The following main materials are required to install an off-grid solar system:
Solar panels (photovoltaic modules)
Solar panels are the core part of the solar system and are responsible for converting solar energy into electricity.
Solar Bracket
Used to install and fix solar panels, ensuring that they are stable and receive sunlight at the best angle.
Solar Charge and Discharge Controller
Also known as MPPT (Maximum Power Point Tracking) controller, it is used to manage the electrical energy generated by the solar panels, ensure that the panels output at maximum power, and control the charging and discharging process of the battery.
Battery
Used to store the electrical energy generated by solar panels for use by the load when needed. The capacity and type of battery (e.g., lead-acid battery, lithium battery, etc.) need to be selected according to the needs and budget of the system.
Off-grid inverter
Converts direct current from a battery into alternating current for use in a home or commercial electrical device.
Cables and connectors
used to connect components such as solar panels, controllers, batteries, and inverters to ensure the efficient transmission of electrical energy.
Distribution box
used for centralized management and distribution of electrical energy, including switches, fuses, terminal blocks, etc.
Lightning protection and grounding equipment
used to protect the system from natural disasters such as lightning and ensure the safe operation of the system.
In addition, depending on the specific installation environment and needs, other auxiliary materials such as installation tools, sealants, insulation, etc. may be required. Before installing an off-grid solar system, it’s best to consult with a professional solar system installer or engineer to ensure that you get all the necessary materials and equipment.
