Photovoltaics is a technology that allows the direct conversion of solar radiation into electricity. It uses photovoltaic cells, most often made of silicon.

A photovoltaic installation consists of solar panels, an inverter, cabling, and a mounting system. The panels generate direct current, which is converted by the inverter into alternating current used in home electrical systems.

With photovoltaics you can:

  • Significantly reduce your electricity bills
  • Become independent from rising electricity prices
  • Contribute to environmental protection
  • Increase the value of your property

Why Invest in Photovoltaics?

Benefits that convince more and more people

Financial Savings

Reduce your electricity bills by up to 70-90%. The return on investment usually occurs after 6-10 years.

Ecology

Production of clean energy without CO2 and other emissions. A typical 5kW installation reduces CO2 emissions by about 3 tons per year.

Grants and Reliefs

Possibility to benefit from funding programs and tax reliefs that significantly reduce investment costs.

Energy Independence

Independence from rising energy prices and potential power outages.

How Much Does a Photovoltaic Installation Cost?

Overview of costs and potential savings

The cost of a photovoltaic installation depends on many factors, including system power, component quality, and installation complexity. Average prices are as follows:

System Power
Estimated Cost After 30% Federal Tax Credit (USD)
Annual Energy Production
3 kWp
$5,600 - $7,000
~3,000 kWh
5 kWp
$7,700 - $10,500
~5,000 kWh
10 kWp
$14,000 - $21,000
~10,000 kWh

Remember, the above prices are indicative and may vary depending on the region and installer. Additionally, available funding programs—such as the 30% federal tax credit—can significantly reduce your investment costs. Be sure to check for local incentives and rebates that may further lower the total price of your photovoltaic installation.

Frequently Asked Questions

Answers to popular questions about photovoltaics

How long does it take to install a photovoltaic system?

The installation of a typical photovoltaic system for a single-family house usually takes 1-2 days. The entire process from signing the contract to commissioning the system can take from 2 to 8 weeks, depending on the waiting time for grid connection by the energy supplier.

Does a photovoltaic installation require maintenance?

Photovoltaic installations are practically maintenance-free. However, it is recommended to clean the panels periodically (1-2 times a year) and check the system's performance. Most manufacturers offer online monitoring, which allows you to track the installation's efficiency in real time.

What is the lifespan of photovoltaic panels?

High-quality photovoltaic panels have a lifespan of 25-30 years. Manufacturers usually guarantee that after 25 years, the panels will still achieve at least 80% of their initial efficiency. Inverters have a shorter lifespan, about 10-15 years.
