Solar power plants instead of roof covering are the same solar power plant, only they are not installed on, but instead of the roof covering. If you are replacing or thinking about a new roof for your home, consider an integrated solar power plant. It will be effective on the south, south-east or south-west slope of the roof.

With this decision, you save on the cost of purchasing and laying the coating and you have an exclusive glass roof. Suitable for all houses except flat roofs. Solar modules intended for installation instead of roofing are glass-glass solar modules SOLID Bifacial only with special holders SOLRIF. Parts are attached to each module, which allow the modules to be connected to each other on the roof like tiles. Grooves and special rubbers facilitate installation and help prevent leakage between modules. The installation starts from the lower part - by placing the solar modules slightly on top of each other.

Solar modules SOLID Solrif are specially designed to be integrated into the roof of a house, garage, greenhouse or terrace. The module performs both the primary function of electricity generation and the secondary function of roofing. Solar power plant with solar modules SOLID Solrif:

* It is suitable for covering the roof like any other roofing material

* Protects against water, snow, and other climatic conditions, just like a regular roof
* Ventilated
* Suitable for pitched roofs inclined from 12° to 7

Tin edges can be designed around the power plant to keep the roof completely covered with the new system and at the same time dry in all weathers. In addition, this system is also ventilated - just like any other roof covering

What should you pay attention to

An integrated solar power plant looks better if it occupies the entire roof plane, so the arrangement of the modules should form a rectangle. Solar modules in an integrated solar power plant are only installed horizontally

Integrated solar power plants are still relatively rare in Lithuania. The main reason is the price. Such a solar power plant is the most expensive. The second reason is that such a solar power plant is installed instead of a roof covering, so the moment when you can install such a solar power plant is either when you are building a house or changing the roof.

A very important aspect for a solar power plant is the objects that can block the solar power plant. Chimneys, trees or a multi-story roof can create a prerequisite for using optimizers.

If shadows fall on a part of the solar power plant or the entire plant, optimizers are needed for such a plant. If there are many modules receiving shade, such a solar power plant can become more expensive by up to 10 percent.

Solar modules are connected in a series circuit (or path). If one of the modules receives shade, it produces less electricity than the other modules. The shaded module(s) "pulls down" the whole grid after it - the power plant works on the power of the weakest working module. And this means reduced electricity production. To avoid this, we use optimizers TIGO. They help the solar power plant work efficiently regardless of whether the sun reaches all the modules equally.

Optimizers do not increase the performance of a solar plant if the entire plant is in the shade.

If the shadows do not fall on the power plant, there is no need for optimizers - the power plant will work at full capacity.

If you are still tempted by a "smart" solar power plant with optimizers on each module - you will be able to monitor how each solar module works and how much it produces at any time. It will be easier to notice if one of the modules is working worse. But before that, ask yourself the question - will you watch? Are you ready to pay an extra 1000 EUR for it? Did you know that if a module fails, even without optimizers you will notice it? Well, if the module fails, you still won't be able to change it yourself and you will have to call those who installed the power plant.

It is worth noting that optimizers use electricity. So, you will be able to use them less for your purposes.

All-black modules get hotter, and even with double-sided solar cells, they get less solar reflection to the back of the solar module, resulting in a small loss in power generation.

Choosing an all-black module is purely aesthetic, like choosing a car color. This is not just a whim of Lithuanian solar power plant owners - completely

black solar modules are taking over more and more private electricity producers from the solar market.

If we offer you a solar power plant, it will definitely be one of the offers with the completely black ones we produce solar modules glass-glass Blackstar and Standard full black

For owners of solar power plants - producing consumers, ESO installs a two-way metering electricity meter free of charge, which records:

* The amount of electricity consumed from the network;
* The amount of energy produced and supplied to the network.

The ESO meter does not calculate the total amount of electricity produced by the solar power plant, so if the readings of the inverter and the ESO meter differ, do not be alarmed - you use this difference in your home directly, without storage.

The data from the installed electricity meter is read automatically at a distance every month and based on the received data, the electricity consumption and its delivery (pickup from) to the network is calculated and transferred to the electricity supplier, who creates an invoice.

The readings recorded by the double-sided meter are presented in the monthly bill:

* how much electricity you produced and received from the grid
* how much electricity was missing (if any) and you took it from the grid
* how much electricity you have accumulated per month

Solar power plants are probably the objects that change the appearance and price of the house the most.

