Buying rooftop solar guide
Buying rooftop solar involves more decisions than most homeowners expect — system sizing, panel technology, mounting structure, vendor selection, and subsidy paperwork all affect your final cost and long-term savings. This guide walks through the process in five steps.
Step 1 · Is solar right for you?
Before you begin your journey, you must ensure that investing in solar makes sense for you — including cost, system sizing, panel type, and battery decisions.
Step 2 · Get quotes and compare them
Find multiple installers in your local area and request quotations for your property.
Step 3 · Make a decision and choose an installer
The system price, though important, should never be the only factor for deciding an installer.
Step 4 · Common pitfalls while buying
Purchasing rooftop solar is a long term investment and hence, it's important that you avoid common pitfalls while purchasing solar for your home.
Step 5 · Choose the right mounting structure
Your roof type — RCC, tin shed, or elevated structure — determines which mounting structure is appropriate, affecting durability, cost, and installation approach.

What are the steps to buying rooftop solar in India?
Broadly: (1) confirm solar makes financial sense for your roof and consumption, (2) get quotes from multiple installers and compare them on a like-for-like basis, (3) choose an installer based on credentials and service quality, not price alone, (4) avoid common buying pitfalls like unclear quotations and low-price bias, and (5) confirm the right mounting structure for your specific roof type.
