Solar sales slowing? Home batteries are the next big thing
Let’s face it—solar panel installations aren’t as booming as they used to be. Feed-in tariffs are dropping, grid limitations are increasing, and customers are becoming more cautious with new investments.
But here’s the opportunity: home batteries are quickly becoming the next must-have. People want energy independence, backup during outages, and lower electricity bills—and batteries tick all the boxes.
The challenge? Most installers don’t know how to find high-quality leads for battery installations.
The good news? You’re sitting on a goldmine. Your PV-Designer tool, the same one you use for solar, can help you scout ideal prospects, calculate battery ROI, and send compelling offers—without spending a cent on ads or lead lists.
In this blog, I’ll show you how to turn your PV-Designer into a full-blown lead engine for home batteries. It’s a simple, scalable strategy your team can start using today.
How to identify solar-equipped homes for battery upsell
Do you want to find high-quality battery installation leads? Start with your PV-Designer tool. If you don’t have one yet, check out our blog on the top 6 solar proposal software tools and pick the one that best fits your needs.
Here’s how to identify battery-ready homes:
Pick your service region and assign territories to your sales team.
Use the PV tool to visually inspect rooftops and spot homes with existing solar panels.
Recreate the solar installation using your PV-Designer to estimate annual or monthly kWh generation.
These homes have already invested in solar and are much more likely to be interested in battery storage. The kWh data you generate is your foundation for making an ROI case.
How do you calculate the ROI of a home battery
To build a compelling home battery proposal, you need the right data. Here's how to calculate return on investment:
Estimated solar generation: Use your PV-Designer to get this.
Consumption pattern: Estimate how much energy is self-consumed versus exported to the grid. Use housing-type averages or assume a baseline (e.g., 30% consumed, 70% exported).
Excess/exported energy: This is your battery opportunity. For example, if 70% is exported, that’s energy that could be stored and used later.
Battery specifications: Know your batteries. Compare capacity (kWh), round-trip efficiency, and power output.
Sample calculation:
Annual solar generation: 6,000 kWh
Exported to grid: 4,000 kWh
Usable via battery (80%): 3,200 kWh/year
Electricity price: €0.30/kWh
Annual savings: €960
Battery system cost: €8,000
ROI: ~8.3 years

How to build and deliver a personalized home battery proposal
Now that you have the math, it's time to present your offer:
Build a professional quote: Include ROI, potential savings, and suggested battery models.
Educate the customer: Add a short explanation of how the battery works and its benefits.
Personalize it: Mention specific findings, like "we noticed your home is exporting a lot of solar..."
Send it by post: A printed offer is more likely to be noticed than an email.
How to prioritize the right homes for outreach
Not every solar home is a strong battery lead. Here’s how to focus your efforts:
Large solar arrays: More panels = more excess energy = more savings.
Low feed-in tariffs: When solar export rates are low, storing energy becomes more attractive.
High electricity costs: In expensive regions, batteries provide higher value and faster payback.
Use this strategy to filter for the most promising prospects.
Is it legal to send printed offers to homeowners?
Yes, in most cases—but be cautious. Here's what to know:
Do:
Keep it general.
Use only public information (e.g. roof images, addresses).
Don't:
Use names or private consumption data without consent.
Mislead or pressure the recipient.
Always check local regulations before running a mail campaign.
Bonus tip: Run targeted ads for battery installations
Boost your outreach by running localized, focused digital ads.
Make your ads count:
Highlight real savings
Include explainer graphics or short videos
Show your actual team or clients
Only target areas where you can install
The more trustworthy you look online, the more likely prospects are to engage.
Conclusion: You don’t need new leads—you just need a new angle
