Advantages of using solar panels in autonomous and backup power supply systems

Very often one comes across the opinion that using solar panels is inappropriate, that they are expensive and do not pay for themselves. Many people think that it is much easier to install a gas generator that will provide energy to your home. Let's try to figure it out and determine the advantages of using solar panels for home.

About the advantages of using solar panels

A photovoltaic solar battery has an almost unlimited service life (over 25-30 years, their production decreases by 10-20%). It does not make noise, does not require fuel, does not smell, there is no need to carry cans, change oil and build a separate (preferably fireproof) room with soundproofing walls, exhaust ventilation and an exhaust pipe.

If you have a solar power system, you can listen to the birds and watch the children play in the garden without breathing in CO2. But the main thing is electricity around the clock, and not only when the generator is running, started on the 10th attempt, and rattling to the “joy” of you and your neighbors. You always have a screwdriver, phone, camera, etc. charged. Is it logical to reduce the resource of a powerful generator in order to produce a few watts?

An undoubted advantage of round-the-clock power supply is the ability to install an alarm system. There are many options. From the simplest car alarm to an intelligent home with a DVR, GSM module, video on-line, and other bells and whistles. If you have a house, a temporary shed, or a sauna made of timber, then it is enough to install a car alarm with a seismic sensor (shock sensor). These are the simplest, cheapest and most sufficient options, because... wooden houses conduct low-frequency vibrations very well. It’s not for nothing that the best acoustic systems (speakers) are wooden. In the event of a break-in attempt, it will probably work, and even if it doesn’t arrest you, it will certainly have a psychological effect on the attacker (Who knows, maybe the whole “village” will come running now, or the neighbor with the “bazooka” will wake up?). The same can be said about a house made of logs; it is not much inferior to timber. For brick and stone houses, a car alarm with a volume sensor is more suitable; they are not much more expensive, 15-20%. And your property is “at least” protected. A canopy made of solar panels solves 2 problems - electricity generation and sun protection. 

One solar battery with a power of 80-100 W provides the necessary lighting, operation of a small TV, water pump, and trimmer. And anyone who went to school can handle the installation and connection. There are no “mechanics” in solar panels (in fact, there is nothing to break), tempered, textured glass is used, which does not reflect rays, allows you to collect 15% more scattered radiation, and withstands any hail and wind.

Moreover, the use of  solar panels  as a roofing material is very practical and aesthetically pleasing. In addition to generating electricity, partial shading and lighting of the attic or attic space occurs. Not to mention a self-sufficient gazebo, with lighting, a fountain and multimedia gadgets.

They often say: “In winter there is almost no sun.” I agree, almost not, but:

1. Firstly, in winter, electricity consumption can be reduced. This eliminates the issue with the refrigerator; it is the one that consumes the lion's share of electricity in the summer. You don't mow the grass twice a week with a 750-watt electric trimmer. There is no need to pump barrels of water every day for irrigation with a 550 W pump. Yes, lighting costs increase, but they are usually much less than what a refrigerator or powerful electrical equipment consumes.
2. The solar battery, from dawn to dusk, “silently” does its job even in cloudy weather. Although production in cloudy weather is naturally significantly lower than in sunny weather. But if you come in winter only for weekends and holidays, the question simply does not arise. Energy manages to accumulate in the batteries during your absence.
3. Thirdly, the lower the temperature, the higher the efficiency of the solar battery. Your task is to ensure that there is no snow on the solar panel. This is done by changing the installation angle of solar panels from “summer” to “winter”, which in our latitudes is 70-80º to the horizon.
4. If there is not enough energy, you will still have to start the generator in order to recharge the batteries.

Thus, with a properly designed autonomous power supply system, solar panels can improve the quality of life, living comfort and the cost of obtaining electricity not only in summer, but also in winter.

How to find a tutor?

When a child cannot cope with the curriculum, and exams are approaching, parents begin to sound the alarm about how to find a tutor. And it happens that adults themselves who want to learn something new need a tutor. Today, to find a good teacher, you don’t even have to get off the couch, but making a choice can be difficult. We'll figure out where to find a professional and what to pay attention to.

