Behold The Future…SolPad Welcome to the future of the sustainable connected home.

SolPad gives you the ability to experience true energy independence with total control of your power.
SolPad uses future-forward design paired with a disruptive level of system integration. With this approach, SolPad reduces the installed cost of solar power with battery storage by up to 50% when compared to other available solar products.

SolPad is creating and defining a new sustainable energy future that will help clean up our environment and make the power of the sun accessible to everyone.

SolPad Home™ is the ultimate sustainable energy solution for powering an entire home with clean solar power. It offers homeowners an unprecedented level of control over their electricity generation, energy storage and usage. While SolPad Home is designed to be a gorgeous rooftop solar solution, it is much more than just a solar panel.

Each SolPad Home panel is like a smart-energy computer on your roof, with each device being its own energy powerhouse that is completely self-sufficient. Homeowners can start with one SolPad and easily add more with minimal installation time.

SolPad Home panels store both solar and grid energy with forthcoming solid-state battery technology. This battery technology is inherently safer than standard lithium-ion-based batteries. They have a broader operating temperature range and longer life. Each SolPad device is equipped with its own “solar micro-storage,” or built-in battery storage at the panel level, and the solid-state low-voltage battery design is optimized for safe rooftop operation.

SolPad’s Home’s flexgrid™ inverter has a truly unique and intelligent design that is flexible enough to account for the many different power environments that exist in today’s world. The flexgrid inverter is designed to seamlessly integrate with built-in solid-state “solar micro-storage,” and this innovative combination allows SolPad to operate with electrically optimized power efficiency.

SolPad’s flexgrid inverter can automatically detect when to charge from the sun or charge from the local utility grid, adjusting for cloudy or rainy days, as well as changing local electricity rates. During the most expensive daytime hours, SolPad Home will switch to stored battery power, then switch back to grid power when rates are low. Flexgrid will also detect when there’s a power outage or blackout and safely disconnect itself from the grid. Once off the grid, SolPad automatically forms a personal solar micro-grid that will keep delivering power to specific lights and appliances. The SolPad Home Connect™ system is the most innovative power delivery interface to get power from your roof into your home. Connect is a wire-free system that links two or more SolPad Home panels together on your roof, completely eliminating the need for any complicated cabling or wiring, simplifying the installation and greatly reducing cost and installation time.

SolPad Home combines solar and smart home components that have traditionally always been bought and installed separately. Due to this integration and elimination of parts, SolPad’s fully integrated product design approach reduces the total cost of installed solar and energy storage by up to 50% when compared with other existing product offerings.

“Labor and technical soft costs are the hardest problems to solve when it comes to integrating solar and storage with software. SolPad did an amazing job of inventing new technologies and packaging them in a way that is both consumer and installer friendly,” said Barry Cinnamon, CEO of Spice Solar and a longtime solar industry installer.
