How not to be mistaken in choosing solar panels

In this article I would like to talk about how and what people make mistakes even before buying solar panels. Let's take a look at the most common cases.

1. You've probably seen the “expectation versus reality” demotivators more than once? This can be your first mistake. You saw a ready-made set of a solar station for summer cottages with a power of 500W. and think that this will allow you to disconnect from the general network and thereby provide yourself with autonomous energy. Unfortunately, this is not at all the case. What can you advise? The easiest and cheapest way is to call a specialized company that installs solar stations and they will make a preliminary calculation for you absolutely free.

2. The next mistake is - I want a solar station like my neighbor has. In this case, you can get a project that is not economically profitable for you. It follows that you must understand exactly why you need a solar station and only after that carry out the calculation.

3. The next moment, at which an error of incorrect calculation of solar panels can creep in, is an incorrect determination of the energy consumption of your electrical appliances. In this case, carefully study their technical documentation or use special devices. Here it is also desirable to take into account the possibility of increasing consumers over time. (in more detail in this article)

4. And now a small example of how the possibility of reducing electricity consumption affects the cost of a power plant, and if this is not taken into account, then you can seriously overpay.

The cost of 1 Watt of a solar battery is about 10gr.

We will replace the 60W incandescent lamp. for LED 10W .. It will cost us 30 hryvnia. The savings goes out to 50 watts. And the cost of a 50W solar battery is 500g. Draw your own conclusions!

5. The following errors can be attributed to editing (we talked about the subtleties here). If you install solar panels yourself or entrust this task to inexperienced installers, the following may happen: an incorrectly chosen direction of installation of the panels will very sharply reduce the generation of electricity, or for example, if ventilation is not taken into account and the panels will overheat, this also greatly affects the generation of electricity and there are many such features.

6. And we come to one more subtle point, this is a mistake in choosing a seller of solar panels. If you are offered unique technologies at a price significantly lower than the market average, you should be on your guard. If you hear a panel efficiency value of more than 25%, this should also alert you.

What conclusion can be drawn from all these examples? To minimize risks, even at the start of construction and procurement of equipment, it is at least necessary to consult with specialists with extensive experience and a large number of completed projects. And in order not to be 100% mistaken and to do everything as competently, economically and quickly as possible, it is better to entrust all the turnkey work to specialists.
