Commercial solar in Myrtle Beach, SC

Local commercial reality

The commercial picture in Myrtle Beach

Commercial solar on the Grand Strand is dominated by hospitality: hotels, resorts, restaurants and the retail that serves them. That produces a load profile unlike most commercial modelling assumes, because consumption is driven by occupancy and skews heavily to the summer months and into the evening rather than following a working day.

The seasonal skew is genuinely favourable, since peak occupancy coincides with peak production, and a resort property cooling hundreds of rooms through a July afternoon converts production at full retail value. The evening skew is less so, because restaurant and entertainment load continues well after production stops. Reading interval data rather than assuming a profile is what separates a sound projection from an optimistic one here.

Santee Cooper's retail rate of around 11.4 cents is the lowest we work with, which means each offset kilowatt-hour is worth less than in Duke or Dominion territory and payback is correspondingly longer at the same installed cost. Coastal specification and hurricane wind loading also add real cost. Horry Electric Cooperative serves many surrounding addresses on its own commercial terms, so confirm the meter first.

Written for Myrtle Beach specifically. Your own roof, bill and meter still decide the answer, which is what the free assessment settles.

Why now

The 2026 rate change hurt homeowners and helped businesses

When Santee Cooper closed one-for-one net metering to new systems at the end of 2025, it reduced the value of exporting surplus power. For a home that generates at midday and uses power at night, that was a real setback.

A commercial building has the opposite load shape. Offices, warehouses, retail floors and refrigeration draw hardest during exactly the hours a rooftop array produces hardest. Most of what you generate never touches the grid, so it offsets electricity at about 11.4¢ per kWh rather than earning about 4.16¢ per kWh in summer and 3.84¢ outside summer.

Put plainly: the rate change that made residential solar harder to justify in Myrtle Beach left commercial economics broadly intact, and in relative terms improved them. That is worth knowing if you looked at solar for your building a few years ago and set it aside.

Summer cooling load reinforces this. Your peak demand and peak solar production land in the same months and largely the same hours. Direct hurricane exposure and mandatory evacuation zones. Extended outages are a genuine planning case here, and for rental properties an outage during a booked week has a direct cost.

The same rate detail from the homeowner's side is on Myrtle Beach solar incentives.

Tax

Where we stop and your CPA starts

Commercial solar tax treatment is genuinely different from residential. Federal commercial provisions and depreciation may apply where the expired residential credit does not, and the structuring can materially change your return.

We are not going to model that for you. Installers who present themselves as tax advisers do their clients harm, and the numbers depend on your entity, your liability and your depreciation position, none of which we can see.

What we do instead: scope and build the system properly, document it to the standard your accountant needs, and route structuring questions to your CPA. If a competitor is quoting you a confident after-tax figure without having spoken to your accountant, treat that as a warning sign.
