How do different solar technologies effect the environment?
During operation, PV and solar thermal technologies produce no air pollution, little or no noise, and require no transportable fuels. One environmental worry with solar technologies is the lead-acid batteries that are used with some systems. This is a concern especially in developing countries where proper disposal and recycling is not always available. The impact of these lead batteries is lessening however as batteries become more recyclable, batteries of improved quality are produced and better quality solar systems that enhance battery lifetimes are created.
