Full Home Battery Back-up & Solar
For this project, we installed a full home solar system paired with a battery backup to ensure uninterrupted power during grid outages. The system is fully integrated with a monitoring app, giving the homeowner complete visibility into their production, usage, and storage in real time. We designed this setup to maximize energy independence, lower utility costs, and provide peace of mind with reliable backup power whenever it's needed.
Full Home Backup
1 Month
I couldn’t be happier with my new solar and battery backup system! Knowing my home stays powered during outages gives me real peace of mind. The app is a game-changer — I can see exactly how much energy I’m producing, using, and storing in real time. Everything was installed perfectly and the entire process was smooth from start to finish!
Rachel Morgan
Even with solar panels I still had a True-up bill!
When we first met with this homeowner, she already had an existing solar system but was still receiving high true-up bills. After inspecting her setup, we discovered that her panels were outdated and not producing enough energy to meet her needs. We designed and installed an additional set of high-efficiency panels to supplement her system, and now she’s generating enough power to drastically lower her utility costs and eliminate those annual surprises.

Even though I already had solar panels, I was still getting a big true-up bill every year. After reaching out to Delta Solar, they quickly figured out what was wrong and helped me fix it. Now my true-up bill is gone, and I’m finally seeing the savings I expected!
Michael Turner
Utility Bill higher than Snoop
When we first spoke with this customer, she was struggling with electric bills reaching over $1,200 a month during the summer. After reviewing her energy usage, we designed and installed a custom solar system tailored to her needs. We were able to reduce her bill by more than half, helping her take control of her energy costs and finally giving her some financial relief.

During the summer, my electric bill would skyrocket to over $1,200 a month, and it was getting harder and harder to keep up. Thankfully, I found Delta Solar! They helped me install a system that dropped my bill by more than half. I finally have peace of mind and extra money back in my pocket!
