Solar Roof top systems with NET meter are
becoming popular as many state Utility ESCOMS have started accepting excess
generated solar power from the consumer roof top & pay for this. MNRE is
providing 30% subsidy through state Nodel agencies & commercial
establishments are getting additional benefit of A.D of 80% in the first year
which is making solar power plants popular.
MNRE has already sanctioned installation of Roof top solar
power plants of 43.25 MW size to 11 states with subsidy amount of 129.58 cr
& already released amount of 1.26 cr to CREST & 2.41 cr to NREDCAP.
Solar Inverter is main part of solar power plant which is an electronic
equipment & need regular service support when ever Inverter becomes faulty.
MNRE took initiative to empanel the local Inverter
manufacturers & has already empanelled 27 companies. They have denied the
empanelment to many companies who were not having the local manufacturing
facility in India. But after this empanelment MNRE are not insisting the
State Nodel agencies to use the MNRE empanelled Inverters makes for their
Due to this state Nodel agencies TEDA (Tamil Nadu), NREDCAP
(A.P) have empanelled Chinese make Inverters for their projects. Even though
there are more than 15 manufacturers are manufacturing Grid Tied Inverters in
the MNRE empanelled list, Solar Installers in Tamil Nadu & A.P are importing
Inverters from China since TEDA & NREDCAP allowed to use cheap Inverters
As per the MNRE terms these Inverters should have 5 years
warranty & the life of the Inverters are more than 10 years. Both MNRE &
state nodel agencies are not bothered about the availability service facility
locally and these Inverters are imported & sold by very small traders &
in case of any fault in the Inverters there will be no service support.
Finally the end consumer who is not aware of this issue will
be the sufferer & the local manufacturers who are MSME units will not have
any business due to unhealthy competition from China supplies. These solar
Inverters should comply the safety standards like Anti Islanding (IEC 62116),
Safety of Inverters (IEC 62109), Utility Interface (IEC 61727) , but many of the
installations happening in A.P where Inverters do not comply to these standards.
This is very dangerous to maintenance persons of Escoms there
is a possibility of getting shock if the Inverters do not have Anti Islanding
test certificate, Consumers can get shock from the Inverters if Inverter do not
have Safety test certificate and finally consumers equipment can get damaged if
the Inverter do not have Utility Interface test report which also is a
requirement as per CEA guidelines.
When Central Govt is backing MADE IN INDIA why MNRE is
not insisting local Manufactured Inverters even after empanelling them &
provide subsidy to use of Chinese products.
Also they should insist for all safety certifications for
Inverters to safe guard the end consumers, utility maintenance peoples. BESCOM
(Karnataka) has already came out with Net meter policy & they are the only
state insisting for MNRE approved Inverters & also all safety
certifications. Many other states like Punjab, Uttarakhand, Kerala, Rajasthan,
Delhi are in process of calling tenders for solar roof top with Net meter &
they may go with Chinese Inverters & ignore all safety regulations if MNRE
doesn’t advice them.
My humble request to the honourable Prime Minister Shri
Narendra Modi Ji and Power Minster Shri Piyush Goyal Ji is to make sure that “MADE
IN INDIA” theme given by our Flamboyant Prime Minister is not diluted.
Do you know Sir, we had a huge number of companies which
were producing UPS (Un-interrupted Power Supply Systems) over 30000 families
were dependent on them, to most of these companies have churned there employees,
there is there is hardly an engineer to attend to so called, down time has
increased barring a few companies to more the 24 hours. In Engineering Colleges—Specialization
in Power Electronics is last sort after subject. As Chinese product takes over
in MSME business, we are mere traders. Those companies which fed over 30000
families are now struggling even to feed 20000 families. They have resorted to
change in product line - most of them started manufacturing inverters. I Ask you
Why Mr. Prime Minister. Your big Power Push is really good but please take care
of Middle Class India. The Aam Adami. If Chinese are so cheap let them
put their factories in India and compete with our fellow Indians. I am sure even
with better technology at their disposal they will get a tough fight from our
I write this, with deep pain in my heart as you had promised
End to Corruption, but you bring laws these Indian Agencies will have the
gumption to disobey you or find way. Indian Manufacturer will betrayed not by
the Nodel Agency, but your face value which made you what you are today will go down
drastically. I was trying to tell the truth, Sorry if I hurt your sentiment. Do
update me if I am wrong.
