2025 Insider Guide: Why January is the perfect time to go solar in New Zealand

14/01/2025

Power bills are exponentially on the rise and January’s long, sunny days make now the smartest time for Kiwis to embrace solar energy. Get ready to lock in huge savings, enjoy energy independence and power your home sustainably.

Brace yourself and be prepared… massive winter power bills are on their way!


Insider info suggests 2025 record-high winter power bills

Energy experts warn that this winter’s power prices could reach all-time highs. To make matters worse, extreme weather events are happening more often, leading to more frequent grid outages. For homeowners seeking stability and lower costs, solar power offers a reliable solution.

Why installing solar in January makes a lot of sense

Don’t wait until prices surge in the colder months. By going solar now, you can lock in cheaper electricity before winter hits. Generating your own power helps slash those rising bills and protects you from unexpected outages—all while making your home more energy independent.

Maximise summer sunshine for greater savings - why summer is the best time for solar generation

January is one of the sunniest months in New Zealand, making it the perfect time to switch to solar. Most towns receive over 2,000 hours of sunshine a year—even Invercargill has sunlight levels comparable to Germany, a world leader in solar adoption.

Enjoy immediate benefits

Start generating your own clean energy now, while the sun is at its strongest. You’ll quickly see lower power bills and can build up energy credits to use in the colder months.

Want to dive deeper into the numbers and learn about how much you can save during summer based on different system sizes and types of systems? Check out our comprehensive guide for maximising summer savings.
