Case study: Solar + Tesla Powerwall in Franklin, TN

Last fall Dana and Brent Kose of Franklin, Tennessee, watched excitedly as LightWave turned on their solar + Tesla Powerwall system. Immediately, their home began to rely less on the grid and more on the sun.

Brent and Dana now have much more visibility into their home’s energy use. On Tesla’s mobile app, they can see exactly how much energy they use, when they use it and where it comes from – solar, batteries or the grid.

Their home features a 12-kilowatt solar system and three Tesla Powerwall batteries. Like many households, their usage is relatively low when the sun is at its peak, and it increases around dinnertime. Batteries store excess solar energy and cover nearly all of their nighttime use.

“It’s a good thing we have the batteries,” says Dana Kose. “Otherwise, we would lose about half of our solar energy and have to send it to the grid for free,” she says.

Since the system was installed in November, the Koses’ monthly electric bills have dropped by 65% on average. That’s despite the fact that December, January and February had over 20% less sunlight than average.

Even still, during the last two months, Dana and Brent’s solar and battery system covered just over half of their home’s electricity use including two electric cars! Not only will their system’s performance improve as the days get longer and sunnier, but also as they learn more about their consumption.

“Now we’re more conscious of when we charge our cars,” says Dana. “Recently on a sunny day Brent said, ‘We’re exporting, go charge the car!’ He checks the app nearly every day,” she says.

LightWave Solar could only place the solar panels on the back of the home, which faces east and slightly south, to accommodate HOA restrictions on the front of house. Dana says she would have loved to have had them installed on the south-facing side for optimal solar production.

“I wish the system was more visible so more of our neighbors could see it and ask about it,” she says. “We highly recommend the system and LightWave,” she adds.

Dana works in commercial energy efficiency, and her reasons for installing solar and batteries go beyond innovative technology, bill savings and backup power during grid outages. Her primary goal is to generate cleaner energy to reduce her home’s impact on the environment.

“I’m passionate about keeping our environment as clean as possible, so my kids and future generations can live in the same or better conditions than we do today,” Dana explains.

We had a great experience with Lightwave. They installed an add on system of 5kW along with a Tesla Powerwall battery. From the initial presentation to the final project completion, they all worked together and everyone on their team seemed truly happy to be engaged in this new industry. They are true professionals and I was glad we selected them. In addition to having a high tech back up system for my home, I am now off grid about 30% of the time. Amazing.

Light Wave Solar is terrific. All their people were great to work with, knowledgeable and on- the- ball. They were everything i could have asked for and i couldn't be happier with the system they installed. So far it is working just as i hoped!

I needed LightWave's help after a wind storm caused a tree to fall on my house. The tree destroyed ten solar panels on my roof. LightWave's technicians visited me to assess the damage and plan repairs. LightWave's project manager took over from that point. After the design was complete and approved, the installation crew completed the job in a single day. Every LightWave representative was pleasant and professional. I would recommend them to anyone who needs their services.

The entire team at LightWave Solar went above and beyond to ensure that our solar install was done on time, on budget, and to our satisfaction. Professional in every way. I can't get over how seamlessly they have integrated everything to our 1960 built home. Very well done. An added bonus is their handling of the necessary licenses, myriad forms and paperwork and approvals from local power company and TVA. These guys deserve 10 stars!

We installed a 10 KW solar panel array on the roof of our home this past fall. The process required coordination between us (the customer), the local electric company (Nashville Electric Service) and the Tennessee Valley Authority (TVA). While this may seem daunting, it turns out that apart from signing a few routine documents, the process requires little to no effort on the part of the customer: Lightwave Solar takes care of all the details. Their attention to those details was impressive, which meant the whole operation was smooth, professional and basically worry free. The physical installation itself is a marvel of craftsmanship and technology. Lightwave Solar fully earns their five star rating and I recommend them without reservation.

My first month's savings was over $100. This is in spite of shorter fall days, cloudy days, and rain. The shortest day of the year is in late December. Its best performance will be in the spring and summer. I am very pleased with it.
