SCOPE OF WORK: Solar water heating system Improvement/RetrofitThe scope of work is to verity that the solar water heating system specified in this document meets the requirements set forth in Florida Building Code Residential, 6th edition (2017), FSEC standard 104-10 and Florida Statutes 377.705.
APPLICABLE CODES, STANDARDS, and CERTIFICATIONS
– 2017 (6th edition ) Florida Building Code. Specifically
chapter 14, solar systems
– ASCE 7-10 Minimum Design Loads for Buildings and Other Structures
– NSF/ANSI 61 relating to lead standards in Potable water systems
– Florida Statute Section 377.705 requiring FSEC or approved
certifications
– FSEC 104-10 “Florida Standards for Design and Installation of
Solar Thermal Systems”
NOTES
1. Drawings, calculations, tables developed requiring a PE seal and
signature
2. Support documents, cut sheets, tables, reprints from publications
such as ASCE 7-10, and shop drawings that do not require a PE seal
and signature
NOTES:
1. Wind load calculations based on 2017 FBC 6th Ed Table R301.2(2) Roof Pressures, which is a modified components and cladding adjusted to .6 factor for ASD.
2. Wind force estimates are collector area dependent. The table provided on p2 was developed using the smaller area of the AE-21 collector giving slightly higher pressures for the larger panels. This complies with FBC to use the area of 1 module or collector for wind pressure calculations.
3. The design of this installation is based on requirements of the 2017 (6th edition) Florida Building Code (FBC) and referencing equations set forth by ASCE standard ASCE/SEI 7-10 and testing of the solar collector in accordance with TAS 202-94/ASTM E330. All aluminum structural members to be 6061-T6 with all structural steel to be low carbon galvanized steel and all hardware to be Type 304 Stainless Steel.
4. The Solar Collectors installed per these drawings are for the Alternate Energy Technologies (AET) listings; AE-21, AE-32 and AE-40, with a maximum uplift of 51 psf for 4 mounting points and up to 68 psf (AE-40 horizontally mounted) when using 6 mounting points.
5. Collector(s) must be mounted using AET mounting hardware per the manufacturer’s instrucions in order to obtain the listed wind rating.
6. Wet collector load is under 5 psf total for all models.
7. When flush mounted to the roof with AET mounting hardware, the air gap between the collector and the roof is between 2” to 10” thus eliminating the collector from being considered as part of the building envelope.
8. In all cases, the installation contractor must comply with any local AHJ requirements.
9. Piping to be Type L copper Hard or annealed, 1/2” dia.
Where O=open direct system first numbers are tank size, second numbers are array area. All are AC active pumped using a different controller with sensors.

Collector consists of a copper absorber, closed cell insulation, low iron glass and 6061-T6 aluminum extruded side wall. Collector has been tested to 102 psf. American Water heater tank or approved equivalent in sizes of 50, 66, 80, and 120 gallon capacities. Tank is a solar/electric combination that uses a single 4500 watt element during periods of inclement weather to ensure an adequate supply of hot water.

HOW TO USE THIS TABLE AND FIGURE:
1. Determine wind zones on roof from figure. “a” is 4 ft in all cases.
2. Obtain the wind speed from the local authority having jurisdiction.
3. Note roof pitch and mean elevation (height) of the roof and round up. Example: mean roof elevation is 16 ft, use 30 ft.
4. Pick the table that fits the exposure and mean roof height. Example: Category C exposure - site conditions with some flat areas and 15 ft means the mean roof height is no taller than 15 ft. Mean roof height is the average of the ridge and eve heights.
5. Locate the column for the wind speed and circle the down force and uplift pressures for the three roof pressure zones.
6. Uplift pressures up to and including 51 psf can use standard mounting hardware with 4 mounts per panel. 4x10 can only be mounted on the 10 ft long sides due to panel deflection. For panels mounting in roof zones 52 psf to 68 psf, high wind mounts for the 4x10 panel, 6 mount attachments must be used.

NOTES:
1. Pressures shown are applied normal to the surface, for exposure B, at h=30 ft (9.1m). Adjust to other conditions using Equation 30.5-1.
2. Plus and minus signs signify pressures acting toward and away from the surfaces, respectively.
h: Mean roof height, in feet (meters), except that eave height shall be used for roof angles <10°.
Ø: Angle of plane of roof from horizontal in degrees.

2017 FBC specific code references:
M2301.1 General - covers general requirements of solar water heating systems for
potable water.
607.5 Piping on the cold and hot water connections to the water heater must be insulated
with 1/2” wall thickness Elastomeric tube insulation
M2301.2 Complies with the design installation requirements set by the manufacturer
M2301.2.6 No expansion tank required for the solar system as it is an open system
whereby potable water is circulated through the collector. Water expansion is factored
into the hot water system of the dwelling unless CPVC pipe is used. In this case, a 2-
gallon expansion tank must be installed on the cold water inlet to the tank or as may be
required by local AHJ’s.
M2301.4 Prohibited heat transfer fuids does not apply to these systems which use
potable water in the collector loop.
M2902.5.5.3 Solar water heating system complies with requirements set forth covering
direct system where potable water comes in contact with system components.
P2801.6 and P2801.6.1 references water heater drain pan size and drains. Drain not
required if not previously installed. Drain pan supplied by others, must comply with this
section.
P2802 is a new code relating to solar water heating mixing and isolation valves.
P2802.1 relates to water temperature control and requires a thermostatic mixing value.
P2802.1 relates to isolation valves on the cold water feed to the water heater.
P504.1 for antisiphon is met by use of a small hole in the cold water inlet pipe as listed in
code.
