Choosing the right solar provider is just as important as deciding to go solar in the first place. With rising demand, the market is flooded with options — but not all are created equal.
Before you sign any contracts or commit to a system, take time to ask the right questions. These aren’t just small details — they can determine how efficient, cost-effective, and stress-free your solar journey will be.
What is the 20% Rule for Solar Panels?
The “20% rule” is a rough guideline suggesting that a solar panel system should cover at least 20% of your roof area to meet an average household’s energy needs.
That said, the actual number depends on:
- Your daily energy usage
- Panel efficiency
- Roof size, orientation, and shading
Your installer should use satellite imagery and site visits to give you a customized proposal — not just estimates.
How Many kW of Solar Do I Need?
This depends on your energy consumption. A typical Indian home may use 2 to 5 kW, but it varies based on:
- Appliance usage
- Family size
- Air conditioning or water heater use
- Grid electricity availability
Ask the solar company to conduct a load analysis based on your past 6–12 months of electricity bills. A genuine provider will tailor your system to match your needs, not oversell.
7 Questions About the Installer
When you’re evaluating a solar installer, ask:
- Are you licensed for solar work in this region?
- How many installations have you completed?
- Can I see photos or reviews from past clients?
- Who will be managing the project?
- Do you handle structural checks or roofing issues?
- What support do you provide after installation?
- How do you handle service calls or warranty claims?
A reliable installer will answer confidently and transparently — no hesitation.
7 Questions About Solar Equipment
Don’t forget to focus on the actual products going on your roof:
- What brand of solar panels do you use?
- Are they Tier 1 or BIS-approved panels?
- What is the efficiency rating of these panels?
- Do the inverters come with monitoring systems?
- What’s the warranty on panels and inverters?
- Do you offer battery backup or hybrid systems?
- How do you compare this equipment with others in the market?
Quality hardware ensures your system works efficiently for 25 years or more.
Questions On Installation Process
Understanding the installation process helps set realistic expectations. Ask your provider:
- How long will the complete installation take?
- Will I need to make changes to my roof or structure?
- Do you handle the grid-connection process?
- Is net metering supported in my area and included in your services?
- What approvals or permissions will I need, and do you help with them?
A trustworthy company will walk you through every step, from paperwork to switch-on.
How to Spot a Solar Scam
Unfortunately, not every company plays fair. Watch out for these red flags:
- Unrealistic promises like “zero electricity bills guaranteed”
- Pushy sales tactics or “limited time offers”
- No documentation or vague contracts
- Unregistered vendors with no online presence or business listings
- Quotes with no site visits or proper analysis
Always verify certifications, compare quotes, and check reviews before signing anything. Choosing trusted solar panel distributors in Coimbatore with proven experience ensures peace of mind and long-term savings.
