in the market in terms of financing is that, for any kind of solar projects Indian banks provide finance at high interest rates. The high cost of financing is a huge deterrent to the solar projects. While calculating the ROI with these high interest rate the projects become very unviable mostly. On the other hand the foreign banks are financing the same projects at much lower interest rates making the projects viable. Thus a large number of the solar projects in India end up financed by foreign companies on their own terms and conditions. Due to which foreign companies are making Indian developers use products from their own countries.

5. Please enlighten us on the projects executed and in pipeline worldwide, and India. Ans. Presently we have executed the following orders in India •

2MWp solar power plant in Chandrapur, Maharashtra under MAHAGENCO

800kwp solar power plant in Narnaul (Haryana)

2Mwp Solar power plant in roorkee

DC works for 4.5Mwp solar power plant in Pokhran (Rajasthan)

Several 2KW to 100KW roof top projects country wide

Projects in pipe line are as follows (in India)

25 MWp solar power plant coming up in Maharashtra by MAHAGENCO

3Mwp solar power plant in Rajasthan by a local developer

Projects under REC scheme at various places in India

Off – Grid projects for rural development in India

Water Pumping projects in India

Ans. Sorry!!!! But we never got a chance for experiencing the work culture in solar farms in European countries, hence we cannot comment on it. Well looking at the prevailing market scenarios in India and Europe. There are certainly some differences which can be noticed.

Projects executed are as follows (International)

More than 500 roof top systems delivered in the state of Maryland, Virginia and Washington DC, USA

Several rooftops delivered in New Jersey, USA

For E.g. we feel that the European market is more stable as it is not cost driven instead it is more technology driven market. On the other hand Indian market is cost driven due to which it is very unstable. The cost of putting up a solar power plant has reduced from 16.5 Corers to some 8.0 Crores in last one and half year.

800KW system delivered in Sardinia, Italy

There are huge differences in the solar market of India and Europe. But still there are a few things we can take from the European markets. Such as, we have to give more importance to the quality of the product than the cost, as these products have to run for 25 long years.

EQ : What are the experiences and learning’s from Europe for constructing a solar farm. How do you think India is a different market than Germany and rest of Europe? What are experiences in India?

We have executed several projects in India and all of them in very different conditions. Due to which we can say that we have a fairly good idea of the execution and things required for execution in Indian conditions. One of the major issues is that we don’t have skilled labors in India hence execution becomes very difficult. Our engineers have to train the labor and show them how different activities are done in different parts of the plant. On the other hand the lack of infrastructure available on

EQ : Please enlighten us on the experience of working with different technologies (c-si vs. Thin Film, Fixed vs. Tracking, String vs. Central Inverter etc…) what’s the ideal solution for India and why. Ans. We have worked with both the technologies i.e. C-SI and multi crystalline. Multi crystalline technology is well established and well proven as compared to thin film. Thus for an investment which is based on long term cash flow it is important to keep this in mind. We manufacture multi crystalline and can definitely confidently talk about the robustness. With higher

efficiency of the modules a similar system size would occupy one third the space with multi crystalline over thin film. While working with Multi crystalline modules we feel that it is very easy to work with these modules as they are robust and are easy to work. There is less risk involved in activities like module loading, unloading and shifting. It is seen that the breakage of modules is also far less with multi crystalline as compared to thin film. In a way we can say that execution becomes really easy with Multi – crystalline modules. Thin – film modules are no doubt a bit lighter in weight than Multi – crystalline modules, but they are also very fragile compared to Multi – crystalline modules. We have seen huge breakages in modules during loading, unloading and shifting of modules. Since many of these modules are frameless, hence installation of such modules is also difficult. Overall we can say that compared to multi – crystalline execution of solar power plant is more difficult and tedious work. In the case of structures we feel it is much simpler to carry out installations on fixed structures. As the design of these structures are pretty simple and hence makes it easy for the unskilled labors to carry out installation of modules. On the other hand tracking systems have some of the problems. Like the design is too complicated and takes time for installations. We cannot disagree the fact that with the use of trackers we can increase the generation. But then we should be ready to face the challenges while executing the plant with trackers. Generally we have used central inverters for all the Mega watt size power plants. In which we have to build inverter rooms for every one mega watt plant. With the use central inverters for power plants we increase the cabling a lot. In case of central inverters DC cables are more used than the AC cables which lead to increased losses in power plant. String inverters are generally used for KW size rooftop installations. Some of the advantages in using string inverters are that with the use of string inverters we can remove the use of DC cables and junction boxes. Due to absence of DC cables and junction boxes the losses in the plant are reduced drastically. The maintenance of the plant becomes easier. EQ INTERNATIONAL July/August 12
