What is Inverter Power Clipping on a Home Solar Power System and How To Avoid It?

Clipping is a term used in the context of solar power systems to describe a situation where the output of the system is being limited or "clipped" due to its maximum power capacity.

Solar power systems are designed to convert sunlight into electricity. This process is carried out by photovoltaic (PV) panels, which are connected to an inverter. The inverter's job is to take the direct current (DC) electricity produced by the panels and convert it into alternating current (AC) electricity, which is compatible with the electrical grid.

However, if the output of the PV panels exceeds the maximum power capacity of the inverter, the excess power will not be converted into AC electricity, but instead will be "clipped" or limited. This can happen, for example, on a sunny day when the panels are producing more power than the inverter can handle.

Clipping can be problematic for several reasons. Firstly, it means that some of the energy produced by the panels is not being used, which is wasteful and reduces the overall efficiency of the system. Secondly, if clipping happens frequently, it can reduce the lifespan of the inverter and potentially cause damage to the panels or other components of the system.

To avoid clipping with a microinverter-based solar power system, it's important to follow these steps:

  1. Accurately estimate the maximum power output of your solar panels: This information is usually available from the panel manufacturer. It's important to have an accurate estimate of the maximum power output in order to determine the right size microinverter for your system. Viridis Energy are the experts when it comes to designing your solar system.
  2. Choose the right size microinverter: Microinverters are available in different sizes, with different maximum power capacities. Make sure to choose a microinverter that has a capacity that exceeds the estimated maximum power output of your panels. Viridis Energy uses larger microinverters than our competitors, ensuring you get the most power out of your panels.
  3. Install the microinverters correctly: Each microinverter should be installed according to the manufacturer's instructions and connected to the correct solar panel. Make sure that the wiring and connections are secure and that the microinverters are not located in an area that is likely to be affected by moisture or heat. Viridis Energy is an award winning SunPower installer so you can be rest assured that we have the highest quality installs around!
  4. Monitor the system regularly: Regular monitoring of your solar power system can help you identify any issues early on, including clipping. Use a monitoring system that provides real-time data and alerts you when the output of the panels exceeds the capacity of the microinverters. Use the SunPower mobile app to view your individual panel production in real time to see how each panel is performing.

Another popular way to avoid clipping in a solar power system is by installing a home solar battery.

Home Solar Battery Energy Storage

When a solar power system with battery backup experiences clipping, the excess energy that would normally be lost is instead stored in the battery for later use. This helps to maximize the use of the energy produced by the solar panels and can help to reduce the overall impact of clipping on the system's efficiency.

There are different ways to implement battery backup in a solar power system, but one common approach is to use a battery management system that automatically directs the excess energy from the panels into the battery when the inverter reaches its maximum power capacity. This ensures that the battery is only charged when there is excess energy available, and that the energy stored in the battery is used when the panels are not producing enough power, such as at night or on cloudy days.

By integrating a battery backup system into your solar power system, you can help to avoid the losses associated with clipping and increase the overall efficiency of your system. Additionally, a battery backup system can provide you with backup power during power outages, making it a valuable investment for homes and businesses in areas with unreliable electrical grids.

By following these steps, you can help to ensure that your microinverter-based solar power system operates efficiently and avoids clipping. Additionally, having a well-maintained and monitored system can help to extend its lifespan and maximize your return on investment.

In conclusion, clipping is an important consideration when installing a solar power system. By properly sizing the inverter and avoiding clipping, you can maximize the efficiency and lifespan of your system and ensure that you are getting the most out of your investment.

Be weary of those other shady solar companies. Most of our competitors will give you quotes for a similar sized solar panel but will cheap out on the microinverters (they won't tell you that). By using the smaller and cheaper microinverters on your solar panels you will be clipping power and losing efficiency.

Viridis Energy installs the larger and properly sized microinverters on our SunPower systems so you'll never have to worry about efficiency issues.
