Why would we raise prices on ANY solar panels? That seems self-defeating to me. It doesn't really matter where they come from. Any solar panels are good solar panels.
To stimulate local production. But local producers just raised their prices. And, when the new import tax was announced it immediately resulted in shortages because companies kept solar panels in stock to sell them after they raised their prices. Sounds like some good lobbying to me.
I've been tracking prices for solar for the last couple of years, and I've only seen them go down. Pulled the trigger and purchased our own install because they went down yet again this year.
Google on "importheffing zonnepanelen" for the reports. I don't have solar panels, I just read the reports from time to time, your input is more valuable.
The excuse was that the Chinese were dumping and local solar industry in the US/EU needed protection. The likely actual reason was that fossil fuel companies demanded it and Obama/EU thought he/they could sell it to the public.
