With electricity prices skyrocketing and sustainability becoming a necessity, going solar is one of the smartest investments you can make. But before you jump in, there’s one crucial decision that can make or break your solar journey: choosing the right installer.
With so many solar companies promising the best deals, how do you know who to trust?
At Gemini Solariss, we believe every homeowner and business deserves full transparency and top-quality service. That’s why we’ve put together this essential guide with the 15 most important questions to ask your solar installer — so you can make a confident, informed choice and protect your investment from the start.
1.Are You Accredited?
First things first: you need to know your installer is fully certified. Look out for important accreditations such as:
- MCS (Microgeneration Certification Scheme)
- Flexi-Orb (Flexible Energy Oversight Registration Body)
- NAPIT (National Association of Professional Inspectors and Testers)
- TrustMark
- HIES (Home Insulation and Energy Systems Quality Assured Contractors Scheme)
Accreditations like these prove that the installer meets industry standards, protecting you from poor workmanship and allowing you to access government-backed incentives like the Smart Export Guarantee.
Solaris is proud to be fully accredited, giving our customers complete peace of mind.
2. Can I Trust the Estimates?
While you are handed over with a quotation, knowing whether the energy savings and cost estimates are appropriate is important.
Ask if the estimates have been validated by the Energy Performance Validation Scheme (EPVS). EPVS ensures the figures you’re being shown are accurate and not inflated to make a quick sale.
At Gemini Solariss, transparency is non-negotiable. We validate our performance predictions so that you can make informed decisions, not risky ones. We sit with you and discuss everything before
3. What Type of Solar Panels Do You Use?
Not all solar panels are created equal!
You’ll want to know:
- Are the panels monocrystalline (higher efficiency) or polycrystalline (lower cost)?
- What is their power rating (e.g., 430W vs. 330W)?
- What is their efficiency (ideally between 18–23%)?
- How long is the warranty (aim for at least 25 years)?
At Gemini Solaris, a top solar panel dealer in Tirunelveli, we only install premium solar panels with high-efficiency ratings and solid warranties, ensuring maximum output and longevity for your system.
4. What Battery Storage Solutions Do You Offer?
If you’re investing in battery storage, you should also ask:
- What brand and model is the battery?
- What is its storage capacity (in kWh)?
- Is it a lithium-ion (preferred) or lead-acid battery?
- What’s the warranty (ideally 10 years or more)?
Solaris offers high-quality lithium-ion battery options with industry-leading warranties designed to store more power and last longer.
5. How Long Will the Installation Take?
Find out:
- The expected waiting time before installation begins
- How long the actual installation process will take
We provide clear timelines upfront — and we stick to them. Most residential installations are completed within one to two days, with scaffolding setup included.
6. Do You Provide Insurance?
Solar panel systems are a big investment, and they should be protected.
Make sure the installer offers the following:
- Insurance covering fire, theft, and storm damage
- An Insurance Backed Guarantee (IBG), which is required by Flexi-Orb and MCS members
At Gemini Solariss, every installation we deliver is protected with comprehensive insurance and backed by solid guarantees.
7. What About Maintenance and Aftercare?
Solar systems are relatively low maintenance, but things can still go wrong over time.
Ask whether the installer offers:
- Regular maintenance services
- Monitoring support
- Quick repairs, if needed
Gemini Solariss provides complete aftercare, ensuring your solar system operates efficiently for decades. As a leading solar panel distributor in Tirunelveli, our customers also access monitoring tools for real-time performance insights.
8. How Experienced Is Your Company?
The solar industry is booming — and unfortunately, not every new installer is reliable.
Ask how long the company has been in business. Ideally, choose a provider with at least 3+ years of experience.
With years of successful installations across residential and commercial projects, Solaris is a name you can trust.
9. What Are Your Certifications and Industry Memberships?
Aside from MCS and Flexi-Orb, it’s worth asking if your installer has:
- NABCEP certification (essential in international markets)
- B Corp certification (for ethical, sustainable business practices)
10. What Incentives Are Available?
A good installer should be able to guide you through the maze of federal, state, and local solar incentives.
From federal tax credits to regional rebates, incentives can slash your installation cost by up to 60%!
At Solaris, we help you maximize your savings by tapping into every incentive you’re eligible for.
11. Is Your Equipment Ethically Sourced?
It’s important to know where your solar equipment comes from.
Solar panel installer in Tiruneveli by Gemini Solariss: We prioritize sourcing ethically made and high-quality components, making sure that our panels are durable, responsibly produced, and built for long-term performance.
12. Will I Need a New Roof?
If your roof has less than 10–15 years of life left, replacing it before going solar is smart. Solaris’ team will assess your roof’s condition during our initial site survey and advise you honestly if any upgrades are needed.
13. Who Will Perform the Installation?
Some companies handle only sales and outsource the installation to third parties. This can lead to poor communication and quality issues. At Gemini Solariss, we handle your project end-to-end—no third parties, no compromises.
14. What Is the Total Cost per Watt?
Don’t just look at the total project cost. Ask for the cost per watt, which gives you a more precise comparison across different installers.
We offer competitive pricing without sacrificing quality and will break down all costs transparently.
15. Are There Fees Associated with Financing?
Solar financing can be a great option but always ask:
- Who provides the loan?
- Are there hidden fees?
- What happens if you default?
We offer clear, fair financing options with no nasty surprises.
Choosing a solar panel installer in Tirunelveli is a big decision, but by asking the right questions, you’ll protect your investment and ensure a smooth, rewarding solar journey. When you choose Gemini Solariss, you’re not just getting solar panels. You’re getting a trusted partner committed to quality, transparency, and customer success.
