Residential cost factors For homes, the main cost drivers are system size, roof structure, inverter type, net-metering work, and whether the system is on-grid or hybrid. Eligible residential customers should also consider the current solar subsidy in Kerala, but subsidy should be treated as a process, not an instant discount unless the finance route clearly says so. Commercial cost factors Commercial solar often needs stronger engineering, safety documentation, higher-capacity protection, installation sequencing, and monitoring. The right cost comparison includes ROI, downtime planning, roof strength, energy load profile, and maintenance. How to compare quotes Check panel and inverter brands Confirm structure material and warranty Ask whether earthing, ACDB/DCDB and surge protection are included Compare expected generation assumptions Confirm service response and monitoring support The cheapest quote can become expensive if generation is poor or service is weak. The best quote is clear, technically complete, and suited to your roof.
