You’re Leaving Money on the Table Post-PTO

You’re Leaving Money on the Table Post-PTO

by · Published on

When I started a solar installation business in 2016, the only thing we sold was solar panels.

When I sold a solar installation business in 2024, the only things we sold were solar panels, battery energy storage, whole-home consumption monitoring, circuit-level consumption monitoring, electric vehicle chargers, load control, critter guards, service plans, aesthetic skirts, and snow guards.

Big difference, huh?

Now, consider this: if your company also sells most or all of these items, you almost certainly have more money left on the table with your solar-only customers than you’ve earned in revenue to date.

If you sold a $25k solar system and have $25k in untapped upgrades (like battery storage, EV charging, or service plans) on that project, what are you doing to make the post-PTO sale?

That’s why you need an eShop in your own branded app.

No need for dedicated marketing to upsell your existing customers—Sunvoy can do it for you, automatically.

Your customers will see the eShop in their app every time they check:

  • Their project status
  • Consolidated energy monitoring
  • Referral statuses
  • Project documents
  • Service tickets
  • Or even when they post a review

The construction industry is notoriously bad at:

  1. Showcasing all available products and services.
  2. Upselling items that add tremendous value to customers.
  3. Maximizing the lifetime value of their customers.

That’s why Sunvoy Protect is now available as an optional product in the eShop of every Sunvoy customer.

Imagine being able to sell your own custom service plan! You can highlight warranty lengths for:

  • Your in-house workmanship warranty
  • Manufacturer warranties
  • Upgraded service plans (e.g., RMAs, active monitoring, etc.)

Interestingly, there’s no plug-and-play eShop option in the solar industry. At our solar installation business, we had to custom-build one from scratch. However, it didn’t come close to the visibility of an eShop that’s native to a branded app and customer portal.

A goal for all solar installers should be to double the revenue earned from an initial solar-only sale over the lifetime of the customer.

Sounds hard, right? It doesn’t have to be.

Example of Lifetime Revenue Growth:

  • Initial sale: 10kW solar-only system: $25k
  • Year 1: Service plan at $0.10/Watt: $1,000
  • Year 2: Energy storage: $20k
  • Year 3: Aesthetic skirt: $1,000
  • Year 4: Snow guard: $1,000
  • Year 5: Squirrel guard: $1,000
  • Year 6: EV charger: $2,500

Total in 6 years: $26,500

Does that sound plausible? It should—because it’s common for homeowners to delay these purchases upfront, or for salespeople to overlook them altogether.

If you’re a solar executive, you’re probably also a solar homeowner. You already know:

  • Squirrels can wreak havoc.
  • Snow sliding off modules can damage cars.
  • Blackouts make energy storage a necessity.
  • More people are trading gas cars for EVs.

The question is: what are you doing today to make it easy and obvious for your customers to add these upgrades to their systems?

Your Options:

  1. Dedicate part of your marketing team to upselling existing customers (but new customers keep the lights on, right?).
  2. Build an eShop from scratch with developers (how long will that take and at what cost?).
  3. Send automated emails reminding customers of your offerings (but will they convert?).

Or...

Have an eShop in your branded app that your customers already use daily for energy monitoring, documents, and service tickets. It’s the best way to turn your app and portal into a value-adding flywheel, helping your customers fully electrify their homes and lives.

Final Thoughts

Think about the opportunity here: an eShop in your branded app doesn’t just increase your revenue—it creates a better experience for your customers. It allows them to feel informed, empowered, and supported throughout their solar journey.

At the end of the day, your customers are likely already considering these upgrades, even if they don’t know where to start or who to trust. By offering these products in an easy-to-access eShop, you’re not just upselling—you’re helping them maximize the value of their solar investment while building loyalty that lasts for years.
