Both consist of solar panels and an inverter to convert DC to AC power. Off-grid solar remains permanently disconnected from the grid. It therefore needs to work differently than an on-grid installation. With an on-grid system, the inverter sends energy into your home, which also connects to the grid via a meter.
On-grid solar energy systems – also known as grid-tied systems – provide a reliable power supply that reduces dependence on the National Grid. However, they remain connected to the grid, meaning they can draw energy from it in when their own solar power production isn’t sufficient for their needs.
The resulting direct current (DC) is converted by a solar inverter into the alternating current (AC) needed to power homes and domestic appliances. There are two main types of solar systems: on-grid and off-grid. Both consist of solar panels and an inverter to convert DC to AC power. Off-grid solar remains permanently disconnected from the grid.
As such, savvy environmentally-friendly households are exploring ways to generate their own electricity on-site to lessen reliance on the power grid. Standard solar energy systems provide the main solution here. Others consider taking their use of solar further by completely eliminating the need to rely on the grid.
Grid-tied and off-grid solar systems differ primarily in their connection to the main energy grid. A grid-tied solar system is primarily connected to the electricity grid and can both draw from and contribute to it. This is beneficial when solar generation is not enough or during nighttime.
Here are some of the useful tips when choosing an off-grid solar system: 1. Assess Your Energy Needs: Begin by conducting an energy audit to determine your average daily power consumption. This provides a baseline upon which your system will be designed.
