Electrical System Upgrade

Electrical System Upgrade

Is Your Electrical Panel Ready for Solar?

Solar panels generate power.
Your electrical panel distributes it.


If your main service panel is outdated or undersized, it may not safely support a solar panel installation or battery system.


That’s where we come in.


At Express Connection, we specialize in electrical panel upgrades in Fresno, CA designed specifically for the renewable energy industry. We make sure your home or commercial property can safely handle increased electrical capacity while staying fully code compliant.


Why Electrical System Upgrades Matter for Solar

Many homes in Fresno and surrounding areas were built decades ago with 100-amp panels. Modern energy demands — especially with solar, battery storage, and EV charging — often require 200-amp service or higher.


An upgraded electrical system allows you to:

  • Safely integrate a new solar energy system
  • Add battery storage without overloading circuits
  • Prevent breaker trips and overheating
  • Meet California electrical code requirements
  • Increase long-term property value

If your panel can’t handle the load, your solar savings could be limited before you even start.

Frequently Asked Questions

How do I know if I need an electrical panel upgrade for solar?

If your home has a 100-amp service panel or an older breaker box, you may need an upgrade before installing solar panels. We evaluate your existing system to determine whether a panel upgrade is required for safe solar integration.

Can I install solar without upgrading my panel?

In some cases, yes. However, many homes in Fresno require a panel upgrade to meet electrical code requirements and safely handle the added power generation from a solar energy system.

How long does an electrical panel upgrade take?

Most main panel upgrades can be completed within one day, depending on the scope of work and inspection requirements.

Will upgrading my panel increase my home value?

Yes. A modern electrical panel improves safety, increases capacity for future upgrades, and adds value — especially for buyers interested in solar, battery storage, or EV charging.

Do you handle permits and inspections?

Yes. We manage permitting and coordinate inspections to ensure your electrical system upgrade complies with Fresno County and California electrical standards.
