Questions, Answered.
Straight answers from our engineers - no jargon, no sales speak.
Which solar brand is best for NCR weather? +
For North Indian conditions with high temperatures, N-Type TOPCon panels from Adani or Waaree are ideal due to lower temperature coefficients (-0.29%/°C vs -0.34%/°C for PERC).
What is ALMM certification? +
ALMM (Approved List of Models and Manufacturers) is MNRE's mandatory list. Only ALMM-listed panels qualify for the PM Surya Ghar subsidy of up to ₹78,000.
Which inverter brand does Varka recommend? +
For residential use, we recommend Solis S6 Hybrid for best ROI. For industrial/commercial, SMA Tripower remains the gold standard for uptime and asset protection.
What is the actual price difference between brands? +
Sticker prices differ by 5-12% between the brands above, but 25-year generation difference usually exceeds the price gap - the audit models both, and we recommend whichever wins for your roof.
Can I mix panels from different brands on one roof? +
Technically yes; practically we advise a single brand per array so one warranty and one degradation curve covers the whole system - mixing creates fault-diagnosis ambiguity for decades.
