How Does Solar Energy Function?

February 23rd, 2010

Nowadays , most people want to save money on their energy bills and one of the more popular ways is through using solar energy. So how exactly does solar energy work? To know more, go to solarpower

Energy from the sun in the form of heat and light is abundantly accessible to everyone on Earth, even in areas that don’t get a lot of sun. Are you aware that the Earth receives a lot more power from the sun in an hour than our whole human population can use in an entire year? With all that clean, renewable power that is coming from the sun every single day, it’s worth it to figure out ways to utilize it.

Active Solar

There are 2 various kinds of solar power you can use to power our homes as well as day-to-day lifestyles. The first is active solar power, that works through solar panels, which are setup with the use of photovoltaic cells. These types of cells are linked together so that you can generate power.

Just how much electrical output they will generate depends upon a few factors. One of them is the number of cells are connected together in a panel, and how many panels are now being utilized.

The energy from the sun comes as direct current, DC, rather than the alternating current, AC, which is used in your house. For this reason you will need ways to convert the energy. The simplest option would be to purchase a power inverter, which usually convert the sun’s energy in to usable AC elecricity. Another option is to convert your house’s electric needs to DC power, though this is in most cases impractical especially in existing homes.

Thermal Solar Energy

There’s one more form of active solar power that uses thermal energy from the sun’s rays to heat the water in your home. Devices that circulate as well as pump the water help to keep it warm. Depending on where you live, solar power could heat water as much as sixty degrees or even more. While this may not be ideal for taking a shower, it may be effective for dish washing or perhaps doing your laundry. Solar power for warming water may reduce your water heating bills substantially, and also may be used in combination with solar electricity.

Passive Solar

Passive solar energy uses the power of the sun without having the use of any mechanical devices. When you’re out on a sunny day, you are feeling the warm sun’s rays, and this process is actually similar for heating your house. A passive solar home has south facing windows and also makes use of building materials which absorb the sun’s rays after which dissipates the heat in to your home efficiently. Passive solar may also be utilized to heat water in our house.

Using Residential olar Energy

Solar electricity is a good option to powering your house with standard power grids. It is already being utilized in a number of residential, as well as business applications globally. There are lots of various methods for you to obtain a home solar power system, including DIY solar power kits which come complete with diagrams and materials you need to construct your own solar power systems for very little money.

You may also find solar energy professionals which will come to your home, evaluate your needs, and accomplish all the work for you. There are also ways that you can get used solar power panels at no cost, or through solar energy grants or renewable energy programs in your area.

You are able to run your house on solar power even if there is minimum sun. Utilizing batteries to store excess energy, you are able to draw from these through the days when there’s simply not sufficient sun to be effective.

What Home Solar Panels Can Be Used For

February 13th, 2010

There are various different uses for solar panels. Solar panels for home applications will be in 2 completely different types, ones that absorb the sun’s rays with photovoltaic cells, for electrical purposes, and a few that are used to heat water. Both solar systems will save you a lot of cash in the short term, yet as the long run. Solar electrical power systems have many advantages. They’ll relieve some pressure off of using your power grid, saving you plenty of cash when the sun is out. With the proper battery keep a copy, you will even have power at the hours of darkness, or when the grid is down. Several people use solar electricity to utterly run their entire residence, fully looking forward to renewable energy.

Solar panels for home use will additionally heat up your water supply, saving you money. In colder locations, where the temperature of the water table is below sixty degrees, using solar can heat up water to a higher ambient temperature. This will relieve a number of the pressure on hot water heaters, as a result of it does not take as much to form water hot. For ambient temperatures on top of sixty degrees, and where you have got ample daylight, you may even be able to induce rid of your water heater completely. Even just heating the encompassing water temperature can lower your heating bills by up to 40-60%. Rather than solar panels having a photovoltaic cell array, they have a series of pipes running through the frames. As the water passes through, the warmth of the sun, and therefore the type of piping, heat up the water. If this water is pumping through consistently before feeding into the new water intake, the hotter it can be.

