SOLAR FAQ'S

• What is the recommended size??
  
  In colder climates, a 500 square foot collector area is appropriate for domestic hot water heating in a single family home. In warmer climates, a 300 square foot collector can often do the job. For space heating, a minimum of 800 square feet of roof area is recommended.
  
  
• What is the proper orientation of a solar energy system??
  
  Ideally, the solar collectors should face as close to south as possible. However, east and west orientations can still provide significant solar energy. A system facing east or west is approximately 20% less effective than one facing south. The ideal slope for a solar energy system is roughly equal to the geographic latitude. The slope is generally not as critical as the orientation. A 10 degree change in slope will typically affect performance by 2-3%.
  
  
• How does the system integrate with my domestic hot water system??
  
  The water from the main water supply is preheated as it passes through the storage tank on its way to your primary water heater. Each BTU of solar energy used offsets a BTU that would otherwise be generated by fossil fuels or electricity. Typical solar domestic hot water systems utilize a circulating pump, solar storage tank, miscellaneous fittings and a solar differential control, specified in conformance with SRCC OG 300 requirements.
