SITE SELECTION

The FAFCO solar panels require a mounting space 50 7/8" wide for each panel. When computing
the actual installed dimensions of the entire system, allow an extra 12" around the perimeter of the
bank to accommodate mounting apparatus, plumbing fittings and system

OPTIMUM ORIENTATION

The ideal location for the solar panels is a SOUTH-FACING PITCHED ROOF, near the pool. With
the panels facing true south, for the Northern Hemisphere, the optimum inclination is as follows:
1. For year-round heating: equal to latitude of installation.
2. For summer heating lattitude minus 10 to 15 degrees.
3. For winter heating: equal to latitude plus 10 to 15 degrees. The inclination must always exceed
10 degrees to ensure proper drainage.

PANEL REQUIREMENTS

See your dealer for sizing requirements.
A minimum of 65% to 100% of the pool's surface area in solar panels is the recommended "rule of
thumb" for sizing a swimming pool solar heating system. (Example: 800 sq. ft. pool needs 600 to
800 sq. ft. of panel area.)

PANEL MOUNTING SYSTEM

The FAFCO solar panels will provide years of trouble-free service if they are installed properly. All
of the clamps, couplers, and brackets necessary to join the solar panels together and to secure them in
place are included with the panel kits. The 1/4" lag screws recommended for use with mounting
brackets are not included because the proper length varies considerably with different types of
roofing. The FAFCO panel mounting system is designed specifically for the purposes of:
1. Accommodating the differential expansion and contraction associated with thermoplastic
materials under different temperature conditions.
Allowing flexibility in attaching the mounting brackets to most roof designs.
