Not good imo.
Consider the best would be Solar.XYZ
SolarIndustry is only registered in 19 ext. Best to focus on 50+ extensions registered.
Also Solar Industry does not make a good brand. Solar King, Solar Pros, Solar anything. It would be like a food company making their brand "Food Industry". It doesn't make sense.
Consider this too:
Only ONE public sale for ALL Solar keyword .XYZ domains:
SolarEnergy.xyz sold for $185
That means out of all the Solar keyword .XYZ you are a LONGshot to even make a sale.
Honestly, 2 word .coms are hard to sell. Other extensions even more so.
Single word .xyz is the way to go. Better to save up and buy something Great.
