15kW Solar System in Afghanistan

Is a 15kW Solar System Right for You?

15kW systems suit large homes, guesthouses, small hotels, small commercial buildings and workshops with significant simultaneous electrical demand — often chosen by businesses that need most or all critical operations to keep running during grid outages.

How Many Panels Does a 15kW System Need?

A 15kW system typically needs around 24–28 panels, depending on the wattage chosen.

Battery & Inverter Options

A 15kW system is usually paired with a three-phase Deye or Growatt inverter, especially for buildings already wired three-phase. Battery capacity is typically built from multiple stacked lithium units, sized to the number of backup hours you need.

What Can a 15kW System Power?

• Multiple air conditioners
• Refrigeration equipment
• Water pumps
• Workshop tools or a small business's daytime operation

This size is built for higher continuous and simultaneous loads than typical residential systems.

Installation Considerations

A 15kW installation is a larger-scale project — expect a site visit, a wiring and load review, and typically two or more days for panel mounting, wiring and commissioning.

Warranty & Maintenance

Same 5-year LEMAR SunTech service warranty. At commercial scale, we recommend more frequent panel cleaning and periodic system checks given the higher usage.
