Grid-Tied Solar Power

Grid-tied solar systems are the most common type of residential solar installation. These systems connect to the local utility grid, allowing homeowners to use solar power and draw electricity from the grid when needed.

Benefits

• Cost Efficiency: Save on electricity bills and earn credits through net metering.
• Reliability: Continuous power supply by drawing from the grid when solar is insufficient.
• Environmentally Friendly: Reduce your carbon footprint.

How It Works

Grid-tied systems consist of:

• Solar Panels: Typically made from monocrystalline or polycrystalline silicon, these panels convert sunlight into electricity.
• Inverter: Converts the direct current (DC) electricity generated by the panels into alternating current (AC) electricity used by your home.
• Mounting Systems: Roof mounts or ground mounts, made from aluminum or stainless steel, securely position the panels.
• Net Meter: Tracks the electricity fed back into the grid, allowing you to earn credits.

Examples

• Suburban Home in Massachusetts: A family of four installed a grid-tied system with 20 monocrystalline solar panels, a 5 kW inverter, and roof mounts. This setup reduced their electricity bills by 60% and earned them credits through net metering.
• Urban Residence in Boston: A townhouse owner installed 12 polycrystalline solar panels and a 3 kW inverter using roof mounts, saving 50% on energy costs while maintaining reliability.
