SepiSolar engineers are at the forefront of solar energy storage including battery design, technologies, codes, utility policies, and permitting. Whether you’re installing solar energy storage for the first time or have years of experience, SepiSolar can support your solar energy storage project with a full suite of design and engineering services.
Whether lithium or flow batteries, grid-tied or off-grid, with or without fuel-based generators, SepiSolar offers complete permit-ready solar energy storage design packages and consulting services for your storage project.
Solar Energy Storage Permit Packages
SepiSolar designs and engineers solar energy storage systems that are tailored to your specific technology, application, and the requirements of local AHJs and your utility. Complete solar energy storage permit packages typically include:
Mounting & racking methods
Three-line electrical diagram
Required Safety Placards
Other Solar Energy Storage Services
SepiSolar designs solar energy storage systems for residential, commercial, industrial, agricultural, utility, and microgrids. Our services include:
Electrical single-line and three-line diagrams utility and permit processing
Battery storage system sizing and performance modeling
Solar PV-plus-storage system sizing optimization
Storage O&M and battery augmentation schedules
Stand-alone energy storage design for peak shaving, backup, UPS, and emergency applications
Designs for DC- or AC-coupled energy storage systems
Solar energy storage utility interconnection processing
Solar energy storage technology comparisons (e.g., lithium vs. flow batteries vs. flywheel vs. others)
Solar energy storage financial modeling for sales proposals: residential, commercial, industrial, utility
Electrical and structural PE stamps for all 50 states and jurisdictions
Processing for California SGIP and SOMAH solar-plus-storage applications
Solar-Plus-Storage Modeling Services
SepiSolar’s engineers have developed proprietary solar-plus-storage modeling tools for designing cost-effective systems for all solar energy storage applications, demand charge reduction, frequency regulation, spinning reserve, transmission support, and other applications.

Solar Energy Storage Technologies
SepiSolar engineers are solar energy storage technology and chemistry agnostic. We design solar-plus-storage systems for all battery chemistries and brands, including:
Lithium (Li-ION, LFP, NMC, NCA, etc.), including Tesla, Sonnen, LG, Panasonic’s Pika Energy, Sony, Enphase, StorEDGE, SimpliPhi, etc.
“Hybrid” flow batteries (zinc-bromine, iron-iron, zinc-iron, etc.): ESS, Primus, etc.
Lead acid (advanced, traditional, etc.)
Flywheel (Amber Kinetics)
Other proprietary storage technologies
Using SepiSolar for designing and engineering Swell Energy’s solar-plus-storage systems was a no-brainer. Storage is complicated, so we wanted to work with a team of U.S.-based quality engineers who could speak ‘fluent solar energy storage’ and get out accurate plan sets quickly and with minimal AHJ revisions. If you’re looking for a quality design partner who knows how to get storage permit plans approved in California, trust the SepiSolar team.”
