Is this due to your solar power credit from the grid? Are you supplying to the grid?

In another news, there appears to be some evolving situation of India pioneering a global strategy [one sun, one world, one grid] in creation of regional and international interconnected green grids.

“One Sun One World One Grid" (OSOWOG) plan - an ambitious global electricity grid

one of the most ambitious schemes undertaken by any country and is of global significance in terms of sharing economic benefits

Creation of regional and international interconnected green grids can enable sharing of renewable energy across international borders and also balancing. Such grids should work in tandem with the existing grids and will not require parallel grid infrastructure, thus requiring only incremental investment.

The global grid plan may also leverage the International Solar Alliance (ISA) co-founded by India that has 67 countries as members. It has become India’s calling card on climate change and is increasingly being viewed as a foreign policy tool

The savings is large because for electricity consumption of 500 Units and above, we have to pay ₹7.5 per unit.

Cumulative solar export stands at 12709 units, this excludes the solar power consumed by us during the day.

12709*7.5 = 95317.5 INR savings in close to 27 months.

I am keen to have a 5kW unit at home connected to grid with net metering setup. I contacted MESCOM (which happens to be local DISCOM) and they seem to responsible for feasibility and some more technical inputs nothing more.

I have reached out to Tata Solar and will explore other options.

Do you happen to know if it is DISCOM or Solar provider or banks responsible for subsidy/incentive reimbursement ?

Did you manage to get some info?

Here is my monthly Electricity bill after driving my Nexon EV for 670KMs. I received my Nexon on 11-Oct-20 and the Odo stood at 670KM as on Nov 2nd (Billing date).

Note: I have a 3KW grid tie setup.

Yes, It is already installed and waiting for net meter now. The entire subsidy has now moved from MNRE (Ministry of Renewable Energy) to discoms now. Your electricity board is now supposed to provide subsidy, rules differ from state to state. For Haryana it is DHBVN and below are the broad rules

1. Installation to be done by empanalled installers only
2. Solar Panels should be of Indian make
3. Rates defined by DHBVN is 45000 / KW
4. Subsidy - 40% on first 3 KW and 20% from 3-10 KW
5. Subsidy is paid directly to installer and all follow up is done by them

Link with more details - https://esolarconn.dhbvn.org.in/

Everything was done for me by my installer and I did not had to step out even once.

Cheers

I have successfully installed a 4kW grid connected system. I used Enphase micro inverters, the hiccup I see is low supply voltage from grid which is limiting the micro inverter. Any thoughts on how to boose supply voltage to micro inverter ?

Was your installation done in Karnataka ?
I have been hearing from various installers that the DISCOMs in Karnataka are thinking of scrapping the Power Purchase Agreements (PPA) from April - hence no new PPA's will be done from April

What was the approx cost of the 4kW Enphase system ?

I did near Mangalore , not sure of scrapping part. Cost is approx 70k per kW.

Hi folks,

Looking for some advice regarding Rooftop Installation of 5 kW On Grid system.

I'm located in Thrissur, Kerala. Based on a site survey done by a local company (Rapha Solar Energy Pvt. Lt) a 5 kW On Grid System was proposed by them.

The following are the details of the 5 kw solar grid system:

Inverter - Goodwe/Polycab (5 kW, Model - PSIS-5)
PV Module - REC Solar ( Mono Perc, 410 W capacity/module & Total 13 No's )
Rate per kilowatt - 64,000
Total Amount quoted - 3,20,000 (Includes tax + installation)

Subsidy from KSEB not taken into account as getting it is a huge hassle but I plan to negotiate with the company to reduce the price based on the subsidy scheme. I want to ascertain if this is a reasonable quote based on current market prices. Searching online, I found that 3L is the average rate for a 5 kW on grid system.

Would appreciate any input or advice from knowledgeable members regarding this offer, especially folks from Kerala.

Too high IMO. I haven't asked for prices from any installers, but a good 5kW inverter is available anywhere between 50k-1L depending upon the features they provide and a good panel too costs anywhere between 9-13k. So a decent 5kW system apart from wiring and installation should cost close to 2L. This gives you negotiation room with the installers you are dealing with.

You can also try and get the system installed directly from manufacturers/sellers of inverters like this - https://flinenergy.com/complete_system

I installed a 5kW grid tie system in Feb 2017(Thrissur, Kerala) for 3.3 Lakhs, the quote above looks to be on the higher side.

REC solar panels are supposedly expensive and I think that has driven up the cost in your quote.

The current rates for 5KW grid-tie plant using mono perc panel from vikram, waree or luminous with a single phase inverter from growatt, goodwe or luminous in Thiruvananthapuram is 2.8L to 2.9L inclusive of installation and tax. The current rates are a bit lower compared to 2019 rates when I first enquired.

Thank you for your valuable input Sankar. I also concluded that use of REC Solar may have affected the price, as they are certainly top quality panels. My uncle has done the same type of solar installation, from the same company, and that time they used Canadian Solar panels (Price quoted was almost the same). REC panels have marginally superior performance, according to the company rep and also from internet user reviews. But I'm skeptical panel quality will affect much difference in output, especially at the small residential scale we are doing. Maybe I'm wrong on this point but will definitely negotiate for lower price, since quoted amount is almost same as 2 year's before, for a similar setup.

Thank you ecenandu. Nice to know we are from the same place. I had read your previous posts detailing your solar installation and they were certainly helpful. Would you mind telling me the company that did your work? I could check with them and ask for a quote for comparison. Your price and mine are almost the same even though 4 years have passed.

Thank you rdst_1. I will definitely look into that and bargain using it. I did go through Flin Energy website and the warranty quoted by them does not give me much confidence. Also my utmost priority is availability of local support from a company in case of maintenance and other problems. I will ask for a quote from them nevertheless.

REC and Canadian Solar panels are said to be the best, but like you said I don't know if its value in a residential installation. As I write this a 5kW solar plant is getting installed on the roof here with waree mono perc panels and growatt inverter. The quotes I got from several vendors were in the range I mentioned earlier and finalised with one whom I had contacted in 2019.
