althouGh they are most common in remote locations without utility grid service, off-

from the grid to provide all of a household’s electricity. That means no electric bills
& no blackouts—at least none caused by grid failures. People choose to live off-grid

    •Idling your vehicle pollutes, wastes fuel, and
             contributes to climate change.
 • Idling a car more than 10 seconds uses MORE
       fuel than turning the engine off and on.
     • Warm up by driving slowly, warming the
      transmission, wheel bearings, and engine.
 • Idling produces more than twice the normal harmful
  emissions and damages your engine by depositing
         residues from incomplete combustion.
• When you are Idling, your Fuel economy is ZERO.

It is usually acceptable to mount the collectors flush on a pitched
roof close to the optimal orientation as possible in order to reduce installed cost and improve
aesthetics. Resource maps and tables of solar resource information throughout the U.S. are post-
ed at the Solar Radiation Resource Information Center(SRIC).
2. Protect against freezing. Damage can be caused if water freezes in the collector flow pas-
sages or connecting piping. There are several strategies for prevention of freeze damage. The
most common is to circulate a solution of propylene glycol (never use toxic ethylene glycol)                                               
and water in the collector loop of an indirect system. Another strategy is to drain the water
from the collector back into a small drain-back tank. This drain-back configuration has the
                                                                                                                                       
added advantage of protecting the system from excessive temperatures if hot water con-
sumption is reduced due to seasonal use patterns, remodeling, or vacations. Where freezing
is uncommon, a controller function that simply circulates water in the collector loop when
temperatures approach freezing in conjunction with freeze protection values may be ade-
quate.
3. Provide a tempering valve and bypass capability The tempering valve is very important to
assure consistent temperature water is delivered at the taps. Bypass piping and valves allow the
conventional system to provide hot water if the solar heating system is down for any reason.                                                              
