Poland’s storage market is growing rapidly – ​​now the software decides

The Polish market for home storage is experiencing explosive growth, even faster than the expansion of solar energy in recent years. More than 60,000 households already operate battery systems . However, behind this success lies a weakness: The majority of these systems are still "blind" devices that operate with primitive charge-discharge logic, without consideration for grid stability or cost-effectiveness in the home. Truly intelligent energy storage systems remain the exception.

Market dynamics: from niche to mass product

According to the Polish Energy Agency (ARE), by April 2025, more than 60,000 households and SMEs had already installed battery systems. Their total grid-connected capacity exceeded 314 MW and is approaching 400 MW, roughly equivalent to a medium-sized coal-fired power plant. These systems can supply or absorb around 3% of Poland's nighttime electricity demand —a signal that storage is now becoming a serious part of the energy mix.

Most systems rely on lithium iron phosphate (LFP) cells, averaging 5 kW of power and 12 kWh of capacity . This is enough to cover a household's daily needs . The actual number of installations is likely higher, as storage systems for pure self-consumption do not appear in official statistics.

By comparison , Germany's market is significantly larger, with over 2 million households operating a combined total of more than 10 GW of storage capacity . Analysts expect Poland to reach similar dimensions over the next decade, particularly due to the rise of plug-and-play storage.

The core weakness: in the “Dumb Terminal” trap

Despite the boom, most systems in Poland run with minimal intelligence. As software engineer Albert Wałczyk observes, mainstream brands like GoodWe, Solax, SMA, Huawei, or Growatt still lack advanced energy management strategies. Only a few new providers like Sigenergy integrate forecasts, dynamic tariffs , or user behavior .

Instead, the oldest rule still applies: Charge when solar power is available, discharge when it's not. This leads to three key problems:

• Grid load instead of relief : Storage facilities fill up too early in the day and leave no buffer for midday surpluses when the grid is at its most heavily loaded.
  
  

• Loss of household returns : In the Polish net billing system, revenue depends on timing. "Blind" systems sell electricity during periods of low or negative prices, thus destroying profitability.
  
  

• Useless assets in winter : Batteries often sit unused during the dark season, which doubles the payback period.

The result: households save less, the grid gains little stability, and subsidies are in danger of flowing into systems with limited benefits.

The solution: What “smart” storage really does

Truly intelligent storage needs more than capacity. The key is an EMS (Energy Management System) that makes data-driven decisions in real time. Key features include:

• Weather integration : charging/discharging planning based on solar forecasts
  
  

• Dynamic tariff optimization : Charge at low night-time electricity prices, sell at peak prices
  
  

• Consumption forecast : Adaptation to household load profiles for maximum self-consumption
  
  

• Grid support : zero feed-in and flexible load control against voltage peaks
  
  

• Modularity & Resilience : Scalable systems with emergency power capability in case of failures
  
  

This is precisely where Sunpura's EMS platform comes in. Unlike "blind" storage, it works with AI-based algorithms that connect to dynamic tariffs across Europe (Nord Pool, Tibber, Octopus, Omie), smart meters, and smart plugs. The system learns from consumption patterns, weather forecasts, and grid data, ensuring that batteries charge and discharge at the right time , not just at random.

The result: higher ROI for users and noticeable relief for the network.

Looking ahead: V2H and data integration

The next stage of development is Vehicle-to-Home (V2H) : electric cars as mobile storage systems with 70 to 100 kWh per vehicle. This significantly exceeds typical home storage systems and could become a key technology for energy security in Poland.

Deep data integration is equally crucial . Instead of simply estimating costs using complicated formulas, Sunpura's EMS architecture connects directly with energy providers' APIs. This allows decisions to be based on real end-customer costs—including all fees. This closes the loop between price signals and intelligent control.

A smarter path for Poland's storage market

The Polish home storage boom is a reality, but its long-term success depends on intelligence. Hardware alone creates neither economic viability nor grid stability. Only when storage systems evolve from simple batteries into smart energy brains will households, utilities, and society benefit equally.

At At Sunpura , we are convinced that this is the decisive step for Poland’s and Europe’s energy transition.

Our mission is clear: Plug in, Power Your Life – but smart.
