4 Types of Solar Panels & Which Is Right for You
Not sure which type of solar panel is best for your home? You’re not alone. With so many options on the market, it’s easy to feel overwhelmed.
As an experienced solar installer in Lancashire, PurelyPowered knows exactly what works best and can guide you through the choices with confidence.
Keep reading as we break down the pros and cons of the most common types of solar panels, so you can make an informed decision.
What are the main types of solar panels?
There are four main solar panel types commonly used in UK homes today: Monocrystalline panels, polycrystalline panels, thin-film panels and passivated emitter and rear cell (PERC) panels.
Monocrystalline panels
Monocrystalline panels are made from a single crystal of silicon, which gives them a solid black finish and the highest efficiency of all panel types. They’re one of the most widely used panels in the UK because they maximise output from limited roof space.
Pros:
- Very efficient at generating electricity
- Attractive black design that suits all property styles
- Long lifespan (often lasts 25 years or more)
Cons
- Higher installation cost
- Doesn’t perform well in extreme heat (not common issue in the UK)
- Manufacturing process produces more waste
Polycrystalline panels
Polycrystalline panels are made from multiple fragments of silicon melted together, which gives them an unusual blue, speckled appearance. They’re a more affordable alternative to monocrystalline and are a good option for homes with plenty of roof space.
Pros
- Lower installation cost
- Reliable performance and efficiency
- Long lifespan (usually between 20 and 25 years)
Cons
- Not as efficient as monocrystalline panels
- Not as aesthetically pleasing to some homeowners
- Doesn’t perform well in extreme heat (again, less of an issue in the UK)
Thin-film panels
Thin-film panels are made by layering photovoltaic materials onto a glass, metal or plastic surface. This creates lightweight and flexible panels that are manoeuvrable for flat or oddly-shaped roofs.
Pros
- Easy to install on awkward or flat surfaces
- Perform well in shaded conditions
- More affordable installation costs
Cons
- Not as efficient as monocrystalline or polycrystalline panels
- Shorter lifespan (typically between 10 and 15 years)
- More prone to performance degradation over time
Passivated emitter and rear cell (PERC) panels
PERC panels are an upgraded version of standard monocrystalline panels, with an added layer on the back that reflects unused light back into the cell. This makes them more efficient in low light and high heat conditions.
Pros
- Very high efficiency
- Perform better in low-light and high-heat conditions
- Offers a good balance of performance and value
Cons
- Slightly more expensive than standard solar panels
- Newer technology can be confusing for homeowners
- Prone to light and temperature degradation over time
