SMA Solar ,the biggest German Solar Energy company is now losing marketshare to the new solar inverter manufacturers in USA and China. Note SMA Solar held a dominating 40% solar inverter global marketshare in 2010 compared to the solar panel manufacturers none of which has managed more than a 10% marketshare . SMA Solar however is now feeling the heat of the competition as solar energy prices continue to go down steadily. The pressure on the solar inverter companies has been increasing as solar inverter prices as a percentage of the total solar system cost has risen from 5% to almost 10% now as solar panel prices have come down much more rapidly.

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.

Solar Microinverters typciall sell for 75-90c/watt which means that if all the solar installations in the world at around 18 GW were done using microinverters,then the size of the addressable market would be $12.5-16 billion,however a lot of the installations are larger than 1 MW in which micro inverters are not used.Also micro inverters are mainly sold in the US and Canada so the total size of the addressable market becomes more like 500 MW which is around $$375-450 million dollars.Enphase Energy the biggest microinverter manufacturer has sold around 500,000 prouducts which implies total lifetime revenues of around $40 million.According to IMS Research around 1 GW of microinverters would be installed in 2013 and the market size would be around $700 million.I think the market size will be greater given that other geographies have not been penetrated,the residential solar market is growing faster and more companies will lead to a bigger market
