Why targeting works

85% of commercial energy waste is concentrated in two line items.

It's not how much you use — it's when you use it. The same kWh costs $0.10 at midnight and $0.62 in the evening. Storage shifts the bill, solar cuts usage.

Buying electricity at Peak prices

"Peak" prices
~3× non-peak.

California TOU electricity prices by hour Bar chart of commercial electricity rates across 24 hours with three series: Non-Peak (orange), Peak (red), and SolarPorts (blue) — SolarPorts overlays the standard rate where available. Early hours (1am–6am): Non-Peak $0.12/kWh. Morning (7am–10am): Non-Peak $0.22/kWh. Midday (11am–3pm): Non-Peak $0.17/kWh vs SolarPorts $0.05/kWh. Peak (4pm–8pm): $0.57/kWh standard vs SolarPorts $0.05/kWh — over 10× cheaper. Evening (9pm–midnight): Non-Peak $0.12/kWh.

Battery can Time-Shift your consumption.

Surging usage creates large Demand charges

"Demand" Charges
~40% of most bills.

Monthly demand spikes vs. battery-smoothed average Line chart of electricity demand across 24 billing periods. Current demand (red line at the maximum spike): 83 units — what utilities bill demand charges on. Proposed demand (blue line at the average): 51 units — what the same site pays after batteries flatten the spikes. Roughly a 39% reduction. Proposed Demand Current Demand Billing Period Usage (kW)

Battery and Solar can Peak-Shave your surges.

Typical business owners waste $100,000 annual cash flow and lose $5M in property value paying high-cost Peak prices and Demand charges.

A strategic combination of battery and solar (rooftop and carport) can eliminate Peak charges and target Demand charges.

Using Power System Purchase financing owners retain far more benefits than traditional PPA or C-PACE financing.

In California, with some of the highest rates in the country, the results are compounded by avoiding the rapidly escalating energy prices.

Protect and insure against future price increases.

While the 'Big Three' utilities charge $0.50/kWh, SolarPorts locks in a Levelized Cost of $0.05/kWh. We don't just lower your bill; we give you a 90% discount on your building's most expensive fuel, avoiding future increases for 30 years.

The 20x Rule: In a 5% cap rate market, every $1 you shave off your operating expenses adds $20 to your building's value.

Beyond the savings, you gain a new revenue stream. Monetize your parking lot by selling low-cost energy to tenants via EV charging—turning a static amenity into a profit center.

How Financing Works

Power System Purchase financing means $0 CapEx and you keep all the benefits.

Our preferred financial structure is designed specifically for California commercial property owners who want to maximize their asset value without the restrictive terms of a traditional Power Purchase Agreement (PPA).

The Core Difference: Short-Term vs. Long-Term Debt

Most commercial solar providers push 20-25 year PPAs. While these require $0 down, they capture the majority of the financial incentives (Tax Credits, Depreciation, and Inflation) for the provider, not the owner. SolarPorts utilizes a short-term financing bridge that transitions into ownership, allowing you to retain significantly more equity.

Electricity Costs by Financing Type

SolarPorts pays $30k for the first four years, then $0 from 2030 onwards (30-year total $120k). PPA grows from $45k to $103k per year (30-year total $2M). Do Nothing escalates from $60k to $457k per year (30-year total $6M) under a 7% annual utility-rate increase.

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.

Savings and Costs for a sample 50,000sf building

Year 1 Savings Net Cost (with incentives) Pre-Incentives cost
$30,000 $60,000 $240,000

Battery only

Battery storage time-shifts away from high-cost Peak rates, flattens demand charges, qualifies for incentives, and ride through grid outages. Sized to your load profile, not a catalog.

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. 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. 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. 3

    Financing

    We work with you to secure 100% financing using local sustainable lenders to compete for your project. The California GoGreen program offers many solutions.

  4. 4

    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.

  5. 5

    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.

See exactly which California incentives apply to your site.

Federal ITC, MACRS, SGIP, SOMAH, CALeVIP — we model the full stack before you sign.
