What are Solar Panels made of?
'Monocrystalline' panels are the more expensive option (they'll cost you about 20% more than polycrystalline according to The Eco Experts), but are the most efficient for domestic households.
'Polycrystalline' solar panels are cheaper but they're about one-third less efficient than monocrystalline panels, meaning you'll need to have more panels on your roof to achieve the same power output.
