Primary service area: New England & the East End of Long Island, with relationships beyond

Solar evaluated the way you'd evaluate any capital investment in your business.

I'm Bill Geyer, an independent Energy Advisor. I work with local business owners on the numbers that actually matter for the building they own: energy costs, demand charges, and available tax incentives. No generic pitch, just a straight look at whether the numbers work for your building.

If energy is a real, recurring cost on your P&L, it's usually worth a look.

How this works

Independent, and not tied to one installer.

I work in close partnership with a small number of established regional EPC firms suited to business-scale work, not whichever one is easiest, and not a generic residential crew scaled up. I'll walk you through cash purchase, loan, lease/PPA, or (where applicable) tax-equity structures, based on what actually fits your property and your business.

Commercial solar isn't just a bigger version of a residential system. The engineering is different, rooftop systems use specific racking and panel orientation plus required setbacks for code compliance, and so is the financing: it typically runs through commercial capital sources and depreciation schedules (like MACRS bonus depreciation) that a residential-focused lender or installer won't necessarily know how to structure. That's the gap I fill: someone who's actually done this at the business scale, not a generalist working outside their depth.

Outside that area? I have relationships beyond it. Get in touch anyway, I'll connect you with the right partner and stay your point of contact throughout.

Who this is for

Three questions decide whether this makes sense

Not a list of industries. Just the building and the bill.

  • Do you control the building? Owner-occupied is the most straightforward deal. Landlords with commercial tenants are often viable too, depending on the lease structure.
  • Does it have a good roof? Enough usable surface area, and not due for replacement in the next few years.
  • Is your electric bill high enough to justify doing something about it? If energy is a real, recurring cost, it's worth a look.

Not sure whether your situation qualifies? That's a five-minute conversation.

System types

What's typically installed

System Types

Rooftop: systems on large, flat warehouse or office roofs, using space that's otherwise unused.

Ground-mounted: for properties with open land, like farms or facilities with room to spare.

Battery Storage

On a business's electric bill, batteries are usually about demand charges, not blackouts. Many utility rate structures bill separately for your peak kW draw, and a battery that discharges during that peak can meaningfully cut that charge, independent of your total energy use.

If your operation has critical infrastructure needs, backup power during an outage is typically handled by a dedicated standby generator. The battery's role there is different: absorbing the load spike as equipment restarts, not carrying the building through the outage itself.

What it actually delivers

What it actually delivers

Cost Savings

Lower monthly utility bills, with predictable energy rates locked in for decades instead of exposure to rising or volatile rates.

Sustainability & ESG

Cuts your organization's carbon footprint, lowers Scope 2 emissions, and helps meet ESG (Environmental, Social, and Governance) goals, increasingly relevant to lenders, tenants, and stakeholders alike.

Tax Incentives

Under current law, the federal tax credit for business-scale solar (Section 48E) is still available, but only for systems placed in service by December 31, 2027. Businesses can also claim 100% first-year bonus depreciation (under MACRS) on a new solar system, which can meaningfully offset the upfront cost.

This is general information, not tax advice for your specific situation. Deadlines and depreciation rules can change, and how they apply depends on your business's tax position. Confirm current details with your accountant before deciding anything.

The Process

Solar evaluated like any capital project, and executed like one too

It starts with a plain conversation about your numbers, not a sales pitch. Here's exactly what happens along the way.

1
Discovery

A focused conversation about your building, your usage profile, and whether the economics justify going further.

2
Proposal

Using satellite mapping and your utility data, we build a system design before anyone sets foot on your roof or property. You receive a full proposal: system size, financing structure options (cash, loan, lease/PPA, or tax-equity where it applies), applicable incentives, projected savings, and an estimated payback period.

Nothing is signed and no capital is committed at this stage. The proposal is based on digital analysis. If the numbers work for your situation, the next step is a Letter of Intent and deposit, not a construction contract.

3
Letter of Intent and Deposit

Before engineering costs are incurred on either side, both parties sign a Letter of Intent. This formalizes the project's direction, establishes a defined window for due diligence, and in some cases involves a refundable feasibility deposit that offsets the costs of the engineering work that follows.

Nothing binding is executed at this stage in the sense of a final construction or financing agreement. The LOI is the formal commitment that moves the project from proposal to active development, and it protects both parties: the client is not locked into a contract before the engineering confirms the numbers, and the development team has the authorization needed to begin interconnection and structural review.

4
Site survey & engineering

An engineering team reviews the digital design against real-world conditions at your facility: structural load capacity, electrical service and switchgear, shading and orientation, utility interconnection requirements, and any site or title considerations specific to your property. If the engineering requires design changes, you see a revised proposal before the project moves forward.

Your contract includes a feasibility contingency covering the things that actually derail commercial projects: a utility interconnection issue, a permitting or zoning holdup, or a structural surprise like roof integrity, site conditions, or a title or lease complication. If one of those makes the project unworkable, you can walk away before major capital is spent.

5
Installation & turn-on

Your installation partner handles permits, utility interconnection, and the licensed crew. I remain your point of contact through commissioning and system turn-on.
