What are the best solar panels?

Types of solar panel

• Polycrystalline panels are recognisable by their blue cells. Most have a plain aluminium frame and show white lines between the cells. They are often used on flat roofs, on shed roofs or in industry, where the look of the panels matters less.
• A monocrystalline panel has black cells. Combined with a black backsheet and a black frame we often use it where appearance matters. Monocrystalline panels are also rated slightly higher, which gives a slightly better yield.
• Thin-film panels are used where there is less direct sunlight, on roofs facing east or west for instance, because they turn indirect light into usable energy rather well.
