California's Commercial Solar Carport Specialist
High Energy Costs Hurt Your NOI
Strategic Cost Reduction for Significant Savings.
Most commercial energy waste is concentrated in a few specific areas. We use advanced analytics to identify those spikes and eliminate them, often with $0 in initial capital outlay.
It's a turnkey solution designed for the complexities of the California market - scaling seamlessly from single assets to state-wide portfolios.
- 75% Incentives
- 50% Savings Guaranteed
- 30-Year Warranty
- Industry Leader
Why timing beats quantity
Three numbers explain California's commercial energy bill.
It's not how much you use — it's when you use it. The same kWh costs $0.10 at midnight and $0.36 at dinner. Storage shifts the bill.
"Peak" prices
"Demand" Charges
~40% of most bills.
Battery and Solar greatly reduce your surges.
Electric Cost Inflation
~7% CAGR
Protect and insure against future price increases.
By the numbers
California has the highest commercial energy costs in the country. We've built our business on bringing them down.
California Energy Costs
$0.50/kWh
vs US average $0.16/kWh — 312% higher than the national average.
SolarPorts Energy Costs
$0.15/kWh
As low as $0.05/kWh with stacked federal & state tax incentives.
Typical Annual NOI Gain
$100k/yr
Per site. Direct, recurring impact on the bottom line.
Business Value Gain
$5.0M/site
Capitalized property value increase from a stabilized solar asset.
Your gains will improve as utility prices rise. We model the full 30-year cash flow before you sign — including federal ITC, MACRS depreciation, California SGIP, and demand-charge reduction.

What we do
Three integrated services. One project.
We start by examining your energy usage in 15-minute intervals and tailor a solution to maximize your return on investment. Laser focused on designing the smallest system possible to reduce your Peak and Demand charges, to avoid the highest costs — and their increases over 30 years.
Solar - Rooftop and Carport
Custom designs using our patent-pending pre-engineered solutions for rapid installation at the lowest prices.
- Single-contract EPC delivery
- Site-specific structural engineering
- Permitting across all California AHJs
- Premium-tier panels & string inverters
Energy Storage Solutions
Pair your carport with utility-scale battery storage to flatten demand charges, qualify for SGIP incentives, and ride through grid outages. Sized to your load profile, not a catalog.
- SGIP-eligible system design
- Demand-charge reduction modeling
- Backup power for critical loads
- UL 9540A-listed battery systems
EV Charging Integration
Bundle Level 2 and DC fast charging into the same project. Lower trenching cost, single interconnection, qualifies for utility EV-charger rebates and California's CALeVIP program.
- Level 2 (J1772) and DCFC up to 350 kW
- OCPP-compliant networked stations
- Load management to avoid demand spikes
- CALeVIP & utility rebate paperwork
Why SolarPorts
Built for California. Engineered for the CFO.
We're headquartered in San Francisco and exclusively focused on commercial carports, EV charging, and storage. That focus is the difference between a project that pencils and one that doesn't.
01
California-headquartered, statewide reach
Based in San Francisco. We've worked with AHJs across the Bay Area, Sacramento Valley, San Joaquin Valley, Central Coast and Los Angeles basin — we know the local permitting nuances before we break ground.
02
Single-contract EPC, not a brokered project
Engineering, procurement and construction sit under one roof. One schedule. One change-order process. One warranty. No finger-pointing between a steel vendor, an EPC and an electrician.
03
Designed for ROI, modeled before contract
Every proposal includes a 30-year cash-flow model: federal ITC, depreciation (MACRS), SGIP for storage, demand-charge reduction, escalating utility rates, O&M. You see the numbers your CFO needs before you sign.
04
Carport-grade structural engineering
Our structures are wind-, snow- and seismic-engineered to California Building Code. Cantilever, T-pole and dual-cantilever options span 30–60 ft to fit any parking layout without losing stalls.
05
EV-ready from day one
Trenching is the most disruptive cost in any retrofit. Building EV conduit and panel capacity during the original carport install means you can add chargers later for a fraction of the price.
06
Transparent on incentives, paperwork included
SGIP, CALeVIP, IRA / Inflation Reduction Act adders, prevailing-wage compliance, interconnection — we handle the paperwork. You get the credits.
How it works
Maximum cost reduction with minimum system.
By targeting your highest cost Peak and Demand charges, we can significantly reduce your costs with a small system. Sometimes, no solar is needed at all, just battery.
-
1
Free site assessment
Share your address and utility usage. We model production, ITC, MACRS and SGIP impact in 48 hours — no obligation, no sales pitch.
-
2
Engineered proposal
Site-specific structural and electrical design. Real cost, real timeline, real 30-year cash-flow model. Reviewed with your CFO and facility manager.
-
3
Permitting & build
We file with your AHJ, coordinate with the utility, mobilize, build, and commission. Average commercial project: 6–9 months from contract to PTO.
-
4
Operate & monitor
Optional O&M with 24/7 monitoring, performance guarantees, and incentive paperwork handled annually. You keep the savings, we keep the system humming.
Incentives stack
California solar is a stacked incentive market — if you know how to claim it.
Federal, state and utility programs can offset 50% or more of your installed cost when layered correctly. We model the stack for your specific site and handle the filings.
Federal Investment Tax Credit (ITC)
30% base credit on solar & storage under the Inflation Reduction Act, plus potential adders for domestic content, energy communities, and prevailing-wage compliance — stackable up to 50%+.
MACRS Accelerated Depreciation
Depreciate the system over 5 years (with bonus depreciation rules) to dramatically reduce your federal tax liability in the first project years.
California SGIP
The Self-Generation Incentive Program pays per kWh of installed battery storage. Equity, equity resiliency and small-business carve-outs significantly increase the rebate per kWh.
Domestic Content Bonus
Save an additional 10% by using domestic steel and US manufactured products.
CALeVIP & Utility EV Rebates
EV charger rebates from CALeVIP and utility programs (PG&E EV Charge Network, SCE Charge Ready, SDG&E Power Your Drive) cover a meaningful share of charger cost.
Net Energy Metering & NEM 3.0
Under NEM 3.0, paired solar+storage projects produce significantly better economics than solar-only. Storage sizing matters more than ever — we model it correctly.
