Capacity Without Construction
Batteries give your solar the capacity to save energy for the hours your utility charges the most. Yotta's batteries go right under your solar panels and are installed along with them, so there's nothing else to build.Yotta is pioneering a smarter approach to battery storage for commercial solar with innovative, proprietary technology.Each 1 kWh Yotta Block seamlessly replaces a traditional ballast block in the solar racking system, giving commercial buildings powerful energy capacity without additional construction.
What Installation Means for Your Building
Battery Storage Stops Being a Second Project
Yotta Energy’s solution maximizes cost savings by generating, storing and optimizing energy at the point of demand, with less disruption and more budget certainty than conventional solutions. Every Yotta Block is designed and made in Austin, Texas.
- 01Install Racking as Usual*Standard ballasted racking on a flat commercial roof.
- 02Swap Ballast Blocks for Yotta BlocksEach Yotta Block replaces a ballast block and connects to the DPI.
- 03Commission OnceYotta’s solutions generate savings from day one.
*Yotta deploys anywhere solar can go, including ground mounts and carports. If your project isn’t on a roof, we’d still love to talk about it.
Installer resources
One projectYotta Blocks install with the solar, on the same permit and with the same crew.
142 Yotta Blocks installed under the solar panels on a Southern California grocery store, up and running since September 2026.Timed by the install crew, per Yotta Block, on a grocery store roof in Southern California: a 123 kW solar array with 142 Yotta Blocks, installed in September 2026 and operational in hours, not days.
The Battery Replaces Something Already on Your RoofThe Battery Is the Ballast
Two components do all the work, and both are installed with your solar panels.The Yotta Block replaces a standard ballast block one for one, so the racking layout, the roof load and the crew all stay the same. It pairs with the Dual Power Inverter as one DC-coupled system.

Every Yotta Block, Watched Around the Clock
Yotta Vision is the energy management system that pairs with the Yotta Block. It actively monitors more than 100 data points on every battery to keep the system performing at its peak, and it gives you a direct line to our Austin-based support team.Yotta Vision is the energy management system that pairs with the Yotta Block.

Engineered to Thrive on the Roof
Every Yotta Block is small, sealed and low voltage, and it has passed the industry’s toughest battery fire testing. That’s why it can sit safely under your solar panels.Small, sealed, under 60 V DC and certified to UL 9540. It is the data an AHJ asks to see, and it is why your PV crew can install it without a high-voltage license.
UL 9540 CertifiedSame Project. Ten Years. $110,000 Less.
A cabinet quote comes in $205,000 lower on equipment. Once it is placed, permitted and maintained for ten years, it costs your building $110,000 more than Yotta.The cabinet bid is $205,000 lower on equipment. The full project comes in $110,000 higher, because everything it takes to put a cabinet on the ground comes with it.
A storage quote is one number. Owning a storage system is nine. The eight the quote leaves out are what your building ends up paying for.Clients compare equipment quotes. Show them the full project cost and the higher line item becomes the lower bid.
The Storage Line Item That Doesn't Blow Up Your Schedule or Budget
Everything you need to scope, bid and install a Yotta project.
EMSUse More of the Solar You Already Make
At midday your solar panels often produce more than the building uses. Yotta Blocks store that extra energy under the solar panels and release it into the building later in the day, so you buy less power from the utility. It pays off most where your utility pays you less for extra solar you send back to the grid than it charges you for power.
Engineering Support From Bid Through Commissioning
The risk on a storage line item isn’t the hardware. It’s a plan-check comment, a submittal gap, or a crew standing on a roof with a question and a schedule. Yotta support is led by engineers who have built these systems.
- 01Bidding
You’re bidding and the storage scope is the part you can’t price with confidence.
Send the site address. We come back with a bill of materials and budgetary estimate for your proposal.
- 02Plan Check
Plan check comes back with questions about a battery on the roof.
We help you answer the AHJ with the UL 9540 certification and the details of the sub-60 V architecture.
- 03Commissioning
Commissioning day, crew on the roof, something doesn’t come up.
Yotta Vision shows our engineers the same telemetry you are looking at, so the call is diagnostic instead of descriptive.
- 04After Install
Two years later the customer calls you about a performance question.
Send it to us. Performance and warranty questions sit with Yotta.
