£6.89 estimated saving from Orza's plan, last 7 days
Orza's plan is advice. Nothing is sent to your battery.
Your grid power has cost £46.75 so far this month, heading for about £60.42 by the end of October.
This month so far
Worked out, not measured. Each reading gives the power at your roof, your home, the battery and the meter; what went where is split by one rule: your roof runs the home first, then the battery, then the grid. The meter counted 288 kWh from the grid; 2.4 kWh of it isn't drawn, lost on its way into the battery and in rounding.
Priced from your inverter's own readings; your supplier publishes its meter reads a day or two later.
This is your battery's own schedule. What Orza's plan would have paid is on Savings.
Orza plans on the weather forecast for your roof, scaled by what your roof has made against that forecast over the last two weeks. Each day: the sun the day's first plan, made just after midnight, planned on, and what came.
Measured up to 16:30, updating every half hour; the dashed line ahead is the sun the current plan expects.
Open a day to see it five minutes at a time.
