Why the cheapest quote is rarely the best
Solar quotes in India vary widely for the same system size. A Rs 1,20,000 quote and a Rs 90,000 quote for a 3 kW system are not offering the same thing. The cheaper quote may use non-ALMM panels that disqualify you from Rs 78,000 subsidy, an undersized inverter, or skip DISCOM liaison charges that you will pay separately later. The real cost of the Rs 90,000 quote may end up higher than the Rs 1,20,000 quote after accounting for these gaps.
The comparison framework: 6 things to check
📋Empanelment statusVerify the installer on PM Surya Ghar portal before comparing anything else. Non-empanelled means no subsidy.
💡Panel brand and modelCheck if ALMM-listed. Compare efficiency ratings. Insist on Mono PERC minimum, prefer TOPCon.
🔌Inverter brand and capacityShould match system size. Check warranty period. Growatt and Sungrow are reliable entry-level. Delta for premium.
🔧What is includedDISCOM liaison, net metering application, earthing, conduit, monitoring device. Ask line by line.
📅Warranty termsPanel 25yr performance, 10yr product. Inverter 5yr minimum. Workmanship 1-2yr. All in writing.
💰Cost per kW installedNormalize across quotes: total cost divided by system kW. Compare this number, not headline price.

💡
Once you have filled this table for 3 quotes, eliminate any quote with non-ALMM panels or non-empanelled installer immediately. Compare the remaining quotes by cost per kW after verifying all inclusions are equal. Only then does price become a meaningful differentiator.

If a quote is more than 20% below these ranges, ask for a line-by-line breakdown immediately. Below-market pricing almost always involves compromises on component quality or missing services.
Frequently asked questions
Should I always choose the most expensive quote?
No. Price should be a secondary factor after verifying empanelment, ALMM panels, and all inclusions. The best quote is the one with the best quality-to-price ratio after normalizing for what is included. A Rs 1,30,000 quote that includes DISCOM liaison, monitoring device, and quality Mono PERC panels may be better value than a Rs 1,10,000 quote that excludes these items.
What if only one installer in my area is empanelled?
This happens in some tier-2 cities. If there is only one empanelled installer, you have less negotiating power on price but still verify ALMM panels, warranty terms, and payment milestones. You can also ask if they work with a network of other empanelled installers from nearby cities who can do the work.
Is it okay to negotiate on price with solar installers?
Yes, negotiation is normal and expected. Focus on getting a better price on the total package rather than asking for cheaper components. Installers often have flexibility on margin but not on component quality if they want to maintain their empanelment status. Negotiating payment terms (less upfront, more after commissioning) is also fair.
What payment schedule should I insist on?
A typical fair schedule is: 30-40% on signing and material delivery, 40-50% on installation completion, and 10-20% after DISCOM commissioning certificate. This protects you by ensuring the installer completes the full process before receiving final payment. Never pay 100% upfront.
