Post-install bill check

Already have solar but your bill is still high?

A high bill after solar does not always mean the system failed. It may be tariff timing, low self-consumption, poor export value, battery fit, controlled load, or a plan mismatch.

Checks solar export and feed-in clues where visible
Flags tariff or usage timing issues
Helps decide whether battery, plan switch, or behaviour change comes first
What this finds

Use this before adding a battery or changing retailers. The bill may show a cheaper fix than another major purchase.

What GridBeater checks

A buyer-side sanity check before the sales step.

No-spam flow
Export value

Low feed-in tariffs can make exported solar less valuable than self-consumed solar.

Usage timing

High evening usage can leave bills high even with strong daytime generation.

Retailer plan

The wrong plan can reduce the value of solar or raise supply and usage costs.

Battery fit

A battery can help some homes, but only if the bill pattern supports it.

Red flags worth checking
High grid import after sunset
Low feed-in tariff with high export
Supply charges dominating a low-usage bill
Controlled load hiding hot-water usage
Battery quote with no bill-based payback

Common questions

Why is my bill still high after solar?

Common reasons include evening usage, low feed-in tariffs, poor self-consumption, tariff mismatch, controlled load, seasonal usage, or system/export limits.

Should I add a battery?

Maybe, but check the bill first. A battery is strongest when there is enough evening usage and the tariff supports storing solar.

Can switching retailer help?

Sometimes. Solar plans vary across feed-in tariffs, usage rates, and supply charges. The right plan depends on your actual import and export pattern.