Solar panels for your home do much additional than just heat water and generate electricity. Solar panels facilitate to save lots of our planet. For one issue, they use energy that is abundant, renewable, and utterly free. Manufacturing electricity from the sun doesn’t require the employment of our natural resources, and these systems do not offer off any harmful emissions. Whether or not you are still connected to the grid, or totally self sustained, using solar energy will facilitate cut back overall energy usage. This can ease to burden on power plants, several of which still use fossil fuels such as coal and petroleum products to make electricity.

With the proper solar panel power system in place, not solely will it acquire itself in a very short amount of time, however it can indeed truly make you money. How will it build you money? If your system is attached to your grid still, and you turn out more electricity than you can store and use, it feeds directly back to to the grid. You’re basically a little power plant, and by law, utility corporations have to buy this surplus power from you. You have to make arrangements 1st, but even 10 or fifteen bucks a month is best than nothing. Many individuals who use solar panels will keep connected to the grid, just to form a very little further money.

To save energy at home is to indirectly save money and heavily reduce home expenditures. Read more at my site:earth 4 energy review for more information about earth 4 energy at home. Learn more about saving energy and acquiring energy efficient homes: earth 4 energy review.

Solar Pool Heaters – Taking Your Backyard Recreation Off-Grid

February 11th, 2010

In 2001, data collected by the U.S. Energy Information Administration indicated that heaters used in hot tubs, spas, and pools accounted for approximately 2,300 kWh of electrical use per household annually. That added up to a combined 7.6 billion kWh in the approximately 3.3 million households where the units were present. At the current national average cost of electricity ($.12 per kWh), that’s about $276 per year, per household. Since it’s safe to assume that the number of hot tubs, spas, and pools in the country has increased over the last decade, that’s a staggering amount of dollars and power going toward heating water.

Solar pool heaters, which are easily priced competitive with gas and heat pump units, can substantially reduce energy use in this area while lowering power bills and offering fewer maintenance issues. Unlike the photovoltaic cells with which most consumers are familiar, solar pool heaters use a thermal solar configuration. Basically, water from the pool passes through a filter to remove debris before circulating through a solar collector where heating occurs. A pump circulates the water, which is diverted back to the pool itself with a manual or automatic flow-control valve. The most sophisticated units include temperature sensing devices that only circulate the water when heating to maintain a pre-determined temperature is required.

These solar systems come in either glazed or unglazed models. Unglazed units work best in regions where the temperature stays above freezing. They consist of heavy-duty rubber or plastic tubing treated with chemicals to withstand ultraviolet light. Glazed systems are protected by an iron-tempered glass covering and are made of copper tubing mounted on an aluminum plate. Equipped with heat exchangers and transfer fluids, these systems capture heat more efficiently during cold weather, but can also be used year round in most climates. They are more expensive, but can also be adapted for domestic water heating. (Note that both types of systems should include freeze protection in given regions.)

Estimated cost of the components and their installation is $3,000 to $4,000 with an expected payback on the investment in 1.5 to 7 years depending on location and annual electrical rates. The systems are largely maintenance free. Washing to maximize heat penetration is recommended and homeowners should consider the caveat that any pump or pipe can become clogged by debris if the system’s filter is breached.

Homeowners interested in solar pool heaters should evaluate their site to ensure that a collector can be placed at the correct angle relative to their longitude and latitude to receive optimum sun. Most likely working in concert with a professional, determine how large the collector should be and investigate relevant local building codes and homeowner’s association covenants before proceeding. The estimated operational life for a solar pool heater is 10 to 20 years, offering an excellent long-term return on the investment in both material costs and annual energy savings.

How Does Solar Power Work?

February 11th, 2010

Solar power became popular when it was first used in calculators where solar cells are used instead of traditional batteries. There were watches too that used solar energy and the advantage of not using batteries created long term savings. Today, solar energy is not only used in these gadgets, the use of solar energy is already possible to power any household. Gardens and pools can also use solar power as a source of electricity for hydroponics or heating, respectively. The reality is here that anybody can take advantage of solar power for the home and contribute to making the environment cleaner and better.

