Total Project Opportunity in INDIA = 4500 talukas x 20 MW solar PV /taluka = 90,000 MW i.e 90 GW (refer my article in Energetica INDIA). But, India has plans to add only 20 GW till 2020, hence, this kind of shared business model with funding and secured business and financial models to offer low cost solutions through state government for the federal autonomy to create large number of jobs and also to increase Agriculture GDP, hence, this approach to team work to create large number of small entrepreneurs in their local taluka place.
Those who have access to Indian State government to realize on this new solar PV project development and also in Middle East, Africa, South East Asia.

Solar Inverters for grid connection and have been developed in order to minimize cost, better performance and extreme simplicity of construction, operation and maintenance. Applications: residential installations, industrial installations, big photovoltaic plants, isolated installations, etc. Multi-megawatt solutions customized to each project and string boxes to maximize the solar PV systems.
Gozuk photovoltaic inverters developed from its experienced designing and manufacturing industrial, robust, reliable, secure and high efficiency power electronics systems. The PV Inverter turns the DC mains coming from a solar PV field into a stabilized AC voltage power output. The central inverter works in grid connected mode, injecting the produced power.

100% failure is not an outlier in my experience. It may not be mechanical failure, but comms instead. I have seen very close to if not 100% of systems installed have some sort of issue, or multiple failure issues. No one really has the communications side of these things down yet. Communication, or inverter malfunction errors are typical on any micro installation I have seen. The costs of micro inverter versus central inverter replacement and micro service calls are much more expensive. I cannot imagine deploying micros on a commercial scale until a few things happen. The price per unit would have to fall dramatically in order to make up for the increased labor costs, and the communication issues would need to be orders of magnitude better.
We have installed a 140kw micro inverter system and it was at the customer request. The saving grace of the installation is that it is a carport structure and the micros are accessible via an 8' extension ladder. No modules have to be pulled in order to service a micro. I do not recommend micro inverters to anyone looking for more than a kw or so. That is also changing with newer small HF style central inverters with low MPPT ranges. That being said, the customer base Loves micro inverters. Many customers are sold on them before speaking to a sales rep, so someone on the micro side is doing something right! The shading argument is a little off in my opinion and there is a fine line between selling someone a system that has incremental shading, and selling someone a shady system..... System design with a micro can be more simple for a non technical sales person, but it can also lead to poor array placement if left unchecked by the technical support and engineering staff. There is a lot of, oh look a big roof with shade on it, lets use micros inverters happening out there right now. I am in agreement that they have a place in the pv world, but due diligence and robust system design should remain prime drivers on site selection.

When you hear about the suitability of a particular inverter technology for a particular project, it comes from the perspective of this hard-earned experience. To the best of my knowledge, no peer reviewed paper has demonstrated a performance advantage for micro inverters in commercial applications -- let alone an LCOE advantage (taking into account the considerable difference in price points for string or central inverters compared to micro inverters). Perhaps you can show me otherwise?
I have seen recent work presented by NREL which demonstrates the performance advantage of the micro-inverter architecture for shaded conditions. This analysis appears to be well done and we appreciate the rigorous approach. Again, though, I wonder if the performance advantage (3.7% in the case of light shading) can overcome the price premium for the microinverter system.
So we tend to think that other factors are at work in the inverter market. The perceived ease of use of micro inverters shouldn't be discounted, for example. In the fast-growing North American market there are many new entrants so this factor is important. We are excited to be launching our SB 240 micro inverter system this year and look forward to serving the needs of these new entrants to the market and those companies who have built their businesses around the characteristics of microinverter technology. We have a few tricks up our sleeves and are optimistic about our chances to compete in this segment. After all, our track record is pretty good.
However our firm opinion is that over time even these new entrants might seek ways to improve returns and move towards more established technologies with proven gains in LCOE or ROI.
BTW, this might also explain your comment about "integrators turning to micro inverters for large-scale projects." I wonder if you can point to (for example) any of the Top 15 commercial systems integrators who are using microinverter technology for large-scale projects? If one supposes that these large, sophisticated integrators might be using global best practices, then it might be important to note that these companies rely on central inverters or decentralized string inverter architectures to deliver leading returns to PV investors.
