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 battery capacity, and installation costs. Here we provide an overview of the main expenses and influencing factors.

Cost of the solar panels

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

• Between € 250 and € 400 per panel (including installation).
  For 12 solar panels, you will end up with an amount of:

• € 3.000 to € 4.800.

The total cost depends on the capacity of the panels. With panels of 400 Wp, a set of 12 panels generates approximately 4,800 Wp, which is sufficient for an average household.

Cost of the home battery

The price of a home battery depends on the 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 the 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 complexity.

• Inverter: A hybrid inverter that supports both solar panels and a home battery costs around € 1.500 to € 2.500.

• Cabling and mounting materials: Costs 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, subsidies are available for solar panels and home batteries, allowing you to recoup part of the costs.

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