Solar Water Heaters: Saving Your Money Using A Solar Water Heater At Home

February 8th, 2010

Solar water heaters or, as they are likewise named, solar domestic hot water devices, can easily be a cost effective way to produce hot water in your house. They have the ability to be made use of with virtually any climate, plus the fuel that they use – sunshine – is 100% free.

The prospective benefits might possibly break down your resistance to the idea of making the investment in a solar water heating system that’s a component of building an environmentally friendly residence, along with other more traditional means of reducing energy costs.

What They are Made Of

Sunshine powered water heating systems consist of storage tanks coupled with solar collectors. There are a couple sorts of these heating devices: active – which include circulating controls and pumps – as well as passive heating systems, that do not.

Passive heating devices are generally less costly than active systems, though they’re commonly not as economical. Still, passive systems may well end up being more reliable and may well last longer. Regarding active devices, you ought to talk over the upkeep requirements together with your system supplier and check with the system’s owner’s manual.

Heading Down the Tank

Nearly all water heaters which operate on sun power need an insulated storage tank. Solar storage tanks include an extra electric outlet and inlet connected to and from the collector. In 2-tank designs, the solar heat tank warms up water just before it goes in the standard water heater. In single-tank designs, the backup heater is joined with the solar storage in one tank.

Electrical Power While the Sun Isn’t Available

Solar water heating systems nearly always demand a backup device for cloudy days and periods of greater need. Traditional storage water heaters normally provide backup and may possibly already be a component of the solar heating package.

A backup system might also be an element of the solar collector, like rooftop tanks with thermosyphon models. Since an integral-collector storage system already keeps hot water as well as collecting solar heat, it might possibly be tied in with a backup water heater.

Up Front Issues to Consider

Prior to when you purchase and install a solar driven water heating system, you need to consider the immediate and ongoing expenses of solar energy devices, examine your site’s solar resource, establish the correct system measurements and power efficiency, and then read your local requirements and polices.

The correct assembly ?s dependent upon your solar resources, climate, community building code standards along with safety concerns. It is advisable to get a qualified, solar thermal systems service provider install your system.

Normal upkeep on simple devices can end up being as sporadic as each 3–5 years, and if at all possible completed by a solar service provider. Systems having electrical components normally require a replacement part after a decade.

The Payback

While you can find limited complications with existing solar water systems, the technological innovation is quickly becoming even better. For a customer, these systems are a wise commitment because they will pay for themselves in a brief amount of time, therefore trimming back on your power bills.

Moreover, several governments provide rebates to consumers who invest in environmentally friendly solar energy systems. While saving money with solar power and other measures to reduce energy costs, you are able to additionally be environmentally friendly simply by decreasing your dependence on fossil fuels.

Versatile Solar Energy – Advantages Of Solar Energy

January 31st, 2010

Solar radiations vary in frequencies from infrared through the visible to ultraviolet frequencies. We receive light through the visible radiations and heat through the infrared radiations. We tend to have been learning currently how versatile solar energy is.

Even in the traditional times individuals made use of the solar radiation for heating water and warming homes in winter. In recent years, thanks to technological advances, solar energy is being used for applications ranging from domestic hot water offer or area heating of large buildings, to providing steam and hot water for industrial processes and for providing steam in giant thermal power stations to supplement power generation.

Modern developments have given a new angle to the use of solar energy. Invention and later developments of photovoltaic (PV) cells has created it possible for us to convert energy from the visible radiations into electricity. Individual solar cells which are little are assembled in various configurations as arrays and panels; these solar arrays and panels will generate sufficient electricity for sensible applications.

Arrays of PV cells are being used in remote and inaccessible communities to supply clean power and they’re being used to run cars. PV cells offer power on satellites and space stations and even supplement power generation in power stations of tons of MW. Growing at a rate of forty% since the year 2000, put in capacity of solar electrical production has touched 10.half dozen GW in 2007.

The above two instances of the use of solar energy are the terribly obvious and terribly a lot of talked about ones. But return to consider it, there’s hardly any renewable energy source that doesn’t link back to the versatile solar energy.

Assume of wind energy. Mild movement of air is breeze; more strong movement of air is wind. Unequal heating and cooling of different components of land and water by solar radiation creates convection currents that end in wind. Windmills are driven by the kinetic energy of the wind. Solar energy is responsible for the heating of the land and the water masses; therefore it’s the solar heat that’s accountable for making wind. So extremely speaking, wind serves just as a carrier of the versatile solar energy.

Similar is that the case with tidal energy. Tides result from the interaction of gravitational pulls of the sun and therefore the moon on the water bodies on earth coupled with the rotation of earth. Once again we tend to notice the sun is instrumental in creating the tidal waves that we tend to are making an attempt to harness to extract energy from.

Biomass is being employed as a renewable supply of energy. A very little thought tells us that the energy biomass gives out is that the solar energy stored in the form of carbohydrates and by burning the biomass – which is burning the carbohydrates – we tend to are releasing that stored solar heat. Once more it is the versatile solar energy in an exceedingly different kind that we are using.

The fossil fuel that we are using in each walk of life nowadays is additionally another example of stored solar energy. Fossil fuel has resulted from animal remains, biomass, etc innumerable years ago. Once once more fossil fuels are a kind of stored solar energy, just as we said biomass is the stored solar energy.

We have a tendency to said at the outset of this text that solar energy is terribly versatile. As seen by these few examples higher than, we tend to have been utilizing versatile solar energy in many forms.

