Why solar panels are not a savings, but a trap for simpletons

“I’ll put solar panels on my house and I will NOT pay for electricity AT ALL”, - so many people think so. And what's wrong with that? And then you can still have a well - and abandon the water supply, and then... it's hard to say how far you can go in your desire for independence. But why do these bright dreams crash on harsh reality? Let's figure it out.

Why the desire for independence may be lost even before solar panels appear

To begin with, installing a solar panel system is expensive. Many enthusiasts literally fade away as soon as they see real calculations. For example, a small dacha system costs about 60 thousand rubles. Compare this with the cost of connecting to the mains electricity at 500-700 rubles and you will understand that only a very strong desire can overcome this barrier.

It turns out that only those who have no alternative in the form of power grids can decide to splurge on the installation of a solar system.

How much do you need for a private house?

One solar panel costs from 7000 rubles. The cost can be very different - it all depends on the size of the panel, its quality and, of course, on the manufacturer: the more promoted the brand, the more expensive.

But you understand that the panels will work only during the day, and on a sunny day, and in cloudy weather or at night, this system simply will not be able to function. And the energy will be consumed from the reserves accumulated during the sundial. And in order for a stock to form, there must be surpluses, and these are additional panels.

You need not one or two batteries, but at least four or more, depending on how much energy you need. And no matter how reliable these batteries are, they last 3-4 years, and then they will have to be replaced.

If you add everything together, you get not 60 thousand, but at least 300, and you still have to constantly invest in the planned replacement of panels and batteries. Are you ready for this?

Solar efficiency: is it enough to charge your phone?

In fact, solar panels have a rather low efficiency, and so far this is an insurmountable barrier, despite all the efforts of the developers. Solar panel with an area of ​​1 sq. The meter produces only 120 watts of energy on the sunniest day - just enough to charge your smartphone.

Now make a list of all the electrical appliances that you expect to use in your home and add up their power consumption. After the calculation, it remains only to imagine whether you have enough area to install the required number of panels.

Alternative or additional source?

So it turns out that there is no smell of economy here. How much will you "beat off" this installation? In general, it is not a fact that it will pay off ever, if only not at the moment when it has already become completely unusable. There is no question of free electricity here, as well as the fact that this system can act as an alternative to network electricity.

And yet there are still enough simpletons with burning eyes, as well as cunning marketers who "sell" expensive installations to them.

And here's another frankly about this type of energy from a practitioner:

What do you think about this type of energy? Do you believe that it can be an alternative to power grids? Maybe you have a better experience with these settings? Write about it in the comments!
