I am working on creating blueprints for my new home. My plan is to have both solar panels on the roof and a rainwater catchment system that directs water from the roof into some tanks in the basement. I expect to have a filter (not sure if it will be ceramic, fiber, etc.) somewhere between the tanks and the pump that will push the water into a bladder tank before it reaches the household pipes.
I know you can have solar panels on the roof, and I know you can harvest rainwater from the roof, but is there some health risk in harvesting rainwater that has fallen on solar panels (and the racks, cables, etc.)? Do I need to worry about any chemicals being leached into the water? If so, what would be the best way to filter them out? I plan to use this rainwater for drinking and cooking.
Note: I already plan to have a filter for things like bird droppings and other biomatter. My question is specifically about substances that could leach off the solar panels or any related hardware.

If you plan to use that collected water for drinking and cooking then you will need a proper filtration / treatment system... Ingesting diluted bird-droppings is not a good idea...
So, a simple filter may not be enough, you may well need UV treatment, but you should consult the authorities for the standards in your location you are legislated to meet and consult some just for your own health and others who may drink your water...