Why do you need a tutor?

The reasons may be different. Most often, parents turn to a tutor to improve their student’s performance and prepare for exams. Adults also need the services of specialists, for example, to learn a foreign language or master singing.

Even the most prepared students, who are confident that they know the subject by heart, would do well to contact a tutor - this will allow them to identify possible errors and correct them in time.

Before choosing a tutor, it is important to decide what exactly he is needed for - this way you will quickly find a specialist with suitable experience.

Where can I find a good tutor?

You have several options at your disposal. Let's look at the most popular of them:

Specialized Internet resources

You can find a good tutor on special websites, for example https://nice-tutor.com/.

The operating principle of such resources is similar and differs only in details. After you fill out your information, the service shows suitable candidates, and you call the one you like. When choosing an educational Internet platform, first of all, pay attention to the presence there:

• Questionnaires of tutors, which contain detailed information about each: their specialization, education, format of future classes.
• Real reviews from graduates and students.
• Information about the cost of classes, availability of subscriptions, discounts and other special payment terms.

Pros:  a very wide choice of specialists, and unsuitable candidates are eliminated automatically. It is also important that each applicant for employment undergoes a strict selection process.

Cons:  some top resources may inflate the cost of services. Therefore, it is better to compare prices on several sites.

Word of mouth

Asking other parents in the class, friends, or neighbors is an affordable and reliable way to find a teacher. However, you shouldn’t completely trust someone else’s opinion: your friend may like the tutor, but he won’t be suitable for your personal goals. Therefore, do not rush to conclude an agreement - first, take a trial lesson.

Plus:  the chances of getting caught by an amateur are significantly reduced, since you are getting a recommendation first-hand, and not from an anonymous person on the Internet.

Disadvantage:  the search circle is limited to your friends.

Social network

Many tutors actively use social networks and maintain their own pages. If you decide to look for a teacher there, pay attention to the following:

Plus:  social networks allow you to evaluate both the level of professionalism and how the tutor communicates.

Minus:  you do not rely on the teacher himself, but on the image he conveys and the comments of unknown people. So be critical about this.

• Professionalism of the teacher. The best indicator is student success. It’s good if the tutor posts the results of his work: client reviews, scores and diplomas.

• Communication style. This also cannot be ignored - it is important that you or your child find a common language with the teacher. See how the expert responds to comments and how he reacts to criticism. If something worries you, it is better not to contact such a specialist.

Personal qualities. The closer in spirit a person is to you, the easier it will be to interact. Pay attention to what topics the expert raises on his blog and what his interests are. This will help you make your choice.

Free advertisements

Tutors often post information about their services on free classifieds websites .

When choosing, be sure to pay attention to the reviews and ratings in the applicant’s profile. Some teachers offer to attend the first lesson for free or for a minimal fee - this allows you to get to know the teacher and decide whether it is worth continuing further cooperation or not. But if an expert demands payment for several lessons in advance from the very beginning, be careful: perhaps this is a scammer.

Plus:  unlike word of mouth, the choice of offers is much larger.

Minus:  it is possible that you will run into scammers or unqualified specialists, since free ad sites are available to everyone. In addition, you will have to call or write to each candidate yourself and check his competencies.

What to look for when choosing a tutor?

There are many specialists, but to choose the right one, consider the following factors:

• Realistic deadlines. You should be wary if the teacher promises to raise your scores in one week  - don’t expect a miracle. Let the teacher outline the work plan and the results he plans to achieve.
• Experience. What is important is not so much the experience of the teacher, but whether he has experience in solving your specific problem.
• Price. Please note that many truly talented teachers charge inexpensively, while others, on the contrary, inflate prices due to their extensive experience, although they themselves have not improved their qualifications for a long time.

First of all, start from your budget: in any price category there is a chance to find a professional.

What is important to discuss with your tutor before starting classes?

