Increasing numbers of homeowners in the Hannover region are investing in photovoltaic (PV) systems with energy storage to become less dependent on rising electricity costs and actively contribute to environmental protection. But is such an investment truly beneficial? In this article, we provide a detailed overview of the advantages of a photovoltaic system with storage, key considerations, and the associated costs.

What exactly is a photovoltaic system with storage?

A photovoltaic system with storage consists of solar modules (panels), battery storage (batteries), and an inverter. Solar modules convert sunlight (sun) into electricity (direct current, DC). The batteries store excess energy for later use, typically measured in kilowatt-hours (kWh). The inverter converts the stored electrical power into alternating current (AC) that can be used by common household devices.

Your photovoltaic system, briefly summarized, includes:

• Solar Modules (panels): Designed to efficiently convert sunlight into electricity.
• Battery Storage (batteries): Store extra solar energy, providing a backup to manage demand when solar generation is low.
• Inverter: A Device that converts direct current into household-compatible alternating current.

Why does a photovoltaic system with storage make sense?

Maximizing Your Self-Consumption

Without storage, any additional solar power output during the day would commonly need to be fed back into the public grid at lower rates. By pairing solar panels with battery storage technology, you significantly enhance your self-consumption efficiency, allowing you to store and use electricity exactly when demand arises—even at night or during cloudy hours.

Independence from Rising Electricity Prices

Electrical prices in Hannover and Lower Saxony continue to rise steadily. Investing in a photovoltaic system combined with batteries effectively protects your house against these price hikes, offering long-term stability for your energy costs and helping you manage your electrical load efficiently.

Contributing to Climate Protection

Using renewable energy sources, such as solar or wind power installed in your home, actively contributes to environmental protection. This combination of technologies maximizes your self-generated electricity, significantly reducing your carbon footprint. Coupled with battery backup, it provides a reliable, efficient, and environmentally friendly solution.

How much does a photovoltaic system with storage cost in the Hannover region?

Costs for photovoltaic systems with storage vary depending on factors such as system size (measured in kilowatt peak, kWp), battery capacity, equipment quality, and the type of integrated components used. For orientation purposes, consider these approximate prices:

• Small Systems (approx. 5-10 kWp): around €15,000–€20,000
• Medium-sized Systems (approx. 10-20 kWp): around €20,000–€30,000
• Larger Systems (>20 kWp): individually calculated, typically starting from around €30,000

Funding and Subsidies for Your Photovoltaic System with Storage

In Lower Saxony, particularly in the Hannover region, homeowners can gain substantial financial support through attractive funding opportunities:

• KfW Funding: Nationwide grants and loans available for battery storage systems and photovoltaic installations. 
• Regional Programs: Cities and municipalities in Lower Saxony often provide additional financial assistance, ensuring more effective cost control.

We at PVPro Solar are happy to advise you individually about current funding opportunities and guide you through the entire application process.

For homeowners in Hannover, investing in a photovoltaic system with storage is undoubtedly worthwhile. It helps you increase your independence from energy providers and growing electricity costs by maximizing the use of produced solar energy. Storing excess solar energy enables you to use your own power even during critical times such as the evening. This increases your total energy efficiency and reduces your reaction to fluctuating electricity prices.

Unlike mechanical storage systems, such as pumped storage units, a photovoltaic system with storage combines solar panel arrays with battery storage equipment. This integrated system independently stores electricity, enabling you to choose precisely when to utilize your stored energy, ensuring optimal usage throughout any given time.

How long does a battery storage system last?

A high-quality battery storage system typically lasts between 10 and 15 years, sometimes even longer. Its lifespan largely depends on the number of charging cycles (how frequently the battery is charged and discharged).

Do I need a building permit?

Usually, you don’t need a building permit for smaller rooftop installations. For larger systems or special setups (such as ground-mounted installations), you should consult your local building authority.
