You recently (November 1) responded to a problem about condensation on the outside of double-glazed windows; I have a similar problem, except mine is on the inside. I have bought a flat where double glazing was installed about four years ago. My flat is heated and there is a radiator under the window in the bedroom.
Most homeowners are paying $3 to $4 per watt to have solar panels installed in Los Angeles, with the average cost of $3.57 per watt. Using 5-kilowatt hour translates to an average gross amount of $12,500 after the Federal ITC discount.
