FVE – yes or no

Topics: ENERGO

What are the main advantages of installing photovoltaic panels on your roof? And are there any downsides to consider before implementing?

Main advantages:


Let’s start with the good news. The cost of solar panels is much lower than it was 10 years ago. In recent years, there has been a slight increase in prices due to increased demand, but this does not change the fact that PV can save a significant part of your household budget.


The state provides subsidies for PV installation. There is no catch, any owner of a family home can apply. In addition, compared to last summer, the conditions have been significantly relaxed and simplified.


With a properly designed PV system, you will become energy self-sufficient to a greater or lesser extent. The electricity for your consumption will flow from an inexhaustible source of energy and you will thereby support the protection of the environment.

Panel recycling

Photovoltaic panels can be easily recycled. They are 90% glass and aluminum.

Long life and no maintenance

The guarantee for PV plants is usually provided for a period of 25 years, but the actual lifetime is longer. Maintenance costs are almost zero apart from regular servicing. FVE is a device that can appear to have a low failure rate, since the entire structure outside and inside the house is composed of fixed parts and components.

What are the potential downsides?

High cost of batteries

FVE with battery storage is more expensive, but this is compensated by the larger amount of subsidies provided. With a battery for solar panels located, for example, in the basement, you will get a big saving on energy and thus minimize energy losses. Despite the initial investment, the payback is around 10 years.

LOSKY will advise you in such a way that there is absolutely no situation where FVE would not pay off, if 2 essential requirements are met:

Shielding and use of the property

On roofs with an orientation exclusively to the north, roofs shaded by tall trees, FVE is not worth it. Furthermore, shielding with various elements on the roof, such as chimneys or roof pillars, can jeopardize the efficiency of PV plants. The energy obtained will go to waste even if you only rarely visit the object on which you want to install the solar power plant.
