Heavy Duty Engineering & Fabrication

Leak-Proof Solar Mounting: TATA GI, Apollo GP & Safe Walkways

Kerala's coastal humidity, heavy monsoon downpours, and high wind gusts require superior structural engineering. We fabricate heavy-duty solar mounting structures using genuine TATA GI, Apollo GP with protective primer & anti-corrosive paint, or marine-grade extruded aluminium railings with SS304 stainless steel fasteners.

Whether your property has a flat concrete roof (guaranteed 100% leak-proof with precision chemical anchoring), a metal sheeted roof, or a traditional sloped tiled roof, our custom fabrication ensures maximum structural stability and roof protection. Every installation features dedicated integrated maintenance walkways, ensuring homeowners and technicians can easily and safely access solar panels for routine cleaning and inspection without stepping on modules or damaging roof surfaces.

⚡ KSEB Billing Rule: Kerala domestic consumers without solar receive bi-monthly bills (every 2 months). Once you install rooftop solar and connect a bidirectional net meter, KSEB shifts your account to monthly billing so solar export units and minimum charges are settled every 30 days.
ℹ️ Solar Financing & Subsidy: Low-interest rooftop solar loans are offered by SBI, Canara Bank, other nationalised & scheduled banks, and NBFCs. Apply through the JanSamarth portal or PM Surya Ghar portal. The central DBT subsidy is credited directly to your loan account (reducing principal and EMI), or to your savings account if self-financed.

Estimated 25-Year Lifetime Savings: ₹4.7 Lakhs

Shield your household permanently from future KSEB electricity tariff hikes.

⚡

KSEB Distribution Feeder Quota Advisory

Under Kerala electricity regulations, local distribution transformers can only approve rooftop solar installations up to their designated grid feeder capacity limit. Once the transformer quota fills up in your subdivision, no new solar net metering connections can be approved. Check feasibility for your location before feeder capacity closes.

Got Questions?

Frequently Asked Questions About Solar in Kerala

Everything you need to know about PM Surya Ghar subsidies, KSEB net metering, battery backup, and financing.

How much government subsidy do I get under PM Surya Ghar in Kerala?
Under PM Surya Ghar: Muft Bijli Yojana, the central government provides a Direct Benefit Transfer (DBT) subsidy of ₹30,000 for a 1 kW system, ₹60,000 for a 2 kW system, and ₹78,000 for 3 kW or larger residential systems. There is no separate state subsidy in Kerala for 2026. Important Update: If you avail a bank loan, the subsidy is credited directly to your loan account to immediately reduce your principal and monthly EMI instead of your personal savings account. For self-financed customers paying upfront, the subsidy is credited directly to your own bank account. As an MNRE-empanelled vendor, Sonetec handles all portal submissions and inspection paperwork on your behalf.
Does rooftop solar work during Kerala monsoon or on rainy days?
Yes. Modern TOPCon N-type bifacial solar panels absorb ambient diffused sunlight through cloud cover, generating 20% to 35% of their rated peak output on rainy or overcast days. In hybrid solar setups with battery storage, the smart inverter seamlessly supplements any shortfall from the battery or grid so your home never notices any difference.
What happens during a KSEB power cut with a hybrid inverter?
A standard on-grid solar system shuts down during a power cut for safety reasons (anti-islanding). However, with a Sonetec Smart Solar Hybrid Inverter with battery storage, the system isolates from the grid within 10 milliseconds. Your lights, ceiling fans, refrigerator, television, and Wi-Fi router continue running without any blackout or equipment restart.
Can I get a bank loan or financing for installing rooftop solar?
Yes! Concessional, collateral-free solar loans up to ₹2,00,000 (and up to ₹6,00,000 for higher capacities) are available from State Bank of India (SBI), Canara Bank, other nationalised banks, scheduled commercial banks, and NBFCs at subsidised interest rates (around 5.75% to 7% per annum) for tenures up to 10 years. You can check eligibility and apply seamlessly through the JanSamarth portal (jansamarth.in) and the PM Surya Ghar portal (pmsuryaghar.gov.in). Under current guidelines, the central subsidy (up to ₹78,000) is credited directly into your loan account, immediately reducing your loan principal and dropping your monthly EMI to as low as ₹1,339/month.
Which districts in Kerala does Sonetec Powers serve?
Sonetec Powers serves four primary districts across South Kerala: Kollam, Thiruvananthapuram, Pathanamthitta, and Alappuzha. We operate our Head Office in Chathannoor (near LM Mall) and regional branch offices in Anchal and Chadayamangalam, ensuring fast on-site engineering surveys and rapid emergency support.
