Guide Why you should install a solar rooftop system

Kloud said:
More questions for you,

1. When did you get your solar setup?
2. Do you have a single phase or 3 phase connection?
3. What have you done to deal with the power outages?

3 phase since my existing supply is 3 phase but you can get up to 5 or 6kw approved for single phase supply also.

as for power outages and backup, thats a completely different problem set which is totally unrelated to a solar setup.
an on-grid solar setup anyway shuts down when there is a power outage .

The solar inverter output links up to the mains supply before your house MCB so whatever existing backup setup you have (eg DG in my case but could very well be an inverter elsewhere) will continue to work as is

So, I guess only one of the meters is a net-meter, correct?

I asked because I thought we would have an on-grid solar inverter that also functions as a backup by now.

The existing meter gets replaced with a net meter at time of commissioning.
At end of month, the meter reading will include 3 elements viz total produced, total in (from grid) and total out (to grid)
You will be billed for total in minus total out

Regarding your second question, there is no added advantage of storing power on the solar output end.
You are better off using a normal backup method (traditional inverter) instead

One neighbor inquired at a local solar installer.

He was quoted 185k for a 3KW on grid setup. (Waree bifacial panels + Waree inverter). He'll get 78k back as subsidies.

So net cost 107k.

I checked the prices of these, and both panels and inverter combined retail cost 100k on Waree's official site.

Could someone clarify where the remaining 85k expenses were allocated?

I know wiring, installation, net meter costs money, but 85k? There's no new scaffolding expense as it's already there.

Neighbor also inquired at Solar Square brand and was quoted 221k (143k after subsidies). Is this brand good?

Markup for the subsidies. The "benefit" for going through that process for subsidies is probably tax related.

That could be the most likely case.
The "Subsidy" amount NEVER reaches or benefits the actual end consumer.
The Prices are "adjusted" to ensure the end consumer pays the FULL amount (without subsidy) to the "Agency". The EXTRA Amount (over and above the cost of the actual hardware/equipment) is the "Commission" of the agent. And it is the "Price" that end consumers have to pay IF THEY WANT to opt for Net-Metering, which is ONLY POSSIBLE if end consumers go through these "Approved" Agencies.
Remember, you CANNOT opt for On-Grid Solar Inverter plant if You decided to DIY the entire project. In other words, you do not Qualify for the Government Subsidy. And you CANNOT earn by selling the surplus power back to the Electricity Discom.
***************************************************************************
Moreover, the Subsidy is a Trap because you are FORCED to opt for Lower Quality and Lower Output Solar Panels as ONLY THESE Solar Panels are part of the "Government Approved" Equipment List.
If ANYONE has been able to buy the LATEST Solar Panels with the HIGHEST Wattage output AND got the same approved for Subsidy as well as Net Metering, please let us know.

That's what I thought. I asked my neighbor for the list of other items the agency is providing.

He was given this breakup:

How much do other things cost, roughly?
 
Can anyone share their experience for a Solar Installation?
I am currently looking into an on grid setup with Micro-inverters for my parent place.

It isnt per se
- There is a fair bit of physical work and manual labor in the setup
- Existing scaffolding, unless at the right solar angle will still need some work (depends on your exact location - its approx 19 degress south facing for pune)
- The cost of cabling etc is not miniscule (high DC currents), good cabling from roof top to meter.
- The setup will require dedicated electrical Grounding wrk - fairly heavy grade
- The Electricity board approval process is painful, time consuming and involves under the table payments
- Installer has to make some profit in lieu of time and effort

70-80K for the above is not too bad

There is a fair bit of physical work and manual labor in the setup - True, but that doesn't justify nearly double the price of Panels and Inverters.
Existing scaffolding, unless at the right solar angle will still need some work - The previous installation should have this factored in.
The cost of cabling etc is not miniscule (high DC currents), good cabling from roof top to meter. - With Micro-Inverters, this cost drops significantly.
The setup will require dedicated electrical Grounding work - fairly heavy grade - Standard 0.5sq.mm to 1sq.mm single core Copper wire is more than enough if Micro-Inverters are used. Moreover, digging and installing a grounding road isn't expensive.
The Electricity board approval process is painful, time consuming and involves under the table payments - VERY TRUE. The Corruption could the BIGGEST Part of the bill as a LOT of Money may be needed for quick or timely approvals without the Discom Babus raising "Discripancies, Queries, or Objections" just to delay the project and escalate costs.
Installer has to make some profit in lieu of time and effort - Some, is understandable. But they are NOT using Latest Panels with the HIGHEST Wattage output. They could literally be disposing off OLD Solar Panels, which would be available at a significantly reduced price to make way for new stock and industrial customers.
