What is an MCS Certificate For Solar

If you’re looking into solar panels or a home battery system, you’ve probably seen the term MCS Certificate mentioned everywhere. But what actually is it — and why do you need one?

As an MCS-accredited installer, we issue an MCS Certificate with every solar PV installation we complete at Solent Renewables. Here’s a clear breakdown of what it means and why it matters.

What Is an MCS Certificate?

An MCS Certificate is an official document that confirms your solar PV system was:

• Designed correctly
• Installed safely
• Commissioned to strict UK standards
• Fitted by an accredited installer

“MCS” stands for the Microgeneration Certification Scheme, the UK’s quality assurance scheme for renewables.

Why Is an MCS Certificate Important?

1. It protects your warranties

Most solar manufacturers require installation by an MCS-certified company to maintain product warranties.

2. It allows you to access SEG export payments

To get paid for exporting surplus electricity (the Smart Export Guarantee), energy suppliers require an MCS Certificate.

More about SEG requirements here:

3. It guarantees safety and compliance

Your certificate confirms the system complies with essential standards such as:

• BS 7671
• MCS PV Installation Standard
• IET Code of Practice

4. It’s valuable when selling your home

Solicitors often ask for proof of compliance for solar installations.
The MCS Certificate is your official documentation.

What’s Included in an MCS Certificate?

Your certificate includes key details such as:

• Installer details (e.g., Solent Renewables Ltd – MCS accredited)
• System size (kWp)
• Panel, inverter & battery models
• Roof pitch and orientation
• Estimated annual generation (SAP)
• Commissioning date
• MCS registration number

You’ll also receive a full Handover Pack, including:

• DNO approval
• Electrical test certificates
• Commissioning sheets
• Warranty documents
• System schematics / SLD

Who Issues the MCS Certificate?

Only an MCS-accredited installer can issue and register the certificate.

At Solent Renewables, we:

1. Finalise system commissioning
2. Register your installation with MCS
3. Provide you with the official certificate within a few days

Do You Need an MCS Certificate for Battery-Only Installations?

If you want to access export payments or ensure warranty protection, yes — it’s highly recommended.
MCS accreditation ensures:

• Correct battery sizing
• Safe installation location
• Fire-safety compliance
• Long-term support and traceability

How Long Does It Take to Receive the Certificate?

Most customers receive their certificate within 2–7 days of commissioning.

If you need it urgently (e.g., for SEG approval), we can prioritise the registration.

Final Thoughts

An MCS Certificate isn’t just a piece of paper — it’s essential for safety, performance, warranty protection, and accessing payments for exported electricity.

Every installation from Solent Renewables comes fully certified with all documentation neatly provided in your handover pack.
