A typical 1kW system costs around ₹65,000–75,000 before subsidy, and a 3kW system costs around ₹1.8–2 lakh before subsidy. After the government subsidy under PM Surya Ghar (up to ₹78,000), your actual cost reduces significantly. Use our free Solar ROI Calculator for an exact estimate based on your electricity bill.

This depends on your monthly electricity consumption. As a rough guide: a 2BHK home using 200-250 units/month typically needs a 2kW system (4-5 panels of 400-440W each). A larger home using 400+ units/month may need 3-4kW (7-9 panels). Our engineer provides a free site visit to give you an exact recommendation based on roof space and shadow-free area.

Solar panels typically come with a 25-year performance warranty from the manufacturer, meaning they continue producing at least 80% of rated output after 25 years. Deepu Siva provides a 5-year workmanship warranty on installation, mounting structure, and wiring. Inverters usually carry a 5-10 year manufacturer warranty separately.

Yes, solar panels still generate electricity on cloudy days, though at reduced efficiency (typically 10-25% of peak output). During monsoon months, overall generation drops but doesn't stop completely. Tamil Nadu receives strong sunlight for most of the year, making solar a reliable investment even with seasonal variation.

As a general rule, 1kW of solar requires approximately 80-100 sq ft of shadow-free roof area. So a 3kW system needs roughly 250-300 sq ft. Our free site assessment measures your exact available area and checks for shading from trees, water tanks, or neighboring buildings that could reduce output.

Solar systems require minimal maintenance — mainly periodic cleaning of panels (every 2-3 months) to remove dust, which can reduce efficiency by 5-10% if neglected. We recommend an annual inspection of wiring, inverter, and mounting structure. Deepu Siva offers AMC (Annual Maintenance Contract) packages for hassle-free upkeep.

Physical installation of panels, mounting structure, and inverter typically takes 1-2 days for a residential system. However, the complete process including net metering and TANGEDCO approval can take 30-45 days due to government inspection timelines, which we actively follow up on for you.

PM Surya Ghar: Muft Bijli Yojana is a Central Government scheme launched in February 2024 to encourage rooftop solar adoption across India. It provides a direct cash subsidy (Direct Benefit Transfer) into your bank account after installing solar panels — up to ₹78,000 for a 3kW system. The goal is to enable 1 crore households to generate their own electricity and receive up to 300 units of free power per month. See our full scheme details and countdown page.

New registrations on the official portal were closed from 6 June 2026. However, if you registered before this date, you are still eligible for the subsidy provided your installation is completed before 31 March 2027. Contact us immediately if you registered earlier and haven't installed yet — we can fast-track your installation before the deadline.

The subsidy is tiered by system size: ₹30,000 for a 1kW system, ₹60,000 for a 2kW system, and ₹78,000 for systems of 3kW or above (this is the maximum, regardless of how much larger the system is). The subsidy typically covers around 40% of the total installation cost.

The subsidy is transferred directly into your Aadhaar-linked bank account via Direct Benefit Transfer (DBT) — not as a discount on the invoice. This happens after your installation is complete and the net meter inspection is approved by TANGEDCO, typically within 30 days of approval.

Indian residential homeowners with a valid electricity (TANGEDCO) connection are eligible. This includes individual houses, apartment owners (with society approval for rooftop access), and farmers with a separate residential connection. Commercial, industrial, and HT (High Tension) connections are NOT eligible under this residential scheme.

You'll need: Aadhaar card, a recent electricity bill (showing your consumer number), bank account details (Aadhaar-linked, for DBT transfer), and proof of property ownership or residence. Deepu Siva assists with the entire registration process so you don't have to navigate the portal alone.

Yes, beneficiaries under PM Surya Ghar are eligible for collateral-free bank loans at concessional interest rates (typically around 7%) for the portion of the cost not covered by subsidy. Several public and private banks participate in this scheme. We can guide you on the loan application process alongside your solar installation.

Deepu Siva Pvt Ltd is an experienced solar installer in Coimbatore who handles the entire process for you — free site assessment, portal registration assistance, vendor coordination with TANGEDCO, professional installation, net meter follow-up, and subsidy tracking. This saves you significant time and avoids common application errors that delay subsidy payment.

We offer custom metal fabrication including structural steel work, industrial sheds, PEB (Pre-Engineered Building) structures, GI roofing sheets, solar mounting structures, gates, railings, and custom industrial equipment fabrication. We work with MS (Mild Steel), GI (Galvanized Iron), and stainless steel.

Yes, industrial roofing is one of our core specialties. We install GI sheet roofing, insulated roofing panels, and structural steel trusses for factories, warehouses, and industrial sheds across Coimbatore and Tamil Nadu. Our roofing solutions are designed to handle monsoon loads and provide long-term durability.

Absolutely — this is one of our biggest advantages. We design and fabricate the steel mounting structure AND install the solar panels on top, all from one team. This means better load calculations, faster timelines, and no coordination issues between separate vendors. Many factories choose us specifically for this integrated solar + structure capability.

PEB stands for Pre-Engineered Building — a steel structure designed and fabricated in a factory setting, then assembled on-site. PEB structures are faster to construct, more cost-effective, and ideal for warehouses, factories, and large industrial sheds. Yes, we design and erect PEB structures as part of our structural engineering services.

Fabrication pricing depends on the type of steel used, total weight/tonnage required, design complexity, and site location. We provide GST-compliant quotations with a detailed breakdown after a site visit and requirement discussion. Bulk material orders are also available through our online shop with B2B pricing.

Timelines vary by project size, but a typical medium-sized industrial shed (structure + roofing) takes approximately 4-8 weeks from design approval to completion, depending on weather conditions and material availability. We provide a clear project timeline during the quotation stage.

Yes, all B2B orders come with proper GST tax invoices showing SGST and CGST breakdown. Our online shop supports both B2B mode (with GSTIN, exclusive pricing) and B2C mode (inclusive retail pricing) so businesses and individuals both get the correct invoice format for their needs.
