You don't. Solar panels pollute in their manufacture, and they pollute in their disposal. As a life-cycle equation, it has been only over the last couple of years that the energy out has surpassed the energy in. It is government subsidies that make solar power cost-effective, and the fact that the really large solar farm have not yet approached the end of their useful lives.

Fossil Fuel plants create carbon dioxide in large amounts.
Wind Farms require acreage, which is in limited supply, but otherwise are comparatively cheap, effective and very long-lasting. Life-cycle cost-per-watt is far and away the cheapest of the lot.
Pick your poison. In terms of generating large amounts of unusable waste that cannot be recycled using present technology, Solar is the winner by a massive margin. It just hasn't gotten there yet.
Thank you, Your Honor!
Energy must also be reserved to repair and build the power-generation
facilities, be it solar panels or wind farms. All these facilities need
factories to produce, and factories themselves need energy.
I am wondering how all those big solar-panel farms process dead panels
without polluting their underground water ...
