Chapter Four Sizing and Engineering
Once the type of collector, wall or roof, has been decided upon, the size is largely determined by the building. On conventional buildings the collector will usually use almost all available space.
Once the type of collector, wall or roof, has been decided upon, the size is largely determined by the building. On conventional buildings the collector will usually use almost all available space.
To prevent overheating in active systems, the size of the solar storage tank increases with the size of the collector -- typically 1.5 gallons per square foot of collector.''
Depending on your region and size of system solar can provide between 50-90% of your domestic hot water needs. A properly sized system will provide almost all of a home''s hot water in the
Divide the total ft2 of your array by the aperture area of the solar collector to determine the number of solar collectors needed for your array and you have successfully sized your solar
When you choose the size of solar collector, you must consider two key factors: insolation level and energy requirements. Energy requirement will usually take into account water volume and
The sizing worksheet provides a general idea of collector and storage tank sizes, but solar hot water system companies and installers can conduct a more precise assessment.
Solar collectors come in a set of standard sizing of 10, 12, 15, 18, 20, 22, 24, 25 or 30, depending on your region. Of course you can also combine collectors to increase the size.
Divide the total ft2 of your array by the aperture area of the solar collector to determine the number of solar collectors needed for your array and you
