How Bakertech Helped a Florida Homeowner Avoid a Costly Electrical Service Upgrade When Adding Solar + EV Charger

Key Insights

Adding solar panels without factoring in additional high-demand appliances like EV chargers, pool heat pumps, or tankless water heaters can lead to service overload and failed inspections.
Most failed inspections stem from the absence of proper load calculations required by NEC articles 220, 230.23, and 230.31.
A solar PV system may offset energy consumption, but it does not reduce the home’s power requirements, especially at night or under low-production conditions.

A Florida homeowner was ready to embrace clean energy by installing solar panels, an EV charger, and a new electric tankless water heater—all within the same home improvement project. The solar company, however, failed to include a load calculation or verify the home's electrical service capacity before installing the add-ons.

What Bakertech Did

Bakertech stepped in to perform a comprehensive load calculation in compliance with NEC 220.83 and 230.31, and identified that the combined power draw of the new devices would exceed the home’s existing 200A electrical service. Without intervention, this would have triggered the need for a 400A service upgrade, including a costly utility transformer replacement.

By reviewing the full load scenario before installation, Bakertech was able to:

  • Recommend a right-sized solar PV system that factored in the future EV charging and heating needs.
  • Save the homeowner thousands of dollars in unnecessary utility upgrades.
  • Ensure a seamless AHJ inspection by having all NEC-compliant documentation ready in advance.

Outcome

Thanks to Bakertech’s intervention, the homeowner:

  • Avoided a failed inspection and costly service upgrade.
  • Installed a compliant and performance-optimized solar system.
  • Gained confidence knowing their new system met both energy and power requirements.
