The cost of a system with 12 solar panels and a home battery depends on various factors, such as the quality and capacity of the solar panels, the capacity of the battery, and the installation costs. Here we provide an overview of the main cost components and influencing factors.

Cost of the solar panels

The price of solar panels varies by brand, type, and power. On average, a solar panel costs:

• Between € 250 and € 400 per panel (including installation).
  For 12 solar panels, the total amounts to:

• € 3,000 to € 4,800.

The total costs depend on the power of the panels. With panels of 400 Wp, a set of 12 panels generates about 4,800 Wp, which is sufficient for an average household.

Cost of the home battery

The price of a home battery depends on its capacity (expressed in kWh). Some examples:

• 5 kWh battery: € 4,000 to € 6,000

• 10 kWh battery: € 7,000 to € 10,000

• 20 kWh battery: € 12,000 to € 15,000

For an average household, a battery of 5 to 10 kWh is often recommended, depending on energy consumption and desired level of self-sufficiency.

Installation costs

The installation costs for solar panels and a home battery include:

• Labor costs: Vary between € 1,000 and € 2,500, depending on the complexity.

• Inverter: A hybrid inverter that supports both solar panels and a home battery costs about € 1,500 to € 2,500.

• Cabling and mounting materials: Costs for this range between € 500 and € 1,000.

Total costs

For a complete system with 12 solar panels and a home battery, you can expect the following price ranges:

Savings and subsidies

• Subsidies and tax benefits: In many regions, there are subsidies available for solar panels and home batteries, allowing you to recover part of the costs.

• Energy savings: With such a system, you can save hundreds of euros per year on your energy bill.
