what is the cost of solar system batteries

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.

We’re saving even in winter, and it’s great powering our home and charging our car. James provided clear details and the installation was seamless. Excellent follow-up service too. Thanks, Sunshine Solar team!”
