Installing solar panels? Don’t overlook the paperwork – here’s everything you should receive

You have watched the scaffolding go up, heard the drills, seen the panels lifted into place — and now your home is finally generating its own clean electricity. It’s a brilliant feeling, isn’t it?

But before you settle into lower bills and sunnier days, there’s one last part of the journey that often gets overlooked, even though it matters just as much as the panels themselves:

The paperwork.

It might not feel exciting, but it’s the quiet hero of your installation. These documents prove your system is safe, compliant and ready for the long haul. And months or years from now, they’re the very things that will save you time, money and stress.

Before installation – knowing exactly what’s being installed

A good solar installation should never leave you guessing. Before anyone climbs a ladder, you should already feel clear and confident about what’s going on your roof.

Your installer should give you:

• A detailed quotation and system design
• Expected annual energy generation
• Information about your panels, inverter and battery (if included)
• Details of any DNO application (G98 or G99)
• Confirmation that the installation will meet MCS standards

This stage is about trust. It’s about knowing you’re making the right investment — not just hoping you are.

During installation – the work you don’t always see

While the visible work is happening on your roof, there’s a quieter layer of the job unfolding behind the scenes. Your installation team is carrying out electrical tests, safety checks and system verifications that you’ll never see — but you’ll absolutely rely on later.

These records become part of your installation file. You may not receive them immediately, but they’ll appear in your final handover pack.

After installation – your complete handover pack

Once everything has been tested, commissioned and switched on, you should receive a handover pack. Think of it as the service history of your solar system — the story of how it was built, tested and approved.

It’s something you might tuck away for now, but you’ll be grateful for it when you need it.

Compliance certificates

These are the documents you’re most likely to need in the future:

• • MCS Certificate for your solar PV installation
  • MCS Certificate for your battery storage system (if applicable)

Your installer should also be MCS certified, which is a key requirement for accessing export payments. You can check what MCS certification means here:
MCS Certified.

• Electrical Installation Certificate (EIC)
• Building Regulations Compliance Certificate (where required)
• DNO / National Grid confirmation, including your export MPAN number

Technical information.

Testing and commissioning records

These documents explain exactly how your system was put together:

• • Solar PV electrical schematic
  • Technical datasheets for your panels, inverter and battery
  • Test Certificates and serial numbers
  • Electrical testing results
  • Commissioning documentation
  • Performance verification records

These confirm that your system was operating safely and correctly on the day it was handed over. If you ever upgrade your system or need maintenance, these details become incredibly useful.

Operating your system

Even though modern solar systems are wonderfully low‑maintenance, you should still receive guidance on how everything works:

• Startup and Shutdown procedure
• Safety information
• Maintenance recommendations
• Manufacturer manuals

Warranties

Make sure you receive all warranty information covering both the equipment and the installation itself:

• Solar panels
• Inverter
• Battery storage (if installed)
• Installation workmanship

Why all this paperwork matters

When your system is running smoothly, it’s easy to forget about the documents tucked away in a drawer. But one day whether you are applying for SEG payments, selling your home or diagnosing a fault  then you will be glad you kept them safe.

You may need them to:

• Register for Smart Export Guarantee (SEG) payments
• Notify your home insurer
• Sell your property
• Upgrade your system
• Make a warranty claim
• Diagnose a technical issue

Your paperwork is proof. It’s protection. It’s peace of mind.

More than paperwork – it’s about the people behind it

At Solar Save Renewables, we have always believed that installing solar panels is only half the job. The real test of a good installer is what happens after the panels are up.

That is why every customer receives a clear, organised handover pack. And if you have questions weeks, months or even years later, we’re still here. No call centres. No ticket numbers. Just real people who know your system and want to help.

Our customers value:

• A local team you can actually talk to
• Honest, personalised advice
• Ongoing aftercare and technical support
• Clear communication from start to finish
• A company that is proud of its work

Choosing a solar installer isn’t just about comparing quotes. It’s about choosing people you’ll still feel comfortable calling in five or ten years’ time.

Because when you choose local, you’re not just investing in solar panels, you’re investing in peace of mind.

A solar installation should leave you with more than a working system. It should leave you feeling confident, informed and supported.

The right paperwork gives you certainty. The right installer gives you trust. And together, they make your solar journey something you can feel genuinely proud of.

Anyone can install solar panels. The best installers make sure you understand them.

At Solar Save Renewables, we believe the job isn’t finished when the panels start generating electricity. It’s finished when you know exactly how your system works, have every document safely in your hands, and feel confident that if you ever have a question, you’ll speak to someone who knows both your system and your name.

That is why we don’t just install solar. We build long-term relationships with homeowners across Wales. Because solar is an investment for the next 25 years—and we believe your installer should be there for the journey too.
