Tata Power Solar is one of India’s oldest and most established module makers, part of the Tata group, with a wide nationwide service network. For a 25-year purchase, that heritage is the main reason buyers pay a modest premium — if a panel underperforms in year 12, you want a company that’s still around to honour the warranty. Its ALMM-listed DCR mono PERC modules qualify for the PM Surya Ghar subsidy. Read the full Tata Power Solar review for pricing, warranty and who it suits.
Waaree is India’s largest solar panel manufacturer, known for competitive value per watt and a broad product range. Its panels are equally ALMM-listed and DCR-compliant, so they qualify for the same subsidy, and typically price a little lower than Tata. If you’re optimising cost per watt without giving up subsidy eligibility, Waaree is a strong candidate. See the full Waaree review for details.
As a rough, indicative guide (2026 — verify current), Tata often lands around ₹30–34 per watt and Waaree around ₹27–31, though real quotes vary widely by city, installer and panel type. Crucially, the brand you pick does not change your subsidy: both are DCR-eligible, so a 3 kW system gets the same ₹78,000 either way. That means the panel premium only affects your base price, not your incentive. Compare full system prices by size to see where a 3 kW or 5 kW system lands.
Both brands follow the industry standard: a ~25-year performance warranty plus a ~10–12-year product warranty (confirm on the specific model datasheet). Generation is essentially identical for a given wattage — about 4 units per day per kW — because output depends far more on your roof, shading and system size than on the logo. Your inverter (a separate 5–10-year warranty) and your installer’s workmanship matter just as much as the panel brand.
The honest answer: the bigger driver of a good outcome isn’t the panel brand — it’s the installer. Both Tata and Waaree are safe, subsidy-eligible, 25-year choices. Decide on total system price, warranty terms and the installer’s track record. If you want to weigh the wider market first, see our solar panels buying guide and all brand reviews.
