Bill highlights

We highlight the words customers often miss

A bill is not just one total amount. The important information is hidden in the details.

⏰

Peak / Shoulder / Off-peak

Shows whether you are paying more because energy is used during expensive periods.

💵

Supply Charge

A fixed daily cost that still applies even when usage is low.

☀️

Feed-in Credit

Low solar export value can make self-consumption and battery storage more important.

🔋

Battery Opportunity

High evening usage may indicate stronger battery suitability.

Why bills go up

Common reasons your home electricity bill increases

🌙

More evening usage

Why bill goes up: Solar produces during the day, but many homes use more power after sunset when grid rates are higher.
How to reduce: Use timers, shift loads to daytime where possible, and review battery storage if evening usage is high.
📈

Wrong tariff or peak rates

Why bill goes up: Time-of-use tariffs can make electricity more expensive during peak periods, especially 6pm–9pm.
How to reduce: Review whether your current tariff suits your usage pattern, solar system and EV charging habits.
🚗

EV charging at expensive times

Why bill goes up: Charging an EV at peak rates can quickly increase the household electricity bill.
How to reduce: Move charging to solar hours or off-peak periods and consider smart charger controls.
⚠️

Low solar feed-in credit

Why bill goes up: Exporting solar for a low feed-in tariff may not offset the cost of buying electricity later.
How to reduce: Increase self-consumption with daytime loads, hot water timing, EV charging or battery storage.
How to reduce

A better bill starts with the right action plan

We do not start by selling a system. We start by reading the bill and identifying where the cost is coming from.

✅

Shift usage

Move pool pump, dishwasher, washing, heating/cooling and EV charging to lower-cost times.

☀️

Use more solar

Increase daytime self-consumption instead of exporting too much power at low credit.

📊

Check tariff

Compare flat-rate, time-of-use and controlled-load options based on usage pattern.

🔋

Battery review

Assess whether evening usage and tariff structure support battery storage.

Home battery program

Battery programs can help — but not every home benefits equally

Some homes can benefit from a battery through better solar self-consumption, evening usage reduction, backup power and possible VPP/program participation. But if usage is already low, solar export is small, or the customer does not participate in the program requirements, the benefit may be limited.

Check Battery SuitabilityLearn Program Details

✅ Customers may benefit when

  • High evening electricity usage after solar hours
  • Low solar feed-in credit and high grid import rate
  • Wants backup power or better energy independence
  • Willing to follow VPP/program participation rules

⚠️ Benefit may be limited when

  • Very low household electricity usage
  • Most energy is already used during solar hours
  • No interest in program/VPP participation
  • Battery size is not matched to actual bill data
