My bad. Looks like DDIS has a off-grid setup.
I too am interested to understand the redtape related aspects to an on-grid solution.

The prices of solar modules and solar inverters have been falling over the past year. A recent study by solar consultancy Bridge to India showed that module prices had dropped 29% in the past year and 8% in the past quarter. Inverter prices too dipped 21% year-on-year and 5% in the last quarter. Most solar modules used in India are imported, primarily from China. The rupee too has been strengthening against the dollar in the first months of 2017 and currently stands at Rs64.65.

Last month, the whole sale prices of electricity in California became 0 even going into negative due to surplus power production from Solar. The Solar production crossed 50% of total power generation between 8AM to 2PM.
2% to 50% took just 10 years for California and The Govt simply cannot allow more solar production until they figure out an alternative to store the surplus energy. It would be an interesting year ahead.

Zero cost of electricity plus electric drive transport systems without the use of batteries like the metro and trams can greatly help reduce mobility related pollution.
However my faith in the government machinery to enable such a state to be achieved in Blore is very low.

We had heavy rains in June, the solar production was 398 Units approximately 13.3 units a day. Which is 4 units down per day from what we got during summer. But even then it isn't that bad. If it is raining through out the day, the production will be around 4-8 units, I think we got the 13.3 average because of few sunny days in between.

I have 2 KW unit and on sunny days getting 8-9 units and on cloudy days 4-6 units and on rainy days 3 units. My consumption is 10 units per day.

Previously on KSEB website, I could see separate reading for solar export to the grid and consumption from the grid. Now, I am not able to see that information. Anyway, for the last three months we were supplying excess to the grid and the electricity bill was only 92 INR.

This is the screenshot from the KSEB website, I think 349 units is the excess supplied to the grid.

The new range of Hybrid Grid Inverters have started hitting the market. These inverters are Grid-Tied systems with Battery backup. In short it is both a Grid-Tie and an Off-Grid system in one unit.

I could only find 3 manufacturers selling it here in India. Schneider and Studer are officially selling imported units, but costs a bomb (4 times the cost of normal Grid Tie). I saw another manufacturer FlinSlim selling rebranded Chinese Inverter with same features. Once other manufacturers starts selling these inverters, the prices will come down significantly.
FlinInfini Smart and Lite models on their site now

Default Re: Using Solar / Wind Power in India (EV charging, home etc.)

Hello Friends,

I have a farm at Panna, Madhya Pradesh, since it is bordering the forest and far from the village, there is no electricity over there.
I have the option to procure a separate Transformer for the same or I can stay off the grid. I am interested in staying off the grid, but I have no clue how or where to start.
The farm is going to have a 3-4 huts with lights and fans. There won't be any TV but we will need a fridge (in the future).
I am also planning to have stand alone Solar lamps for the compound lighting. We are also getting a bore-well dug, and we would need to have an electric pump to fill up the tank - can this be done through solar as well?

My questions

- What should be the power output that I should be looking at
- Which companies, manufacture these, what components are required (panels, inverter, charge controller, batteries (what type))
- What is the cost of setting up a total off-grid set-up
- Can trained electricians do the job for me or do we need specialists to install - asking as since the region is remote, availability of specialists may be an issue

Thanks a lot in advance!

Cheers,
Trojan
