Modern man per day consumes a huge amount of electricity obtained from non-renewable fossil resources. And this is precisely at a time when the sun above our heads daily emits billions of kilojoules of energy, the cost of which is zero.
That is why today so-called renewable sources of electricity, which are environmentally friendly and safe solar panels, are gaining increasing popularity. It is precisely such devices that are capable of converting the energy of the sun into the much-needed energy we need. electricity, which can be used by the consumer in his daily needs.
How do such devices work?
In the minds of most people, solar panels are a device capable of storing energy from the sun. But in reality, the process of converting sunlight into eclectic current is much more complicated ().
Let's try to take a closer look at what solar panels for a dacha consist of:
- Solar module– a structural element that is capable of converting solar energy into electric current;
- Breakers or circuit breakers— ensure safety when servicing such a battery and power supply system components;
- Device charge controller– this design element is responsible for switching between charging and standby modes, which allows you to significantly increase the battery life;
- Rechargeable batteries– act as energy storage devices generated by the modules;
- An inverter is an element that converts direct current from solar modules into alternating current, which is necessary for the trouble-free use of the building’s internal electrical network;
- Automation - this element may be needed if solar panels are a backup power source.
Note! It is the automation that allows you to switch devices connected to the power grid to the emergency network if a power outage occurs. And after the current supply resumes, switch the backup power grid to standby mode.
Having examined the composition of such products, you can be convinced that solar panels are not just a module for converting solar energy into electricity. Of course the converters are playing vital importance in such structures, but in addition to them there is a set of additional elements.
Types of solar panels
Depending on the type of solar module used, there are several types of products of this type:
- Monocrystalline silicon;
- Polycrystalline silicon;
- Thin film.
Note! The main difference between solar modules lies in the type of base material used in their manufacture.
Monocrystalline modules
The production of such elements is carried out from silicon crystals High Quality, so they are considered the most effective.
Note! Crystals for such devices are grown in industrial conditions. Instructions for increasing them were developed by the scientist Czochralski.
- The power of such a module is 30 W. The design of these elements is more compact due to their greater productivity, but such products are very capricious to the production conditions of their installation.
- In order to successfully use a system consisting of such devices, you will have to spend a lot of money, because the calculation of the average efficiency must take into account the reserve for the overnight downtime of the system, as well as for cloudy days.
- But if such a power supply system is not the main one, but a backup one, then the calculations will be somewhat different, and, accordingly, the costs.
Polycrystalline modules
Devices of this type are cheaper because lower quality materials are used for their manufacture. The productivity of such modules is 12-15%, while for monocrystalline modules the productivity reaches 20%.
Thin film modules
Such structural elements are made of amorphous silicon or other types of metals endowed with the necessary impurities. Compared to the options presented above, this one is the cheapest and least productive. The efficiency of such a system will be only 10-12%.
The advantages of thin-film structures include:
- Light weight;
- Simplicity and ease of installation due to the non-picky nature of the product;
- Flexibility.
The disadvantages include:
- Low productivity;
- Short service life.
Note! Due to their flexibility and low weight, such thin-sheet modules are more suitable for installation on the roof of a car or small boat.
If you are installing a solar battery for your dacha yourself, then you should definitely take into account the specifics of the location of the object. High efficiency you can only achieve if Sun rays will fall directly on the modules.
Advice. For achievement best efficiency The products should be installed at an angle of 40-45 degrees, so that they are oriented to the south.
Benefits of using solar energy
A set of solar panels for a summer residence is a system endowed with a number of positive qualities:
- By installing such products, summer residents gain the opportunity to use an autonomous power supply system that can cover all needs and will not require expensive maintenance;
- You will be able to receive environmentally friendly energy from an inexhaustible source;
- The system is absolutely silent;
- The system has high level safety for life and health;
- High-quality batteries will last you a very long time;
- To install such products on country and private houses you will not need any permits;
- Installation is quite simple and quite within the capabilities of the owners.
Disadvantages of using solar energy
The disadvantages of systems of this type include:
- A one-time investment that can seriously hit your wallet;
- In regions with a small number of sunny days, such a system will be ineffective;
- Over time, system performance will degrade by approximately 1.5-2% per 12 months.
Choosing batteries for your own dacha
How to choose devices in such a way that you invest your money wisely?
To do this, you first need to decide on the goal you are pursuing.
- If you are trying to create summer cottage additional or backup source electricity in cases of non-long-term shutdown of the central network, then solar panels are far from the best option investments.
