Save Electricity With a Solar Water Heater

December 28th, 2009 admin

Being able to use the energy from the sun is nothing new as solar water heaters have been available for use since the 1800?s. Back then it was passive solar heaters that was in use. Now you have a choice of the passive or active heaters for use in the home and commercial buildings.

The passive heater is the most simple to install and use as it has no moving parts. The active requires some electricity to power a pump and controller. The use of solar energy can meet all or part of the homes hot water needs. The geographic location of the home will determine how much it would benefit and what kind of solar heater would be best.

A hot water system would consist of a holding tank and a solar collector to collect the suns energy. A passive system would have the holding tank as part of the collector or located up higher. In areas with no problems of freezing a batch type of heater could be used. These will heat and store the water in the collector. With the passive system the hot water will flow up and the cooler water will stay lower just like hot and cold air.

Most collectors have a flat copper plate that is painted black with tubes attached to it. The plates absorbs the solar energy and transfers the heat to the water that is flowing through the tubes heating the water. The plate is mounted in a case or box with a clear cover like glass that helps intensify the radiation much like the inside of a car in the sun.

Go Green With Solar Panels

December 19th, 2009 admin

Solar panels are gaining interest amongst people of this energy crunched world. What are solar panels? They are an array of photovoltaic cells which capture the energy of the solar rays. In simple terms, the solar panels capture the energy from the sun during the day for later use. Solar energy is renewable source of energy and does not get depleted like coal or natural gas. It can be tapped as much as required and used to power all our energy needs. With the invention of solar panels, which has helped mankind tap the solar energy, solar power has become an increasingly powerful source of energy in the last decade or so.

Solar panels are made of crystalline silicon and gallium arsenide. The same silicon is used in the microprocessor chips. The gallium arsenide is very expensive which also makes the initial investment cost of solar panels high. These panels harvest the solar energy and convert it to electricity. The electricity produced depends on how much of energy is harvested. Roughly, a solar sell of 0.2 m in diameter can create electricity of 2 amps of 2 volts when exposed to direct sunlight at the surface of the equator. However, the electricity production is decided not only by the size of the panel but also by the quality of materials used in making the solar cells. With time as well as with wear and tear, the electricity production capacity of the solar cells comes down.

The solar panels are environment friendly and cause no pollution while producing the electricity. It also causes no imbalance to the eco system. The electricity generated by the solar panels can be used to power a whole lot of appliances. Solar power is very commonly used for lighting needs. Solar panels are also extensively used on satellites. Solar energy is a clean source of power for all needs, having no impact on the environment.

Solar power and solar panels are the energy solution for the future. The conventional sources of energy like fossil fuels and natural gas are fast depleting. To meet the energy demands of the future, we will have to make use of cleaner and renewable sources of energy like solar power. The solar panels relieve you of the dependence on the power grid altogether and can meet all household energy needs.

The smaller solar panels are portable and can accompany you in all your travels. These are very handy when you do not have access to other sources of electricity to power smaller appliances. Hand held devices, laptops, calculators and small motorized vehicles run well with the portable solar panels. There are endless applications for the solar panels if you decide to use them.

Solar panels can be purchased from various solar panel producers and distributors. The price varies and is mainly depending on the power production capacity of the panel. These panels are generally installed in open areas like the roof top or open ground to tap maximum direct sunlight. The location of the panel should be such that it is exposed to maximum sunlight all through the year. Proper selection and installation of a good solar panel will ensure that all your energy needs are met.

The high investment cost of solar panels has dissuaded many people to go in for them. However, the cost alone should not be the deciding factor while selecting a means of electricity. The solar panels produce no toxic gases or products in the generation of electricity and helps keep the environment clean and unpolluted. Using solar panels is the least we can do to protect our environment and make our earth a better place for future generations.

How Solar Water Heaters Work to Save You Money

November 17th, 2009 admin

Like the name implies, solar water heaters use energy from the sun to heat water. Initially, the cost of a solar water heater is high, but it can save you thousands of dollars in the long term. In this article, we’ll discuss the costs associated with solar water heaters, how they work and how to install them.

While solar water heaters are no longer supported by tax credits, they have become considerably more reliable, less expensive and more efficient than the popular models of the 70s and 80s.

For example, a moderate climate system that’s capable of heating water for an entire household can be installed for anywhere from $2000-5000, making solar water heaters very competitive when compared to traditional electric and gas heaters.

What’s the Annual Tab?

Typically, a solar water heating system has an annual operating cost of only about $50. Meanwhile, a traditional gas or electric water heater will cost you $500 and more – especially those that heat up the water all night while everyone sleeps.

Essentially, solar water heaters work by serving as a preheater for a conventional storage or on-demand water heater. They even work well with on-demand water heaters that have temperature adjustability.

Because the solar system preheats the water, the extra temperature boost required by the on-demand heater is low and people who use them can get a high flow rate and lots of monthly savings.

Installation Considerations

Those of you thinking of installing a solar water heater will have at an advantage if you have a south-sloping roof. This will make installation easier and your heater will run more efficiently. Most cold-climate families use solar as a three-season system and then fall back on a traditional water heater during the dark winter months.

Before installing a solar water heating system, always look for a qualified installer and dealer who can design and size your backup system. Ask about their certifications, and request referrals from past customers. This will be a fairly expensive job, so you don’t want to be shy about insisting upon an experienced installer with positive customer feedback.

