energy collectors are simple structures. Their task is to absorb the incident rays of the sun, and to use the energy to heat water. The simplest systems are in those areas of the world where high solar irradiation is present, such as the Mediterranean region, or India.

Tubes are attached to black sheets of metal, and water is passed through them to a tank. The metal sheet, called the absorber, converts the radiant energy into heat and passes it on to the water. The warm water can then be removed from the tank, and at the same time, cold water is supplied into the system to be heated again. More information on DIY Solar Water Heater FAQ.

Unfortunately, such simple systems are not useful in our latitudes, because of the low solar irradiation; here, the black absorber must be replaced by a flat-plate collector. This is a box-shaped device in the middle of which the collector body is installed. Toward the back, it is provided with an insulating layer, so that heat losses are kept down. On the side facing the sun, one or two glass plates are placed in front of the collector. They make it possible for the system to operate more effectively, because less energy is lost by irradiation when the absorber body is heated. Theoretically, a maximum temperature of up to 120 deg can be achieved with these systems; in practice, however, the temperature is kept down to the level of the desired temperature of the warm water, so that the most energy-efficient operating temperature of the system is 60 deg C.

Although it sounds so simple in principle, it is all the more ingenious in its technical realization. The absorber body and the glass tops are not of simple materials, but are selectively coated so that the absorber can absorb as high a proportion as possible of the spectrum of visible light. On the other hand, the coating helps ensure that radiation losses in the infrared range are not too great, which would reduce the degree of effectiveness of the system. Therefore, an additional selective coating ensures that less us emitted in this spectral range. The same applies to the glass plates glass plates: they are supposed to let the incident sunlight in and reflect as little of it as possible back, and ensure that the infrared radiation reflected by the absorber is reflected back again in the direction of the absorber.

All this is state-of-the-art now, and it makes the collectors technically demanding products, but it also costs money to produce. If all you want to do is hear water for the swimming pool in your yard, very simple systems will suffice, even at your latitudes. Unfortunately, the radiation availability throughout the year is not such that it would be possible to meet our hot-water requirements with solar collectors year-round. Systems with the cost side optimized, for example for a four-person household in a detached home, have a collector area of about 6 sq. m. and a tank with around 300 liters of water content, and can produce enough heat for approximately half our annual hot-water needs. The remaining heat must be obtained via a conventional heat system, either a boiler or else an additional electric heater. This system is sold on the market for about Pounds 5000, including assembly. Assuming a life span of twenty years, a private individual can deduct it at a rate of Pounds 250 per year. A CFO could add the lost interest, since he could have put the money in the bank instead of investing it in a solar system. At the same time, there are savings of about 200 cu.m. of natural gas or 200 liters of fuel oil per year, since the solar energy heats the water. Obviously, this system will not yet amortize itself at the energy price of 90 cents per liter of oil, which prevailed in mid-2008. Nevertheless, some one million solar-heating systems have been installed in Germany alone. A good measure of idealism, and also a government subsidy for this new technology, are the reasons for this market situation.

Using Solar and Wind energy

Solar and wind energy are the most widely used renewable energies worldwide. Solar energy can be converted into usable energy in different ways. On the one hand, the solar radiation can be absorbed by a thermal collector, which then heats a medium, such as water. On the other hand, the photons of which solar radiation is composed can be used to bring charged particles into motion and thus produce electric power in a semiconductor compound. This process is called ‘’photovoltaics.”

In the past, wind energy was used primarily in water pumps – we recall the slowly turning waterwheels in westerns, which pumped water into a tank to supply steam engines. Modern windmills, which drive generators to produce electric power, were developed later. Today, windmills are used worldwide almost solely to generate electric power. Let us take a closer look at these technologies for using renewable energy.

Wind Power
Western Europe is located in a zone of a good supply of wind energy, viewed on a world scale. The kinetic energy of the wind is a function of the wind speed to the third power. This formula means, for example, that the energy content of the wind increases eight-fold if the wind speed doubles. For this reason the best wind sites can be found along the coast or, further inland, at high locations. Under otherwise equal conditions, the difference in wind supply can cause the electric-power yields of a good coastal site and a mediocre inland site to differ by 25%. There are also differences of up to 20% in wind energy supply between one year and another.

