ROOF TRUSS CONSIDERATIONS Information Used In Analysis Roof Structure Standard Roof Sizes Tiles Factor of Safety Used No attic necessary Solar Panels Most efficient between 30-40° Each weighs around 80 lbs Could have up to 4 solar panels Each solar panel has a surface area of 4ft x 6ft Environment.2” of snow fall is the maximum ever recorded Winds could reach up to 206 mph (F3 tornado) Montgomery County has had 15 tornadoes since 1956

ROOF TRUSS LIMITS Beam Forces Maximum bending stress of material is 1650 lbs/ft² Maximum compressive stress is 1700 lbs/ft² Forces on trusses Flat Plate Collectors F=3.33lbs/ft² Forces in the negative y-direction Plywood F= lbs/ft² Force in the negative y-direction Shingles F=.304 lbs/ft² Force in the negative y-direction Wind F=.00256V² F=102.4 lbs/ft² Force in the x-direction

ROOF TRUSS DATA COLLECTION Factor of Safety (FOS) turns out to be 4.7 Beam Loading(2”x12”) Compressive loading failure is lbs Bending moment failure is lbs-inches Worst Case Scenario Calculations Compressive load is lbs Bending moment is lbs-inches

SOLAR WATER HEATING SYSTEMS Hydronic System Analysis Closed loop – Active system Potable water routed to storage tank Working Fluid circulates through collectors Potable water is heated through heat exchanger System requires auxiliary components like expansion tank, valves, etc.

BASIC ILLUSTRATION

MAJOR COMPONENTS ANALYZED analysis & selection of suitable pump selection of appropriate heat exchanger selection of main water storage tank. primary plumbing components – pipes For Each: options, benefits and costs analyzed

HYDRONIC SYSTEM PUMP ANLAYSIS How the analysis was carried out : 1. Design analysis was based on Architectural & Solar Thermal systems & options were considered 2. Architectural: basement & overall house dimensions 3. Solar Thermal: two possible options of Flat Plate Collectors with varying flow rates, dimensions and pressure losses. 4. Result of Total System Head Loss : No. of FPC’s Flow Rate (GPM ) Pressur e drop (Psi) Cumulative Head Loss (Ft)

OPTIONS FOR MAIN PUMP Grundfos UP Series Circulator Stainless steel protects against corrosion 3 Speed Super-Brute technology Integrated removable check valve Highest starting torque in its class Quick connecting terminals 3 yr warranty Cost: $200-$400

PUMP PERFORMANCE CURVE CLOSED SYSTEMS-UP SERIES

BELL & GOSSETT WET ROTOR CIRCULATORS Heat resistant, polypropylene impeller with closed design improves operating efficiency Dura Glide Bearing System incorporates several components working together to eliminate seasonal freeze-up Face plate and rotor sleeve feature corrosion resistant stainless steel Cost : $100 - $300

PUMP PERFORMANCE CURVE WET ROTOR CIRCULATOR – NRF SERIES

HEAT EXCHANGER GEA FP HYDRONIC SERIES Grazed Flat Plate 3”X 8”, 14 plates, 8 5 Psi PD Higher heat transfer co-efficient High pressure ratings Smaller size & weight Cost: $200

STORAGE TANK W/INTEGRATED HX SOLARIDE HE SERIES Heat exchanger: copper tubing wrapped & secured to the tank. Double wall, vented design for leak detection Anode rod equalizes aggressive water action for prolonged tank life Temperature and pressure relief valve included Max Pressure 150 Psi Pressure Drop thru 2Gpm is 4.8 ft Cost : $1700, 6 yr Limited Warranty

PLUMBING PIPES COPPER Impermeable to contaminants & Biostatic Will not burn or give off toxic fumes when exposed to fire Withstand rapid temperature & pressure changes Can leach lead/copper into water supply Cost :Cerro 3/4 “ x 10 $18 PVC Resistant to corrosion & abrasion Lightweight, high impact strength No water hammer Easy, cost-effective installation compared to copper Relative price stability over time Cost: 3/4 In. x 10 Ft. $2

Flat Plate Solar Collector – Sunmaxx M2 Thermal f-value Output

Flat Plate Solar Collector – Sunmaxx M ft 2 aperture area 0.35 gpm flow rate Lower cost Smaller surface area and slower flow rate produce less hot water than SH Would handle 39.4% of hot water needs

Flat Plate Solar Collector – Enerworks SH10US Thermal f-value Output

Flat Plate Solar Collector – Enerworks SH10US ft 2 aperture area 0.52 gpm flow rate Higher cost Higher flow rate and larger surface area produce more hot water than M2 Would handle 47% of hot water needs
