4) What have been the latest technology trends in solar inverter market globally & in India?
The year 2017 has been great for global solar PV industry in terms of installations. India’s soaring solar market has still very much up for grabs during the current and the coming years. We believe a slight contraction is on the cards for 2018, the opportunities for inverter suppliers to ship in big numbers remain vast. The grid support function like LVRT has made its way from a requirement to a compliance along with SVG functionality.
The modular design is making central solutions attractive along with its outdoor rating which eliminates the need of control room structure. Considering the increase in environmental ambient temperatures, the customers has high expectations in grabbing the inverters which will deliver the rated output power even at ambient temperatures of 55oC.
In 2018 we expect that 50% of all central solutions shipped to be 1,500 V and 1500VDC is here to stay.
Keeping its commitment on delivering innovative products, Delta has up with 1500VDC string as well as central inverters.
5) A brief on your growth in the past year and some milestones you wish to achieve this year.
Being India’s No.1 in the Rooftop Segment with 37% of the market share, we captured in major airports, key metro and railway stations, Government offices, public sectors and many more, with over 1000+MW of string and central grid-tied solar inverters already installed in India.
We are also happy to share that we have quite a few installations for both Rooftop and Ground Mount installations beyond 7 years in India, which have already completed the warranty period but we continue to render necessary support to our customers as and when required.
