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.

Solar Inverter Efficiency is increasing every year with increasing scale of operations,greater competition and rising R&D dollars being poured into solar inverter development.PV inverter Efficiency is vital to decrease the costs of solar power which is currently more than that of fossil fuels.While the cost of solar panels has come down drastically by almost 75% in the last 3 years,solar inverter costs have gone down by only 10% every year at most.The reason is that competition is lower in the PV inverter market because of the higher entry barriers of technology.While Western solar inverter manufacturers routinely get above 95% efficiency,the Asian low cost players have not been able to cross the technology hurdle of high efficiency.Note the Power Electronics in a solar system can make a huge difference to the power yields with even a 1% change resulting in thousands of dollars in difference in large scale solar farms.This is the reason that high efficiency solar inverters from the West command a big price premium over the less reliable lower quality PV inverters.You should be careful of any lesser known inverter brand they are offered as part of a home solar power system before installing them. While some of these inverters may have certification this does not mean they can perform as well as the good brands.Skimping of a few dollars here and there may make you penny wise and pound foolish.

After Solar Panels,Solar Inverters are the second most crucial component of the overall solar system accounting for around 10% of the overall costs.Solar inverters connect the solar panels to the grid converting the DC to AC which is used by the grid.Note for off grid solar installations,solar inverters are required as most electrical devices need AC for their operation.There are both grid tied and non grid tied inverters available on the market.Solar inverters have become highly sophisticated with features like optimization and monitoring etc.The efficiency of solar inverters are a major factor in their purchase as well as the quality and reliability.Inverters comes in various sizes and can be as large as 1 MW for utility applications.Note unlike solar panels,solar inverter manufactures are much bigger in size with SMA Solar having a 40% global marketshare.

Solar Energy is the fastest growing industry in the USA and has been one of the fastest globally as well with solar demand rising by more than 150% in 2010 fueled by massive cuts in prices of solar panels especially those from China.While this has led to a major drop in solar energy stock prices this has also led to a massive boost in volumes due to demand elasticity.Only the top solar companies will be able to survive this brutal consolidation that is taking place with some companies like Solyndra already consigned to the death list.Solar Industry is a global one and has a big supply chain as well.This means that looking at only one stock market will deprive you of better opportunities that might exist in other stock markets.There is also a big supply chain associated especially with crystalline solar panels.There are companies that exist only in Polysilicon,Wafers,Cells,Modules.There are also companies that are suppliers of material like encapsulants and metal alloys to these industries.This article will give you a very broad idea on the complete list of solar energy stocks that exist in each part of the supply and different parts of the world.You can also look at the 2 solar ETFs that trade on the US stock markets TAN and KWT .

Solar Power in India is set to be one of the biggest energy industries in the 21st century due to a unique set of favorable converging factors with declining cost the biggest one.The Indian government has recognized this fact and set a 20 GW of solar energy capacity target by 2022 and Indian states are boosting solar energy too through their own set of subsidies and solar supportive policies as well.However a number of problems have cropped up in the initial phases as solar electricity price is still high at Rs 14-16 unit compared to the retail electricity price of around Rs 4-5/unit.Though solar subsidies by the government should provide support till the prices come down.Major Indian solar companies like Moser Baer,Lanco are predicting that the solar electricity costs will fall by 40% or more in the next 3-5 years as technology improves,scale increases and more of the components like glass,solar inverters are manufactured domestically substituting expensive imports from countries like China and Taiwan.

Ontario Canada has a comprehensive solar subsidy policy which mandate that a large percentage of solar components be manufactured in Ontario in order to receive the Feed in Tariffs.This has led to a mini manufacturing boom in the province with a number of companies like Conergy,MEMC,Enphase,Canadian Solar putting up factories to take advantage of the FIT.Japan which is also a large manufacturer of solar panels with major Japanese solar companies like Sharp,Kyocera has taken Canada to the WTO citing improper competitive practises.India which has one of the largest potential in solar energy installation too has promulgated a law that requires domestic content requirements.Solar Modules must be produced in India to gain FIT under the JNNSM.This law is expected to become stricter with solar cells also to be produced in the country in the future.This has drawn howls of protest from American officials who too tried domestic content in their subsidies under the Stimulus Act.
