The Two National Players You'll See Everywhere
If you search "solar company Hyderabad," these two dominate the paid and organic results nationally. Both are well-funded and capable — but both also have a documented pattern worth knowing before you sign.
SolarSquare
SolarSquare raised a ₹510 crore Series C in 2026 (led by B Capital, following a $40M Series B from Lightspeed), and operates across 29+ cities including a dedicated Hyderabad presence. Their GoodZero™ plan is a genuine differentiator — a money-back guarantee if actual generation falls short of a committed savings figure, plus 5 years of free maintenance. Their WindPro Mount™ is IIT-Bombay tested for 170 km/hr winds with a ₹1 lakh leakage warranty attached, which matters in Hyderabad's monsoon season. They publish real rupee pricing on their site before any form-fill — a transparency practice worth expecting from anyone you quote.
Where customers report friction: a recurring theme in Trustpilot reviews is post-installation net-metering and DISCOM coordination — one Hyderabad customer reported an incorrectly sanctioned load, non-functional net metering, and 30+ unanswered calls to their assigned rep before escalating to the Consumer Grievance Redressal Forum. At SolarSquare's scale, your point of contact is a rep in a large team, not a decision-maker.
Freyr Energy
Freyr Energy has raised roughly $13M+ from backers including Schneider Electric's energy-access arm and EDFI ElectriFI, and runs its own Sunpro app for install tracking and generation monitoring. They offer real financing tie-ups with EMIs starting around ₹1,466/month.
Where customers report friction: of their public reviews, a meaningful share are 1–2 star, with a recurring, specific complaint pattern — a customer pays the advance, and the sales team goes quiet for weeks before installation actually happens. One dated case: ₹15,000 paid, materials not delivered for nearly two months, net meter still pending. Freyr's own cancellation policy states the advance is non-refundable under all circumstances, which is exactly the scenario driving those complaints. Worth asking directly: what happens if I need to reach you after I've paid?
What to Look for in a Solar Company
1. MNRE / TSREDCO Empanelment
Only empanelled installers can process PM Surya Ghar subsidies. Always ask for their empanelment certificate.
2. Workmanship Warranty (Not Just Panel Warranty)
Every solar panel comes with a 25-year manufacturer warranty. What matters is the installer's workmanship warranty — this covers mounting, wiring, and labour. Look for minimum 5 years.
3. DISCOM Paperwork Handling
Net metering application, DISCOM inspection, bi-directional meter installation — a good company handles ALL of this. If they ask you to do the DISCOM paperwork yourself, find another installer.
4. Post-Installation Support
Solar systems need occasional cleaning and monitoring. Ask if they offer AMC (Annual Maintenance Contract) or at least respond to service calls.
5. Google Reviews
Check Google Maps reviews — not just the star rating, but read the actual reviews. Look for mentions of "after-sales service" and "paperwork handling".
6. Does the Company Stay Reachable After You Pay the Advance?
This is the single most common complaint we hear from customers who switched to us from a larger installer: pay the advance, then the sales team goes quiet for weeks. Ask directly — will I have one named contact throughout, or a different rep each time I call? Is any part of the advance refundable if there's an unreasonable delay? A company that hesitates to answer either question is telling you something.
Price Comparison (3 kW Residential System)
| Company | Price Range | After Subsidy |
|---|---|---|
| National brands (Tata, Freyr, SolarSquare) | ₹2,00,000 – ₹2,60,000 | ₹1,22,000 – ₹1,82,000 |
| Regional leaders (Truzon, Ksquare) | ₹2,00,000 – ₹2,40,000 | ₹1,22,000 – ₹1,62,000 |
| Sri Ishaan Solar | ₹2,10,000 | ₹1,32,000 |
| Other local installers (Punarvi, AB Solar) | ₹1,80,000 – ₹2,20,000 | ₹1,02,000 – ₹1,42,000 |
Prices vary based on panel brand, inverter type, and roof condition. Always get 3 written quotes before deciding.
Our Honest Take
If you want the biggest brand name and don't mind being one of thousands of customers, SolarSquare or Freyr are capable, well-funded choices — just go in aware of the net-metering and responsiveness patterns above. If you want the most established local track record, Truzon has been at this since 2008. If you want a local installer with a genuinely sharp trust guarantee, AB Solar Power Systems' ₹1 lakh leakage guarantee is worth asking any competitor to match.
If you want a named contact from survey to commissioning, DISCOM paperwork handled end-to-end, and a written quote before any advance is collected — that's us. We're not the biggest, and we don't pretend to be. Every installation gets the founder's direct attention, not a call-center queue.
Frequently Asked Questions
How do I choose the best solar company in Hyderabad?
Key checks: (1) TGREDCO empanelment — mandatory for PMSG subsidy; (2) ALMM-listed panels — required for subsidy eligibility; (3) Written warranty document; (4) Net metering experience with TGSPDCL/TGNPDCL; (5) No 100% advance before installation. Sri Ishaan Solar is TGREDCO registered (Reg. TSRE260936).
What is TGREDCO empanelment and why does it matter?
TGREDCO (Telangana Renewable Energy Development Corporation) empanelment is mandatory for solar installers to process PM Surya Ghar subsidy for Telangana customers. Installing with a non-empanelled company means you forfeit the ₹78,000 subsidy. Always verify the installer's TGREDCO registration number.
What red flags should I watch for when hiring a solar company?
Red flags: asking for 100% advance payment before installation; no written quotation; offering non-ALMM panels; promising subsidy before sanction letter; no physical office or verifiable address; no GST invoice. Always get 3 quotes before deciding.
What happens if a solar company goes silent after I pay the advance?
This is a documented complaint pattern with at least one large national installer — advance paid, then weeks of unanswered calls before installation. Protect yourself: get a written payment schedule tied to project milestones (not 100% upfront), confirm you'll have one named contact throughout, and ask directly whether any part of the advance is refundable if there's an unreasonable delay.
