Battery & Energy Storage

What it does Solar panels convert sunlight directly into clean electricity. That power flows through your inverter to run your home in real time, charge your battery, fuel your EV, and — when you're producing more than you need — export back to the grid for credits.

Standalone benefits

• Lower (or eliminate) your power bill. Every kilowatt-hour your panels produce is one you don't buy from the utility. For many homes, that's the difference between a three-figure monthly bill and almost nothing.

• Lock in your energy cost. Utility rates only go one direction. Rocky Mountain Power has a long history of aggressive rate increases, and every approved hike makes the power you don't own more expensive. Solar fixes a large portion of your energy cost for 25+ years.

• Earn credits for what you send back. Under net billing, the excess energy your system produces during the day earns export credits that offset what you pull at night.

• Increase your home's value. Owned solar is a permanent home improvement that buyers increasingly expect — especially in the high-end market.

• Clean, quiet, and maintenance-light. No moving parts, no fuel, no noise. Panels simply work whenever the sun is up.

Better with the EcoSystem On its own, solar can only help you while the sun is shining and the grid is up. Inside the EcoSystem, solar becomes the engine that fuels everything else:

• It charges your battery during the day so you can use that energy after dark.

• It runs your loads through the smart panel, which decides in real time whether to use solar directly, store it, or export it.

• It powers your EV so you're driving on energy you produced for free.

• It reduces how often the generator ever has to run, because your battery is being topped off all day long.

Solar is the foundation. Every other product multiplies what it can do.

What it does A home battery stores the electricity your solar produces (or that you pull from the grid) so you can use it later — at night, during peak-rate hours, or when the grid goes down. The moment the utility fails, the battery seamlessly takes over, usually fast enough that you never notice the lights flicker.

Standalone benefits

• Keep the power on during outages. When the grid drops, your battery keeps your essentials — or your whole home — running automatically and silently. No cords, no fuel, no manual switching.

• Use your own energy when it's most expensive. Instead of buying power from the utility during high-cost peak windows, you draw from energy you already stored. This is especially powerful on time-of-use rate plans.

• Energy independence. A battery shifts you from being fully dependent on the grid to having your own reserve you control.

• Silent and clean. Unlike a generator, there's no engine, no fumes, no noise — just instant, quiet backup.

• Protects sensitive equipment. Clean, stable battery power is gentler on electronics and appliances than the surges and dips that can come with grid disturbances.

Better with the EcoSystem A battery alone is only as good as what's charging it and what's managing it. Inside the EcoSystem:

• Solar refills it every day, so you're not just storing grid power — you're banking free, clean energy and waking up to a full reserve.

• The smart panel makes it last longer, intelligently shedding non-essential circuits during an outage so your stored energy goes to the things that matter most.

• The generator backs it up during multi-day outages or cloudy winter stretches, so your battery never gets stranded empty.

• It enables managed EV charging, letting you charge your car from stored solar instead of the grid.

The battery is where independence becomes real — but the smart panel and solar are what make it stretch.

What it does A smart electrical panel (like Span) replaces or supplements your traditional breaker box with intelligence. It monitors every circuit individually, lets you control them from an app, and automatically orchestrates how solar, battery, grid, and generator power your home. Think of it as the operating system for your energy.

Standalone benefits

• See exactly where your energy goes. Circuit-level monitoring shows you in real time what every part of your home is using — no more guessing what's driving the bill.

• Control your home from your phone. Turn circuits on or off remotely, set schedules, and manage your energy from anywhere.

• Prevent overloads intelligently. The panel can manage high-draw loads (like an EV charger or HVAC) so they don't trip breakers or force a costly service upgrade.

• Smarter, safer wiring. A clean, app-managed panel modernizes the heart of your electrical system.

Better with the EcoSystem This is where the smart panel truly earns its place — it's the conductor that makes every other product work together:

• During an outage, it decides what stays on. Instead of your battery trying to power everything at once and draining in an hour, the panel prioritizes essentials and can keep critical circuits running for days.

• It optimizes solar and battery use automatically, choosing whether to use power now, store it, or export it based on your settings and rates.

• It manages EV charging around the rest of your home's demand, so charging your car never overloads your service.

• It coordinates the generator handoff, so the transition between battery and generator is seamless.

Without a smart panel, you have a collection of products. With one, you have a system — automated, optimized, and controllable from a single screen.

What it does A Level 2 home EV charger delivers fast, convenient charging right in your garage or driveway — far quicker than a standard wall outlet. Integrated into the EcoSystem, it charges intelligently, drawing from solar and battery and coordinating with your smart panel to avoid overloading your home.

Standalone benefits

• Wake up full every morning. Plug in overnight and start each day with a full battery — no detours to a public charger, no waiting.

• Charge faster. A Level 2 charger adds many times the range per hour compared to a standard outlet.

• Drive cheaper than gas. Charging at home is dramatically less expensive per mile than filling a tank, and far more predictable.

• Schedule for savings. Set charging for off-peak hours to take advantage of lower rates.

Better with the EcoSystem Charging an EV is one of the biggest loads you can add to a home — which is exactly why it benefits most from the full system:

• Charge on sunshine. With solar, you can fuel your car with energy you produced rather than power you bought.

• No expensive service upgrade. The smart panel manages charging around your home's other demands, often letting you add an EV charger without upsizing your electrical service.

• Charge from your battery when it makes sense, drawing on stored solar instead of the grid.

• Keep charging optimized automatically, so your car fills up at the cheapest, cleanest times without you thinking about it.

An EV charger is convenient on its own. Inside the EcoSystem, it's nearly free to run and effortless to manage.

What it does A standby generator is the deepest layer of backup in the EcoSystem. When an outage runs long — or when solar production is low for days and your battery is running down — the generator starts automatically to recharge the battery and keep your home powered. It's the insurance policy behind your insurance policy.

Standalone benefits

• Power through extended outages. A generator can run for as long as it has fuel, covering multi-day outages that would eventually drain a battery alone.

• Whole-home backup capacity. Properly sized, a generator can carry heavy loads that a battery might not sustain for long stretches.

• Proven, fuel-based reliability. When weather knocks out the grid for days, a generator keeps going regardless of sun or season.

• Automatic operation. Modern standby generators start on their own — no hauling out a portable unit or running extension cords.

Better with the EcoSystem A generator on its own is loud, runs constantly, and burns a lot of fuel. Inside the EcoSystem, it becomes a smart, last-resort backstop that rarely has to run at all:

• It only kicks on when truly needed. Solar and battery handle the day-to-day; the generator stays off until the battery actually needs help — so it uses far less fuel and runs far less often.

• It recharges your battery, then shuts back off, instead of running nonstop. This is dramatically quieter and more efficient than a traditional generator setup.

• The inverter/ATS and smart panel handle the handoff automatically, so the transition in and out of generator power is seamless.

• It covers the worst-case winter scenario — short days, heavy snow on panels, long outage — so you're never left without power, no matter what.

The generator is optional because the rest of the EcoSystem already handles the vast majority of situations. But for total, no-exceptions resilience, it's the final piece.
