Capturing Solar Energy

Choosing premium solar panels is vital for optimising your solar energy system. High-quality panels ensure superior energy conversion rates, greater durability, and enhanced returns on your investment. Our premium panels efficiently capture sunlight, converting it into direct current (DC) electricity. This raw energy is then ready for the inverter to transform into usable power for your home, demonstrating the critical importance of panel efficiency from the very start.

Why Choose a Grid-Tied System


A grid-tied solar power system offers homeowners an efficient and cost-effective way to harness solar energy and lower electricity costs. Designed for areas with dependable grid service, it enables savings through reduced energy consumption and provides financial benefits via export credits on utility bills.

ZEN Energy design asset


Lower Installation Cost
Generally less expensive to install than hybrid battery and off-grid systems.

Eligibility for Export Credits
Homeowners can sell excess generated electricity back to the power grid, reducing energy bills further.

Reduced Carbon Footprint
Utilises clean solar energy, significantly lowering greenhouse gas emissions associated with home energy use.


Dependence on Grid Availability
The system relies on the electrical grid to function and cannot produce power during grid outages.

No Power During Outages
Without a battery backup, the system will not supply electricity during power outages.
