We are targeting to leverage our existing installation base by almost 50% to 4.5 GW (from existing level of 3 GW) in the span of next 2 years

  1. What are your views on Inverters – Make in India


As of now, we as country are definitely not self-sufficient to cater to our ambitious plans of capacity additions under National Solar Mission & other initiatives by central & state governments in the solar sphere, in terms of major equipment supplies including the Solar Inverters.

Major raw materials like semiconductors & few others, which are being extensively employed in Manufacturing of Inverters, are still being sourced from other countries in Asia, Europe or America. We do not have any indigenous supplier for these products even now. This is despite of Government’s aggressive approach to facilitate conducive environment for investments to develop a modern and efficient infrastructure under Make in India Drive. Hence, to have the cost viability of the Solar projects which are to be announced/implemented, it would still be highly imperative that these raw materials are allowed to be sourced from the respective country of origin with minimal imported duties & same may continue, till we develop sufficient manufacturing capacity in India.

On the other side, the step pertaining to increase in the Basic Custom Duties on finished goods i.e. the Complete Solar Inverter, is definitely a welcome move & well appreciated by indigenous manufacturers like us as it really makes them competitive against the heavy influx of the imported inverters.


  1. Kindly enlighten our readers on the performance of your Inverters in India in various geographic locations, customer feedback,


The solar inverter is a key and an important component of the photovoltaic (PV) systems that changes the direct power (DC) from the PV array to alternating power (AC) used in the electrical grid may be an autonomous or grid connected. It really affects the inclusive performance of the PV system. The solar inverter does not only convert the DC power into AC power but it also regulates the PV system so that the maximum power is being obtained from the whole system.

The Performance of our Solar Inverters has been well appreciated by our customers/users both in terms of product performance & Reliability. With 3 level IGBT technology, suitability to operate at higher ambient temperature and wider MPPT range, Hitachi Solar Inverters are delivering considerably high Output in terms of intended power generation & also consolidates immensely the reliability of plant operation. Hitachi Solar Inverters are among the most popular Grid Tied Solar Inverters currently in India also in terms of facilitating the major saving in the area of EBOP (Electrical Balance of Plant).

Hitachi Hi-Rel has been consistently maintaining uptime of around 99%  for all our Solar Inverter Installations. We also offer highly reliable after-sales-service-support from our dedicated & decentralized service centres located at strategic locations across the country.

With regards to the Geographical bifurcation of our installation base, we have 40% of our installation base in Southern part, 30% in Northern part, 20% in Western part & approx. 10% in Eastern Part of the country,

With respect to the customer feedback, there are plentiful positive responses and standpoints from the well-known and renowned power generating companies, Solar developers & EPCs of India for the Hitachi solar inverters supplied to them by Hitachi Hi-Rel. Few of the key feedbacks received are, Hitachi solar inverters are really running successfully and satisfactorily in all weather conditions, These inverters are user friendly, highly efficient & easy to maintain, many customer provided their accolades in terms of they being fully satisfied with the prompt service support from Hitachi service team & inverters meeting the guaranteed uptime as assured since commissioning,.
