The Hidden Culprits: Wiring and Connection Losses in PV Systems Spokane, Washington

When homeowners think about solar energy efficiency, they often focus on panels and inverters. However, two less-visible factors—wiring and connection losses—can also impact your system’s performance. While these losses might seem small, over time, they can significantly reduce the energy your system delivers. Let’s uncover these hidden culprits and explore how to address them effectively.

Wiring Losses: The Flow of Electricity

Think of electricity as water flowing through a pipe. The size and length of the pipe determine how easily the water flows. Similarly, in a solar system, wires carry electricity from your panels to the inverter and beyond.

• Smaller wires create more resistance, much like a narrow pipe causing water to flow slower.
• Longer wire runs increase resistance, resulting in energy loss before it reaches your home.

These resistive losses, while small in percentage, can add up to noticeable inefficiencies over the life of your system.

The Solution: Proper wire sizing is key. Using thicker, high-quality wires and minimizing the length of cable runs can drastically reduce these losses.

Connection Losses: Where Inefficiencies Lurk

Every connection point in your solar system—whether it’s at a junction box, a connector, or a terminal—represents a potential weak spot.

• Poor-quality connectors can degrade over time, causing resistance to increase.
• Improper installation, like loose or poorly crimped connections, can lead to energy leakage or even safety hazards.

Over time, even minor inefficiencies at these points can affect the overall performance of your system.

The Solution: High-quality connectors and professional installation standards are critical. At Independent Power Generation, we ensure all connections are secure and built to last, reducing the risk of energy loss or system failure.

Best Practices for Minimizing Losses

At Independent Power Generation, we adhere to industry-leading standards to mitigate wiring and connection losses:

• Wire Sizing: Carefully calculate wire gauge based on system size and layout to optimize efficiency.
• Connector Quality: Use only properly rated, UL listed connectors designed for solar applications. Compression terminals and lugs are preferred. Use of wire ferrules is recommended with stranded wires.
• Installation Expertise: Our NABCEP-certified professionals ensure every connection is solid and compliant with electrical codes.
