Homemade solar panel can either be used for converting solar energy to heat or can be used for producing electricity and the later option is better for us. The later form of homemade solar panel also known as photovoltaic panel and these panels convert solar energy into electricity. The electricity produced by the panel is directed to a battery and we can withdraw electricity from the battery as and when electricity is required by us. We need to install these panels to our roof so that these absorb the highest amount of solar energy and which ultimately get converted to electricity.

These homemade solar panels are best for everyone and it is the best time to curtail huge electricity bills by producing our own electricity from readily available non-conventional sources of energy. You can get a readymade solar panel from market or you can make your own solar panel. You will typically require solar cells, tabbing, copper, soldering iron etc. Even if you have no professional experience, you can make your own homemade solar panel. You can take the help of readily available guides and you will get the exact information including complete list of tasks required for making the panel.

Although an initial investment of only $200 is required for assembling the homemade solar panel and once you get the panel assembled, you just need to install it at your roof or at your backyard and you will start getting electricity and you can save huge 70 percent of your electricity bills every month. If your electricity consumption is low or your area gets high amount of solar energy, you can even make excess electricity and can sell the electricity to the electricity supplying companies.

Electric and gas hot water systems accounting for approximately 20% of a household’s greenhouse gas emissions,and by installing a solar water system you will reduce these emissions and also save up to 75% of your water heating costs! Table below is sourced from the Debartment of Environment and Climate Change NSW.

Solar pool heating uses a similar technology to building / household solar hot water systems. Solar pool heating involves covering a roof with a black blanket of coils and pipes which also get heated by the sun combined with a slow flow pump which circulates the water through the panel and into the pool. Unfortunately Energy Matters only installs building / household solar water heating systems and does not perform installation of pool water heating systems.

 

Flat plate collectors work on copper pipes running through a glass covered collector, often connected to a water storage tank on the roof. The hot water can then thermo-syphon itself in and out of the tank, thus heating the water. The updated option of flat plate collectors are evacuated tubes.

Evacuated tubes use a glass tube with a vacuum inside it and copper pipes running through the centre. The copper pipes are all connected to a common manifold which is then connected to a slow flow circulation pump which pumps water to a storage tank below, thus heating the hot water during the day. The hot water can be used at night or the next day due to the insulation of the tank.

The evacuation tube system is superior as they can extract the heat out of the air on a humid day and don’t need direct sunlight. Due to the vacuum inside the glass tube, the total efficiency in all areas is higher.

National Semiconductor (NI) -Headquartered in Santa Clara, California, USA, National Semiconductor is a significantly large semiconductor manufacturer, specializing in analog …, announced into the solar cell business, and the successful development of the solar system as a whole to increase the output power of technology “SolarMagic” .

The use of technology, even in the multi-block solar panels tied for the dirt or cubicle dislocation also be able to achieve the solar panels to maximize the efficiency of power generation.

California Solar System REgrid Power companies have started using the Solar Magic system’s trial. It has been said REgrid Power, and Solar Magic did not use the system, cloudy day the power generation efficiency can be raised by 44%, the overall increase of 12%.

There are other companies scheduled to install the solar (battery) cell will be a few months after the trial began this solar system.

NI in the United States intends to solar cells outside the country’s high rate of expansion of the system. During the year 2008 and plans to achieve the SolarMagic product commercialization.

A solar cell or photovoltaic cell is a wide area electronic [1]device that converts solar energy into electricity by the photovoltaic effect. Photovoltaics is the field of technology and research related to the application of solar cells as solar energy. Sometimes the term solar cell is reserved for devices intended specifically to capture energy from sunlight, while the term photovoltaic cell is used when the source is unspecified. Assemblies of cells are used to make solar modules, or photovoltaic arrays.

Solar cells have many applications. Cells are used for powering small devices such as electronic calculators. Photovoltaic arrays generate a form of renewable electricity, particularly useful in situations where electrical power from the grid is unavailable such as in remote area power systems, Earth-orbiting satellites and space probes, remote radiotelephones and water pumping applications. Photovoltaic electricity is also increasingly deployed in grid-tied electrical systems. Similar devices intended to capture energy from other sources include thermophotovoltaic cells, betavoltaics cells, and optoelectric nuclear batteries.

Solar Electric

The preferred term used to describe something which uses sunlight to produce electricity. “Photovoltaic” is the more technical term.

Solar Cell The smallest basic solar electric device which generates electricity when exposed to light.

The Energy Matters Solar-Port is the ideal portable power source for use in the Great Outdoors. Be it for camping, exploring, boating – anywhere you need to have instant power on the go. The Solar-Port converts in a matter of seconds from a sturdy suitcase to a self supporting solar power unit – ready to power

life’s necessities!

The Energy Matters Solar-Port includes two 50W solar modules in parallel with peak power voltage of 17 volts and total peak current of 6 Amps. This voltage and current are suitable for general battery charging.

It is recommended to use the Solar-Port with a solar regulator (charge controller) between the Solar-Port and the batteries. A solar regulator will continuously check the battery terminal voltage and allow the battery to be charged only if it requires charging. It automatically disconnects the battery from the

Solar-Port when the battery is fully charged. Solar Energy Matters recommends using the Morningstar 10A 12V Sunsaver regulator when charging batteries from the Solar-Port. For additional information on Energy Maters Solar- Port please got to www.energymatters.com.au, or contact our sales department on sales@energymatters.com.au or 1300 727 151.
