When navigating the world of solar energy, you might notice that many companies often recommend a 6.6 kW solar system. But why is this particular configuration so common?
Optimal Configuration for Cost Efficiency
A significant reason lies in the pairing of solar panels with inverters. Typically, a 6.6 kW solar system is paired with a 5kW inverter. This setup is not only cost-effective but also maximizes the energy output within regulatory constraints.
Maximizing Panel Output
By using up to 6.6kW of panels with a 5kW inverter, homeowners can stay within legal limits without needing a larger inverter. This helps avoid the extra costs associated with upgrades to bigger or additional inverters, which could otherwise increase the overall price.
Enhanced System Performance
Oversizing the array of solar panels relative to the inverter capacity is a strategic move. This design allows for greater energy collection during periods of lower sunlight, such as cloudy days, ensuring that the inverter is often operating at its optimal capacity.
Conclusion
In essence, the widespread quoting of 6.6kW solar systems represents a blend of regulatory compliance, cost-effectiveness, and enhanced energy performance, making it a popular choice for both solar companies and homeowners alike.