Thinking Ahead

You should also start planning now. Like most people, we don’t think about replacing our water heating system until it actually fails and hot water becomes unavailable for several hours. In fact, depending on the design of your home water pipes, the main water valve to the entire house may need to be shut off until the water heater is replaced.

Then in those unplanned emergency situations, we wind up rushing out and putting in whatever system we can get. Instead, take the time to research different solar options, find the system that fits your energy needs and plan ahead to replace your existing water heater before it fails.

Remember, most water heaters have a lifespan of about 10-15 years, so be prepared. The energy savings alone could pay for that new solar water heater by the time the year is up, and you’ll be happier knowing you’re polluting the earth just a little bit less.

Solar Water Heater Saves You Money

October 29th, 2009 admin

Are you considering installing a solar water heater for your home? Solar heaters offer many benefits, but there are some disadvantages as well. Find out if a solar heater is right for your home.


How solar water heaters work?


Solar water heaters work pretty much the same way as any other solar powered device. Solar panels installed on your roof capture heat from the sun, than it is converted into electrical energy. The energy is stored in special batteries and the power is used as it is needed.


Quite often your hot water tank will be on the roof too, to minimize the energy loss. But solar power can be used for instant tankless water heaters as well, as for ones with a tank.


Pros and cons of a solar water heater


Advantages are obvious – solar energy doesn’t cost you anything, so you will be pleased to discover how much your energy bills go down with the installation of a solar heater. Another thing some people might not think about straight away is environmental issues. Using energy from the sun is environmentally friendly, so not only solar heater will save you money, but you will help to save our planet.


The main drawback of a solar water heater is its initial cost. In the past few years the prices on solar heaters went down, but they are still pretty expensive. Another disadvantage is that if there is much snow in your aria, the panels will end up under a pile of snow and won’t work. So you will have to remove the snow build up in order for the solar panels to work properly. To avoid this you can add solar-powered heating strips to melt the snow.


How to choose the right solar system for your home


Solar panels will be installed on the roof of your house. Usually on the side facing south. Luckily the panels come in a variety of colors to fit with the design of your home. You can also find many configurations to help stay within your budget.


One way to get a solar water heater, despite its high price is by starting small to reduce a portion of your water heating bills. Then you can add panels as you can afford to. How big a heater do you need? That depends on the size of your family and your hot water consumption. Generally speaking one gallon of water storage for every square foot of collector area works best. Another thing to keep in mind when installing a solar heater is that a path from the collectors to the hot water tank should be no more than 40 feet.


You won’t need a new water tank, unless it is too small for your family. In this case an additional tank can be used. Usually for a 50-gallon water tank 40 square feet of solar panels will be sufficient.


Solar water heaters are becoming increasingly popular these days, because more and more people want to use the energy of the sun instead of electricity or gas. If you get a solar heater for your place, it will eventually save you a great deal.

Homemade Solar Panels Will Slash Your Monthly Electricity Bills for Good!

October 29th, 2009 admin

Solar panels are not some new concept, but building your own Homemade Solar Panels is a new concept for some. It is, however, a quickly-spreading innovation.

Homemade solar panels are a feasible way of generating electricity from energy provided by the sun. By using energy created from homemade solar panels, which would otherwise be wasted or left simply unused, we can provide solutions to a large number of problems, such as the expensive rates charged by electricity companies. It also helps solve problems associated with environmental pollution.

Types Of Solar Panels

There are two types of Home Solar Panels: the ones that heat the water or any other fluid, and the ones that collect energy from the sun, transforming it into electricity. The first type of homemade solar panels is also known as photovoltaic panels or photovoltaic modules, meaning the conversion of light into electrical volts.

Homemade solar panels have been developed in the field of technology and research which is related to the conversion of sunlight directly into streaming electricity. Because of the growing demand for renewable sources of energy, many people have considered the construction of homemade solar panels and photovoltaic arrays in the last few years.

Solar Energy By Numbers

More and more households are turning to build their own homemade solar panels and solar cells. In fact the number of households that are doing this has increased by an average of 48 percent each year since 2002.

At the end of the year 2007, research has shown that the cumulative global production of all panels was over 12,400 megawatts. This energy production can easily lower environment damages as well as our energy bills. So there is an important choice to be made – one which must be made now, while there is still a chance to save our planet and save our money.

Professionally-Made Vs Homemade

Professionally manufactured solar panels are expensive and not everyone can afford them. That’s why homemade solar panels are fast catching on as a worthy alternative. With homemade solar panels, you can greatly reduce your monthly energy bills, leaving you with extra money you can spend on other important things in your life.

Homemade solar panels are relatively easy to build, and the effort is worth it. Even a layman could do it, if presented with step-by-step instructions and illustrations. Materials and tools are ones most people have already around the house. What really helps is that there are many manuals available on the internet that will guide you through the entire process of building and installing your own homemade solar panels.

What Will It Cost Me?

Building your own solar homemade solar panels will set you back by $200 at most – significantly lower than what you can expect to pay for a commercially purchased system; it might be even less if you consider using salvaged materials or parts lying around your house or in your garage. Most homemade solar panels, if well-installed, can easily last twenty years or even more. This is a wise long term investment as you will recover your investment cost very quickly.

So why wait? You can build your own Homemade Solar Panels and slash your energy bills for good!

Why pay your power company hundreds of dollars each month… when you can easily build your own Home Solar Panels and generate the same electricity for FREE?
