Common Mistakes to Avoid Before Installing Solar

Installing rooftop solar is one of the best decisions you can make for your home or commercial building — especially in a bright, sunny region like Chennai. But many people rush into the process without proper understanding, leading to poor performance, unexpected costs, or disappointing results.

To help you avoid these issues, here are the most common mistakes homeowners and businesses make before installing solar, and how you can avoid them.

1. Not Checking Roof Space and Shadow Properly

One of the biggest mistakes is assuming any terrace can support solar panels. In reality, shadows from nearby buildings, trees, water tanks, or AC units can reduce your solar output significantly.

What to do:

  • Ensure your roof has enough shadow-free space

  • Check sunlight availability during peak hours (10 AM – 3 PM)

  • Ask your installer for a proper shadow analysis. 

2. Focusing Only on Cheapest Price

Many homeowners choose the lowest quotation and regret it later. Cheap solar systems often use low-quality panels, weak mounting structures, and poor wiring — all of which affect long-term performance.

What to do: 
Choose a company that offers quality components and transparent installation practices.
A good solar system should last 20–25 years, so trust and reliability are more valuable than a “discount.”

3. Choosing the Wrong System Type (On-Grid vs Off-Grid vs Hybrid)

Another common mistake is selecting a system that doesn’t match your actual needs.

  • On-grid is best for most Chennai homes

  • Off-grid requires batteries and is only for areas with poor grid access

  • Hybrid is premium and offers both backup + grid savings

What to do:
Select a system based on:
✓ Your EB bill
✓ Your load usage
✓ Your area’s power stability

4. Ignoring the Importance of Inverter Quality

People often think panels are the only important part of the system. But your solar inverter is the heart of the installation — it converts solar energy into usable power.

Cheap or poor-quality inverters can cause efficiency loss, frequent shutdowns, and voltage issues.

Always invest in a trusted inverter brand.

5. No Clarity on Net Metering / EB Process

Many customers install solar without understanding how net metering works or how their EB bill will change.

What to do:
Ask your installer to clearly explain:

  • The metering mechanism applicable to you

  • How exported and imported units work

  • How your bill will be adjusted every month

Understanding this helps you set the right expectations.

6. Forgetting About Long-Term Service & Support

Solar is a long-term investment, and your installer should offer:

  • Regular checkups

  • Warranty support

  • Help with inverter issues

  • EB meter guidance

Choosing someone who disappears after installation is a major mistake.

7. Not Working With a Professional Solar Company

One of the biggest pitfalls is hiring unskilled technicians or part-time installers. Solar installation isn’t just about fixing panels — it involves electrical safety, structural planning, correct wiring, and compliance with EB regulations.

What to do:
Always choose a professional company with experience, proper documentation, and real customer support.

A reliable installer like Soltrix Energy ensures your system is designed correctly, installed safely, and built to deliver long-term performance and savings.

Do Solar Panels Work During Power Cuts?

Image
A common assumption many new solar users have is that once you install solar panels, your home will run even during power cuts.  While this feels logical, panels generate electricity from sunlight — the reality is more technical. Whether your solar system continues to supply power during an outage depends entirely on the type of solar system installed . Here’s a clear, informational breakdown of how solar behaves during power cuts and what you can expect from different system types. 1. Do Solar Panels Provide Power During an Outage? By themselves, solar panels do not keep your home running during a power cut.  Solar panels only generate DC electricity. To be usable, it must pass through an inverter, which must be safely connected to your home’s electrical system. The inverter plays the deciding role during a power outage. If it shuts down, power generation stops — even if sunlight is available. 2. Why On-Grid Solar Systems Shut Down During Power Cuts Most homes and commer...
