How long will your battery keep you running?

Enter your usage, tell us about your solar, and pick a battery — we'll estimate how long it backs up your essentials, small appliances, or your whole home. It's an estimate; your free design confirms real runtime.

Runtime shown is battery-only; the solar line adds daily recharge.

Estimates model each profile as a share of your home's average daily use (Essentials ≈ 30%, Small appliances ≈ 55%, Whole home ≈ 100%), against usable battery capacity, with dollar amounts converted at 0.15 $/kWh. Solar recharge uses ~4.1 kWh/day per kW installed (Colorado). Actual runtime depends on weather, your real loads, and how the system is configured, all confirmed in your free custom design.

Two Homes, Two Great Solar Experiences with Solar Wave

We originally found Solar Wave through EnergySage and compared several companies and proposals. They weren’t the cheapest or the most expensive, but Steve and his team stood out because of how thoroughly they explained the system, compared equipment options, answered our questions, and helped us understand exactly what we were purchasing.

What impressed us even more was the service after the installation. Solar Wave continued monitoring our system and actually contacted us when they detected an issue we didn’t even know existed. They came out and took care of it proactively.

When we moved to a new home in 2026, Solar Wave was the first company we called. We still compared other quotes, but once again their pricing, transparency, equipment recommendations, and service made the decision easy. The larger system was installed in a day, communication has remained excellent, and they continue to monitor it and stay in touch.

After two installations, Solar Wave has earned our trust. Five stars without hesitation.

Battery installation

Solar Wave installed battery to backup my solar system. The installation was quite extensive and I was kept in the loop the entire time. I feel the installation was quite well done and so was the explanation

Great experience with Solar Wave

We completed the install of full Enphase system with battery back up. The Solar Wave team was very knowledgeable about our options and helped us design the right system for us. Install went smoothly and the system is producing as advertised.

Excellent Process Start To Finish

Solar Wave designed and installed the solar system for our new house in Louisville CO. Our design goal was Net Zero operation with a battery backup to reduce the impact of any power outage. From start to finish the process was very transparent. In design, consideration was given to the builder’s detailed energy model, and the impact of adjacent trees and buildings. Their modeling suggested we would be very close to the Net Zero goal. The system would offset approximately 90% of our projected energy needs. Three options for the system were presented. They clearly outlined the pros and cons of each with respect to equipment, operation and efficiency.

The installation process and schedule were clearly defined. The crew communicated their individual tasks and schedules, so we knew exactly who was on site, what they were going to do, when they were doing it and what they needed from us. I was particularly impressed with the approach to organizing and installing the exterior equipment. They carefully considered the arrangement of the equipment from both the technical and aesthetic aspects.

To date (April through August) our system has generated 133% of our energy use. We imported 1.7kWh and exported 2.7kWh. I expect that by the end of the first year we will be very close to their design projections and Net Zero operation.

I highly recommend Solar Wave.

Common battery & solar questions.

Generally no — but they can with a battery. In a standard grid-tied system, panels must shut down during an outage to protect utility workers. Pair them with battery backup and your home keeps power when the grid drops.

Yes. A battery stores solar energy so you can use it during expensive peak-rate periods instead of buying from the grid, and it protects you from rising utility rates — on top of providing backup power during outages.

Yes, but you'll need enough battery (and sometimes generator) backup to cover your loads, and some jurisdictions restrict off-grid setups. Most homeowners choose a grid-tied system with battery backup for the best of both.

It depends on capacity and how the system is configured. A Tesla Powerwall 3 can provide whole-home backup, while modular options like the Enphase 5P let you scale capacity to the circuits that matter most to you.

The 30% federal residential credit for batteries ended for systems installed after December 31, 2025. In Colorado, Xcel's Renewable Battery Connect still pays $250 per kW of battery output, up to $5,000, and Denver offers additional rebates — we'll help you determine eligibility.

Modern lithium-iron-phosphate batteries like the Enphase 5P and Tesla Powerwall are built for long, safe service lives and come with strong manufacturer warranties. We'll walk you through the specifics for each option.
