The advantages and disadvantages of a photovoltaic system

A photovoltaic system is a renewable energy source that converts sunlight into electrical energy. Currently, it is becoming more and more popular among private individuals and companies. But is the purchase of a photovoltaic system worth it? EnExpert lists some of the advantages and disadvantages of a photovoltaic system that should be considered when deciding on such a system.


1. Sustainable energy source: photovoltaic systems use the sun’s energy, making them a sustainable energy source that is independent of fossil fuels.

2. Cost-effectiveness: although the initial cost of a photovoltaic system can be high, it can be very cost-effective in the long run because energy production is free and operating costs are minimal.

3. Low maintenance: photovoltaic systems require little maintenance and have a long life span, making them a very reliable energy source.

4. Flexibility: photovoltaic systems can be installed in many different places, such as on the roofs of buildings, on open spaces or on mobile platforms. This allows for a high degree of flexibility in placement and use.

5. Independence from electricity suppliers: by installing a photovoltaic system, you become more independent of the electricity supply and can ensure your own energy supply. – Read also our blog article about virtual power plants to learn more about independent power networks.


1. Weather dependency: the power generated by a photovoltaic system is weather dependent and can be greatly reduced by bad weather, such as clouds. This can affect the efficiency of the system.

2. Initial cost: the initial cost of a photovoltaic system can be high, although the cost has decreased in recent years.

3. Space requirements: a photovoltaic system needs sufficient space to be used effectively, which is often a challenge in urban environments.

4. Power storage: storing excess energy can be a challenge, as it often comes at an additional cost.

5. Dependency on sunlight: Since power generation from a photovoltaic system depends on sunlight intensity, it is not always the best choice for locations with limited sunlight.


A photovoltaic system offers many advantages, such as sustainable energy production, cost efficiency, flexibility and independence from electricity suppliers. However, there are also disadvantages, such as weather dependence, initial cost, space requirements, and dependence on sunlight. It is important to consider individual circumstances to decide if a photovoltaic system is the best choice for your own energy supply.
