What to Ask Before Choosing a Solar Installer – Expert Tips from Solar Installers in Hertfordshire
Investing in solar panels is a big decision — one that can reduce your energy bills, increase your home’s value, and lower your carbon footprint.
But before you sign any contracts, it’s essential to make sure you’re working with the right solar installation company.
At Belectrix (About Page Here), your trusted solar installers in Hertfordshire, we often meet customers who wish they had known what to ask before starting their solar journey. Here’s a quick guide to the most important questions you should ask any potential installer.
1. Are You MCS Certified?
Always start with certification.
An MCS (Microgeneration Certification Scheme) accreditation means your installer meets strict UK standards for safety, design, and installation quality.
Only MCS-certified installations qualify for most energy export or smart tariff schemes — so don’t skip this step.
👉 Belectrix is fully MCS and NICEIC registered, giving you complete peace of mind that your system meets all industry standards.
To verify an installer’s accreditation, visit the MCS Certified Installer Database and search for certified companies in your area.
2. What Warranties Do You Provide?
Ask for details on both product and workmanship warranties.
A good solar installer should offer:
-
Panel warranty: typically 25 years on performance.
-
Inverter warranty: usually 5–10 years (extendable).
-
Workmanship warranty: covers installation quality and electrical work.
Make sure you know who to contact if something goes wrong — the manufacturer or the installer.
3. How Do You Design the System for My Home?
Avoid “one-size-fits-all” solutions.
A professional solar installer should:
-
Conduct a site survey (roof pitch, direction, shading).
-
Review your electricity usage and tariff.
-
Offer a tailored system design with performance estimates.
At Belectrix, we design every system individually using specialist software to ensure maximum generation and return on investment.
4. Do You Offer Battery Storage or EV Charging Options?
Solar isn’t just about panels anymore.
Ask your installer if they provide battery storage or EV charging integration, so you can store excess energy or charge your electric vehicle directly from your solar system.
We provide fully integrated systems – including solar PV, battery storage, and EV charging modules, ensuring all components work seamlessly together.
5. Can You Show Me Previous Work or Reviews?
A reputable installer should be able to show examples of past projects and customer feedback.
Check for:
-
Online reviews
-
Case studies with real system performance data
-
Photos of completed installations
Seeing real work builds trust — and helps you understand the installer’s experience with projects similar to yours.
6. What Aftercare or Maintenance Support Is Included?
Solar systems are low-maintenance, but not maintenance-free.
Ask your installer if they offer annual servicing, system health checks, and firmware updates to keep your system running efficiently.

7. How Do I Monitor My System’s Performance?
A good installer will provide access to a monitoring app or portal where you can track energy production and usage in real time.
At Belectrix, we set up your monitoring system and show you how to read and understand your solar data.
8. What Happens If I Move House?
Ask your installer how your system might affect resale.
In most cases, a professionally installed and MCS-certified solar system adds value to your property and can be transferred to the new owner easily.
Your installer should provide documentation and certificates for your records.
