Darwin is one in every of Australia’s northernmost cities, and its location within the sunny tropics makes it among the best locations in Australia to put in a solar PV system.

This article covers the fundamentals of what you have to learn about going solar in Darwin.

How a lot power do solar panels produce in Darwin NT?

Although it in all probability goes with out saying, it’s value mentioning that solar panels solely produce electrical energy throughout daylight; the precise quantity of energy produced on a given day relies on the depth and period of the sunshine.

The common Darwin roof will obtain a mean of about 5.9 hours of ‘peak sun’ per day on common over the course of a 12 months, in accordance with figures from the Bureau of Meteorology making it one of many highest performing solar cities in Australia.

The quantity of energy really produced by your solar system will depend upon the scale of the system that you’ve put in and its orientation. The desk beneath gives an indicative information as to how a lot energy varied, well-liked residential system sizes would produce per day (averaged all year long) in good situations.

They haven’t come down in worth but as many had been forecasting and we nonetheless round $1,000 per kWh for a residential battery.

At Solar Choice we’re following these costs very carefully and we frequently carry out an evaluation of the monetary return of batteries in our ‘Are solar batteries worth it?‘ article. The conclusion we have drawn is that from a purely economic standpoint, batteries don’t fairly make sense simply but.

See the beneath 3 situations now we have assessed to find out the payback interval for an appropriately sized solar and battery system in every case. Note the use circumstances have totally different energy utilization load profiles which impacts their financial savings.

User Case Solar and Battery Solution Total Year 1 Savings Payback Period Solar & Battery Payback Period Battery Only
Young Adults / Older Family 5kW of Solar Panels and a 3.5 kWh battery $1,379 9.6 Years > 20 years
Retirees / Young households 6.6kW of Solar Panels and a 6.5 kWh battery $2,083 8.2 Years > 20 years
Big Energy User 13 kW of Solar Panels and a 13.5 kWh battery $3,595 8.8 Years > 20 years

To see all of our assumptions and the methodology of this evaluation see our full article.
