Hello, I'm Rdp060707. I noticed that you made a change to an article, Photovoltaic thermal hybrid solar collector, but you didn't provide a source. I’ve removed it for now, but if you’d like to include a citation to a reliable source and re-add it, please do so! If you think I made a mistake, or if you have any questions, you can leave me a message on my talk page. Thanks. Rdp060707&#124;talk 04:30, 29 July 2021 (UTC)

Please do not add promotional material to Wikipedia, as you did to Photovoltaic thermal hybrid solar collector. While objective prose about beliefs, organisations, people, products or services is acceptable, Wikipedia is not a vehicle for soapboxing, advertising or promotion. Thank you.
