What type of solar system do i need?
That depends on the size of your home and your energy usage
Our first step is to consult with you to get an understanding of your energy usage including any possible upgrades such as replacing gas cooking or water heating with electric, or adding ducted heat pumps. Once we understand your unique situation, we can recommend a system that will generate real world savings for your household, or we can go to the next step and provide a full off-grid solution for total independence

Commercial Solar for Wellington Businesses
Installing solar on your commercial building is a smart, future-focused investment—especially in the Wellington region, where rising energy costs and strong sustainability expectations are driving businesses to rethink how they power their operations.
Why Go Solar for Your Commercial Building?
Lower Operating Costs
Solar significantly reduces your electricity bills by generating clean energy on-site. For businesses with high daytime power usage, solar can offset a large portion of grid consumption, delivering long-term savings and protection against rising energy prices.
Strong Performance in Wellington Conditions
Wellington’s climate offers excellent solar generation potential, even on cooler or overcast days. Modern commercial-grade solar panels are designed to perform efficiently in high wind zones and variable weather, making them well suited to the region.
Improved Sustainability & Brand Value
Installing solar demonstrates a clear commitment to sustainability. This not only reduces your carbon footprint but also strengthens your brand, helping you meet ESG goals and appeal to environmentally conscious clients, partners, and staff.
Long-Term Asset Value
A commercial solar system is a long-life asset that adds value to your building. With minimal maintenance and predictable energy generation, solar delivers reliable returns over decades.

Solar System Maintenance & Future Upgrades in Wellington
Regular maintenance is essential to ensure your solar system continues to operate safely, efficiently, and at peak performance—especially in the Wellington region, where strong winds, coastal air, and variable weather can impact system components over time.
Why Solar Maintenance Matters
Maximise Energy Output
Dust, salt residue, debris, and general wear can reduce system performance. Routine inspections and servicing help identify and correct issues early, ensuring your system consistently delivers the energy savings it was designed for.
Protect Your Investment
A solar system is a long-term asset. Proactive maintenance helps extend the life of panels, inverters, and electrical components, reducing the risk of costly repairs or premature replacement.
Ensure Safety & Compliance
Over time, connections, mounting systems, and electrical components can loosen or degrade—particularly in high-wind environments like Wellington. Regular maintenance ensures your system remains safe, compliant, and structurally secure.
Early Fault Detection
Monitoring and scheduled servicing allow potential issues to be identified before they impact performance or cause downtime, helping avoid unexpected energy losses.
Planning for Future Upgrades
As energy needs change and solar technology continues to advance, many systems benefit from future upgrades. Whether you’re expanding your business, adding battery storage, integrating EV charging, or upgrading inverters and monitoring systems, a well-maintained solar system provides a strong foundation for future improvements.
Designing and maintaining your system with upgrades in mind ensures new components can be seamlessly integrated, maximising both performance and return on investment.
