FAQs

A standard residential solar installation typically takes 1 to 3 days, depending on the system size and roof type. Our team handles everything from structural mounting and wiring to inverter setup and final testing. Larger commercial projects may take 4–7 days.

The central government's PM Surya Ghar Muft Bijli Yojana offers subsidies up to ₹78,000 for residential rooftop solar installations. In Kerala, ANERT (Agency for Non-conventional Energy and Rural Technology) also provides state-level schemes and low-interest loans. Suntropic assists all customers with subsidy applications at no additional charge.

Most residential customers save between 70–95% on their monthly KSEB electricity bill. The exact savings depend on your current consumption, the system size, and sunlight availability. With net metering, you can also sell surplus power back to KSEB and earn bill credits. The typical payback period in Kerala is 3 to 5 years.

High-quality solar panels from brands like Adani, Vikram, and Waaree typically last 25 to 30 years with minimal degradation (around 0.5% per year). Most panels come with a 25-year performance warranty. Inverters generally last 10–15 years. Suntropic only installs panels from brands with proven longevity and strong after-sales support.

Yes! Solar panels continue to generate electricity on cloudy days, though at reduced efficiency (typically 10–25% of normal output). Kerala's tropical climate means abundant sunlight for most of the year. During the monsoon months, a hybrid system with battery storage ensures you still have power when generation dips.

Solar panels require very little maintenance. We recommend a periodic cleaning every 2–3 months (especially during summer when dust accumulates) and an annual inspection of wiring, mounting, and inverter performance. Suntropic offers optional Annual Maintenance Contracts (AMC) to keep your system performing at its best year after year.
