Workflow in 7 steps
The application is filled in from left to right. Steps 1 to 6 define the project; pressing Simulate system calculates everything and enables step 7.
| Step | What you define | Documentation |
|---|---|---|
| 1 · Project setup | Installation and client type | Project setup |
| 2 · Site and roof | Location, weather data, horizon, albedo; roof planes and objects that cast shade | Site · Roof |
| 3 · Consumption and tariff | Client's consumption curve, special loads; electricity tariff | Consumption · Tariff |
| 4 · Design | Equipment, placement, topology and final layout | Equipment · Design |
| 5 · Economics | Costs, financial assumptions, loan, replacements | Economics |
| 6 · Advanced settings | Calculation models, losses, electrical limits, uncertainty | Advanced settings |
| 7 · Scenarios and report | Results, comparator, PDF report and offer | Results |
What is mandatory
To simulate you need at least a location and at least one roof plane. Everything else has reasonable default values for a typical home, so you can get a first result quickly and refine it later.
What happens when you simulate
- The weather year for the location is obtained (8,760 h).
- The consumption curve and the tariff are built.
- In automatic mode the installation is sized; in manual mode your topology is used.
- Each string is simulated hour by hour, aggregated at the inverter and balanced against consumption (and the battery, if there is one).
- The economics and the uncertainty are calculated and the report is prepared.
The details of each phase are in Calculation chain.
Iterate
Change whatever you need and press Simulate system again. To compare alternatives (with and without a battery, another orientation, another tariff) save each result as a scenario.
