Battery replacement cost included ? #7

Closed shakythesherpa closed 8 years ago

shakythesherpa commented 8 years ago

Is the battery replacement cost which is the major recurring cost for a solar home system included? Does the input parameter for "Solar Home System Battery Maintenance Labor and Material Cost per Kilowatt-Hour per Year" supposed to include it?

In the reviewing the output costs.csv file in the summary folder, there is a column for solar_home_battery_replacement_lm_cost_per_year reported but this is not shown in the input parameters. How is this incorporated would be good to know.

The maintenance cost is separate from the replacement cost. The replacement cost is the installation cost divided by the lifetime in years.

Input

solar_home_battery_installation_lm_cost
solar_home_battery_lifetime_in_years

Output

solar_home_battery_replacement_lm_cost_per_year =
    solar_home_battery_installation_lm_cost / solar_home_battery_lifetime_in_years
