Scenario comparator

A scenario is the summary of a simulation saved under a name. It is used to compare alternatives: «with and without battery», «another orientation», «another tariff», «with optimizers».

How to use it

1. Simulate the base configuration.
2. In Scenario comparator, type a name and press Save this result as a scenario.
3. Change whatever you want to compare (battery, orientation, tariff…) and simulate again.
4. Save that result too.
5. The table shows the scenarios side by side.

What the table shows

• The configuration differences between scenarios (in a different shade).
• The metrics of each one: power, production, self-consumption, savings, investment, payback, NPV, IRR, LCOE…
• In green, the best scenario in each row (when there is more than one and the metric has a «best»). If none recovers the investment, there is no best payback.
• A ★ marks the scenario that matches the result you see above.
• A bar chart with the annual savings and NPV of each scenario.

Things worth knowing

• Only numbers (the summary) are saved, not the complete engine: that is why they are saved with the project.
• In off-grid installations savings and NPV are not compared (they have no tariff).
• Scenarios can be removed from the list.
• If there are scenarios, the PDF report can include a Scenario comparison section.
