Solar Collector Inclination
Angle of Inclination
Difference between Local Latitude and Roof Angle
General Information |
The most desired angle
of Inclination to mount the solar collector is the local Latitude. Positive difference
between Latitude and Roof angle results better system performance in winter. Lower Solar
Collector mounting angle than the local Latitude will result in greater system performance
in summer.
Variations of Solar Collector tilt angle for architectural reasons can be compensated with
addtional Thermomax tubes. |
To heat 375 liters of water at a job site with a local Annual Insolation of
1400 hours, roof orientation of 30 ° West of South, and an inclination difference of 10
°, you need 45 Thermomax tubes.
|
When designing a Thermomax domestic solar water heating system, determine
first how much hot water the family will be using per average
day. Next find latitude, the amount of solar insolation, and
number of hours of available sunshine at the job site location.
Consider the effects of Solar Collector orientation and Solar
Collector inclination. |
| Example: |
Size a Thermomax Solar Water heating system for
a family of five with a hot water requirement of 50 liters hot water per day, per person.
The Annual Insolation is 1400 hours. Orientation of the roof is 30 degrees West of South.
The local latitude is 45 degrees and the roof angle is 35 degrees (inclination difference
10 degrees).
45 Thermomax tubes will supply hot water requirement of the
above example by following Thermomax suggestions. For best result a 375 liters solar hot
water storage tank should be used. |
