How to Build a Homemade Solar Water Heater

In a world where fossil fuels are running low and where electricity becomes expensive with each passing day, people have to adapt and start living independent of these resources.

Considering all alternative energy sources available today, people should start implementing them in their lives, in their homes.

This is the reason why I chose to show you in this post the simplest way to build a solar water heater for your home.

Assembling this system is not very difficult but it is important to take into account several things:

Before you start installing this solar heating panel, you have to decide where it will work best. It should be installed where it can find maximum sunlight. It is also better if you’ll keep it close to the back up heater.

For maximum efficiency and zero risks you have to use water tight panels sealed with plexi-glass. To make it water proof it should be endorsed with black pond liner.

Today, panels are made of thin cylinders because of their greater efficiency. Plywood tank is a substitute for the thin cylinder, which is a shallow box with the plywood bottom and four walls used for the water tank.

At the bottom of the panel you have to connect the pipes using connectors. The role of these pipes is to drive water from the house to your solar heater. With another set of pipes connected at the top of this heater you’ll send the warm water back to the house.

The color you’ll use to paint your solar heater will be black (including the inner side of the panel). Black color absorbs light rays better than any other color and it stores heat energy efficiently. You have to make sure that the paint dries completely.

Now when you’re almost done, you have to cover your panels with a part of plexi-glass acrylic plastic.

For the purpose of glazing glass is the most appropriate material (for homemade water heaters). To avoid leaks, glazing should be done carefully and also make sure to glue the panes perfectly to avoid condensation.

This homemade solar water heater should not be very difficult to build. Give these plans a try and start build it. Good luck!

China surprises with a huge building powered by the sun

The construction of the image shows the development of China's true power - the "Sun Dial", the largest business center in the world with solar power.

Roof with solar panels has an area of 75,000 square meters, and below it are huge spaces for exhibitions, research laboratories, conference and training rooms, offices and even a hotel.

In making the imposing steel structures used very little, only 1% of the amount used for raising the famous stadium "Bird's Nest" (Bird's Nest), who hosted the 2008 Summer Olympics.

To save as much energy, the walls were isolated using cutting-edge technologies. The official inauguration of the building, located in Dezhou city, event happened during the 4th World Solar City Congress in the autumn.

The primacy of this achievement but it might take less, because the Arabs are ready to close in February 2010 an entire solar city - Masdar City. Their plans may still be foiled by the economic crisis, felt even in the emirate of luxury and extravagant - Abhu Dhabi.

Solar panels on roofs, parking lots

Several French players and / or European energy looking for parking uncovered implant devices to support solar panels for electricity production. Alter-negotiation company was mandated by these operators to negotiate with owners of parking was to be interlecutor and make technical and administrative feasibility studies. The parking area must have a minimum of 90 parking spaces and a south exposure.

Parking for each owner advantage of the operation are not insignificant:

- Improve parking by installing a structure (whose investment is made by the operator) that protects users and vehicles against adverse weather conditions and sun rays;

- Sun protection vehicle generates a minimal use of air conditioning, responsible mostly for the production of carbon dioxide, and reduce fuel consumption;

- Promoting your image as Secretary of the Environment;

- Providing a down payment for rent. Furthermore, a photovoltaic installation is not any risk in terms of safety goods and people, the noise or smell, the issue of toxic pollution into the atmosphere or groundwater blades. Facilities made are reversible (can always be removed). As the owner does not take care of nothing more than to provide parking and to sign a concession contract for 20 years. No fee (feasibility study, impact) do not enter your obligations or the beginning of operation or during operation of the plant.

Installation of photovoltaic electricity production last generation

The department Green Power, ELECTRO - VOX has put into operation at the plant in Ploiesti (Roumania) a photovoltaic electricity production last generation.
Installation of 2 025 (w), is composed of high quality components produced by companies SunPower SMA USA and Germany, making exceptional electrical parameters: yield 18.5% and solar power panels 200w/mp * for power, and over 95% of the inverter coupling network.

Unit is dedicated to demonstrations and has already been put into operation on September 20, with modern monitoring capabilities through the Internet and has automatic guidance system for maximum efficiency zone.

Solar Panel Built at Home With Only $ 100 Using Mini Solar Panels From Old Pocket Computers

I was thinking today at those pocket computers that we all have in our homes or at the work place.They,as you have seen,have a small space like a mirror, which captures light from the sun and then the computer works without batteries. I thought the next thing:I want to get that photovoltaic part from it and connect with much more same mini solar panels, together and form a panel of 1 square meter,similar to usual solar panel.



