Solar Installation in Kayathar
From the first phone call to the day your TANGEDCO meter runs backwards — a complete solar installation service, not just the hardware.
A complete solar installation in Kayathar is a great deal more than bolting panels to a roof. It is a joined-up service that begins with understanding your electricity consumption and ends only when your TANGEDCO bi-directional meter is live and your PM Surya Ghar subsidy application is filed. Everything in between — the system design, the procurement, the structural work, the electrical connections, the safety testing, the net-metering paperwork — is part of the same job, and it all needs to be done by one accountable team that sees it through from start to finish.
Kayathar residents who have watched the wind-energy industry develop nearby understand this perfectly. The wind farms in this area were not installed by someone who turned up with a turbine and left. They came with a full engineering and commissioning team that stayed until the power was flowing. Rooftop solar works at a much smaller scale, but the principle is the same: the quality of the final output depends on every stage of the process being done correctly, not just the visible hardware.
Green Point Solar handles the complete solar installation journey for homes and businesses in Kayathar. We are based in Kovilpatti, a short distance up NH-44, and we operate across Thoothukudi district as part of our regular coverage. Our MNRE-approved status means we are authorised to carry out PM Surya Ghar subsidy installations and manage the full TANGEDCO net-metering process — there is no need to engage a separate agent for any part of this.
Stage 1 — Site survey and consumption analysis
Every solar installation begins with a free on-site survey. We visit your Kayathar property and carry out a thorough assessment: measuring the roof area, mapping any shading from trees, tanks, or neighbouring structures, checking the roof's structural integrity and orientation, and reviewing your last few TNEB electricity bills. This is not a sales visit — it is an engineering assessment. The output is an accurate picture of how much solar your roof can realistically accommodate and how much of your electricity bill it will offset.
Many installers skip this step or do it superficially over the phone. That produces a system that is either too large for your available roof or too small to have a meaningful impact on your bill. Our survey report is the foundation of the design that follows.
Stage 2 — System design and written proposal
Based on the survey, we design the system: the number and layout of panels, the inverter specification, the mounting structure type for your specific roof, the cabling route, and the location of the inverter and generation meter. This design is translated into a written proposal that specifies every major component by brand and model, provides a monthly generation estimate in units, and gives you the full cost broken down into supply, installation, and any civil works — before and after the PM Surya Ghar subsidy.
Sizing for Kayathar's climate and your consumption
Kayathar's high solar irradiation — typically 5.5 to 6 kWh per square metre per day — means a well-sized system here generates around four to five units per installed kilowatt per day. But sizing is not just about the climate; it is about matching the system to what you actually consume and when you consume it. A household that runs heavy loads in the evening benefits from a larger system or battery storage to self-consume more. An agricultural connection that runs pumps during daylight hours is a natural fit for on-grid solar with maximum self-consumption. We design around your actual pattern, not a generic template.
Stage 3 — Procurement and delivery
We source Tier-1 solar panels and inverters from established manufacturers and deliver them to your site before installation day. You receive copies of the manufacturer datasheets and warranty certificates as part of the handover documentation — this is important because these documents are what you will need if a warranty claim ever arises, and they should come from the panel manufacturer directly, not from the installer. We do not substitute components without informing you — the brand and model in your proposal is what arrives on your roof.
Stage 4 — Installation
Our in-house installation team carries out all the structural and electrical work. The sequence for a typical Kayathar home looks like this:
- Mounting rails or frames fixed to the roof with appropriate anchors for RCC or sheet roofs, wind-load rated and torque-tightened.
- Solar panels placed and clamped into the rails, with inter-panel DC wiring (MC4 connectors) forming the string circuits.
- DC cabling run from the roof to the inverter location in UV-protected conduit, with a string combiner box where required.
- Inverter mounted on a shaded wall, AC wiring connected to the distribution board with appropriate isolation switches and MCBs.
- Panel frames, rails, and inverter chassis earthed to a buried earth electrode; DC surge protection device fitted.
- System tested: open-circuit voltage, insulation resistance, inverter startup, and live generation verified before handing over.
Stage 5 — Net-metering application and TANGEDCO coordination
Once installation is complete, we submit the TANGEDCO net-metering application on your behalf. This involves providing the technical documentation, the load details, and the completed application form to the local TANGEDCO office. We then coordinate the inspection visit, attend with our technical team to answer queries, and follow up until the bi-directional meter is installed. In our experience, inspections proceed smoothly when the installation is done to standard from the start — which is exactly why we do not cut corners in Stage 4.
Stage 6 — PM Surya Ghar subsidy registration
Parallel to the TANGEDCO process, we register your installation on the PM Surya Ghar national portal and submit the required documents — your Aadhaar, bank account details, electricity consumer number, and installation photographs. The subsidy — up to ₹78,000 for a 3 kW or larger system — is disbursed directly to your bank account after the installation and net-metering are verified. We track the application status and notify you when payment is processed.
Why our end-to-end approach matters
Solar installations fail — or underperform — most often because responsibility is fragmented. The supplier blames the installer; the installer blames the subsidy agent; nobody takes ownership. Our end-to-end service means there is exactly one company responsible for everything, and you know exactly where to call if anything needs attention, now or ten years from now.
