Your electrical panel is the heart of your home’s electrical system. The breakers inside the panel control the power distributed to each circuit. In Santa Cruz County, CA, summer heat can lead to increased electrical demand as homeowners rely more heavily on air conditioning and other equipment. For some homes, that increased demand may highlight the need to upgrade the electrical infrastructure. If you’re considering an upgrade, the cost to upgrade an electrical panel is likely one of your first questions.
At Infinium Solar, Roofing, and Electric, we want to help you understand how your electrical panel works, when an upgrade may be necessary, and what factors affect the cost. Below, we’ll cover the key details, including what can influence the electrical panel upgrade cost for your home.
Signs Your Panel Can’t Keep Up With Summer Demand
Many electrical panels handle increased summer demand without a problem. Others, however, may struggle as air conditioning and other appliances increase electricity usage. Electrical problems don’t always appear without warning. In many cases, you’ll notice signs that your panel is struggling to keep up with your home’s electrical load.
Many homes in the Bay Area are older and may still have their original electrical panels. If your home has a 100-amp panel rather than a 200-amp panel, you may have less capacity to support additional electrical demand. Modern AC systems and other high-demand equipment can place considerable strain on an older electrical system. Recognizing the warning signs of an overloaded or aging panel can help you determine when it’s time for a professional evaluation.
- Frequent breaker trips
- Dimming or flickering lights
- Warm or hot outlets and switches
- Buzzing sounds from the panel
- Burning smells near the panel
- A panel that is more than 25 years old
Why AC, EV Charging & Modern Homes Overload Old Panels
Before considering the cost to upgrade to 200 amps, it helps to understand why older panels can struggle with modern electrical demand. One common reason is limited capacity. Many older homes have 100-amp electrical service, which may not provide enough capacity for today’s combination of high-demand appliances and equipment. Heat pumps, mini-splits, EV chargers, and other modern electrical systems can significantly increase a home’s overall load.
Age and wear can also affect panel performance. Over time, breakers can deteriorate, connections can loosen, and other electrical issues can develop. Consistently operating circuits near their capacity can create additional strain. When comparing a 100-amp vs. 200-amp panel, the right choice ultimately depends on your home’s calculated electrical load and future power needs.
Modern homes can require substantial electrical capacity to safely support lighting, HVAC systems, appliances, EV charging, and everyday electronics. For homes with backup power systems designed to help during Public Safety Power Shutoffs (PSPS), adequate electrical capacity and proper system design are also important considerations.
100 Amp vs. 200 Amp Panel: How Much Capacity You Need
Understanding the difference between a 100-amp vs. 200-amp panel can help you evaluate your home’s electrical needs. An amp, short for “ampere,” is a unit used to measure electrical current. A 100-amp electrical service provides less total capacity than a 200-amp service. That may not have been a concern decades ago, when homes typically had fewer high-demand electrical appliances, but today’s households often require significantly more power.
A 200-amp panel can provide additional capacity for modern appliances and electrical systems, including refrigerators, washers and dryers, HVAC equipment, and EV chargers. If your existing electrical service no longer meets your needs, contacting Infinium Solar, Roofing, and Electric for an electrical panel upgrade can help you determine the appropriate solution for your home.
Within the panel, individual circuits distribute power throughout different areas of the home. Our professional electricians perform detailed load calculations to determine the appropriate service capacity and panel configuration. This helps ensure your electrical system can safely and reliably support your home’s needs.
What an Electrical Panel Upgrade Costs in 2026
Electrical panel upgrade cost can vary considerably depending on the project. A 200-amp panel upgrade is not a one-size-fits-all service, and installation requirements differ from home to home. When electricians from Infinium Solar, Roofing, and Electric assess your property, we evaluate your existing electrical system, current and anticipated power needs, and the condition of the wiring. We also determine what work is required to remove or modify the existing equipment. Depending on the condition and configuration of your system, additional electrical work may be necessary.
Because every property is different, there isn’t one flat price that applies to every electrical panel upgrade. More complex wiring, electrical repairs, service changes, or additional equipment such as EV chargers and surge protection can increase the total project cost. Our licensed electricians evaluate your home and provide a clear estimate based on the work required. You can also take advantage of flexible financing on approved credit to spread the cost over time.
While exact pricing varies by project, we provide estimates based on the specific scope of work. The cost to upgrade to 200 amps depends on your existing electrical system, installation requirements, and any additional improvements needed to safely complete the project.
Panel Upgrade vs. Replacement: Reading the Signs
An electrical panel upgrade and a panel replacement can involve different scopes of work. An upgrade generally refers to increasing the electrical system’s capacity, while a replacement involves removing the existing panel and installing a new one. In some cases, a replacement may be part of a larger service upgrade.
The right solution depends on the condition of your existing equipment, your home’s electrical demand, and whether additional capacity is required. A professional evaluation can determine whether your home needs a panel replacement, a service upgrade, electrical repairs, or a combination of these improvements.
Frequent breaker trips, flickering lights, unusual sounds, or other electrical problems are signs that your system should be inspected. If your existing panel cannot safely support your home’s electrical demand, our electricians can identify the underlying issue and recommend the appropriate solution.
Permits, Utility Coordination, and What to Expect
In addition to considering electrical panel upgrade cost, homeowners should account for permitting, inspections, and utility coordination. Depending on the scope of work and local requirements in Santa Cruz County and the Bay Area, an electrical panel upgrade may require permits and coordination with PG&E. The process can include load calculations, inspections, approvals, and utility scheduling. Infinium Solar, Roofing, and Electric helps coordinate these steps as part of the project.
You can expect a thorough site assessment, a clear explanation of the project timeline, and an effort to minimize disruption to your daily routine. Our electricians maintain a clean work area and communicate with you throughout the process. We complete our work with a focus on safety, code compliance, and quality workmanship.
