Solar panels
- electricity generation
Main features
- generates electricity in daytime. Cloudy weather, shadows, direction (compass point) and angle of panels will effect to the amount of generation.
- generates more electricity in cold weather than in warm weather
- if electricity is not used simultaneously with electricity generation, the system needs a battery pack for storage.
Additional features
- the electricity needed for 24 hours should be generated in daytime and the night time need is stored to a battery pack
- efficiency of commercial solar panels is around 15-17% (status in 2018) of the solar radiation
- life cycle of a solar panel is around 25-30 years, life cycle of batteries is shorter
