Residential vs. commercial rooftop solar

Dutch solar energy is among the fastest growing renewable energy sources in Europe. In 2018, the Netherlands reached 4,400 megawatt of installed solar energy capacity, growing the installed capacity by 1,500 megawatt relative to the prior year (50% year-on-year).

Historically, residential rooftop solar was the main source. In 2018, almost 2,300 MW of installed capacity related to residential rooftop solar. However, commercial rooftop solar is gaining momentum. Out of the 1,500 MW increase in 2018, almost 530 MW was installed on commercial and utility roofs.

Government regulation and incentives, decreasing costs of energy and higher predictability of costs have contributed to the substantial growth over the recent years.

The Enterprise Agency (Rijksdienst voor Ondernemend Nederland (RVO)) announced support for a further increase in the installed capacity for the following years. The 2019 spring round of the SDE+ program illustrates this, where out of 5,376 SDE+ applications (2018: 4,411), 5,175 SDE+ applications (2,921 megawatt) were related to solar pv projects.

Commercial rooftop solar potential

The Dutch solar market has been growing over the years and has demonstrated a shift from residential small-scale projects to (mid) large-scale projects. In 2018, around 60% of the newly installed solar capacity was attributed to commercial ground-mounted and rooftop solar projects. In fact, based on the granted and submitted SDE+ applications, we expect that the share in solar power of the commercial and utility sector will continue to increase. The Netherlands is expected to reach an installed capacity of 6 GW in 2020 and 20 GW by 2035, of which a significant share will be realized through commercial solar projects.

Following Deloitte’s State of the State research on the potential for solar panels in 2018, we have analyzed the potential for solely commercial roofs in the Netherlands.

In order to estimate the Dutch commercial rooftop solar, our analysis focuses on appropriate roofs with a surface area of more than 6,000 m². However, we note that some identified appropriate roofs may already be subject to development or may even be operational at the time of the analysis. As such, to reflect the remaining potential, we have analyzed the current pipeline of granted and submitted SDE+ applications for some of the identified roofs and have captured these in the Rooftop Solar Tool as well.
