Why Solar and Battery Storage are essential for Darwin homes and businesses
As Darwin continues to move towards renewable energy, solar power and battery storage are becoming essential for homes and businesses aiming to cut down on energy costs while contributing to sustainability efforts. With its abundant sunshine and the growing demand for energy independence, integrating solar and battery systems offers a multitude of benefits for both residential and commercial properties in the region. Here’s why these technologies are crucial for Darwin:
- Maximised Energy Efficiency: Darwin benefits from a tropical climate with over 8 hours of average daily peak sun hours in the dry season (May to October), making it an ideal location for solar energy generation. Solar systems paired with battery storage ensure energy captured during the day can be stored and used during peak demand periods, reducing the need for grid reliance.
- Cost Savings: By adopting solar power and battery storage, Darwin residents and businesses can significantly reduce their electricity bills. The cost of installing solar systems has dropped over the past few years, and with available government rebates, transitioning to solar is more affordable than ever, offering long-term savings on energy costs.
- Environmental Impact: Solar energy is a clean and renewable energy source that helps reduce carbon footprints. With increasing focus on sustainability, the integration of solar and battery storage supports Darwin’s efforts to lower greenhouse gas emissions while promoting clean energy solutions for the community.

Rebates and Incentives for Solar, Batteries, and more in Darwin
The NT Government continuously makes an effort to deliver solar rebates and incentives to its residents that encourage more people to switch to solar.
Home & Business Battery Scheme (HBBS)
HBBS allows households and businesses $6,000 grant when they buy and install solar panels with eligible batteries and inverters. Those with existing solar batteries and inverters may also get HBBS as long as the battery storage is at least 7 kWh.
Small-scale Technology Certificates (STCs)
STCs can be exchanged for cash and deducted from the overall cost of the solar system. The number of STCs varies based on the size and location of your solar system.
Feed-in Tariffs (FiTs)
Your energy retailer is the one who will provide FiTs when you export excess energy back into the grid. FiT rates are based on your energy retailer, which is why you should take the time to find the right energy retailer to ensure you get the best rates possible.
