Photovoltaics how much you can save – a photovoltaic installation is recently, one could say, a construction craze. There is a widespread belief in the public opinion that whenever we build a new single-family house, we should invest in photovoltaic cells. Of course, this is not meaningless and it is worth taking a look at it, especially since very often people ask how much can be saved by investing in photovoltaics? Let’s take a closer look at this topic.
First of all, we need to invest
First of all, we must tell ourselves that, of course, we can save on photovoltaics and it is really quite good money, but we must first of all invest in it. This can be compared to a situation when, for example, we rent an apartment in a big city and after some time, we come to the conclusion that it would be cheaper and more beneficial for us to actually buy our own apartment, because the loan installment will be the same or even in some cases less than the monthly cost of renting an apartment.
It is similar with photovoltaic installations, we can of course save quite a lot of money on photovoltaics , but it is a process that is spread over time and before we start noticing the actual return on investment, and then savings, we must first of course invest in photovoltaics and wait.
Most often we take out a loan for solar panels. For most Polish households, the credit for photovoltaics will be in the range of PLN 20,000 to PLN 30,000. zloty. This is, of course, related to the different demand for electricity depending on the household and where we live, because in different regions of Poland, photovoltaics work more or less efficiently.
Of course, these are not very extreme values. In our latitudes, it pays to invest in photovoltaics, however, we can notice differences, even at the investment level, between, for example, the coast and central Poland.
How much can we save on photovoltaics?
We must immediately say here that all our considerations will concern a situation where the installation has been installed in accordance with the art, i.e. above all, the production of our electricity is optimal, i.e. it meets our needs, and at the same time there is no large overproduction, because a large overproduction of electricity by our photovoltaic cell is not profitable for us in any way, because we will not earn a penny on it.
In fact, what makes us save on photovoltaics is exactly how much we will not pay for the bills to the power plant. If we really want to understand what it’s all about. We should know how we will settle accounts with the power plant.
If we have installed solar panels, we sign a so-called prosumer contract with the power plant. So, on the one hand, we can take electricity from the national electricity grid, and on the other hand, we can give the electricity produced by our photovoltaic panels to the electricity grid. Well, a lot of people ask here a question, but how to give electricity to the general network.
Many people do not know that they will not be riding only on panels. The point here is more or less that photovoltaic panels are, after all, quite a capricious source of energy and not always when we would like to have electricity, it will be produced.
On the other hand, it often happens that when we do not need this electricity, it is produced in a very large amount. The best situation that describes this is the summer months, when the greatest production of electricity is when we are not at home. However, when we return home, electricity production decreases, i.e. in the afternoon and at night.
The settlement is based on the principle that we can take approximately 80% of the energy we have produced and returned to the grid from the national grid. So in fact, to be at “0”, we must have 20% overproduction in relation to what we consume. In an ideal situation, we simply won’t pay a penny for electricity. The only fees we will have for the power plant are the so-called operating fees, including for the maintenance of electric lines, but these are the same fees that all electricity consumers pay, regardless of whether they have photovoltaic installations or not.
A real return
In general, we can calculate it in such a way that if, for example, within one year, we pay about 3,000 for the power plant bills. PLN, and our installation cost us 25 thousand. PLN, the installation will pay for itself after less than 10 years of operation. The next 15 years, which are defined as the lifetime of the installation, is work for our profit.
So, in fact, we are able to save several thousand zlotys, and additionally put aside money for those panels that will have to be installed after 25 years. Of course, assuming that the price of electricity does not increase, and most likely it will increase over time, so the return on investment will probably be faster and we will start noticing the savings that result from having solar panels faster.
