SYSTEM DESIGN
Its
quite easy to design a system.
- Follow the adjacent chart and see what sized system you or your family
needs. In the NW, sizing should be slightly higher to compensate for
our overcast and inclement weather that we experience during half the year.
As with any solar system, the FAFCO systems will not perform well during these
winter conditions. However, during the occasional "sun breaks", or
whenever the solar sensor is 10oF warmer than the water temperature
sensor at the bottom of your water heater or storage tank, the system will
operate and add heat. It is always best to oversize the panel area when
in doubt. Contact us for advise.
- Face southerly direction. Thankfully the panel area is small
enough that finding a location that faces within 30o of South
is usually available. This is especially important in states like Oregon
that have tax credits and must comply to strict installation criteria to
qualify. Even the federal credits have similar criteria but less
enforced. IN any event, it is in your best interest to design the system
for best performance.
