Questions, Answered.
Straight answers from our engineers - no jargon, no sales speak.
What panel specifications should I look for in solar panels? +
Key specs: efficiency (>21% for Tier-1 N-type), degradation rate (<0.4% annual), temperature coefficient (-0.26%/C or better), and frame rating (4000Pa wind, 5400Pa snow load).
How do N-type panels compare to P-type solar panels? +
N-type bifacial panels (like TOPCon) are 15-20% more efficient, have lower degradation rates, and perform better in high-temperature Indian conditions compared to standard P-type PERC panels.
Does Varka Solar provide product comparison assistance? +
Yes. Varka engineers compare panel and inverter specifications based on your roof type, orientation, shading conditions, and budget to recommend the optimal hardware configuration.
Is this product ALMM-listed and subsidy-eligible? +
Every panel sold by Varka is ALMM-listed - it is a legal condition for grid connection and the PM Surya Ghar subsidy, and we verify the list before quoting.
What happens if this model is discontinued? +
We stock spares and up-front match the module model for warranty replacements; if discontinued, an equivalent-or-better performance panel is substituted under the same warranty terms.
