I noticed a recent question (How can I connect mismatched solar panels in parallel?) with three tags relating to solar power/photovoltaics. Each of these is an existing tag:
- solar-panel has 6 questions
- solar has 4 questions
- photovoltaic-cells has 5 questions (4 of which are shared with solar-panel)
There don't appear to be any other such tags (e.g., "solar-power" or the like) currently in use. Only a few questions come up in a search of the site for "solar" that are not already tagged with at least one of the above, and for the most part they only mention solar power incidentally.
What should we do with these tags? I don't see much benefit from using all three (or any two) on the same question.
