Solar Panels, Inverters and EMF Radiation? Here's What You Need to Know

Posted by Security Team on

As solar energy gains popularity, some people have raised concerns about potential electromagnetic field (EMF) radiation from solar panel systems. While solar panels themselves emit very low levels of EMF, the inverters and wiring connecting the panels to your home can be sources of low-frequency EMF radiation. In this in-depth article, we'll explore why solar components may produce EMF, how to measure radiation levels, and effective ways to reduce your exposure.


Understanding EMF Radiation from Solar Inverters and Wiring

The primary sources of EMF radiation in a solar energy system are the inverter and the AC wiring, not the solar panels themselves. Here's a closer look at why:

Solar Inverters: Converting DC to AC Power

Solar panels generate direct current (DC) electricity, but most homes and appliances use alternating current (AC). The critical component that makes this conversion possible is the solar inverter. During the DC to AC conversion process, inverters create low-frequency EMF radiation. There are two main types of inverters:

  1. String Inverters: These centralized inverters are connected to multiple solar panels and are often located near the main electrical panel. String inverters tend to emit higher levels of EMF than microinverters.
  2. Microinverters: These smaller inverters are attached directly to individual solar panels, converting DC to AC power at the source. While microinverters may increase the overall EMF radiation across your roof, they can potentially reduce EMF exposure inside your home compared to string inverters, depending on factors such as distance and shielding.

AC Wiring: Carrying EMF-Generating Current

The AC wiring that carries electricity from the inverter to your home and the electrical grid also contributes to low-frequency EMF radiation. The higher the current flowing through the wires, the greater the EMF emissions.

Smart Meters and Wireless Communication

Many modern solar energy systems include "smart" meters and wireless monitoring equipment. These components communicate using radio frequency (RF) signals, adding to the overall EMF radiation produced by the system. It's important to note that while the EMF levels from a properly installed solar array are generally considered low compared to other household sources, improper installation or faulty components could lead to higher than expected radiation levels. The actual EMF levels may vary depending on factors such as the size of the system, the specific components used, and the proximity to living spaces.

Measuring EMF Radiation from Your Solar System

If you're concerned about EMF radiation from your solar panels or inverter, the first step is to measure the EMF levels using a reliable meter. Here's how:

  1. Obtain an EMF meter that can measure both low-frequency (ELF) and radio-frequency (RF) radiation, such as the TriField TF2.
  2. Take baseline readings in various areas of your home before the solar installation to establish a reference point.
  3. After installation, take EMF measurements near the inverter, smart meter, and along the wiring pathways. Compare these readings to your baseline measurements and established safety guidelines.
  4. If the EMF levels are higher than expected, contact your solar installer to check for any issues with the system's components or wiring.

For a more comprehensive assessment, consider hiring a professional EMF inspector to conduct a thorough survey of your home and identify any areas of concern.

Strategies for Reducing EMF Exposure from Solar Systems

If you want to minimize your exposure to EMF radiation from your solar energy system, consider implementing these strategies:

  1. Choose a Low-EMF Inverter: When selecting an inverter for your solar array, opt for models with lower EMF emissions. Some manufacturers, like SolarEdge and SMA, offer inverters with reduced electromagnetic interference (EMI).
  2. Opt for Microinverters: If possible, choose a solar panel system with microinverters rather than a centralized string inverter. While microinverters may increase the overall EMF levels across your roof, they can potentially reduce EMF exposure inside your home, depending on factors such as distance and shielding.
  3. Locate the Inverter Away from Living Spaces: If using a string inverter, work with your installer to position it as far away from frequently occupied areas as possible, such as bedrooms, home offices, and living rooms.
  4. Use Shielded Wiring: Ensure your solar installer uses shielded cables to carry power from the panels to the inverter and from the inverter to your home's electrical panel. Shielded wiring can help reduce EMF emissions.
  5. Consider EMF Shielding Materials: In some cases, you may want to use EMF shielding materials to create a barrier between the inverter or wiring and your living spaces. Options include EMF shielding paint, fabrics, and films.
  6. Install Dirty Electricity Filters: Solar inverters can generate high-frequency voltage transients, known as "dirty electricity," on your home's wiring. Installing dirty electricity filters, like the Stetzerizer or Greenwave filters, can help reduce these emissions.
  7. Minimize Wireless Communication: If possible, opt for a solar monitoring system that uses wired connections rather than wireless communication to reduce RF radiation exposure.
