When light falls on any surface, its temperature rises comparing with the surrounding air. This temperature increase is the result of accumulation of heat on the surface due to energy absorption of solar radiation. If a heated surface we’ll have capacity, which will circulate the water, the water will be heated.

Time raising the temperature to the desired level depends on the amount of calories, which receives water from the sun, as well as from the device absorbing elements (solar collectors) and batteries (tank, tank).

Dr. SGAbbott, a pioneer in the study of solar energy, in his book “How to use the heat from the Sun” describes the primitive, but nonetheless a convenient generator of hot water this way: “I bought a 6 m long, black garden hose, wound 4m around a wooden frame and raised the design of the stairs on the south side of the roof of my house. Others 1,5 m I tied to the faucet in the yard and to the faucet in the bathroom. With this simple device on a sunny day we had a very warm 22 liters of water every half hour.

Of course, installation, commercially profitable, now is not so simple. However, they are arranged but the same principle, albeit with much greater efficiency.

Modern solar hot water generators consist of two main parts: a solar collector and the reservoir with warm water. The surface of the collector can heat water from 50 ° C to 80 ° C. In the vacuum collectors with ideal surfaces, the temperature reaches 300-350 ° C. The use of parabolic radiation concentrators allows to reach even higher temperatures. Sun-heated water from the reservoir (55-56 ° C) enters the heat exchanger solar tank (tank), which is heated to the desired use of water (150 – 500 liters). This heating may be different depending on the duration and intensity of sunlight. The circulation of heated water could be due to thermosyphon principle or with a pump, which is controlled by a thermostat, set at the highest reservoir.

Tanks (tanks) may be made of metal or plastic and must be thermally insulated. For industrial purposes, which require a lot of water, use of mass production of tanks with a capacity of several thousand liters. These tanks are suitable for hospitals, barracks, bath houses, campgrounds, hotels, boarding schools, etc.

Collectors may be combined in series, and the daily rate sun-warmed water, thus, will be increased.

8 North Africa and the Middle East are set to give a day 50-100 thousand liters of hot water. Large installation of this kind exist in Europe. For example, the French firm “Sofe has built a highly productive installation at the hotel with 35 rooms and camping. In Bern, Switzerland, operating facility, which produces 9 thousand liters of hot water with the help of 40 m2 surface of the reservoir.

In some Japanese plants solar collectors and tanks, batteries constitute a single system. To ensure that the natural thermo circulation, tanks must be at least 600 mm higher than the upper reservoir, if it is not possible to use a circulating pump. Contact with the house is reinforced by thin copper tubes with a diameter of 30 mm, the use of which avoids the heat. For cloudy days provides electric heating element with capacity 0,5 – 2 kWh, an adjustable thermostat. Tanks and piping work under pressure of about 6 atm., And the test pressure, in many cases equal to 10.12 atm.

So you have to be sure that all fractures and crevices are sealed tight. You can help make your home energy efficient by substituting your lighting fixtures with energy efficient types. You should make use of your dimmer switches also because this saves power and money. Open up your blinds and curtains and let the sun light shine in, this is how you can save the most on your bill and it is the best way to conserve energy.

When you are using your home equipment you are using a lot of energy. The best way to save power here is to shop for new appliances that have the energy star. The cost of these tools may be higher then normal but they are worth the extra money in the long term.

Also – TV’s use a hell of a lot of power so why not turn them off during an evening and go out and enjoy yourself – take your relatives out, experience the great outdoors! Sounds tacky I know but it works!

Install some solar panels – this will make your home energy efficient. Energy is created with these using natural resources. Solar panels can come in the form of solar thermal collectors that help the suns energy heat water. What a great way to use the suns natural power and to make your home energy efficient. Install a wind turbine or build your own wind farm in your back yard! Wind Mills can provide a lot of what is essentially- FREE- power from a renewable source that is the wind!

The best way to build your home totally energy efficient is to get off the grid by creating your own energy generating devices.

Сonstruct your own Wind Turbines, Solar Panels and convert your home to Green Power. Not only is it less expensive to build your own rather than pay money for them but it is also very rewarding!

Once you’ve created your own windmills and solar panels, your Energy Efficient Homes could be generating more energy than you can consume in which case you may begin selling your “Homemade Energy” back to the grid! The Energy Efficient Homes will offset the initial price of building wind turbines and solar panels and provide you some extra cash to spend on cooler things!

Yes!!! A DIY solar panel is able to reduce energy costs!!

I started making my first DIY solar panel to save my electricity bill when I saw that my electricity costs were soaring. In 2005 I spend $2,100 per year on my energy bill (slightly over the $1,900 that the regular family spends per year on their electric bill). In 2007 this grew to $2700. Sound familiar? This was getting out of hand. Therefore I asked myself how I could lower my electricity bill? I requested a solar installation business to give me an offer for an expertly installed solar system. I was astounded when they gave me a quote of larger than $26,000 for a basic solar installation on my house.

I didn’t have the funds for a professional contractor to do the installation and the payback time was way too long. Even if I would have been offered the federal support (of up to 50% for taking a PV panel in my house in the form of tax credits and refunds, reduced permit fees, or cash back systems, which depends on the state in which you live) it turned out to be still far too pricey for my salary. I started searching on the internet if there were alternatives or used panels to buy.

I saw info concerning a DIY solar panel and I even found some DIY manuals available to assist you through step-by-step instructions to build them. The manuals turned out to be extremely functional. I’m okay on the mechanical parts, however I feel less at ease with the electrical part of a homemade solar panel system. And this is where I truly benefited from the instructions in the manual. I purchased a guide and when I built my own home made solar panel, I was amazed by the results.

- It decreased my forever increasing electricity bill. Electricity business rates have been progressively rising by about 6.7% every year, and a 30% jump within the last three years solely. After having my homemade solar panel system, I saved almost 80% on my energy bill (on average during the year).

- Low system costs. It couldn’t have been a better deal. I managed to keep the costs for the materials at around $200 and paid $49 for the guide itself. I therefore had a payback of less than a year. This is a return on your investment better than any bond or stock that you can see in the market these days.

- Quality of instructions. The manual that I used was self explanatory. Fantastic images and videos made building a home solar panel a pretty easy task (and I’m not DIY savvy) and a great fun DIY project.

- Green solution: I’m contributing to the energy challenges our planet is facing.

After I noticed the positive influence that a DIY solar panel installation had on my electric bill, I was interested to know if there were other manuals out there that would be able to tell me what way to tune the efficiency of the installation even more (solar panels have a fairly low effectiveness in transferring the solar heat into electricity; the energy transfer of solar heat into hot water is more efficient). Thus nowadays I am the owner of my own homemade solar panel and I never regretted it!
