Under 10 kW, no grid support charge. Above it, there is one.

A detail that changes the financial model on mid-sized commercial rooftops.

Grid support charges apply only to systems above 10 kW. Smaller systems are exempt.

For a small hotel, a clinic or a showroom sitting right around that line, the correct answer is not automatically 'go bigger'. Sometimes two smaller connections, or a slightly restrained system size with better self-consumption, produces the better net position.

This is exactly the kind of thing a spreadsheet answers and a sales pitch does not.

Send us twelve months of bills and we will model it properly.

Same house. Same family. Same month, one year apart.

[TO CONFIRM — TEMPLATE. Requires a real customer's before/after KSEB statement and written consent.]

This is the single highest-performing post format in solar marketing, and the only one that cannot be faked without it eventually costing you.

Rules we will hold ourselves to:
• Same billing period, year on year, so seasonality is not doing the work
• Consumer number and personal details masked
• The system size stated, so the comparison is honest
• Any subsidy received disclosed

A saving shown without the system size is a number without a denominator. We will always show both.

Every component. Every cost. On one page, before you decide.

Transparent Pricing is our second value and it is the easiest one to test. Ask for the proposal.

Ours is itemised: panels with make and model, inverter, mounting structure, cabling, protection devices, earthing, labour, net metering assistance, and taxes. Line by line.

What that prevents:
• Inflated specifications you did not need and cannot evaluate
• A cheap component hidden inside a competitive-looking lump sum
• 'Extras' that appear after the advance is paid

Kerala buyers consistently name transparent pricing as the deciding factor in choosing an installer. We agree with them, which is why it is written into our values rather than into a promotion.

Ask any installer for a line-item quote. Watch what happens.

Send one photo of your KSEB bill. Get back a real savings number.

No site visit required for this first step. No form to fill. One photograph.

We read the four numbers that matter — units consumed, sanctioned load, tariff slab and consumer number — and come back with:

• A realistic system size for your consumption
• An estimated monthly saving in rupees
• Your PM Surya Ghar subsidy eligibility and likely amount
• Which metering arrangement you would fall under at that size

That is genuinely useful information whether or not you buy from us.

WhatsApp your last bill to [WHATSAPP]. Usually back within one working day.

Free site assessment. Ninety minutes. No obligation, no sales pressure.

We come to your roof and tell you the truth about it.

Included: roof survey and usable area, shading analysis across the day, structural and waterproofing check, electrical review and meter position, and a twelve-month bill analysis.

You get a realistic system size, a realistic generation estimate, and a straight answer on your PM Surya Ghar eligibility.

If your roof is not right for solar, we will tell you that instead. It happens, and saying so is cheaper for everyone than installing something that disappoints.

Booking this week across all 14 districts. Call +91 98464 60494 or fill the form at terawattindia.com/contact.php

Terawatt Energy Solutions. Trivandrum. Eight years of Kerala rooftops.

We are a homegrown solar EPC company based in Trivandrum, working across Kerala.

EPC means we handle the whole thing: site assessment, system design, supply of panels and inverters, installation by our own certified crews, the KSEB net metering file, testing and commissioning, and the maintenance afterwards.

One company. One point of accountability. Nobody to point at when something needs fixing.

We started because too many installations in Kerala were compromising on design, on component sourcing, or on what happened after handover. Usually all three.

Sasthamangalam, Thiruvananthapuram. Technicians across the state.

Eight steps from your first phone call to a system that pays you back.

1. Free site assessment — roof survey, shading study, structural check, bill analysis
2. Custom system design — layout and electrical drawings engineered for maximum yield
3. Itemised proposal — every component and every cost listed
4. Supply — Tier-1 panels and inverters from leading global brands
5. Installation — our own certified crews; mounting, wiring, safety compliance, clean site
6. KSEB net metering — application prepared and filed, inspection coordinated, approval chased
7. Testing and commissioning — full electrical safety and performance testing before handover
8. AMC and monitoring — scheduled cleaning, remote dashboards, priority repair visits

One company for all eight. That is what EPC means, and it is the reason there is nobody to blame but us.

₹78,000 from the government. Four conditions decide if you get it.

PM Surya Ghar Muft Bijli Yojana, in plain English.

You qualify if:
1. The connection is residential. Commercial and industrial are excluded.
2. Your sanctioned load is 10 kW or below.
3. You have an Aadhaar-seeded bank account — the subsidy comes by direct transfer.
4. You install through an MNRE-empanelled vendor with compliant equipment.

Miss any one and the money does not come. We have watched customers lose it on the bank account detail alone.

We handle the portal registration, the DISCOM feasibility, the technical approval and the net metering file. You handle the roof.

3 kW is now the most important number in Kerala solar.

Under the new rules, 3 kW is the ceiling for true net metering on a domestic connection.

Go above it without a battery and you shift into net billing, where surplus is bought back at a feed-in tariff instead of credited unit-for-unit.

That does not automatically make bigger systems wrong. A house with heavy daytime load — AC, pump, work-from-home — often still wins at 5 kW because it self-consumes most of what it makes.

It does mean the honest answer to 'what size should I install?' is now 'show me your bill first.'

Anyone quoting you a size over the phone is guessing with your money.

Kerala changed the rules on solar in January. Most people still don't know.

The KSERC 2025 regulations took effect on 6 November 2025 and the new billing system went live on 1 January 2026.

There are now three ways your solar can talk to the grid:

• Net metering — up to 3 kW (5 kW with battery). Exported units credited against your bill, exactly as before.
• Net billing — up to 500 kW. Surplus paid at a feed-in tariff, 1.5x standard rate during peak hours.
• Gross metering — up to 3 MW. Everything exported at 125% of SECI rates.

Which one you land in is decided by system size. Which means sizing is no longer just an engineering decision — it is a financial one.

We size on your actual bill data, then show you the numbers under each option before you commit.
