How to Choose the Right Solar PV Installer

How to Choose the Right Solar PV Installer

At GB NRG, we know that choosing a solar PV installer can feel overwhelming—especially when you’re trying to make the best long-term decision for your business. With energy costs on the rise and sustainability higher on the agenda than ever, investing in commercial solar panels is a smart move. But picking the right installer is just as important as choosing solar in the first place.

In this blog, we’ll guide you through what to look for in a solar PV installer—so you can feel confident, save money, and make a real difference.

What Does a Solar PV Installer Do?

A solar PV installer designs, supplies, and installs solar photovoltaic (PV) systems that generate electricity from sunlight. For commercial projects, they also handle everything from grid applications and planning to health and safety, performance monitoring, and maintenance.

At GB NRG, we manage the full process—from first survey to final connection—so our clients can focus on running their businesses.

Why Choosing the Right Solar PV Installer Matters

Installing solar PV is a long-term investment. A well-designed system can provide clean, low-cost energy for 25 years or more. But a poor-quality installation, rushed design, or unreliable contractor can lead to higher costs, downtime, and lower returns.

Choosing a professional, experienced installer is the difference between a solar system that quietly powers your business for decades—and one that becomes a constant headache.

6 Things to Look for in a Solar PV Installer

Here are the key signs of a trustworthy, capable installer:

1. Proven Experience with Commercial Projects

Installing solar panels on a commercial site is very different from a domestic job. You need a partner who understands business energy needs, roof structures, and compliance rules. Ask for case studies and examples from similar sectors.

At GB NRG, we’ve delivered commercial solar projects for factories, warehouses, schools, and retail chains across the UK.

2. Accreditations and Certifications

Always check for industry-recognised certifications. In the UK, look for:

  • MCS (Microgeneration Certification Scheme) – guarantees installation quality

  • RECC (Renewable Energy Consumer Code) – for customer protection

  • NICEIC or similar electrical accreditations

  • CHAS or SafeContractor – for health and safety compliance

These show your installer follows best practices and high standards.

3. Clear, Transparent Pricing

A good installer will give you a clear proposal that outlines:

  • System size and output

  • Equipment being used

  • Costs and payback time

  • Expected energy savings

  • Any available funding or incentives

Watch out for vague quotes or high-pressure sales tactics. A reputable company will help you understand the figures, not hide them.

4. Tailored Design and Advice

Your business is unique—and so is your site. A reliable solar PV installer will take the time to understand your:

  • Energy usage patterns

  • Roof condition and orientation

  • Operational hours and future needs

At GB NRG, we design each system from scratch based on your goals, not a one-size-fits-all solution.

5. End-to-End Project Management

Look for an installer who offers full project management. That means they:

  • Handle DNO/grid permissions

  • Carry out structural and electrical surveys

  • Manage installation and commissioning

  • Provide ongoing maintenance and monitoring

This approach reduces risk, saves time, and keeps things running smoothly.

6. Ongoing Support and Maintenance

Solar panels need very little upkeep—but when they do, it matters who’s on the other end of the phone. Choose an installer who offers performance monitoring, warranty management, and fast-response maintenance.

At GB NRG, we don’t just install and disappear—we’re here for the long run.

Questions to Ask Before You Sign a Solar PV Installer

To make sure you’re in safe hands, ask your potential solar PV installer:

  • How many commercial projects have you completed?

  • Are you MCS certified and RECC registered?

  • What’s included in the quote—are there hidden extras?

  • Who will manage the grid connection?

  • What happens if the system underperforms?

  • Can I speak to past clients?

The right installer won’t just give the right answers—they’ll make sure you understand them too.
