BP: The Indian solar energy segment is considered to be a market with one of the fastest growth potentials in the world due the country’s ever-increasing demand for energy. India is one of the countries with the largest production of energy from renewable sources & in a now days Wind power is now the world’s fastest growing energy source also. India has abundant availability of solar irradiance and receives solar energy throughout the year & this has created enormous opportunities to solar energy from the sunniest sites in the country, especially from Rajasthan, Gujarat and Andhra Pradesh. India is situated at an ideal geographical location and receives ample tropical sunlight.

There are almost 300 sunny days with clear skies each year in India. Thus, rooftop solar panels are ideal to be used here. Along with the
generation of electricity, solar power can meet several other purposes.

According to a new study, the market for Solar Hybrid Inverter is witnessing a noticeable surge across the world. The research report, titled “Global Solar Hybrid Inverter Market 2019 Industry Research Report,” explores the past and current appearance of this market in a bid
to earn a clear insight into its future potentials. It also takes the driving forces, challenges, prominent trends, opportunities, and various
other factors that influence the growth of this market in consideration to discover the market’s scope in the years to come. SOFARSOLAR is
currently focused on increasing its core technology R & D investment in Grid connected inverters, Energy storage inverters and it’s charging
pile. With this in mind, they aim to improve the competitive advantages of their core product range and provide further valuable service
to their customer base.

SOFARSOLAR HYD inverter can work in auto or Time Of Use (TOU) mode, charge / discharge the battery when needed. In auto mode, the HYD-ES inverter will charge surplus PV energy into the battery & discharge battery to supply power to local load when PV energy is not enough. In case of blackout, HYD ES inverter can work in Emergency Power Supply (EPS) mode. HYD ES inverter will utilize power from PV panels & energy stored in the battery to supply power to critical load. With many new functions, SOFARSOLAR battery inverter were widely
used in 60+ countries (e.g. Australia, the UK, Germany, Italy, Belgium, Spain, Netherland, France, China etc.), which enable residents’ supply to be secured even in the event of grid failure and decrease the electricity bill. While you have this storage power station and HYD inverter, you may have non-stop energy 24hours.

ZED ( Zero Export Device) :
In some part of India it takes several months to get NET METERING done for their On-Grid Solar Power Plant. It will leads to a huge loss of power production due to delay in net metering. With Zero Export device you can run your PV plant without net metering.

A solution to these problems is Zero Export device will enable solar system owners & operators to limit the amount of solar power that their systems export to the GRID. The integrated power analyzer measures the total power at the point of coupling and compares this
with the adjustable set point of the controller. When the consumption from GRID is above this set point, the solar energy will be increased,
when the consumption is below this set point, the solar energy will be reduced.

EQ: What according to you is the current opportunities, biggest challenges, in Indian Solar Market.

BP: In a now days demanding hybrid inverter, ZERO EXPORT Facilities for net metering &,roof top projects in largest MW Scale with
government subsidies facilities , Agricultural solar pumping project with beneficial scheme for farmers & storage inverter future will also
come very soon. Upgraded technology From 1000V/1100Vdc system to 1500Vdc system in string inverter for to option availabilities / switching in central inverter to string inverter for coast effective & easy service solution. . Already SOFARSOLAR Hybrid & Storage inverter performing very good in EUROPE,NETHERLAND,POLAND & AUSTRALIA market. In India North East & South India very good market for hybrid inverter business.

EQ: Aggressive Bidding despite of many challenges enlisted above, what is your view/opinion.

BP: In India solar market is growing vey well but in a now days solar energy has suffered with some weakness points related to cancellation of allotted project bidding. Solar industry is just come out from the safeguard duty but market movement now going slow due to cancellation of big auction. Recently nearby 4GW auction cancelled by many agencies (SECI,GUVNL,UPENDA,Etc..). after auction opening if it will be completed within shorter time with policies & decided tariff then market will take some faster movement of project completion.

EQ: What are your plans for Manufacturing set up in India, the opportunities and challenges in manufacturing in India ?

BP: Well, very interesting question about local manufacturer. If local manufacturer follow process as per required testing facility , production facilities & required manpower to do complete manufacturing task with proper testing/quality process then customer will get proper worth products as per invested coast. We are recommending to client don’t go on cheap prices & polycarbonate type of body with lesser durability life product available in market. In a now days if any local company providing cheap price product without complete process & assemble type of products so it will be not a long life system. So if client not aware about process so we requesting to them go with proper process & visit some manufacturing company in abroad or collect some online data or visit some online manufacturing setup videos & gain your knowledge to get proper product without any cheating in systems.