I'm curious how energy will provide that solar panel.Do you realize that such a panel will not require so much money .. I mean about $ 100(the cost of pocket computers wich i will buy), may even less.Anyway, compared to those expensive solar panels expensive (over $ 10,000) this is an insignificant amount of money.I will do the experiment and in one of the following posts i will present it.But, before I want some opinions or suggestions with how I should proceed ... if it is possible to build this "home made solar panel" or not.

Air Conditioner Device that Uses Solar Energy

Were recently presented several projects related to an air conditioner more efficient and environmentally friendly than those usual found in people homes.Nowadays this project was launched on the new air conditioning system market.This system does not require a large amount of water to adjust the air temperature and composition in our homes and also uses solar panels to work.Is named Chromas.
This system uses photovoltaic and termal cells that retain solar energy for heating process.Usual solar cells used in most of our homes retain only 24% light transmitted by the sun to those cells that reach up to 76% solar energy storage capacity.Heating water is also much easier because solar panels that are attached and also because some tubes of oil heated by the sun at a temperature of 230 Celsius degrees.
Those special solar panels uses 90 percent less energy for heating water or to adjust the air in the room after your wish.Now, this solar air conditioning wich work on solar panels is only a prototype but at the beginning of next year will be accessible to all who will need it.

Solar Powered Shaver with Mini Solar Panels.7 Hours for Loading Batteries

This device it looks like a normal electric shaver.The only one difference between this gadget and the regular one is that cause this shaver conected with a mini solar panel.Now,this solar panel could be a regular solar panel based on silicon or an flexible solar panel.Flexible solar panel is more usefull in this case because the device will have a rounded design.
This mini solar panels are uploading a small battery in approximately 7-13 hours.This gadget,when is not used ,should be left in a place where sun light.If light is more intense the device will load faster.
The isadvantage of those flexible solar panels is that they have no enough power to capture the sun light as those built on silicon.However the device is a good invention like any other solar inventions that make some energy savings in every man's house.

Plastic Solar Cells.Solar Cells Cheaper Chan Ever

Researchers have discovered a new type of solar cell which is more easily manufactured and requires a cheaper material than the silicon used by now.Those cheaper solar cells are manufactured on the basis of polymers, organic substances, which, leads to a much lower price than those from silicon created from unorganic semiconductors.It is something natural that what is received from nature to be cheaper than something produced by humans through various technologic processes.The polymers types used for creating such cells are of three kinds: one with electron-deficient,one organobor, and a polymer containing a large amount of electrons.The last two types of polymers that we have presented are actually:carbon, hydrogen,sulfur and boron.This type of particles are able to retain the light from about 450 nanometer (violet) and 800 nanometer (red light). What is amazing is that one such cell is formed of a thousand trillion such particles all placed on a surface of 1 inch square.This solar panels will have many more ways to use because they are flexible.Plastic solar cell greatest advantage in these times of financial crisis is that solar panels are much cheaper.

100% Natural.Organic Solar Panels

Most solar panels are built with silicon cells, but a new discovery indicates that solar panels can be created and based on organic substances.(organic bands).Those panels that are using silicon cells are more efficient than organic solar panels.The advantage of this type of solar cells is that they are flexible and can be used in other new areas such as application on small electronic devices.Already this project was implemented, as you know there are,for example,mobile phones that use small solar panels to work(Samsung Blue Earth). Another advantage of organic solar panels is that they are cheaper than any other solar panel.In fact these bands are created from organic substance from plants that have the ability to retain solar energy.I think that a gadget that uses these organic solar panels is "100% natural "because it receives energy from nature (the sun) and the system wich retains all the energy is based on organic substances, so all natural...

The Largest Solar Central Will be Built in Northern China

The largest Solar Central is in Portugal "Amper Central Solar", but Chinese announces that they will build a largest central than "Amper Central Solar" in the North side of China.
This project belong to China Technology Development Group Corp and Qinghai New Energy Group. With 150 million China Technology Development wants to build this center that will initially produce 30 megawats.
It seems that the company is quite serious and after he made that announcement "before the end of the year wants to build the solar central", actions have increased by 30%.The maximum power that the central could produce will be up to 1 gigawat.
