Present Value of PhotoVoltaics (PV2) is an app that allows homeowners to determine a complete cost of ownership for residential rooftop solar PV systems.
User cannot delete an existing pre-populated value (you can type over the value by highlighting the entire thing and typing over it, but not simply delete the value and then type in a new value)
Solution - allow all pre-populated values to be deleted: study period, real discount rate, inflation rate, panel lifetime, inverter lifetime, degradation rate, inverter replacement costs, and maintenance costs. The energy escalation rates values can be deleted. So you can use those as an example of how we want the other variables to work.
