Give one option an extra load or an export cap; Base stays as metered:
- Per option, never Basean adjustment lives on one comparison option, so the gap to Base is the load or the cap alone.
- Profile vs growtha profile row adds an hourly shape before sizing; a growth row compounds the savings a percentage a year.
- Cost after incentivesthe load’s upfront cost joins the option’s capex after STCs and LGCs; it earns no certificates itself.
- Export limitexport above the cap is curtailed and earns nothing; 0 kW models a zero-export site.
- Library edits go stalechange or delete a row an option uses and that option reads Inputs changed until it is modelled again.
Up to five loads per option, each with its own multiplier and upfront cost.
"What if they also put in an EV charger?" and "what if the network caps our export?" are the questions that follow most battery quotes. An adjustment lets one comparison option answer them with modelled numbers.
What an adjustment is
An adjustment is an additional load or an export limit carried by one option in an Analysis project. It lives on that option only; Base is never adjusted, so the difference between the two rows is the load or the cap and nothing else. Every surface that shows the option says so: chips on the option itself, on the Options card, on the deck's comparison slide and in the proposal assumptions.
The Additional Loads Library
Loads live in the Library under Additional Loads. A row is one of two kinds.
- Profile rows carry an hourly shape, with the annual kWh and peak kW shown beside it. Five of the six global rows seeded for every company are profiles: EV charger 7 kW, EV charger 22 kW, DC fast charger 50 kW, Cool room 5 kW and Heat pump hot water 3 kW.
- Growth rows carry a percentage a year over a set number of years. The sixth seed is the one growth row: Load growth 3%/yr for 5 years.
New load adds your own row: a weekday and weekend pattern, a growth rate, or an interval file you upload (CSV only, up to 25 MB, cleaned the same way as a consumption upload). Each row also carries an upfront cost. That figure is a prefill: the option gets its own copy when you pick the row, and can change it.
Setting it on a project
On Solar & Battery, open Compare options and find the Adjustments box on the option you want to change. Pick a load, then set its multiplier (2× for two chargers) and its upfront cost; an option can carry up to five loads. The Export limit switch in the same box takes a kW figure, and 0 kW models a site that may not export at all. Options are modelled on demand, so press Model options on Recommendation when you want the numbers.
What it does to the numbers
- A profile load joins the site load hour by hour before anything is sized, so the option and its baseline bill both see the bigger site.
- A growth load compounds the bill-reducing savings stream year by year. Year one is the site as metered; the uplift starts in year two.
- The upfront cost lands in the option's capex after incentives. STCs and LGCs are worked out on the solar and battery alone, because an EV charger is not an eligible system.
- An export limit curtails export above the cap in every hour, after the battery has taken what it can of the surplus. That energy earns nothing, so only the feed-in credit, payback and NPV move.
When a Library row changes
An option remembers which Library rows it used. Edit one and every option using it shows Inputs changed on the Options card until it is modelled again. Delete one and the option shows Library load missing until you re-pick a load for it on Solar & Battery. Base is never affected by either.