Even if you can't wait to start classes, it's a good idea to start by asking your teacher about the learning process. Points to discuss:

• Has the tutor had a similar experience? It’s great if the teacher has already faced the same problem as you, for example, preparing for an international exam in a foreign language. In this case, he knows about possible difficulties and imagines how to solve them.
• The results of the tutor's work. Ask the specialist about other students. Believe me, a good teacher is only happy to share his successes. 
• Selecting a program. Tutors study either using traditional textbooks or proprietary programs - both options can give excellent results. But if the teacher cannot clearly answer a question about the program, this is a bad sign.
• Hometasks. Homework is treated differently: some teachers place a lot of emphasis on independent work, while others prefer to do more in person. So, check in advance what strategy the tutor follows, what format you consider comfortable for yourself, and select the appropriate option.
• How the teacher will track progress. During training, it is important to monitor the student’s progress and adjust the program. You should not trust those who ignore this point.

How to save money on a tutor?

The terms of cooperation are set by the teacher himself based on his experience, level of education and other criteria, so bargaining is not always appropriate. However, if you are satisfied with the specialist’s qualifications, but the price for his lessons is high for you, try the following:

• Online classes instead of face-to-face classes. Ask if the teacher can conduct classes remotely - this way he (and you too) will not have to waste time and money on travel, which means he will be able to give a small discount.
• Group classes. In this case, the teacher will charge the amount for one lesson, and not for each student, so the total cost of classes will decrease. Yes, not all teachers recruit groups, but parents can look for like-minded people themselves and offer the tutor a new format.
• Let the teacher choose the time. Let's say a teacher only has free time early in the morning, but clients rarely agree to it. If such a schedule suits you, you can ask the tutor for a discount for studying when it is convenient for him personally, and not for you.
• Class subscription. Find out if you can buy classes in a package - this usually works out better.

How to find the right tutor: conclusions

• Before looking for a specialist, clearly formulate the problem that he will have to solve.
• You can look for a tutor through friends, on free classifieds websites, on social networks and on specialized Internet resources.
• Before concluding a contract, be sure to ask the teacher about how the classes will be held.
• If you are satisfied with the teacher, but the prices for services are too high, ask for a discount: offer an online format or group lessons.
• If you have been studying for a long time, but there are still no results, it’s time to think about changing your teacher.

Å spille i et Bitcoin-kasino, dets fordeler

I dag er det ingen person som ikke har hørt om kryptovaluta minst én gang. Dette er et moderne betalingsmiddel som lar deg foreta betalinger for varer og tjenester og utføre andre transaksjoner.

Gitt denne populariteten, er kryptopenger i dag, sammen med fiat-valuta, mye brukt i gamblingindustrien. Bitcoin og andre kryptomynter er en av betalingsmetodene på beste Bitcoin kasinoet.

Fordeler for spillere

Det er flere hovedfordeler.

konfidensialitet

Virtuelle spillinstitusjoner som bruker kryptopenger betyr absolutt anonymitet til spillet. I tradisjonelle landbaserte kasinoer med forskjellige  spilleautomater for etablissementer,  må hver besøkende, før du begynner å spille, oppgi sitt fulle navn og skanninger av identifikasjonsdokumenter. Svært ofte kan noen klubber kreve dokumenter om å ha en bankkonto.

Bitcoin kasinoer har ikke alle disse poengene, og for å begynne å spille trenger du bare å gå gjennom en enkel registreringsprosedyre.

Sikkerhet

Å spille Bitcoin nye casino på nett er helt trygt, fordi kundens penger bare tilhører ham. Det er ingen sperring av kundens konto dersom det oppstår problemer med bankkontoen, siden Bitcoin og andre kryptovalutaer ikke er avhengig av arbeidet til banker eller andre finansinstitusjoner.

Funksjonen til bitcoins, litecoins og ethereums skjer kun under kontroll av eierne deres.

Regelmessig økning i inntekt

Spillere, når de plasserer spill i fiat-valuta og mottar gevinster, avhenger av valutakursen. Penger vant for flere måneder siden og akkumulerte avskrivninger, siden de koster mye mindre etter en viss tidsperiode.

