Investing in solar panels is one of the smartest decisions you can make for your home, but only if it’s done properly.
With so many new installers entering the renewables market, it’s easy to get dazzled by prices and promises. Before you sign anything, it’s worth knowing what really matters – the checks that protect your investment, your roof, and your long-term savings.
Here’s what every homeowner should know before buying solar.
☀️ 1. Always Check for MCS Accreditation
This is the single most important thing to confirm.
The Microgeneration Certification Scheme (MCS) is the industry standard for renewable energy installers in the UK. It guarantees that both your panels and the installation meet strict quality, safety and performance criteria.
If your installer isn’t MCS-accredited:
- Your system won’t qualify for the Smart Export Guarantee (SEG) payments.
- Your installation won’t be officially recognised by energy suppliers.
- You may struggle with warranty or insurance claims later on.
At Novus Energy, all our installations are fully MCS-certified and insurance-backed, giving you complete peace of mind that your system meets the highest UK standards.
🧾 2. Compare Warranties, Product and Workmanship
Not all warranties are equal. Some companies offer panel warranties only, while others protect the full system. You deserve both.
Before you commit, ask these questions:
- How long is the performance warranty on the panels? (It should be around 25 years.)
- What’s the product warranty on the inverter and battery? (Typically 10 years.)
- Is there a workmanship warranty that covers installation quality?
At Novus Energy, we provide all three, including a 10-year insurance-backed workmanship guarantee, so you’re covered from day one through to year ten and beyond.
📄 3. Ask About DNO Approval
This is one of the most overlooked but crucial parts of going solar.
Before your system can be connected to the grid, it must be approved by your Distribution Network Operator (DNO), the organisation that manages your local electricity network.
A professional installer should:
- Submit the DNO application on your behalf
- Handle all compliance paperwork
- Provide confirmation once your system is approved and live
If your installer doesn’t mention DNO approval, that’s a major red flag.
With Novus, DNO approval is always included, so you can relax knowing your system is fully compliant and ready to export.
🏗️ 4. Make Sure Your Quote Includes Scaffolding & Aftercare
A low-cost quote can look tempting, until the hidden extras appear.
Always check whether your solar quote includes:
- ✅ Scaffolding (often adds £500+ if excluded)
- ✅ System testing and commissioning
- ✅ Monitoring setup so you can track performance
- ✅ Aftercare support in case you ever need help
Transparent pricing matters. At Novus Energy, scaffolding, certification, and aftercare are always part of your quote. No hidden costs, no corner-cutting, just professional installations done properly.
💡 5. Buy Once. Buy Right.
Solar is a long-term investment, not a short-term saving exercise.
Choosing a trusted, accredited installer means your system will perform efficiently for decades to come, protecting your roof and maximising your return.
At Novus Energy, we believe in:
✅ Honest advice, not sales pressure
✅ Premium equipment from trusted brands
✅ Certified workmanship backed by real warranties
✅ Exceptional aftercare and monitoring support
When you buy solar, make sure you’re investing in quality, because doing it right the first time is always cheaper than doing it twice.
