Example 12.12
For a residential liquid-based solar space heating system, the following information is given: Annual heating load 161 GJ.
First-year fuel cost rate,CF1 = $8.34/GJ.
Area-dependent cost = C $210/m
Area-independent cost =$1,150.
Market discount rate, d= 8%.
Mortgage interest rate, dm, = 6%.
General inflation rate, i = 5%.
Fuel inflation rate, if = 9%
Term of economic analysis = 20 years
Term of mortgage load = 10 years
Down payment = 20%
Ratio of first year miscellaneous costs to the initial investment, M1 = 0.01.
Ratio of assessed value of the system in the first year to the initial investment, V1 = 1. Ratio of resale value = 0.3.
Property tax, tp = 2%
Effective income tax, te, = 35%
In addition, the solar fraction to the collector area varies as shown in Table 12.9.
