How to Choose a Reliable Solar Installation Company
By SaveBill Editorial Team. Last updated 2026-11-10.
Your installer decides quality, safety and after-sales support. Use this checklist.
Ask for proof, not promises - Company registration and contact details - Registration or empanelment where a scheme requires it, verified on the official portal - Real project references you can check - Equipment datasheets and warranty documents
Quotation quality Look for itemised models, capacity, structure details, scope of paperwork and payment schedule. See the buyer’s checklist.
Service Ask who handles faults, how fast and whether an AMC is offered.
Red flags - Zero-bill guarantees - Pressure to pay fully in advance - Vague equipment descriptions - No written warranty
Compare before you decide Get two or three quotes and use our process guide to compare scope.
Site visit test A good installer visits the roof, checks shading and your electrical panel, and explains the design in plain terms. A quote produced without seeing the site is a warning sign.
FAQ ### Should I choose the cheapest? Compare scope and warranties first. ### Can I verify an installer? Check scheme portals and ask for references.
