Copyright 2010, Solar Thermal Systems

Copyright 2010, Solar 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 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

Copyright 2010, Solar PV Systems

Copyright 2010, Solar 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

Copyright 2010, Rainwater Catchment Systems

Copyright 2010, Rainwater 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