Med kryptovaluta er det ingen slike ubehagelige valutakurssvingninger, siden det udiskutable faktum er den høye volatiliteten til bitcoins og andre kryptomynter. I tillegg er veksthastigheten til Bitcoins verdi veldig imponerende.

Spill uansett størrelse

I et Bitcoin-kasino har hver eier av kryptomynter muligheten til å gjøre et mikrospill takket være muligheten til å dele Bitcoin i 100 millioner bytteenheter. Dette lar deg risikere kun små beløp.

Tatt i betraktning dette faktum, er Bitcoin-kasinoer tilgjengelige selv for brukere på et begrenset budsjett, eller for spillere som ønsker å spille et ekte spill uten å bruke store summer.

Ingen restriksjoner

I dag forbyr mange land ikke bare landbaserte gamblinginstitusjoner, men begrenser også tilgangen til online spilleautomater. I slike tilfeller vil det ikke være mulig å plassere et spill selv i en virtuell virksomhet, på grunn av det eksisterende forbudet på lovnivå mot å spille om penger.

Tatt i betraktning at kryptovaluta ikke er underordnet noen banker og ikke er regulert av statlige organisasjoner, oppstår det ingen vanskeligheter eller problemer med loven å leke med den. I tillegg avslører den ikke informasjon om eieren. Dette lar deg satse på nettkasinoer og motta gevinster.

Service av høy kvalitet, beste programvare

I moderne realiteter er Bitcoin-kasinoer en lovende bransje som ikke krever at eieren investerer en betydelig mengde kapital i starten. Når du spiller med Bitcoin, er det ingen store uttaks- og betalingsbehandlingskostnader slik det er med tradisjonelle spillinstitusjoner som håndterer disse transaksjonene gjennom banker.

Å fylle på din personlige konto og ta ut gevinster i kryptovaluta er helt gratis, uten noen provisjonsgebyrer. Takket være dette, når du spiller i et Bitcoin-kasino, er kundene garantert forsynt med attraktive bonuser, gunstige rabattsystemer og høye prosenter av avkastning til spillerne.

For å oppsummere, bør det bemerkes at spillene som er tilgjengelige i Bitcoin-kasinoer ikke er forskjellige fra  spilleautomater for kasinoer . Her har spillere tilgang til både spilleautomater og rulett, poker og andre spill.

How to choose a watch from a luxury brand

Every modern person cannot do without such an accessory as a wristwatch. It is not only beautiful, but also convenient. Luxury watches can emphasize the high status of their owner. After all, many people use their watch to determine whether a person has taste and wealth. Therefore, it is important not to make a mistake in choosing an elite accessory and pay attention to every little detail.

You can buy watches with crypto on the WATCHES WORLD website. The company guarantees high quality and originality of all products presented.

Frame

The price of a watch depends on various factors. One of them is the quality of the case and the type of material from which it is made. Accessories from the mid-price category are made with a steel body. This is a fairly high-quality material that is wear-resistant, does not scratch and retains its presentable appearance for a long time. For the manufacture of some models, a special coating is used, which allows you to imitate precious metals without raising the price of the watch.

The most expensive ones will be luxury watches for crypto, which are made of gold or platinum. Their cost exceeds the price of steel watches by ten or even more times.

Bracelet or strap

In classic watch models, a metal bracelet is most often used. Its advantages are that it fits perfectly with any style of clothing. This can be either a tracksuit or a business shirt with shoes. In addition, such a bracelet will be very durable. Its prestige directly depends on what metal it is made of.

More budget options include stainless steel, titanium, and brass. Accessories from the luxury segment are available with straps made of silver, gold or platinum. They can be inlaid with various precious stones, which significantly increase the cost of the product.

An alternative to a bracelet can be a rubber or leather strap. It can be both artificial and natural.

Manufacturer country

Many people know that Switzerland is the leader in the production of luxury watches. Accessories that were produced in this country are of the highest quality in the world. But they cost accordingly.

Another country that can compete with Switzerland is Japan. Watches produced by Japanese masters are also distinguished by their very precise mechanism, attractive design and durability.