Learning How To Recondition Battery

The issue with batteries is that they have a lifespan and as soon as they hit that life span they decrease their capacity to hold a charge for a long period of time. This is why learning how to recondition battery is a growing trend among these communities. Just to clear up a common misunderstanding, reconditioning and recharging are not the same thing, reconditioning a battery is all about restoring the battery back to its full capacity, making like new again, not just putting in another charge for a period of time.

If you do a search online you will find various methods and theories when it comes to reconditioning old batteries; however there are really only two main effective methods. There are mechanical device you can purchase that assist you in the battery reconditioning process and other people say you can simply make the devices yourself and save yourself even more money.

The methods used will largely depend on what type of battery you want to recondition. Almost every kind of battery can be reconditioned however the correct understanding, knowledge and safety equipment should always be used as batteries do contain dangerous chemicals.

Old car batteries are the most popular batteries to be reconditioned, you can usually pick them up really cheap if not for free, they also offer a long lasting charge if you are looking to replace your home energy bill from the main grid.

Many people once they learn how to recondition batteries they often help out others by reconditioning their old batteries and make some extra income on the side. You can help the environment and make money at the same time. Learn how to improve battery life today!

Designing Home Solar Power Systems

There are seven steps in designing a successful solar power installation:

• Scoping the project
• Calculating the amount of solar energy available
• Surveying your site
• Calculating the amount of energy you need
• Sizing the solar electric system
• Component selection and costing
• Detailed design

The design process can be more complicated, or simplified, based on the size of the project. If you are simply installing a shed light for instance, you can probably complete the whole design in around twenty minutes.

If, on the other hand, you are looking to put install a solar power system in a business to provide emergency site power in the case of a power cut, your design work is likely to take considerably more time.

Whether your solar power system is going to be large or small, whether you’re buying an off the shelf solar lighting kit or designing something from scratch, it is worth following this basic design process to ensure you get the best from your system and to ensure that your solar power systems do what you want it to do.

A word of Warning

In the headlong enthusiasm for implementing home solar power systems, it is very easy to underestimate the amount of electricity you need at this stage.

To be sure that you don’t leave something out which you regret later, I suggest you have a break at this point. Have a cup of tea and then return to the project and review your power analysis.

It can help to show this list to somebody else for their input as well. It is very easy to get emotionally involved in solar projects and having a second pair of eyes can make the world of difference later on down the line. Learn how to build your DIY solar panel today!

Solar Power and Wind Power

Home wind turbines can be a good alternative to solar power, but probably achieve their best when implemented together with a solar system: a small wind turbine can generate electricity in a breeze even when the sun is not shining.

Small wind turbines do have disadvantages however, and are very site specific. Compared to large wind turbines used by the power companies, small wind turbines are not particularly efficient and need to be situated in an area of above average wind in order to generate reasonable amounts of power.

If you live on a windswept farm or close to the coast, a wind turbine can work well. If you live in a built up area or close to trees or main roads you will find a wind turbine unsuitable for your needs.

If you are planning to install a small wind turbine in combination with a solar electric system, a smaller wind turbine that generates a few watts of power at lower wind speeds is usually better than a large wind turbine that generates lots of power at high wind speeds.

Grid tied solar power systems are solar power systems connected directly into the national utility grid. During the day, when the sun is shining, instead of storing the electricity, excess electricity is sold to the electricity providers and used elsewhere. During the evening and night, when the solar panels are not providing sufficient power, electricity is bought in from the national utility grid as required.

Grid tied solar power systems effectively create a micro-power station and electricity can be used by other people as well as yourself. Owners of grid tied solar power systems get paid for each kilowatt of power they sell to the electricity providers.

Because a grid tied solar power system becomes part of the national utility grid, the system will switch off in the event of a power cut6. It does this to stop any electricity flowing back into the grid – which could be fatal for engineers working on repairing the fault.
