What is Commercial Solar?
Solar panel systems installed on business premises — offices, warehouses, farms — typically 10–200 kWp.
Quick Answer
The SEAI Non-Domestic Microgen Grant (NDMG) provides support for commercial solar installations. Businesses can also claim Accelerated Capital Allowances (ACA) — writing off 100% of the solar investment against tax in year one. Commercial electricity rates in Ireland (20–30c/kWh) make solar highly attractive for businesses with daytime consumption patterns.

Commercial Solar Explained
Commercial solar refers to solar PV installations on business, industrial, or agricultural properties. These systems are typically larger than residential (10–200 kWp) and are mounted on flat commercial roofs, warehouses, or car parks. Commercial solar offers businesses significant electricity cost savings, reduced carbon footprint, and potential revenue from excess generation. The economics are often more attractive than residential due to higher daytime electricity consumption and larger system sizes.
