Rooftop solar: has anyone installed it? What panels, inverters?

@drupal suru ho jao.

just search here, there was a discussion around it. worth reading

Pmsurya is full scam . 

As only ongrid system is eligible for subsidy and vendors provides 3rd class panels .

It's better to install hybrid or off-grid solar system is good as compared to ongrid.

👇

Non subsidy plant 

3 kw non dcr solar panel = 39000

3kw Ongrid inverter 16000

DCDB,ACDB,LA, EARTHINGS,CABLE, STRUCTURE=14000

Netmeter 1500

Netmetering expense 2000-3000

Total 73000 rupees without subsidy 

Savings 400-450 units per month lower in winters and cloudy days

Subsidy plant

For subsidy plant approved EPC may charge you as per his wish mostly they charge 180000 for 3 kw plant, (and many EPCs charge upto 2 to 2.5 lakh for the same)  considering plant cost 180,000 and 78000 subsidy net cost comes around 102000

I recommend using DCR panels without claiming subsidy to support indigenous solar manufacturers 

@Cardboard

If you want 1kw offgrid plant i suggest you to buy 24 volat 400*2=810 watt waree solar panel from Flipkart or Amazon

Cost will be around 12000 and if you have existing inverter buy an MPPT SMU at Around 5k and convert your existing inverter into solar inverter 

800 watt off-grid plant is ready in 17000 rupees no grid will be needed for batti pankha tv laptop etc 

for rural areas this is best small set-up 

Subsidy - consider you are not going to get it esp State ones. Had seen tons of persons installing these and not getting a penny. Ofcourse you will gonna get less bills.

And do you know if the main electricity is down - those solar are useless and you will still need to rely on other inverter with 1/2 batteries.

No backup plans:

Get a hybrid inverter if not have like Exide Solar Hybrid with 1 battery (12V)

Get 2 (atmost 3) solar panels of around 180/200 watts. Luminous/Waree/Loom Solar. I got Zunsolar mono from Flipkart 5K each

Even running in non hybrid mode - they will still charge your batteries during power cuts. (why non hybrid mode - want to save batteries or increase their life)

And with this setup. Add some wires etc you will be spending max of 11K + 5K (if inverter not available)

What you got: 1 FAN (2 Fan if BDLC) plus your laptop/mini pc and some lights.

I bought these during an extended power cut of around 5+ days and i never need to worry about laptop shut down during work form home. Bought these in 2021 (corona time)

If there is insurance get it. One of my neighbours grid flew during cyclone and one of the panel hit a parked car.

@Cardboard

Non subsidy hybrid plant

3 kw non dcr solar panel = 39000

3 kw Hybrid inverter 40000

4 batteries 150 AH 40000

DCDB,ACDB,LA, EARTHINGS,CABLE, STRUCTURE=14000

Netmeter 1500

Netmetering expense 2000-3000

Total 137500 rupees without subsidy 

Power Savings may vary as per power backup charging and drainage 

I recommended 3kw plant as it would be beneficial and cheaper for you and will be able to push maximum energy possible to grid in whatever grid hours available during sunshine

Please keep in mind these 4x 150 ah batteries can store max 6 units in them if they are fully drained if they are half charged they can take only 3 units only from solar or grid in case of excess solar energy production with batteries fully charged and less load during power outage energy will still be wasted hence keep in mind these calculations,hybrid system storage limitations and energy losses during ac to DC and DC to AC conversions

How to permanently switch to Solar electricity?

Assuming minimum of 400~450 units per month.

Any suggestions would be really appreciated.

@drupal 800 watt off-grid plant is ready in 17000 rupees ?

Bhai installation, mounting cost, wire cost etc kon batayega ? Iska kitna lagega woh bhi batao.

Total batao kitna lagega, agar normal inverter and 1 battery system already ghar me hai toh.

Got it installed at 1.80 Lakh before subsidy for 3KW system. A bit expensive, i would say. Panel: Loom Solar Inverter: UTL.

Generate on average 15 KW per day. Shoot your question if any

Is earthing mandatory?? I don't have any space for it. I will have to break some tiles of my porch . My home's electric connection is grounded. Can I connect the solar's earthing to the present one? @drupal @Rahil42

3kw ongrid ka planning hai next year . Abhi 1 ya 2 kw ke liye best ongrid inverter batao konsa rhega @drupal .

Mere pass already 2.5kw off-grid setup hai last 3 years se . Ab use ongrid me convert Krna hai .

@M.MAHI

Hybrid Solar plant is always better than off-grid

Reasons

1.You get subsidy on hybrid solar plant and no subsidy applicable on off-grid plant

2.Excess energy can be fed back to grid which can be utilised later in hybrid system while in off-grid there is no other provision to store excess energy except into limited capacity batteries 

3.in off-grid plant  batteries has limited capacity to store units in case of fully charged batteries and less load extra produced units go waste

4.Hybrid plant is a little bit costly than off-grid plant but subsidy compensates that extra money spent 

PM - JHOL - KARRING Yojnaa ...

Just run baby run .

if interested just get good imported equipments with warranty , service etc ... 

Do not fall for made in India .... jumlaa

aapney paisey ki rakshaa swayam karen .

Gujarat, On Grid Tier 1 Adani, Waaree Panels, 3.25 KW Bifacial setup, net 80K after 78K subsidy by EPC.

Bookmarked and following. 

Is there income criteria for subsidy??
