A. Condensation is not caused by double glazing (although new windows can sometimes make condensation problems worse, by cutting out draughts). Treatment for condensation is ventilation (to vent moisture-bearing air to the outside) and heating (to raise surfaces above dew point temperature).
A typical residential solar PV panel system in the U.S. costs $3.60/watt after installation, and the solar panels typically save the customer over $20,000 (net) over the course of 20 years.
