Commercial Solar System in Sattur
Built for Sattur's factories, printing units and industrial enterprises — solar that pays for itself and then keeps paying.
Sattur's economy runs on electricity. The fireworks and safety-match factories along the NH-44 corridor, the offset printing presses, the packaging units — all of them draw significant three-phase power through the day, and all of them pay commercial TANGEDCO tariffs that have risen steadily over recent years. A commercial solar system in Sattur addresses that cost directly: the generation happens on your own roof, consumed on-site before TANGEDCO even records it, reducing the units billed at commercial rates. For a factory with a heavy daytime load, the economics are often compelling within a few years of installation.
What makes Sattur's industrial geography particularly well suited to commercial solar is the rooftop: factory sheds and warehouses in and around the Virudhunagar district typically have large, unobstructed, south-facing metal or asbestos-sheet roofs. A 50-foot by 100-foot shed roof can support a 20–30 kW system without any compromise to production space below. That kind of capacity generates 80–150 units a day — several thousand units a month — which, at commercial tariff rates, translates to a meaningful reduction in the monthly TANGEDCO bill.
Green Point Solar is MNRE-approved and has experience designing and installing commercial and industrial rooftop systems across the Virudhunagar and Thoothukudi belt. We handle the technical design, structure engineering for heavy-gauge mounting on industrial roofs, three-phase inverter installation, TANGEDCO commercial net-metering application and, where applicable, the accelerated depreciation documentation that matters to businesses filing IT returns.
Why Sattur's industrial sector is a natural fit for commercial solar
The core logic of commercial solar ROI rests on self-consumption: the more of your solar generation you consume on-site, the more you benefit, because on-site use avoids the full commercial tariff rather than earning the lower net-metering export rate. Sattur's factories are, in this respect, ideal candidates. Fireworks and match manufacturing typically runs day shifts; offset printing is often a daytime operation. That means power demand is high precisely during the hours when solar generation peaks. The overlap between your factory's load curve and the solar generation curve can be very high — in some cases, a well-sized system produces very close to what the factory consumes during daylight hours.
Accelerated depreciation — the commercial solar advantage
Under the Income Tax rules applicable to businesses in India, solar energy equipment qualifies for 80% accelerated depreciation in the first year of installation. For a business that is profitable and paying tax, this means that 80% of the system cost can be written off against taxable income in Year 1, significantly reducing the effective net cost of the installation. For a factory owner in Sattur paying corporate tax, this depreciation benefit can meaningfully shorten the payback period beyond what the electricity savings alone would achieve. We can provide the necessary documentation for your accountant; the actual tax benefit should be confirmed with your CA based on your firm's specific tax position.
Commercial system sizes — what suits your Sattur business
| System size | Typical business type in Sattur | Approx. monthly generation | Approx. gross cost |
|---|---|---|---|
| 5–10 kW | Small printing unit, shop, office | 600–1,500 units | ₹3.1L – ₹6.2L |
| 10–25 kW | Medium factory, larger printing press | 1,500–3,750 units | ₹6.2L – ₹15.5L |
| 25–50 kW | Large manufacturing shed, warehouse | 3,750–7,500 units | ₹15.5L – ₹31L |
| 50 kW+ | Industrial-scale factory, multi-unit campus | 7,500+ units | Custom quotation |
These are indicative figures. Actual pricing depends on roof type, structure requirements, inverter configuration (single-phase vs three-phase, string vs central), cable run lengths and balance-of-system costs. We prepare a detailed site-specific quotation after the survey — the table above gives you a ballpark for budgeting conversations.
Three-phase solar for Sattur factories
Most manufacturing units in Sattur operate on three-phase TANGEDCO connections, and any commercial solar system we design is matched to that connection type. Three-phase on-grid inverters (or multiple single-phase inverters balanced across phases) ensure that the generation integrates cleanly with your existing electrical infrastructure. We co-ordinate with your electrical team to understand the existing panel and cabling layout before finalising the design, so the solar system adds capacity without creating imbalance or compliance issues.
TANGEDCO commercial net metering for Sattur businesses
TANGEDCO's net-metering scheme is available for commercial and industrial connections, though the application process for HT and larger LT connections has additional documentation requirements compared to residential installations. We have experience handling commercial net-metering applications and manage the complete process: application submission, technical inspection co-ordination, testing and commissioning. For very large systems (above the standard LT threshold), we advise on the appropriate tariff category and application route during the survey stage.
Why Green Point Solar for Sattur commercial installations
Commercial solar is a capital investment, and factory owners rightly treat it with more scrutiny than a household purchase. We welcome that scrutiny. We provide a detailed site report, a generation estimate with seasonal breakdown, an ROI table and references from commercial installations on request. There are no hidden costs and no pressure — just a thorough proposal that lets you make the decision on your own timeline.
Commercial solar installation process
- Site survey: We visit your Sattur premises, assess the roof structure, measure usable area, review your TANGEDCO bills and note your sanctioned load and connection type.
- Design and proposal: We prepare a full system design — panel layout, inverter specification, mounting structure type, single-line diagram and generation estimate — with a detailed cost breakdown.
- Structural assessment: For heavy factory roofs, we confirm the mounting structure specification with the roof material type (steel, asbestos sheet, concrete) to ensure a safe, wind-load-compliant installation.
- Installation: Our team carries out the full installation — panel mounting, wiring, inverter, earthing, AC and DC protection — while minimising disruption to your production schedule.
- TANGEDCO net-metering application: We submit the required commercial documents and co-ordinate the TANGEDCO inspection and bi-directional meter installation.
- Commissioning and handover: Full system test under load; monitoring setup; handover of all documentation including warranty certificates.
