Commercial solar, designed and built

Turn your roof into the cheapest power you buy

Heliograph designs, installs, and monitors commercial solar. Across the 41 systems we have commissioned since 2022, owners pay an average of 4.7 cents per kWh for power from their own roof, against a blended utility average of 14.1 cents in our service territory.

The math

The bill, before and after

A representative 480 kW rooftop from our portfolio, using twelve months of the owner's actual utility data. Your proposal is built from your interval data, not from averages.

Three questions to a site visit

Tell us the property type, roughly what you spend on power, and when you would want to break ground. Then pick a slot. A site assessor walks the roof, and you get a priced design within two weeks of the visit.

  • Incentive schedule with every program cited
  • Financed and cash pricing, side by side
  • Free assessment, no obligation to proceed
Process

Four steps, most of them ours

A commercial system typically runs 12 to 18 weeks from first site visit to energized, and the interconnection queue is the usual pacing item. We manage it end to end.

Week 1

Assess

Roof walk, structural review, shading study, and a pull of your utility interval data.

Weeks 2 to 5

Design

Stamped structural and electrical drawings, a production model, and the interconnection application filed.

Weeks 6 to 14

Install

Racking, modules, and inverters, usually four to eight weeks on the roof with your operations undisturbed.

Years 1 to 25

Monitor

Metered production checked against the model, with a report to you annually and alerts to us daily.

Incentives

The math is subsidized, and the subsidies are documented

Roughly half the cost of a commercial system in our territory is currently covered by federal and state programs. We model each one conservatively, and every line in your proposal cites the statute or program document it comes from.

Incentives change. Your proposal is dated, and we requote it if a program moves before you sign.

  • Federal investment tax credit30% of eligible system cost
  • Accelerated depreciation5-year MACRS schedule for most owners
  • State and utility programsVary by territory, itemized per project

Tax treatment depends on your situation. Confirm specifics with your tax advisor.

Refrigeration load runs day and night, so the array was sized to the daytime peak and the racking was engineered around 40-year-old roof penetrations.

About

Engineers first, salespeople a distant second

Heliograph was started in 2021 by two electrical engineers who kept getting asked to fix underperforming arrays other companies had sold. Most of the fixes traced back to optimistic production models. So we model conservatively, meter everything, and publish our fleet numbers.

The company holds electrical and general building licenses, carries the insurance your facilities team will ask about, and self-performs all roof work.
