What is Off-Grid Solar?
Off-grid solar systems are self-sufficient, stand-alone systems that are not connected to the traditional electrical grid. They are designed to provide power to remote or isolated areas where grid-tied systems are not practical or cost-effective. This knowledge module will provide an overview of the key concepts, technologies, and strategies that are used to design, install and maintain off-grid solar systems.
System Design and Component Selection:
This section will cover the design and component selection strategies that are used to ensure that an off-grid solar system is efficient, reliable and cost-effective. This includes the selection of solar panels, inverters, batteries, charge controllers and other components. Specific examples in this section include the use of monocrystalline or polycrystalline solar panels, string or micro inverters, lead-acid, Li-ion or other type of batteries, and PWM or MPPT charge controllers.
Installation and Maintenance:
This section will cover the installation and maintenance strategies that are used to ensure that an off-grid solar system is properly installed and operates efficiently over time. This includes the use of proper wiring and grounding techniques, the selection of appropriate mounting hardware, and the implementation of a regular maintenance schedule. Specific examples in this section include the use of conduit, MC4 connectors and other types of wiring, the selection of ground or roof-mounted racking systems, and the use of regular cleaning and monitoring practices to ensure optimal performance.
