Solar panels can be divided into 2 main types:
Polycrystalline and Monocrystalline solar panels
Polycrystalline solar panels make better use of scattered light while monocrystalline solar panels make better use of direct light.
- makes better use of scattered light
- simpler manufacturing technology
- cheaper panels
- lower size / power ratio
- makes better use of direct light
- more expensive manufacturing technology
- more expensive panels
- higher size / power ratio
Their annual production difference is not significant in our climate, but the size / performance ratio of monocrystalline panels is more favourable. In practice, this means that while 1.7m x 1m polycrystalline panels are roughly 300w, panels of the same manufacturer can have up to ~ 340w for a monocrystalline panel of similar size.