- But if such outages happen quite often and last for several days, then such a decision will be completely justified.
Who needs solar energy
Solar panels are really necessary for the following groups of summer residents:
- People who decide to completely switch to autonomous system supplying electricity, which is an environmentally friendly product;
- People who constantly experience power supply system outages and in cases where such outages become prolonged;
- Anyone who has decided to reduce their own energy costs;
- If there is no electricity supply to the site at all.
When choosing batteries, you should take as a basis not the maximum or peak load, but the average. You should also take into account such an indicator as energy consumption per hour.
Knowing the values of these quantities, specialists calculate the optimal capacity of the batteries used, the required performance of the modules, and will offer you a set of solar batteries for your garden with the optimal parameters for you.
Note! An energy system based on solar panels in country houses or summer cottages does not yet require any permits or documentation approval. But if your dacha is located within the city, then you will need permission from the Russian Ministry of Energy to install such devices.
Finally
To summarize, we can conclude that optimal solution for those who decided to arrange on own dacha products based on monocrystalline solar modules (
The hybrid solar power plant SA-3000 is intended for use in a private home as an autonomous power supply system during the spring - autumn period or as an additional source of electricity in order to reduce electricity bills.
Main features of the Victron SA-3000 hybrid solar power plant:
- possibility of mixing solar energy to the network without using the battery resource, which will increase their service life to 10-15 years (the batteries will not be discharged and will always be charged 100% to ensure power supply to the house when the mains voltage is cut off, for example, during a network failure);
- the ability to limit energy consumption from the 220 Volt network at any level (you can set zero consumption from the network and as long as there is enough energy from the solar panels and/or from the electricity meter, the electricity meter will be stopped);
- switchable option to sell excess electricity to the general network (will be relevant in the future);
- the ability to temporarily increase the power of the network connection using solar energy and battery energy. When this function operates, the inverter is turned on and its output current is mixed with the grid current, thereby increasing the total output power (at the same time, the batteries are discharged if there is not enough solar energy);
- the ability to locally monitor the operation of the system from any smartphone, tablet, laptop via WiFi;
- the ability to operate the system from anywhere in the world via the Internet;
- possibility of connecting 2 groups of electrical consumers - one group with backup from the battery (lights, refrigerator, water pump, audio and video equipment, computer equipment, etc.) and one group without backup (powerful electrical appliances, for example, boiler, kettle, electric stove, etc. .P.). In this case, solar energy will be evenly distributed between two groups if there is a network, and if the network is turned off, all the energy will go to the first group;
- All SES components, except the battery, have a service life of more than 20-25 years.
The inverter power in the system is sufficient for long work any electrical appliances with a total power of up to 3 kW with a peak starting power of up to 6 kW. For example, for any refrigerator, lighting, TV, laptop, pump, heating boiler (except electric), any power tools, any chargers, vacuum cleaners, microwave ovens, etc. household appliances. If you need to increase the power, you can add another inverter or you can replace the inverter with a more powerful one (up to 15 kW).
Six solar panels with a total capacity of 1.5 kW will produce about 9 kW*hour of electricity per day in the weather in central Russia. Because in spring and summer in central Russia there are on average about 20 sunny days per month, then during the month the average daily energy supply from batteries will be about 5 kWh per day.
Annual electricity generation in central Russia will be about 1500 kWh, and in regions with high insolation, for example, in Crimea, up to 2000 kWh. At the same time, you need to understand that the distribution of electricity generation by month will be uneven and the maximum generation will be in the summer months.
The electricity received from the Sun can be used, for example, to power the following electrical appliances:
- Refrigerator class A++ with a consumption of 600 Wh/day - 600 Wh/h
- Well pump(800 W, 2 hours/day) - 1600 Wh
- Energy-saving lighting lamps (10 pcs. 20 W each for 3 hours/day) - 600 Wh
- LCD TV 40" (100 W, 3 hours a day) - 300 Wh
- Smartphone charger (10 W, 3 hours) - 30 Wh
- Laptop (50 W, 5 hours a day) - 250 Wh
- Vacuum cleaner (1500 W, runs for 30 minutes or 0.5 hours) - 750 Wh
- Microwave (1500 W, runs for 15 minutes or 0.25 hours) - 375 Wh
- Electric kettle(2000 W, runs 10 minutes or 0.17 hours) - 340 Wh
- Other electrical appliances with a consumption of 155 Wh/day
Total: 5 kWh per day.
