This means they are a possible solution for backup power for a large home, a business or jobsite.  This type of generator can run for an extended period without stopping for maintenance and so are a good candidate for long term needs.

A sun room is a great example of a sunspace for passive solar heating.  With this type of construction technology you are converting sunlight to heat which is very efficient.

This is a relatively simple home improvement project that qualifies for Federal tax credits.

Florian is a manufacturer that specializes in passive solar technology. 

Here is how a typcial installation works: 

• A southern facing position of your sunroom is preferred, however, east or west facing will be able to take advantage of the sun rising/setting
• During the Fall/Winter/Spring seasons, the sun stays low in the sky allowing free heat into the vertical walls of your solar collector sunroom. The "Heat Repellent" series roof glazing traps the solar heat in the upper area of the room.
• A thru-the-wall fan placed high in the sunroom is added to the room design, along with a thermostat and seasonal shutoff switch
• The thermostat will automatically cycle the fan on when the sunroom temperature reaches about 75 degrees, delivering free heat to your home
• A separate sunroom zone heat source may also be installed with a lower temperature setting so you may also enjoy your sunroom addition on those cold winter nights
