An Affordable Electricity Solution Without Solar Panels: Discover the 1Komma5° Promise in 2025

Julien Moreau

The energy market is undergoing a transformation, and with the constant rise in prices, the search for more affordable solutions is becoming essential. In this context, a German company named 1Komma5° is proposing an innovation that could truly change the game. The current energy revolution no longer relies solely on the installation of solar panels. With its PowerHarvester home battery, 1Komma5° offers a powerful alternative for households looking to save on their electricity bills while integrating the dynamism of energy markets.

The promise of 1Komma5°: accessible energy for all

Based in Hamburg, 1Komma5° positions itself as a pioneering company in the field of clean energy technologies for individuals. The launch of PowerHarvester marks a significant step in how households can manage their energy consumption. One of the main appeals of this device lies in its ability to store electricity at low prices and then release it when prices soar. Who hasn’t dreamt of not worrying about bills at the end of the month? 💳 Instead of relying solely on solar panels, PowerHarvester offers an accessible solution for every home.

An innovative technology

The PowerHarvester is much more than just a battery: it is a true energy management system. Available in several configurations, ranging from 7.7 kWh to 27.2 kWh, it is aimed primarily at households that want to optimize their consumption without having to resort to solar panels. Thanks to its infrastructure compatible with various types of inverters and charging devices, this technology eliminates the need to purchase specific equipment, making integration even simpler. This compatibility is a major asset for expanding adoption of the solution, especially in a context where consumers are often lost in the multitude of available options on the market.

  • 💡 Compatibility with all inverters
  • ⚡ Standalone solution even without solar panels
  • 📊 Intelligent energy management

With lithium iron phosphate technology, the PowerHarvester also ensures enhanced longevity and safety, without any superfluous features. This choice of battery, although more expensive, guarantees optimal use and a prolonged lifecycle, a crucial factor in the life of a product intended to transform how individuals consume energy.

Configuration Capacity (kWh) Price (€)
Configuration 1 7.7 8,900
Configuration 2 27.2 8,900

Saving on electricity bills

One of the major advantages of the system lies in its mechanism for purchasing electricity at reduced prices. By subscribing to a dynamic tariff via the Energy Trader tool, the device automatically purchases electricity when prices drop, allowing users to make significant savings. According to data collected by 1Komma5°, users could save up to 50% on their electricity bills. For households consuming more than 10,000 kWh per year, a threshold often reached by those equipped with energy-intensive devices like heat pumps or electric cars, this investment pays off in about six years. A new era of energy is emerging, at the intersection of accessibility and intelligence.

The operation of the PowerHarvester system

At the heart of this innovation is the effective management of energy purchases based on market fluctuations. When a customer subscribes to the Dynamic Pulse service, they are offered a monthly subscription of €9.90 for the Energy Trader service, which ensures the optimization of electricity purchases. This strategy is crucial in a market where rates can vary significantly from one minute to the next.

Real-time price monitoring

The system operates using a connected meter that continuously tracks price variations. Users receive real-time information, allowing them to interact effectively with their consumption. The idea is simple: buy when the rate is lowest and store for later use. This becomes even more interesting when prices rise, as the accumulated electricity can not only be used by the household but also sold for profit. This proactive approach offers unparalleled freedom of action, especially in the current economic context where every cent counts.

  • 💸 Purchase of electricity at low prices
  • ⚙️ Optimized management through AI
  • 📈 Individualization of energy needs

It is undeniable that this method is disrupting traditional energy practices. No longer is it a question of enduring price hikes without action. Thanks to PowerHarvester and its associated tools, controlling one’s consumption becomes not only a budgetary necessity but also a conscious choice regarding energy use. With such management, the promise of savings on the electricity bill is no longer a pipe dream, but a tangible reality.

Potential Savings (%) Household consuming less than 10,000 kWh Household consuming more than 10,000 kWh
30% Not significant Repayment > 6 years
50% Not significant Repayment < 6 years

A future energy strategy

The question of households’ energy autonomy is more crucial than ever. While large energy suppliers like TotalEnergies, Engie, and EDF continue to dominate the market, the emergence of solutions like those provided by 1Komma5° is gradually reshaping the energy landscape by offering more flexible alternatives.

A challenge for the industry

The launch of innovative products in the energy sector also poses challenges to an industry often perceived as rigid. The product manager at 1Komma5°, Jannik Schall, emphasizes that “the real challenge of the energy transition lies in the rigidity of current networks, which does not allow for the emergence of flexible solutions like PowerHarvester”. Indeed, the necessity to rely on modern infrastructure and the integration of smart meters are essential prerequisites.

  • 🔌 Flexibility of the energy infrastructure
  • 🏗️ Necessary modernization of networks
  • 🔍 Evolution of consumption behaviors

The fact that 1Komma5° adopts a pragmatic approach to these challenges may well redefine the role of households in this transition. The integrated energy storage and management system opens a pathway towards greater autonomy, without being constrained to installing solar panels which, ultimately, may not suit all households.

Current Challenges Proposed Solutions
Rigidity of networks Development of flexible systems
High installation costs Accessible solutions without panels

Reactions and perspectives for 1Komma5°

Even though 1Komma5° is making great strides, the startup faces additional challenges. The ambition to produce its own solar panels has been paused, deemed too risky given the costs of energy and labor. Additionally, the plans for a 1 GW factory scheduled for 2024 are currently on hold, casting a shadow of uncertainty over future investments.

Toward a necessary evolution

This situation highlights the need for quick adaptation in a constantly evolving market. Heavy import taxes and fluctuations in energy prices weigh on the brand’s expansion strategy. This caution is understandable, but it could also provide an opportunity to orchestrate a more thoughtful transition rather than a rushed one. The emergence of a system like PowerHarvester also underscores the importance of having alternatives that are both readily available and practical for households, without solely relying on renewable energies; why not engage heavyweights like Iberdrola, Planète OUI, or GreenYellow to support the rise of such solutions.
