Solar Thermal SystemsSolar Thermal Systems
• What to heat?– Space heating: radiant,
forced air, radiators, other
– Domestic H/W• What size?
– Home heat load calculation
– Bedrooms and baths• What types for NAZ?
– Drain down– Glycol
• What Technology?– Evacuated tubes– Flat plate
Understand yours or your client's lifestyle requirements
and personal goals for solar thermal
• Where to put equipment?– Collectors on the roof: solar access, azimuth,
altitude, truss load, roof surface, pitch, gutters
– Solar storage tank: size 80 to 1000+ gallons, shape and material
– Pipes: noise, ¼” per foot drainage, insulation, keep them short & straight
– Back-up heating: tank or tankless
• Other considerations….– Maintenance– Rainwater catchment– Snow (sun block & safety)– Heat dumps (hot tub?)– Rebates and tax credits

Solar PV SystemsSolar PV Systems
• How Much Electricity?– 100%
– Off-set peak loads
• What types for NAZ?– Grid Inter-tied
– Off-grid
• What Technology?– Crystal
– Thin film
– Other
Understand yours or your client's lifestyle requirements
and personal goals for solar electricity
• Where to put equipment?– PV Modules: solar access, azimuth,
altitude, close to inverter
– PV Mount type: rack, pole, rooftop (roof surface, pitch truss load and gutters), venting
– Battery box (vented)
– Back-up electricity: grid, batteries and/or generator (noise and fuel)
• Other considerations– Maintenance
– Rainwater catchment
– Snow (sun block & safety)
– Rebates and tax credits

Rainwater Catchment SystemsRainwater Catchment Systems
• How much water?– Irrigation– Potable– All water (off-grid)
• What types for NAZ?– Clean air = clean water– Freeze protection
required• What Technology?
– Fully buried: fiberglass and metal
– Above ground or partially buried: poly and metal
Understand yours or your client's lifestyle requirements
and personal goals for solar thermal
• Where about equipment?– Simple roof design is best– Gutters must be STRONG, downspouts
min 3 inches– All fill pipes must slope ¼” per foot– Storage tank(s): near home or remote– Pumps, filtration and purification– Back-up water – city or hauled– Plumbing with constant water must be
freeze protected, large tanks do not
• Other considerations– Maintenance– Snow
