Solar panels in the country. Turnkey solutions Factors that may affect the purchase of solar panels

With the onset of spring, mass migration of citizens out of the city, to their dachas, begins. It is good if the summer cottage is located close to the main power lines and is connected to them. And if not? Then you can solve the problem of electrification of a country house by installing a gasoline (gas) generator, a wind power plant or a solar power plant. Of these three options for solving the problem, the third option is the most optimal. It does not require large investments, and solar panels with a capacity of three kilowatts in the country are enough to provide comfortable living outside the city during the entire spring-summer period.

Solar power plant from Real Solar

The St. Petersburg company Real Solar has been operating in the solar photovoltaic market since 2010. During this time, a lot of experience has been accumulated in the design and installation of autonomous power supply systems in dacha cooperatives, country houses, cottages. Often, installing a helium home power plant is the best solution to the problem of providing electricity to remote buildings. If in order to bring a power line to a country house (it doesn’t matter if it’s an overhead line or lay a cable), sometimes you need to spend up to three hundred thousand rubles, then for the same amount you can buy a small solar power plant that will serve faithfully for decades. Plus, you don't have to pay for electricity.

For a small country house, it is quite enough to install a helium power plant with a capacity of three kilowatts. With a small load, such an installation may well provide a round-the-clock autonomous power supply. Its power is enough to support the operation of the refrigerator, with a chamber volume of up to 300 liters and energy saving class "A", lighting with energy-saving lamps. In addition, TVs of any models, radios, tape recorder, computer, various power tools whose starting power does not exceed 4.5 kilowatts, a garden pump or a submersible pool pump, as well as any chargers for various gadgets can be connected to the load.

Solar power plant kit from Real Solar

If the summer cottage is connected to the main power supply network, but the owner of the summer cottage, nevertheless, wants to install a helium power plant, then the company, at the request of the customer, can replace the autonomous inverter with a hybrid one. Then the consumer will receive the missing power from the main power grid, and if, on the contrary, he has a surplus of electricity, then this surplus will be given to the network. After the adoption of the law on the "green tariff", the payment for electricity will be made according to the difference between the consumed and delivered power, which will be recorded by a bidirectional meter.

This solar power plant is equipped with the so-called traction batteries of the American company Trojan battery. Such batteries are very well suited for small autonomous helium electrical installations. According to the manufacturer's specification, the number of recharge cycles is more than 850. The use of these batteries as part of the equipment of this solar power plant is due to their unpretentiousness, high endurance when operating in extreme cyclic modes.

In a typical set of power plants, eight batteries of the Trojan T-105RE 6V type are provided, which, when fully charged, accumulate eight kilowatt-hours of electricity. The duration of continuous operation without recharging (dark hours, prolonged absence of the sun) for a load of one kilowatt is eight hours. At the request of the customer, the number of batteries can be increased by eight, sixteen units. Accordingly, the battery life on the load also increases.

It is possible to connect a gasoline (gas) or wind generator to recharge the batteries in the absence of the sun for a long time (cloudy weather, dark time of the day for several days). In this case, a stand-alone MAC-inverter performs the functions of a charger.

Main technical characteristics:

Operating voltage - 48 volts, direct current
Output voltage - 220 volts, 50 hertz
Output contacts - 220 volts Two sockets, terminal block of the main switchboard
Operating output power - 2 kilowatts
Peak output power - (no more than 30 seconds) 3.8 kilowatts
Rated power of helium modules - 1000 watts

A typical set of a solar power plant includes four polycrystalline helium modules, one battery charge controller, a display for an MPPT controller, a MAP inverter, four batteries, two MC4 connectors in the kit, two MC4T connectors in the kit.

In addition to the main components, the package also includes six jumpers for batteries 250 mm long, one jumper 500 mm long, one jumper 750 mm long. All jumpers are made of wire with a cross section of 25 mm². The standard delivery also includes a rack for the battery and tools, a switchboard, a connecting cable for the battery charge controller, two meters long, with a cross section of 16 mm², kits for fixing helium panels and equipment installation.

Under a separate agreement, the company performs installation and programming of the station at the customer's site.

The cost of the kit is 270,000 rubles.

The SA-3000 hybrid solar power plant is designed 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.

The main features of the hybrid SES Victron SA-3000:

the possibility of mixing solar energy with the grid without using the battery life, which will increase their service life up to 10-15 years networks);
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 solar panels and / or from, the electricity meter will be stopped);
switchable possibility of selling surplus electricity to the general network (will be relevant in the future,);
the ability to temporarily increase the power of connection to the network using solar energy and energy in batteries. When this function is activated, the inverter is turned on and its output current is mixed with the grid current, thereby increasing the total output power (while 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;
the ability to connect 2 groups of electrical consumers - one group with battery backup (light, refrigerator, water pump, audio and video equipment, computer equipment, etc.) and one group without redundancy (powerful electrical appliances, for example, boiler, kettle, electric stove, etc.) .P.). In this case, solar energy will be evenly distributed between the two groups in the presence of a network, and when the network is turned off, all energy will go to the first group;
all SES components, except for batteries, have a service life of more than 20-25 years.

