Is a PV system worthwhile? What you should know about photovoltaics

by Mike

The decision as to whether a PV system is worthwhile depends on factors such as your location and financial resources. PV systems are considered sustainable and environmentally conscious.

Making a decision as to whether a PV system is worthwhile

The use of renewable energies, such as solar energy through photovoltaics (PV), has increased considerably in recent years. More and more people are recognizing the benefits of this renewable energy source, whether for ecological reasons or to save money in the long term. But before you decide to install a PV system, you should know a few basic things about it.

  • Location: The location of your home is crucial. A PV system achieves the best results in regions with plenty of sunshine. Check the annual solar radiation in your region to get an idea of the energy yield of your system.
  • Investment costs: The purchase and installation of a PV system requires an initial investment. These costs can vary depending on the size and output of the system. You should carefully examine your financial situation and consider possible government subsidies or tax benefits.
  • Savings and return on investment: A PV system allows you to generate your own electricity, which significantly reduces your electricity bill. In addition, you can feed surplus electricity into the grid and receive a feed-in tariff. The return on your investment depends on the savings and income over time.
  • Maintenance and operation: PV systems require minimal maintenance, but you should consider the cost of occasional inspections and possible repairs.
  • Grid feed-in and self-consumption: Consider how much of the electricity generated you will use yourself and how much you want to feed into the public grid. The self-consumption rate can influence the profitability
  • Lifespan and warranties: Pay attention to the lifespan of the PV system and the warranties offered by the manufacturer. This often has an impact on long-term costs and reliability.
  • Maintaining value and property value: Remember that a PV system increases the value of your property. If you want to sell your home, this can be an advantage for you in the future.

The basics of photovoltaics: converting solar power into electrical energy

Photovoltaics is the conversion of sunlight into electrical energy.

  • This is done with the help of solar cells arranged in solar panels. These cells are made of silicon and absorb photons from sunlight, setting electrons in motion and generating electricity. This electricity can then be used to power your home.
  • A PV system is environmentally friendly and sustainable. It reduces dependence on fossil fuels and reduces greenhouse gas emissions, which helps to combat climate change.
  • In addition, solar cells are low-maintenance and have a lifespan of around 25-35 years.
