10.7) Realistic Behaviour (cont'd)

We can now experiment with the interest-rate and can immediately see (from the view) how much of an impact it has. When you keep the subsidies to their default values and vary the interest-rate from 0 (65-70% adoption, left picture), via 0.05 (5-10% adoption, middle picture), to 0.1% (no adoption at all, right picture), you can see that the way people discount is one of the key parameters for PV adoption.

Try to find the interest rate tipping point above which adoption drastically drops. (Hint: Create a new experiment in BehaviourSpace to vary the interest rate and measure total PV generation.)
