How Many Panels Do You Need to Power an Office and Warehouse Together?

Energy for two: powering operations without compromise

Running a business often means managing more than just one building. When your operations include both an office and a warehouse, your energy demand rises — and with it, your opportunities to save. But how many solar panels would it take to fully support both spaces simultaneously? The answer depends on a few key variables, but one thing is clear: sustainable energy is no longer just an option, it’s a competitive advantage.

Let’s break it down. A typical office with 25 employees may use 35–50 kWh per day, accounting for computers, lighting, HVAC, and server rooms. Meanwhile, a medium-sized warehouse — especially with lighting, automated gates, security systems, or refrigeration — can consume an additional 80–100 kWh daily. The combined demand could easily reach 130–150 kWh per day.

And that’s exactly where an inexpensive solar power plant in Poltava for logistics centers and warehouses can deliver long-term value.

Understanding the calculation

When calculating the number of panels required, you’ll need to consider several factors:

  • Average daily consumption in kWh
  • Effective sunlight hours in your region
  • Type and efficiency of the solar panels
  • Whether you need energy storage (for evenings or cloudy days)

In ideal conditions, a single high-efficiency panel can produce around 2–2.5 kWh per day. To meet a 150 kWh/day demand, you’ll likely need 60–75 panels. It’s best to build in a buffer to ensure full coverage year-round, especially during lower-yield winter months.

Many Ukrainian companies are already leveraging hybrid systems with battery storage and smart energy monitoring. In a recent project, a 1 MW solar power plant and turnkey price in Khmelnytskyi was implemented to power a complex combining office operations, refrigerated storage, and light manufacturing — completely eliminating dependency on the local grid.

Benefits beyond savings

Opting for solar isn’t just about reducing bills (though you will). It also helps stabilize business operations and elevates your brand’s reputation in sustainability-conscious markets.

Here’s what else it offers:

  1. Protection from future electricity price hikes
  2. Predictable operating costs
  3. Grid independence during outages
  4. Long-term return on investment
  5. Increased facility value and ESG benefits

Points to consider before installation

If you're considering a solar plant for your dual-purpose operation, here’s what to assess first:

  • Roof or land space available for mounting
  • Daily load variations between office and warehouse
  • Your business’s growth potential and future demand
  • Local regulations and possible grid integration
