Integrated Energy Systems
Solar, battery storage, and EV charging infrastructure combined into a unified, monitored energy system — designed, installed, and commissioned under one contract.
Our Integrated Energy Systems capabilities
Solar + Storage + EV
All three energy assets designed together from the start — solar array sized for total site load including EV, battery sized for demand charge and backup requirements, and EVSE specified for fleet or public charging needs.
Unified Controls & Monitoring
Single energy management platform showing solar production, battery state of charge, EV charging sessions, grid import/export, and bill impact — one dashboard instead of three separate systems.
Resilience & Backup
Integrated systems designed for islanding capability during grid outages — solar charges the battery during the day, battery powers critical loads at night, and EV charging is managed to preserve backup capacity.
Ideal for these applications
Sustainability-Driven Commercial
Companies with carbon reduction targets benefit from integrated systems that demonstrably reduce grid electricity consumption and Scope 2 emissions.
Fleet Electrification with Renewables
Fleets transitioning to electric vehicles and committing to renewable energy can achieve both goals with integrated depot solar+storage+EVSE.
Resilience-Critical Facilities
Essential services, emergency response, and critical infrastructure require energy resilience that no single technology provides alone — combined systems are the answer.
Commercial Real Estate
Property owners differentiating their assets through energy performance, tenant sustainability, and EV amenities — increasingly a competitive necessity in commercial leasing.
Our integrated energy systems process
Integrated Feasibility Study
Combined load analysis, solar resource assessment, battery sizing, EV load projection, utility rate analysis, and integrated pro forma — delivered as a single document with a go/no-go recommendation.
Design & Permitting
All systems designed simultaneously with a unified single-line diagram. Permits and utility interconnection applications filed together to reduce total approval time.
Construction
Civil work, electrical infrastructure, solar installation, battery installation, and EVSE installation sequenced to minimize downtime and coordinate utility inspection milestones.
Commissioning & Monitoring
All systems commissioned together with integrated controls configured, monitoring platform activated, and performance guarantee baseline established.
Frequently asked
Is it more expensive to install all three systems together versus separately?
Integrated projects typically cost 10–15% less than sequential single-system projects because civil work, utility coordination, and electrical infrastructure are shared — and because a single contractor eliminates coordination overhead.
How do you size the three systems relative to each other?
We model the site load — including EV load — against solar production curves and battery dispatch to find the combination that minimizes total utility cost and maximizes renewable utilization. There is no one-size-fits-all ratio.
Who is responsible if one system underperforms?
When Voxline installs all three systems, we hold the performance warranty for the integrated system. There is no finger-pointing between solar, battery, and EV contractors — a single contract, single warranty, single point of contact.
