It makes sense. Their only real opposition to solar power has been the fact that it's not a fossil fuel, and the fossil fuel industry had enough money to keep the republicans in their pocket. Now that solar companies have some money, they can afford to buy some Republicans.
Solar power fits the conservative mindset a lot better than wind (or honestly even coal). You probably aren't going to power your own house on wind or coal, but you absolutely could on solar. Solar works better collectively, but it's still pretty easy to set up a house as your own personal fiefdom. Once you have assured that you will never run out of power, you can start undermining collectivised energy infrastructure.
The hate on offshore wind i think is literally just rich people not wanting them in their sight.
