What Makes Up the Cost of a Solar Panel Installation?
Understanding solar panel costs in NZ helps you make informed decisions. The price of a solar panel system varies based on several factors, including system size, panel quality, and installation complexity. Here is how the cost of a typical solar panel installation breaks down.
1. Panels (25.2%): Panels, making up 25.2% of the cost, convert sunlight into electricity. Their quality and type affect overall efficiency and cost.
2. Installation (25.8%): Installation is the largest cost at 25.8%, covering labor, mounting equipment, and materials for safe, optimal setup.
3. Inverter (18%): Inverters account for 18% of the cost, converting DC electricity from panels into usable AC electricity.
4. Balance of System (BOS) (14.4%): BOS, at 14.4%, includes additional components like wiring, switches, and monitoring systems, ensuring smooth operation.
5. Freight (9.4%): Freight costs make up 9.4% and cover transporting the solar panels and equipment to your location.
6. Service (7.2%): Service costs, at 7.2%, include maintenance, monitoring, and post-installation services to ensure system efficiency.
Panels (25.2% of solar system cost)
The solar panels themselves constitute 25.2% of the total cost. These are the most visible component of a solar power system and are responsible for converting sunlight into electricity. The type and quality of the panels can significantly influence the overall cost and efficiency of the system.
Install of system (25.8% of solar system cost)
Installation costs account for the largest portion of the total expense at 25.8%. This includes labor, mounting equipment, and other materials required to securely install the panels on your roof or property. Professional installation ensures the system is safely and optimally set up to maximize energy production.
Inverters (18% of solar system cost)
The inverter makes up 18% of the total cost. It is a crucial component that converts the direct current (DC) electricity generated by the panels into alternating current (AC) electricity, which can be used in your home or business. High-quality inverters are essential for the efficient functioning of the solar power system.
Balance of Systems (14.4% of solar system cost)
BOS includes all the additional components and equipment needed for the solar power system, excluding the panels and inverter. This category, comprising 14.4% of the total cost, includes wiring, switches, mounting hardware, and monitoring systems. These components ensure the system operates smoothly and safely.
Freight & Transport (9.4% of solar panel system cost)
Freight costs, which make up 9.4% of the total, cover the transportation of the solar panels and equipment to your location. This can vary depending on the distance and logistics involved in delivering the materials.
Service & Applications (7.2% of solar power system cost)
Finally, service costs represent 7.2% of the total expense. This includes maintenance, monitoring, and any post-installation services required to keep the solar power system functioning efficiently over its lifespan.
How Much Can You Save with Solar Panels?
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:
