Commercial solar could be huge – what’s holding it back?

70% of commercial buildings in the US could be a fit for solar, but only 3.5% have solar today, according to our new analysis with Station A.

As the Covid-19 pandemic wears on in the United States, commercial solar  projects built on businesses, schools and government buildings – will be hit hard. 

Compared to our pre-pandemic projections, we are forecasting a 32% drop in commercial solar installations in 2020. Commercial businesses  hugely impacted by current economic conditions  will likely opt out of discretionary investments such as installing solar this year. 

But what’s the true potential of this market in the post-2020 period? We teamed up with Station A, an AI-enabled clean energy marketplace, and collaborated on a first-of-its-kind analysis to find out. 

Quantifying the untapped potential 

Historically, measuring commercial solar potential has been challenging due to a lack of reliable data. By combining our project-level solar data with Station A’s building-level data*, we were able to get an accurate bottom-up view of this market for the very first time. 

The key findings won’t surprise anyone in the commercial solar industry: there is massive market potential. 

About 3.5% of all US commercial buildings have solar and another 1% are attached to community solar subscriptions, where customers buy power from a solar project located in the same utility territory. 

Not all buildings spend enough money on electricity to make solar a worthwhile investment. Once you account for those buildings — roughly 25% of the building stock — you’re left with approximately 70of the commercial buildings as potential targets for solar installers. That equates to more than 600,000 sites and 145 gigawatts of solar capacity potential. 

Why isn’t commercial solar growing more rapidly? 

Our market outlook has the commercial solar market growing at roughly 2 gigawatts a year from 2021-2025, bringing the installed total to around 8% of the total addressable market. 

But despite the enormous market potential, major challenges remain. Unlike residential solar that has standardized financing or utility-scale solar that has the benefit of scale, commercial solar has neither. 

Each commercial solar project has a high degree of customization and complexity. The work and expense involved in acquiring a customer and obtaining financing frequently kills deals. And the pandemic may temporarily exacerbate these problems by causing financiers to be more conservative. 

These are tough challenges that involve numerous financial and regulatory factors. Fortunately, there’s a slew of innovative companies working hard to solve these problems. If they can be overcome, a massive addressable market awaits. 

 

*Station A’s AI-enabled platform includes the majority of commercial buildings in the U.S. that have at least 10,000 square feet of roof space, roughly the equivalent of a 70-kilowatt solar project.