Making Your Home Solar Powered

November 14th, 2009

Many Americans have decided to become more energy independent, and want to play a part in avoiding a very foreseeable energy crisis. They’ve decided to go solar. Creating a solar powered home is an endeavor that requires an initial investment, but the costs are being lowered everyday. Solar power provides long term benefits. Not just for the home owner, but the environment too.

Now that solar power is more efficient, you can reduce or even eliminate your electric bill, increase your home’s value and contribute to a cleaner environment, all at the same time. It’s a great time to join the move to renewable energy resources, and the perfect time to take advantage of the generous government and local utility financial incentives that can cut thousands of dollars off the price. And now that solar power is becoming even more main stream, it is growing in accessibility. Manufacturers of solar powered products have realized the potential for a solar age, and are creating new options for those who are considering a solar powered lifestyle. If you are ready to step into the solar age, you are probably wondering how and where to begin. Below is a list of ways to make your home a solar one.

Solar Attic Fans- Solar attic fans are a great example of a simple way to make your home more energy efficient without spending a lot of money. The need for air conditioning is reduced by venting hot air out of your attic. Installing a solar attic fan may also increase the life of your roof materials by keeping them at a lower temperature which also reduces moisture buildup in your attic. This prevents mold and rot in your home, and can also reduce allergens and pollution.

Solar Heating- Solar heating systems are composed of solar thermal collectors, a fluid system to move the heat to its point of usage, and a reservoir for heat storage. The systems may be used to heat domestic hot water, swimming pool water, or for space heating. If you live in the southern half of the United States or in an equally sunny area you could potentially save between 50% and 80% on your water heating by implementing a solar hot water heater. The initial cost is hefty, but depending on how you use it, the system may pay for itself in as little as five years. The return is greater when you factor in rebates and incentives offered by states and local governments.

Solar Pumps- Depending on where you live, especially in remote areas, the cost of traditional water piping may be exorbitant. Unless you install a solar water pump. A solar power panel collects solar energy and powers a battery which can keep a consistent and plentiful water supply.

Solar Paneling-The most obvious way to break in to the solar age is to install solar panel cells on your roof. Solar cells, also known as PV cells, or Photovoltaics, come in many sizes, colors, and performance characteristics, made to fit a variety of homes and lifestyles. Another important factor to consider is that when PV panels are used in conjunction with energy efficient appliances, not as many panels may be needed to power your home! Large scale home improvement stores, as well as smaller, independent energy groups, offer installation. But if you are a savvy do-it-yourselfer, you may decide to undertake the project on your own!

But don’t bust out the screwdriver just yet. Whether you do it yourself, or hire someone to do it for you, there are a couple of technicalities to be seen to before solarizing your home. Such as building permits. In order to legally install renewable energy sources in your home, you must contact your city or county building permit agency to obtain permission. You will be able to learn about requirements specific to your neighborhood. Don’t forget about property and sales taxes. Depending on what state you live in, you may or may not be exempt from these when it comes to the purchase of your renewable energy system.

Although it is not difficult to keep up your solar systems, frequency of replacement should be considered. Solar thermal systems need valves replaced every 3-5 years and storage tanks replaced every 10 years. Luckily, solar PV systems typically do not require maintenance, other than a yearly cleaning of the solar panels. PV panel life is typically 25 years.

Go Green With A Solar Hot Water Heater – The Best And Most Cost Effective Sustainable Living Option For Your Home Or Business

October 20th, 2009

If you are looking to Go Green, Get Greener, or simply looking to learn more about Solar options for your home or business then you will want to read further. The most cost effective option to incorporate solar into your home or office is to add a Solar Hot Water Heater System. Many people in the U.S. can produce more than half their domestic hot water needs with a Solar Water Heater. In Arizona and other southern regions of the US this can be more than 80% savings.

Solar Hot Water Heater systems can be either active or passive. Most Solar Water Heater systems use a pump to move fluid through one or two collectors. Thermosiphon systems, suitable for simple domestic hot water systems in frost-free climates, rely on natural convection to move water. Panels or collectors are mounted on the roof which are heated by the sun and then heat the fluid which then heats the water in your storage tank. This takes the load off of the water tanks electric or gas heating element because the water is already hot enough which saves you money every month.

A Solar Hot Water system is cheaper than a solar space heating system but still costs more than a than conventional water heater, typically between $7,000 and $8,000. However, after rebates and tax incentives the cost to the client is typically around $2,000 AND includes a new conventional water heater. The major difference between the two being that the solar hot water heater is paying for itself while you will always to continue to pay for the conventional water heater. Solar hot water heaters typically pay for themselves with the savings generated in a few years and then continue to make you money. Homeowners may want to budget for routine maintenance with some solar hot water systems to include periodic checks on the pH of some system’s glycol solution.

A gas water heater should never be used as the only tank in a solar hot water heater system. Electric water heaters do not require an additional tank but you may want to add one for additional hot water storage. In a solar storage tank, water stratifies by temperature; cool water from the bottom of the tank is pulled up to the collectors to be heated and is returned to the top of the tank. The colder the incoming water, the higher the solar collector’s efficiency. In a single tank system, the electric element or gas flame keeps the stored water hot, leaving no cold water available to send to the solar collectors.

In most cases, credits or rebates can defray some of the cost of installing a solar water heater and are available from local utilities or state and federal governments. Solar systems offer stability and predictability when it comes to energy costs and supply. That’s not something that any system running on fossil fuels can match.
