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.
That translates to about $34,800 for a four-kilowatt system, the average size of a residential installation. To see real average cost data for solar projects installed near you, visit the Find a Contractor page on California Solar Statistics.he cost of a PV system depends on the system size, equipment options (panels and inverters), permitting costs, and labor costs. Prices vary depending on other factors as well, such as whether your home is new, where the system is installed on your premise, the PV manufacturer, and other factors.
