Choosing the right size electrical panel is one of the most important steps in ensuring your home’s safety and functionality—especially in a growing and tech-forward area like Seattle. Whether you're planning a remodel, adding new appliances, installing a hot tub, or preparing for solar panels or an electric vehicle, your home’s panel needs to handle today’s demand and be ready for what’s coming tomorrow.
At Galaxy Electric & Solar, we've helped Seattle homeowners with thousands of electrical upgrades, and one of the most common services we provide is the electrical panel upgrade Seattle. But before you jump into a panel replacement, it's essential to understand how sizing works and why it matters.
Calculating Current and Future Load Requirements
An electrical panel is the hub that distributes power throughout your home. Choosing the right size starts with understanding how much power your household needs—both now and in the future.
The National Electrical Code (NEC) provides guidelines for calculating load based on square footage, fixed appliances, HVAC systems, and other factors. But here's the thing: many homes in the Seattle area were built decades ago when 100-amp panels were standard. Today, that often isn’t enough.
Modern households rely on high-powered kitchen appliances, HVAC systems, and an increasing number of devices that stay plugged in 24/7. If you’re planning to add a heat pump, finish a basement, or simply want a more resilient electrical setup, you’ll need a panel that supports increased amperage—often 200 amps or more.
Galaxy Electric & Solar performs a thorough load calculation during our initial inspection to help determine the panel size that aligns with both your present setup and your future plans. Our process goes beyond the code to ensure real-world functionality.
Preparing for EVs, Hot Tubs, Solar Panels, and More
Seattle is a city that embraces innovation and sustainability. As more homeowners transition to electric vehicles and clean energy, the demands on residential electrical systems have increased.
Installing an EV charger? That alone can require up to 50 amps of dedicated capacity. Planning for solar panels or a battery backup system? Your panel must be solar-ready, which includes space for inverters and breakers to handle the added flow of energy.
Hot tubs, heated floors, outdoor lighting systems, and even new high-efficiency appliances add strain to older panels. We’ve seen many situations where a new device caused repeated tripping of breakers—an early warning sign that the panel is operating at or above capacity.
That’s why Galaxy Electric & Solar doesn’t just perform panel upgrades—we tailor them to your specific lifestyle. We help you factor in not only today’s needs but what might be around the corner. If your next step is going solar, our team ensures the new panel aligns with future upgrades, avoiding redundant costs and installations.
The Galaxy Electric Panel Sizing Process
Every home is different. At Galaxy Electric & Solar, we treat each project as a custom solution—not a cookie-cutter install. Here’s a glimpse into how we approach an electrical panel upgrade Seattle:
Initial Consultation & Site Assessment
We begin by reviewing your existing electrical setup. This includes evaluating the panel, main service entrance, meter base, and grounding system. We also ask about future plans—EVs, home additions, solar, etc.Load Calculations
Our team uses detailed worksheets that follow NEC guidelines while applying real-world judgment based on your usage patterns. We’ll also check for any code violations or aging components that need updating.Panel Selection
We recommend a panel size that balances your needs with scalability. For many Seattle homes, a 200-amp panel is ideal, but we also install larger panels (e.g., 300-amp or 400-amp) where warranted. We also help with subpanel installations where necessary.Permits and Inspection
We take care of all the necessary permits and coordinate with your local utility and city inspectors. Compliance is never optional—it’s built into every project we do.Same-Day Service, Clean Install
Our crew arrives on time, finishes most panel upgrades the same day, and leaves your home clean and powered up. We stand behind our work with a two-year warranty.24/7 Support and Monitoring
If you ever experience issues, our team is just a call away. We even offer system monitoring tools to help track power usage and identify opportunities to save energy.
Why Bigger Isn’t Always Better—But Sometimes It Is
It’s tempting to assume that upgrading to the biggest panel available is the smartest move—but that’s not always the case. Oversizing without cause can lead to unnecessary expenses, particularly when upgrades to service equipment or utility infrastructure are involved.
That said, future-proofing is very real. If you’re planning significant additions—like a rental unit, a backyard studio, or whole-home electrification—installing a 300-amp panel now can save time and money in the long run.
We don’t upsell. Our focus is finding the right solution for your home’s needs, based on transparent information and practical planning. That’s why homeowners across Seattle and Shoreline trust Galaxy Electric & Solar for panel upgrades and full-service electrical support.
