Solar System Upgrades


Is your Solar System delivering you the ROI you are expecting? If not, don’t despair. We have plenty of solutions!

In most instances, good quality commercial size installs don’t need upgrading because the system will have been designed based on your bills and usage. If you have found that your system is not meeting your needs anymore, we suggest a system health check or maintenance visit to make sure your system is generating at an optimal level. If you’ve had a significant change in your energy needs, we can organise a site visit to arrange an assessment of your capacity to increase array sizing.

Choose The Latest in Solar Batteries and Storage For Your Home

What is a Solar Battery and What Can It Do? Most Solar system owners have realised that a Solar PV system can only save them so much on their energy bill. When the sun isn’t providing any energy for your panels (like at night), your energy retailer provides you with electricity. During the day, if your system is generating more power than your home is consuming, your retailer will pay you for any excess that you send back to the power grid. However, the purchase price for that excess power (feed-in tariff) will be significantly less than what your retailer will charge you if you then need to buy power from the utility at peak periods.
