Installing Solar Panels: What Beginners Need to Know

The use of solar energy has long been successfully used by mankind: from primitive water heating to super modern solar power plants and autonomous chargers for gadgets.

Winter is coming, it’s time to try using an alternative source of energy and start saving money! And the snow? You ask.

Well, it is profitable and effective to install solar panels for your home in winter or early spring. Intrigued?

The fact is that clear, frosty days increase the efficiency of solar cells.

In addition, snow additionally reflects about 80% of sunlight. So, if solar panels are properly installed, during the snowy season, they give off the maximum current.

In this case, you can do it with minimal power. And with the increase in the duration of the daylight hours, this power may be enough for you.

Combined Approach

In case your home has a combined use of energy.

That is, in addition to the alternative, using the usual fuel, such as gas, then it is time to think about the quality of accounting consumed gas. You can, of course, use the services of companies, where the sale of gas meters with a magnet.

However, it is easier to install an additional solar panel module and not only save on electricity, but also use, and even store, the sun’s energy for free.

Solar panels for the home: typical mistakes of beginners

When installing alternative energy systems for the first time, many people turn to solar panel installation companies.

If you are new to this issue, please read the article to the end. And try to learn from others’ mistakes.

Mistake One: Greed

The most common mistake of beginners when installing an alternative energy source is the desire to get a system of a certain capacity. Well, for example: to have enough for the TV, and the refrigerator, and many other things.

In this case, you will pay at least 150 thousand rubles just for the solar system itself. Don’t forget to add the installation fee.

This installation will not last more than a year.

It turns out that you should not be greedy and in a hurry.

Since the system is modular, you can easily add solar panels and batteries as needed and as your needs grow, not as the seller wants. There is no need to pay for a solar system of maximum required capacity at one time.

It makes sense to buy the minimum required solar array in February or early spring.

Test and test the system in practice, to gain experience in rational use. And in autumn add the required number of modules, increasing the area of solar panels (it is desirable to provide this possibility in advance!).

Moreover, it will be possible to do the installation work yourself. Especially since you have already seen how to do it.

By the way, in the fall and winter periods, there may be substantial discounts. By the way, 12-volt solar panels can easily fit in the back seat of a car.

Mistake two: Wrong choice of operating voltage of the solar panel

When installing solar panels, it is necessary to correctly select the operating voltage and the corresponding batteries. For example, if you install solar panels at 24 or 48 volts, you will experience several inconveniences:

  • The need for careful selection of identical batteries (because you can not connect in series batteries of different manufacturers, different capacity and date of manufacture. That is, you will have to buy batteries in pairs!
  • Purchase of energy-saving LED lamps for 24 volts, and even more so for 48 volts is difficult
  • You will have to give up unified electrical devices for 12 volts (which are: alarms, pumps, phone chargers, radios, etc. devices).

Mistake three: relying on inverters

Another common mistake for beginners installing solar panels for the house: to power everything through an inverter, that is, one grid with a voltage of 220 volts.

But since the efficiency of inverters, in real life is only 75-80%, it is better to provide hybrid wiring: 12V and 220V. By the way, it can be run on one cable.

And now, everything that can run on 12V, let it be powered by 12V to your health (and that is: lighting, TV, satellite, and many other things). Such a solution will reduce energy losses by more than 30%.

Thus it will reduce the capacity of solar panels and the capacity of the battery.

And remember: only turn on the inverter to work with equipment that is not suitable for 12V. However, even a screwdriver can easily operate on 12V.

Mistake four: Choosing a battery

The first time you install solar panels for your home, you should beware of all kinds of deep-discharge battery models. They do not exist, except for alkaline batteries, which were installed on locomotives and electric cars.

Special mention should be made of gel batteries. Not only do they cost a lot, but given the following factors, they should not be used in principle, namely:

  • Due to the gel state of the electrolyte, such batteries do not enter the electrochemical process;
  • At negative ambient temperatures, the gel transforms into a state of paraffin. Judge for yourself, what will come out of this in frosty weather.

When installing solar panels for your home, use common inexpensive, time-tested battery models. Even used starter batteries removed from the car will do. Such devices will work reliably for another 5-7 years. Since there are more comfortable conditions than under the hood of the car: no overheating (100 degrees in the summer heat), huge starter currents and vibration. Thanks to the static nature of the batteries, no sludge rises from the bottom of the batteries, which disturbs the operation of the battery.


Mistake five: Incorrect installation of solar panels

Solar panels for the home will work effectively if properly and correctly installed.

There are several nuances, without observing which you can never save on the use of alternative energy:

  • Failure to comply with the azimuth
  • The wrong angle of inclination of modules
  • Absence of temperature control


So, having decided to install solar panels for your home and use the services of the appropriate companies, ask them for information about completed projects. Believe me, little to no professional organizations are sure to have them.

Don’t settle for the excuses, “Not convenient!” or “Not on hand…” Don’t be lazy, contact former customers and analyze what you’ve heard, or better yet, what you’ve seen. (A satisfied customer is usually easy to share a good result!).

Remember, before you part with a decent amount of money, it’s worth finding out as much as you can about the people you plan to pay it to.