Several studies have been conducted in the USA - Berkeley Lab conducted a study in 2002-2013 and noticed that houses with solar power plants were sold more expensively than without them. The price difference is $4 per installed watt. So, theoretically, an average 5 kW solar power plant made the house more expensive by $20,000.

A somewhat more recent study was conducted in 2018-2019 at the National Renewable Energy Laboratory. We can evaluate its results in two ways: the study says that the price difference is already $5.9 per watt. Theoretically, a house with a 5 kW power plant costs $29,500 more than without it. Another statistical cut says that 1 saved dollar

increases the value of the house by 20. According to this statistical cut, a 5 kW power plant in Lithuania, even after considering the electricity conservation service, should immediately increase the price of the house by €10,400. So 4-5 thousand. the investment immediately increases the value of the house by more than double the amount.

During the research, it was found that houses with solar power plants are sold at least 20 percent. faster. Yes, this is the USA, yes, the prices of real estate and solar power plants are completely different there (at least twice as high), but no matter how we analyze the statistical data, everything says that the price of a house rises immediately. And, most likely, more than an investment in a solar power plant.

Producing consumers can transfer the accumulated amount of electricity to a new electricity supplier or a guaranteed supplier. In this case, the suppliers will have to coordinate with each other, but not the producing consumers themselves. Also, the generating consumer will be able to choose the alternative that when changing the electricity supplier, he must be compensated for the amount of electricity stored as stipulated in the previously concluded contracts, but no later than within 60 calendar days from the date of termination of the contract with the supplier. Up until now, it was foreseen that the producing consumers would be settled after the end of the accumulation period, so from now on they will be settled in a significantly shorter period of time. If the user does not choose any of these options, his accumulated amount of electricity will be automatically transferred to a new electricity supplier.

Have you installed a solar power plant and need to choose an independent electricity supplier?

If you have installed a solar power plant that meets your needs, from that moment on it almost doesn't matter which electricity supplier sends you bills. If the solar power plant produces a sufficient amount of electricity for you, then the electricity prices applied by the independent supplier will not cause inconvenience to you, and you will not need to buy additional electricity from the independent supplier. The independent supplier will monitor your cooperation with ESO and sell the excess energy you produce at market price during the times when the solar plant is operating and you are not using your own energy.

If you choose frameless solar modules, it is not necessary to clean them. Only when the sun comes out do they start cleaning themselves - the elements heat up, which helps the snow melt and slide away. Since there is no frame, there is nothing for the snow to cling to and therefore the snow slides off. If it

snows for several days or weeks, the solar power plants may not be able to clear themselves. In a typical Lithuanian winter, the generation of the solar power plant is very limited due to solar activity, so even daily snow removal will not bring much benefit.

There is no single answer. STANDARD and BLACKSTAR solar modules have somewhat rough or slightly frosted glass, which improves the efficiency of the module, but at the same time attracts dust a little more. The frame is another reason for them to last longer. Frameless glass-glass solar modules are completely smooth glass and are also covered with a special coating to prevent dust from sticking. If the module is empty, there is nothing for the dust to

catch. So, if you live in a slightly dusty area, cleaning (or at least checking for major dirt) a couple of times a year is enough.

If you live near a dusty gravel road, you should pay more attention than the average solar farm owner. More attention should also be paid after larger fires in the vicinity.

Solar modules are standardized products and therefore must pass a number of standardized tests. One such test is hail. During the hail test, an attempt is made to attack the solar module with standardized pieces of ice, and if there are no visible damages on the solar module after the test, it means that the module meets the standards and is given a declaration of conformity.

Hail trial has 6 levels. For solar modules, the first is usually enough. During it, the solar module is attacked with 25 mm diameter 23 m/s (82 km/h) 7.53 g pieces of ice 11 times to different parts of the module. A level 6 test would already be with a 75 mm diameter 203 g

39.5 m/s (142 km/h) chunk of ice. Well, such a piece of hail would probably break through the concrete.

Since hail with ice larger than 25 mm is extremely rare, solar module manufacturers, if they do such a test, usually limit themselves to the first level of the test. We also limited ourselves. And we can guarantee that if your solar power plant is hit by 25 mm diameter ice at a speed of 23 m/s, you can rest easy with both STANDARD and glass-to-glass solar modules. But if 6 hail test level 7.5cm diameter 200g icicles fall from the sky, you can forget about your solar power plant.
