Understanding the NZ 2024 solar panels cost helps you make informed decisions. Solar panel cost varies based on several factors, including system size and installation complexity.

Batteries (26.5%):
Batteries make up 26.5% of the cost. They store excess energy generated by the panels for use when sunlight is not available, ensuring continuous power supply.

Panels (18.5%):
Panels account for 18.5% of the total cost. They convert sunlight into electricity, and their quality and type directly impact the system’s efficiency and overall cost.

Installation (19%):
Installation costs, making up 19%, cover labor, mounting equipment, and materials required to securely and optimally set up the panels on your roof or property.

Inverter (13.2%):
Inverters represent 13.2% of the cost, converting the direct current (DC) electricity produced by the panels into alternating current (AC) electricity, which can be used in your home or business.

Balance of System (BOS) (10.6%):
BOS, at 10.6%, includes additional components such as wiring, switches, and monitoring systems, essential for the smooth operation of the solar power system.

Freight (6.9%):
Freight costs make up 6.9% of the total, covering the transportation of the solar panels and equipment to your location.

Service (5.3%):
Service costs, at 5.3%, include maintenance, monitoring, and post-installation services required to ensure the system’s long-term efficiency and performance.

With Affordable solar costs, how much can you save?

This is based off our standard 10 panel Starter Package over 35 years

Assumptions:

The projected energy cost is calculated by considering a 3.0% increase in energy cost each year, due to trends in the raising cost of energy. This estimate is based on Selected preferences, current energy costs and the position and orientation of your roof to calculate the efficiency of the system. Projections are based on estimated usage of 6875 kWh per year (NZ Average), assuming The following Rates:
