Questions to Ask Before You Hire
These criteria will help you distinguish between professionals and amateurs:
How many years of solar experience do you have?
Do you offer AMC (Annual Maintenance Contracts)?
Could you please share which panel/inverter brands you recommend and the reasons for your choices?
Will I get access to generation monitoring tools/apps?
Please let me know the usual duration for your installations.
What happens if my system underperforms?
How Much Do Solar Panel Contractors Charge?
Solar contractor charges are generally 10–15% of the total system cost. For example:
A 3kW system might cost ₹1.6–₹2.2 lakhs installed
Of that, ₹20,000–₹30,000 goes toward labor and logistics
Prices increase for:
Large commercial systems
Off-grid setups (battery + charge controller)
Remote-area logistics
Advanced mounting (e.g., elevated structures)
Always get a written, itemized quote.
Importance of AMC (Annual Maintenance Contract)
Solar panels need cleaning, inspection, and software checks to run efficiently over time.
Ask your contractor if they offer:
Bi-annual panel cleaning
Fault detection and fix
Inverter firmware updates
Generation report analysis
A good AMC keeps your ROI intact and extends system life.

🚫 Can’t show certifications
🚫 Doesn’t provide written documentation
🚫 Pushes you into a fast decision
🚫 Doesn’t offer a site visit
🚫 Offers unrealistic ROI projections
🚫 Requires full payment before work begins