The powerful charge controller used allows you to add another 500 W of solar panels to the system. In addition, you can install an additional controller and add it to the system required quantity panels, which will increase the average daily electricity generation.
- Rule for adding solar panels:
For every 1 kW of panels, you must add at least 2 batteries of 200 Ah each.
Used in this ready-made solution 4 gel batteries with a capacity of 200 Ah and a voltage of 12 Volts, capable of storing about 10 kWh electrical energy, which is enough for 2 days battery life in cloudy weather. If you need to increase the battery life up to 4 days, you can add 4 more batteries to the system.
The above calculation was made taking into account the operation of the power plant during the spring-summer period. Therefore, you need to understand that when operating the system in autumn-winter or when electricity consumption is more than 5 kW*hour per day, electricity will be periodically used from the network, or from an installed generator (if there is no possibility of connecting to the network).
For reference: 5 kW*hour per day or 5*30= 150 kWh per month- this is the typical electricity consumption in a house where 2-3 people live, subject to use gas stove. You can check the consumption in your home using your electricity meter or your monthly payment receipt.
When assembling a power plant in the technical department of our company, the inverter, controller and control panel, at the request of the customer, are programmed in one of many options for working, for example:
- Autonomous operation without network connection(the inverter input is configured to connect a generator; autostart of the generator “via a dry relay contact” is possible after the battery is discharged to a specified level, if the specified load power is exceeded, according to a schedule).
- Work with a permanent connection to a 220 Volt network. In this case, if there is energy from solar panels, the energy of the Sun will be used first, and if there is a lack of solar energy, electricity from the network will be used. In the event of a network outage, energy from batteries will be used at night, and energy from batteries and solar energy will be used during the day. The release of excess solar energy into the public grid is prohibited.
- Work with a permanent connection to a 220 Volt network and with a backup generator. Unlike the previous option, in addition to using the network, automatic use diesel generator in the absence of a network (automatic start of the generator is possible using various configurable parameters).
This system allows you to use the benefits of civilization in the form of electricity in places remote from city power grids. This kit is widely used among tourists for lighting tents and charging “gadgets.” ..

The solar battery kit for the dacha includes: two or three solar modules measuring 1-1.4 m, rated power 60-80 W and voltage 15.5 V, place them on the roof of your “house” and connect them to a car battery with a capacity of 90 A .h. Connect a small refrigerator, a light bulb and a portable TV to the battery through an inverter (DC-AC converter). And when the blue screen lights up in the evening, your neighbors will be attracted to the light in your window.
The “solar roof” on your “house” is essentially a completely autonomous mini-power plant. In recent years, such solar panels for dachas of varying power have become increasingly widespread in more than 70 countries where government programs have been adopted for the development of environmentally friendly solar energy that allows preserving irreplaceable natural resources of solar energy - from northern Scandinavia to the Australian deserts scorched by the merciless sun. In the conditions of the Far East and central Russia, solar panels for a dacha with an area of 15-20 square meters. m generate 1.5-2 thousand kW/h of electricity per year and have a guaranteed service life of at least 10 years. Two-thirds of this energy is received in the most important time for summer residents, and one-third in the winter. In many countries, individual solar panels for 3 kW dachas are built even where houses are connected to public power grids. The daily excess electricity is sent to the public grid. After sunset, the energy is returned to the owner of the solar power plant, and in the evening and at night, when power plants are underutilized, electricity is often received at a preferential night rate. Electronic meters vigilantly ensure that he pays only the difference between the electricity consumed and the electricity supplied to the network. Even a very small solar electric installation can find a variety of, sometimes very original, applications in personal plot. Example - solar-powered lamps for a dacha, installing one, even in dark time your lawn will be brightly lit. The batteries can charge batteries that will power decorative solar garden lights with LED or fluorescent bulbs in the evening, illuminating the landmark of your garden. Additional photocells will be able to turn on a lamp above a favorite flower bed or on a branching garden path only when the owners and their guests approach it. If you are afraid of a visit from uninvited guests, include an audible alarm in the electrical circuit of the solar installation. Despite their noble task, the development of clean energy, solar panels are not distinguished by a variety of shapes and external aesthetics. Brussels energy engineers plan to change the situation and produce solar panels of an unusual, spherical shape. They can collect and accumulate sunlight with significantly greater efficiency, which will reduce the battery area by 99% while maintaining the same power level. In addition, they can be installed in more places than flat counterparts.
