There is an engineering principle behind every audit we run: the cheapest kilowatt-hour is the one you never have to generate. Before sizing solar or storage, it pays to understand where your energy is actually going, because the answer is often surprising, and frequently fixable for very little.
Where the energy hides
- Old electric hot water systems running on peak tariffs instead of shifting to daytime solar.
- Standby and 'always-on' loads quietly drawing power around the clock.
- Heating and cooling fighting poor insulation or bad thermostat schedules.
- Ageing motors, pumps and refrigeration in commercial settings running well below their efficient point.
Why the order matters
Sizing a solar system to a wasteful load means paying to generate power you did not need in the first place. Fix the waste first, and you often end up with a smaller, cheaper system that covers more of your real demand. The audit is not an upsell. It frequently shrinks the recommendation.
Half the wins in an audit cost nothing but a schedule change. The other half pay for the audit several times over within a year.
What you walk away with
A Guwing Green audit gives you a clear picture of your load profile, a ranked list of efficiency wins, and, if it makes sense, a properly sized solar and storage recommendation built on the corrected demand. No guesswork, no generic profiles.
