It's contentious, hence the 'citations needed' but Solar Minima result in increased Cosmic radiation and cloud cover.

That's logical,as with the weaker sun,the solar wind can't fight off the energetic particles which create a portion of the cloud condensation nuclei.
The caveat is,that it's a 'regional' effect.On a global scale,it's less significant.
The stratospheric ozone level be be reduced also,as it's a photo-chemically reactive molecule,allowing more UV to penetrate to ground level.
