You can see exactly where every dollar of your energy bill is going. Most people can't. Holsen Solar installs the Span smart panel and Emporia circuit-level monitoring — the intelligence layer that connects your solar, storage, EV charger, and entire home into one system you actually control.
A traditional breaker panel distributes power passively. It has no idea what's running, what it costs, or what you'd prefer to prioritize. When the grid goes down, you have no control over what stays on. When you add an EV or heat pump, it might require a costly service upgrade.
Span replaces your panel one-for-one — same location, same wiring, same Eaton or Square D breakers — but with a smart computer connected to every circuit. You see every load in real time. You control every circuit from your phone. And when you add new appliances, Span's PowerUp technology manages the load automatically so you don't need a utility service upgrade.
For new construction, Span is the right foundation to build on. Wire it in from the start and your home is ready for solar, storage, EV charging, and whatever comes next — without ever opening the walls again.
Span's PowerUp technology manages your total electrical load automatically — briefly pausing lower-priority circuits when needed. Add an EV charger, heat pump, or induction range without triggering a utility service upgrade that can cost $3,000–$8,000 and take months.
When the grid goes down, traditional panels lock you into the backup circuits you chose at install. Span lets you adjust priorities on the fly from your phone — extend your battery by 40% by shedding low-priority loads, and power what matters most when it matters most.
Solar and storage without a smart panel is like having a high-performance car with no dashboard. Span shows you exactly how your solar is producing, how your battery is charging, and how your home is consuming — all in real time, all in one app.
The Emporia Vue installs directly into your electrical panel using clamp-on CT sensors — no panel replacement, no major disruption. Within hours of installation you'll have a real-time, circuit-by-circuit view of your home's energy consumption.
Monitor up to 16 individual circuits plus your main feeds. The free Emporia app breaks down your usage by minute, hour, and day so you can see exactly which appliances are costing you money — and when. For solar customers, net metering is built right in so you can see production vs. consumption in real time.
Most business owners know demand charges exist. Almost none know exactly what's causing them — or that they can be actively managed. That's where Emporia changes everything.
Most commercial utility bills have two parts: the energy charge (the kWh you actually consumed) and the demand charge (based on your highest 15-minute power draw during the entire billing period).
That peak — even if it only happened once, even if it only lasted 15 minutes — sets your demand charge for the entire month. One grain dryer startup. One compressor kick. One piece of welding equipment spinning up. And you're paying a premium rate all month long.
For manufacturers, agricultural operations, and commercial facilities, demand charges can represent 30–50% of the total electric bill. Most businesses have no idea which equipment is causing the spikes — until Emporia shows them.
Real-time circuit-level dashboard shows every load in your facility — exactly which equipment is running, how many amps it's drawing, and when your demand peaks are occurring. No more guessing what's on your bill.
Set demand thresholds in the Emporia app. The system alerts you before you hit a costly peak — or automatically adjusts connected devices to prevent the spike from happening at all. Stop paying for 15-minute mistakes.
Month-over-month data shows exactly how much your demand charges have dropped. Bring it to your utility, your accountant, or your lender. Real numbers. Real savings. Documented.
Agricultural electrical loads are some of the most unpredictable in any commercial category. A grain dryer starting up, an irrigation pump cycling on, an auger under load — any of these create massive, instantaneous demand spikes that follow you for 30 days on your utility bill.
Emporia makes these events visible for the first time. You'll see exactly when your demand peaks are occurring, which equipment is causing them, and whether staggering your startup sequences could eliminate the spike entirely. Pair with battery storage and you can actively clip peaks before they hit the meter.
For light commercial buildings, small manufacturers, and agricultural shops doing significant electrification — adding EV fleet charging, upgrading HVAC, or bringing on new equipment — Span's PowerUp technology manages the increased load without triggering a utility service upgrade that can cost $10,000 or more and take months.

Discuss Commercial Span →Solar gets you off the utility during the day. Battery storage gets you off the utility at night — and keeps your home or business running when the grid goes down. We install and program the three leading residential and commercial battery systems.
Best for: homeowners who want the most seamless all-in-one solar + storage experience.
Best for: homes adding storage to an existing solar system, or anyone needing higher capacity.
Best for: commercial operations, farms, and anyone needing a cost-effective scalable system.
When the grid goes down, your battery kicks in automatically — usually within milliseconds. Keep your lights, refrigerator, well pump, and medical equipment running. No generator, no fuel, no noise.
Your solar system produces the most power in the middle of the day — when you're not home using it. A battery stores that excess energy and releases it in the evening when demand (and utility rates) are highest.
Commercial and agricultural accounts pay demand charges based on their peak 15-minute usage window each month. Battery storage — paired with Emporia monitoring — lets you actively clip those peaks before they hit the meter.
A battery alone tells you how much charge is left. Pair it with a Span panel and you can redirect that power to your highest-priority circuits on the fly. Add Emporia monitoring and you can see exactly which loads are drawing from your battery at any moment — and adjust before you drain it.
We design storage systems to work as part of a complete energy management stack — not as a standalone box in your garage. That means smarter backup, longer run times, and a faster payback.
Get a Battery Storage Quote →Span lets you choose which circuits get battery power during an outage — and change those priorities from your phone in real time. Extend runtime by shedding low-priority loads automatically.
See exactly how your battery is charging and discharging at the circuit level. Identify which appliances are draining storage fastest and optimize your usage patterns for longer backup windows.
Store what your panels produce at noon. Use it at 7pm when your family gets home and rates are highest. A properly sized battery can eliminate your utility bill entirely for most of the year.
We'll assess your home or business, recommend the right system, and handle permits and installation. One call gets you started.
Most energy monitoring companies are software businesses that mail you a device with instructions. We're licensed master electricians who assess your panel, size the system correctly for your circuits, install it to code, and are available locally when you have questions. The difference between a professional install and a DIY clip-on is accuracy, safety, and an installation that gets the most out of the hardware.
