Solar panels also have an issue that come with it covering the earth with more black surface which is negating the point of what the ice was doing to cool the earth before it melted. Ocean water is black and solar panels are black. This is known as albedo effect.

then you have the issue of helping people. Sure, helping people who have NO ACCESS TO WATER this should definitely be an option.

But offering it to people whom already have tap water and access to water as a secondary ‘cheaper’ option is not so altruistic particularly if we don’t consider the impact as the aforementioned non reflective surface that is a much bigger impact on global warming. Hence that solar panels aren’t an all-source solution for the overall issues.