The power of the inverter in the system is sufficient for long-term operation of 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 and other 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 kWh of electricity per day in the weather in central Russia. Because in spring and summer in central Russia, 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 the Crimea, up to 2000 kWh. At the same time, it should be understood that the distribution of electricity generation by months 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 W * h / day - 600 W * h
Downhole pump (800 W, 2 hours/day) - 1600 Wh
Energy-saving lighting lamps (10 pieces of 20 W for 3 hours / day) - 600 W * h
LCD TV 40" (100 W, 3 hours a day) - 300 Wh
Smartphone charger (10W, 3hrs) - 30Wh
Laptop (50 W, 5 hours per day) - 250 Wh
Vacuum cleaner (1500 W, works 30 minutes or 0.5 hours) - 750 Wh
Microwave (1500 W, runs 15 minutes or 0.25 hours) - 375 Wh
Electric kettle (2000 W, works 10 minutes or 0.17 hours) - 340 W * h
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 the required number of panels to the system, which will increase the average daily power generation.

Rule for adding solar panels:
for every 1 kW of panels, at least 2 batteries of 200 Ah must be added.

Used as part of this ready-made solution, 4 gel batteries with a capacity of 200 Ah and a voltage of 12 Volts are capable of storing about 10 kWh of electrical energy, which is enough for 2 days of 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 is made taking into account the operation of the power plant during the spring-summer period. Therefore, you need to understand that during the operation of the system in autumn-winter or with an electricity consumption of more than 5 kWh per day, electricity will be periodically used from the network, or from an installed generator (in the absence of the possibility of connecting to the network).

For reference: 5 kWh per day or 5*30= 150 kWh per month- this is the typical electricity consumption in a house where 2-3 people live, provided that a gas stove is used. You can check the consumption in your home on the electricity meter or on the monthly payment receipt.

When assembling the power plant in the technical department of our company, the inverter, controller and control panel are programmed at the request of the customer on one of many job options, for example:

Offline work without network connection(inverter input is configured to connect the generator, automatic start of the generator "on a dry relay contact" is possible after the battery is discharged to a predetermined level, when the predetermined load power is exceeded, according to the schedule).
Work with permanent connection to a network of 220 Volts. In this case, if there is energy from solar panels, the energy of the Sun will be used first of all, and if there is a lack of solar energy, electricity from the grid will be used. In the event of a power outage, battery energy will be used at night, and battery and solar energy will be used during the day. The return of excess solar energy to the general network is prohibited.
Work with a permanent connection to the 220 Volt network and with a backup generator. Unlike the previous option, in addition to using the network, the diesel generator is automatically used in the absence of a network (autostart of the generator is possible according to various configurable parameters).

Model: SR-800

Solar power station SR-800 is designed for use in the country as a system backup power supply in case of a power outage lasting one or two days. If you need an autonomous power plant for a summer residence, then pay attention to other ready-made solutions - and.

The power of the PS800-24 inverter is enough to operate a class A two-compressor single-compressor refrigerator with a capacity of up to 300 liters, lighting, TV, radio, computer, drill, jigsaw, any chargers, etc. In a word, any electrical equipment with a maximum total power of up to 800 W with a peak starting power of up to 1.2 kW.

Two batteries with a capacity of 55 Ah and a voltage of 12 Volts are capable of storing about 1.3 kWh of electricity, which in cloudy weather is enough to operate the following electrical appliances for 24 hours:

Refrigerator with a consumption of 850 W * h / day - 850 W * h
Energy-saving lighting lamps (3 pieces of 20 W for 3 hours / day) - 180 W * h
TV 21 "(50 W, 3 hours a day) - 150 W * h
Mobile phone charger (5 W, 3 hours) - 15 Wh
Drill (600 W, works 10 minutes or 0.167 hours) - 100 Wh

Total: 1.295 kWh / day.

Two solar batteries with a total power of 200 W will produce about 1 kWh / day in clear weather in the Moscow Region. Thus, with a daily consumption of 1 kWh and clear weather, the battery energy will be enough to supply your dacha around the clock for an unlimited period of time. However, if the power consumption is greater than the total energy received from solar panels, or in case of cloudy weather, the actual battery life will be about two days.

The kit of a solar battery for giving includes: two or three solar modules with a size of 1-1.4 m, a rated power of 60-80 W and a voltage of 15.5 V, place them on the roof of your "cabin 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-to-AC converter). And when the blue screen lights up in the evening, the neighbors will be pulled into the light in your window.
