What size commercial solar system does my business need?

Commercial solar system sizing depends on your monthly kWh usage and three-phase load profile. Small factories typically need 20kW to 50kW. Larger industrial sites need 80kW to 125kW or more. SP-Energy provides free system sizing using your electricity bills and site information.

Do commercial solar systems work with three-phase Eskom supply?

Yes. All Deye three-phase inverters in our range connect directly to a three-phase Eskom supply. They are NRS 097 approved for South African grid-tie applications. Your installer uses these certifications for a valid COC and municipal approval.

How long does a commercial solar system take to pay back?

A well-sized commercial solar system in South Africa pays back in 3 to 5 years. Businesses with high daytime electricity consumption see the fastest returns. SP-Energy can calculate your expected savings and payback period before you commit.

Can I add battery storage to a commercial solar system?

Yes. Deye high-voltage battery stacks pair with the 3 phase inverter range for after-hours energy storage. This is especially useful for businesses that pay peak-rate Eskom charges. SP-Energy sizes the battery bank to match your after-hours load profile.