Solar power started with big solar panels installed in California supplying more than 10 million homes in the state. Today, the technology has evolved into more compact and smaller panels that can supply even more homes.

Basically, solar energy is used to derive electricity from sunlight. This can be done directly or indirectly through photovoltaic or through concentrating solar power, respectively. The use of photovoltaic converts the energy coming from the sun and converts it into a clean form of electricity that can power houses. These photovoltaic cells are composed of both positive and negative slices of silicon placed under a thin glass. When the protons of the rays of the sun hits the photovoltaic cell, the neutrons are knocked off the silicon. These neutrons become stored through the magnetic field and are connected to a circuit that forms electric current. Consequently, direct current electricity is generated and the process includes converting the DC into alternating current that is supplied to homes that can power all electrical appliances.

In the conversion process, not all of the converted electricity are caught in the process. There is a small percentage that is lost. But the percentage converted is already enough to supply the electricity needs of homes.

The good thing about using photovoltaic or PV cells is that there is no requirement for maintenance. Since the cells are static, which means there are no machines or moving elements in the system, the cells can last for four decades. The only requirement is to clean the cells annually and everything is considered properly maintained.
Solar power is very useful in household operations. With a grid tie system that you can set up in your home, you can enjoy the benefits of solar power that can help in your electricity needs. With a good roof space, the installation is easy and when you generate more electricity compared to what you need, you can even sell the electricity back. This can mean that you will no longer have to pay for your electricity.

The use of solar power will give many benefits to you and the environment. It is time to consider the installation in your home to contribute greatly to a cleaner environment not to mention the financial impact that it can give to your budget. This is a wise move and with the technology available, there is no reason not to take advantage of this during these trying economic times.

How Efficient Is Solar Power?

February 10th, 2010

You may be in a situation of considering the use of a solar power system in your home because you know that this is more efficient than using the conventional energy source. However, you may be thinking at how efficient solar power is at the technical level. You have to note that the efficiency rating of using solar power can range from 5% to 15% but it can even increase to 40%. This level is enough for the amount of power that you need for your home.

The number of solar panels that you need for your home is determined by the total output wattage that is required to supply the needed electricity. The solar panels have their rating capacities indicated. If a solar panel or cell indicates a capacity of 100 watts, this meant that it will output 100 watts of electricity in the best solar power system condition. A simple computation will lead you to need 10 solar panels for a requirement of 1 kilowatt per hour of electricity. Normally, solar panels are available at a capacity between 30 to 205 watts. With some calculations, you will be able to derive the number of panels you need for your household consumption.

The available roof space has its role in making things possible for you. The size of the roof determines the number of panels that can be installed and since the solar panels determine the amount of electricity that can be supplied to your household, it follows that the less number of solar panels, the lower the level of electricity that can be supplied to your home. As an effect, your electricity may not be enough for all your appliances. Hence, it is critical not to be very particular about cost in having your solar power installed. The cost is directly proportional to the number of panels that will be installed.

If you are very much concerned about the efficiency rating of the photovoltaic cells, you can choose monocrystalline panels for your solar panels. This is the more efficient type and they are smaller. This means they take a smaller space and with a limited roof space, you can maximize the space with the smaller monocrystalline panels. The only trade off compared to other types is that they are more expensive.

It is very important to calculate your energy requirements before deciding on the specific solar power system that you will use. This can be a basis for the most appropriate choice among the different types of solar panels. You can also find good suppliers or providers and you can compare their rates and services. It is also important to be meticulous about specifications because these determine the difference in the prices.

The other factors that can affect the efficiency of solar power system include the maintenance work that is done on the solar panels, the amount of sunlight that is absorbed and how the sunlight is transferred. These are general factors that can affect the efficiency of a solar power system.
