Origin from Latin
The word 'solar' comes from the Latin word 'sol,' which means 'Sonne' (sun). So anything that is 'solar' has directly to do with the sun or its energy.
EXAMPLE
Die Raumsonde nutzt solare Strahlung für ihre Messungen.
The space probe uses solar radiation for its measurements.
Typical collocations
'Solar' is used almost exclusively in the context of energy and technology. Common combinations are 'solare Energie' (solar energy), 'solare Wärme' (solar heat), and 'solarer Strom' (solar electricity).
EXAMPLE
Viele Haushalte heizen ihr Wasser mit solarer Energie.

Forming compounds
Very often, 'solar' is not used as an independent adjective, but as the first part of a compound noun: 'Solar-'. Examples are 'Solaranlage' (solar system/solar installation), 'Solarzelle' (solar cell), 'Solarstrom' (solar power), or 'Solarpark' (solar farm).

solar vs sonnig
sunny
'solar' and 'sonnig' both have to do with the sun, but they are used in different situations. 'solar' sounds more technical and describes things that work with solar energy or relate to the sun. 'sonnig' mainly describes weather, places, or days with lots of sunshine. Learners may confuse the words because both come from the topic of the sun. Remember: a system or device can be 'solar', while a day or a balcony is 'sonnig'.
