3 Phase Solar Inverters are another name for Grid Tied Solar Inverters which allow the DC Power generated by Solar Panels to be connected through the Grid.Note most of the Solar Inverters manufactured earlier used to be off grid solar inverters and did not have any grid connections.However the Feed in Tariff Laws in Germany and other European countries has made 3 phase solar inverters a massive growth industry.All major solar inverter manufacturers make 3 phase solar inverters in a wide variety of power ratings and voltages.The difference between a 3 Phase Solar Inverter and a normal Solar Inverter is that the Three Phase Solar Inverter has to match the frequency and voltage of the Grid before it supplies power.Normal Solar Inverters on the other hand are not restrained by the voltage and frequency of the power grid.The grid tie inverter must synchronize its frequency with that of the grid (e.g. 50 or 60 Hz) using a local oscillator and limit the voltage to no higher than the grid voltage.

New Solar Panels and New Scientific Breakthroughs in Solar Technology it seems are reported every month.But Solar Energy is still not competitive with Fossil Fuel Energy despite its obvious advantages.The costs of Solar Energy are declining quickly but they remain still some way from being on par with the dirty forms of energy like Coal.The reason for all these new exciting technologies which are reported in newspaper not being able to bring a fundamental change in the energy scenario is that the costs are too high.Bringing a new solar panel technology from the lab to the factory takes a lot of time and effort.During this time the incumbent technology like crystalline solar technology keeps advancing due to the massive global R&D dollars that are spend and the rising scale.This had made many new startups in solar technology like Solyndra ,Spectrawatt and others bite the dust.You can read about the large number of solar failures in the first wave of thin film solar bankruptcies .

A solar array can be defined as solar panels arranged in a group to capture maximum amount of sun light to convert it into usable electricity. The idea of Solar Array came into being when it was conceived that the power produced by a solar panels singly was not sufficient for domestic or commercial purpose. Many such solar modules are linked together to form a Solar Array. Solar panels can be arranged differently to form different patterns to suit ones purpose. Depending upon what the need is, different structures can be build. Generally there are two traditional styles of solar energy panels used in residential and industrial areas -photovoltaic and photothermal energy. Most solar arrays to date have been a mixture of these two. Because it is relatively low-tech, solar arrays are a very cost effective approach for people who believe in DIY technology.

Auto Industry in India is facing the twin problems of Fuel Price Hikes and High Interest Rates which have sharply reduced the growth of the industry.The Indian car companies were riding high in 2010 as the economy grew and many people in India graduated to the middle class.Some companies were showing triple digit growth rate as India become the hottest market in the world.All global car companies were in a rush to expand their India sales and distribution network at any cost.However 2011 has brought them down to earth with almost 50% increase in petrol prices keeping buyers away.On top of that car financing companies have also increased their interest rates for auto loans by around 2-3% which makes the servicing of the EMIs of car loan very difficult.This has made most buyers sit tight and wait for a better environment.The car companies which hiked price to pass on the increasing costs of steel and other commodities are in a pickle.They are being forced to sit on high inventories and can’t afford to give big discounts as well.

The sautomobile industry in India happens to be the ninth largest in the world. It is the fourth largest exporter of automobiles following Japan, South Korea and Thailand. It is the world’s second largest manufacturer of motorcycles, with annual sales exceeding 8.5 million in 2009. Several Indian automobile manufacturers have spread their operations globally. India manufactures over 17.5 million vehicles (including 2 wheeler and 4 wheeler) and exports about 2.33 million every year. India’s passenger car and commercial vehicle manufacturing industry is the seventh largest in the world, with an annual production of more than 3.7 million units in 2010. In the commercial vehicle segment, Tata Motors is leader with a market share of about 64%, whereas Maruti Suzuki is leads the passenger vehicle segment with a market share of 46%. Hyundai Motor India and Mahindra and Mahindra are more interested in expanding their hold in the overseas market. (Source – Wikipedia).

Greece Referendum is set to become the hottest media topic related to the European Debt Crisis in the coming months.In a totally surprising move Greek Prime Minister George Papandreou called a referendum and a parliamentary confidence vote on 31st October just a week after the European leaders had agreed on a package to .Papandreou’s personal and government popularity have plunged amid fresh austerity measures that sparked a wave of social unrest.The PM is calling this vote probably to bolster his government as it loses support of the masses

Solar Shingles are niche solar products meant for use on roofs of houses.There are not a lot of manufacturers of solar shingles as they are a new product and more difficult to install than standard silicon solar panels.Solar Shingles are manufactured by mainly American companies like Dow,Energy Conversion Devices.Their high costs and lack of easy availability has meant that solar shingles have not really caught the imagination of the customers.Also Solar Shingles do not get any added subsidy from the government vis a vis Solar Panels.Thus the higher prices of electricity generated from solar shingles means that they have become a poorer cousin of the mainstream Solar Panels.Also Solar Integrators are more accustomed to buying and installing solar panels which makes it even more difficult to push the sale of solar shingles.
