Store what you produce, use it when it counts
Why choose Helios?
Solar panels produce energy during the day, but your home needs power around the clock. Battery storage bridges that gap - storing what you generate and releasing it when you need it most.
What you pay
Evening and overnight electricity comes entirely from the grid. That's 10–14 hours of consumption every day at whatever rate the utility sets.
When you use it
Peak consumption happens after sunset - cooking, entertainment, HVAC, devices. That's exactly when solar production drops to zero and grid rates spike.
What you control
Without storage, excess daytime solar goes back to the grid at a discount. You buy it back later at full price. The math works against you every evening.
"We went from $312 to $108 in our first full billing cycle. The system paid for itself faster than we expected."

Energy doesn’t get expensive overnight
Power outages don't send a warning. Neither do rate spikes. Battery storage gives your home the ability to keep running on its own terms — quietly, automatically, and without depending on a grid that wasn't built for today's demands.
Limited independence
Without storage, your home goes dark the moment the grid does.
Static setup
Solar exports by day, you buy it back at full price by night.
Hidden inefficiencies
Every kWh exported cheap and repurchased expensive is money lost.
Inflexible adjustments
Grid-dependent homes can't shift when they use power.
