Design defaults
Project profiles that supply defaults for new projects.

What this is for
A profile is what a new design copies when it is created. It is a starting point, not a live binding. Changing the team's default tilt never re-lays an array a customer has already signed off. The page says so because nothing else in the product would tell you.
Steps
- Open Design defaults.
- Profiles lists each one with its tilt, target DC:AC ratio and soiling. The one marked Team default is what a new project uses when the team has not picked another.
- Pick a profile to edit it in the panel beside the list: Mechanical, Electrical, Conditions, Drawings and Financial. The financial set is the analysis period, install time, discount rate, utility escalation and income tax rate a new model starts from. Save profile. Those values land on the next design, not on anything already drawn.
- New profile, at the foot of the list, adds a second starting point - a rooftop set and a ground-mount set, for example. It starts from the product's own defaults, not from a copy of the profile you have open. Make default and Delete sit at the head of any profile that is not the default. The default offers neither: a team must keep one.
There is no default azimuth. The equator-facing direction is computed from each site's own latitude, so a hemisphere assumption cannot sit on the team and then be copied onto every project.
Conductor sizing and the other market conventions come from the team's market on Members, not from a preference on this page.
Tips and common mistakes
- Editing a profile does not change existing designs. If an array is already laid out, change it in the designer.
- Row spacing of
0means the layout engine solves it. It is not "no spacing". - Export limit of
0 kWis not "no limit". The hint on the field says so. - Published model coefficients (the cell-temperature and sky models) are not here. They are constants in the engine. What you can override - soiling, AC losses, availability, degradation - is.
