Solar for small business

What changes for a business owner compared with a homeowner, from tax credits to the lease on your building.

Updated September 3, 2026

The short answer

A small business can still claim a federal credit for solar, unlike a homeowner in 2026: the section 48E clean electricity investment credit has a 6% base rate, rising to as much as 30% for projects meeting prevailing wage and apprenticeship rules or exempt from them.

Business tariffs, demand charges and whether you own the building shape the economics.

Business solar essentials

A credit still exists

Section 48E, with conditions and deadlines.

Tariffs differ

Demand charges change what solar saves.

Own or lease the building?

A landlord must agree.

The commercial credit

IRS guidance sets the 48E base rate at 6% of qualified investment, up to 30% where prevailing wage and apprenticeship requirements are met, with 10-point bonuses for domestic content and energy communities.

Public Law 119-21 added termination dates tied to when construction begins and when the facility is placed in service. Our section 48E explainer covers the detail; confirm with your tax adviser.

Demand charges and tariffs

Many business tariffs bill peak demand separately from energy. Solar reduces energy charges reliably but may not cut a demand peak that falls at dusk. A battery can target the peak. Ask the installer to model your actual tariff, not a residential rate.

Model the tariff

Energy, demand, export rules.

Tax review

Credit eligibility and timing with your accountant.

Design and permit

Commercial permits may need engineering.

Install and interconnect

Then claim credits when placed in service.

What changes a small-business solar quote

Smaller than commercial, but priced on business terms.

Engineering	Structural and electrical stamps.

For pricing structure see the cost-per-watt guide.

Questions for a commercial installer

Have you modeled my tariff including demand charges?

Does the project meet prevailing wage and apprenticeship rules for the higher credit?

When will construction begin and when will it be placed in service, given the credit deadlines?

Is a battery worth it for my demand peaks?

Who is my contact for operations and maintenance?

Questions

Can a business still get a solar tax credit?

Yes, under section 48E, subject to its conditions and the termination rules in Public Law 119-21. Confirm eligibility with a tax adviser.

Can I put solar on a building I lease?

Only with the landlord’s agreement. A lease amendment should cover the roof, removal and ownership.

How is small business solar different from commercial?

Mostly scale. Larger projects face more complex interconnection and procurement; see commercial solar.

Primary-source research, data analysis and fact checking

We are a research desk, not a sales floor. We read the statute, the tariff, the code section, the federal filing or the manufacturer data sheet ourselves, and we publish the figure with the document it came from and the date we retrieved it.

Where a number cannot be traced to a primary source, we publish the shorter page and say what we could not verify. That rule has cost us whole sections, and it is why the rest can be checked.

160: primary sources read and cited
228: figures with a retrieval date
115: federal and state government sources
66: researched pages published

Authorship on this site is organizational: the analysis belongs to the desk rather than to a named individual, and we do not publish credentials we do not hold. Our editorial policy sets out how we source, date and correct what we publish.
