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.

The bulk of the price of going solar is now the âsoft costsâ (installation, permitting, etc.) rather than the solar panel cost. Again referencing the latest US Solar Market Insight report, the average installed cost of a residential solar panel system was $4.72/watt.However, prices vary tremendously by region.âCommon residential system prices ranged from less than $3.00/W to just above $7.00/W,â the Solar Energy Industries Association writes.y electric bill is about $140/month on average. So over 30 years solar would cost over $100,000 more than electricity from the grid (gas, coal, wind). Thatâs WITHOUT subsidies. All the articles include the subsidies but Iâm less interested in what will it cots ME as how much will it cost US.
