“Which solar panels should I choose?” It’s the first question most homeowners ask. And honestly? Most installers give you the same tired answer: “Monocrystalline are the best.”
But here’s what 15 years of installing solar systems across the UK has taught me: there’s no such thing as “the best” panel. There’s only the right panel for your specific situation.
Let me walk you through the four main types and when each one actually makes sense.
Monocrystalline: The “Premium” Option
These are the panels everyone talks about. Cut from single silicon crystals, they’re efficient and sleek looking. Perfect if you’ve got limited roof space and want maximum power output.
But here’s what most installers won’t tell you: if you’ve got plenty of roof space, paying extra for monocrystalline efficiency might be money wasted. Sometimes more polycrystalline panels give you better value.
Polycrystalline: The Reliable Workhorse
Made from multiple silicon crystals, these panels are slightly less efficient but significantly more cost-effective. They’re like the reliable family car of solar panels.
In the UK’s variable weather, the efficiency difference between mono and poly often matters less than installers claim. What matters more? Getting a system that fits your budget and roof space properly.
Thin-Film: The Flexible Solution
These aren’t rigid panels – they’re flexible sheets of photovoltaic material. Most installers dismiss them, but they have their place.
Got a curved roof? Unusual surface? Weight restrictions? Thin-film panels can work where traditional panels can’t. They’re also better in partial shading conditions, which is common in UK residential areas.
Bifacial: The Double-Sided Performer
Here’s the technology most installers don’t even mention: bifacial panels generate power from both sides. They capture direct sunlight from the front and reflected light from the back.
In the right conditions, particularly ground-mounted systems or installations over light-coloured roofs – bifacial panels can produce 10-30% more energy than traditional panels. But they need proper installation to work effectively.
So Which Type is Right for You?
This is where proper consultation matters. We don’t just recommend panels based on what’s popular or what gives us the best margin. We look at:
- Your available roof space and orientation
- Your budget and payback expectations
- Your roof material and structure
- Surrounding buildings and shading
- Your long-term energy plans
The Real Question Isn’t “Which is Best?”
The real question is: “Which combination of panel type, system size and installation approach give you the best return on your specific property?”
That’s not something you can answer with a quick phone call or online calculator. It requires proper assessment by qualified engineers who understand both the technology and your individual circumstances.
Why This Matters More Than You Think
Choose the wrong panel type and you might end up with:
- Overpaying for efficiency you don’t need
- Underpowered systems that don’t meet your needs
- Panels that don’t perform well in your specific conditions
- Systems that could have been better designed for your roof
After 15 years of fixing other installers’ mistakes, I can tell you: the “best” panel is the one that’s properly matched to your home by someone who knows what they’re doing.
