HYBRID SOLAR SYSTEMS

Hybrid photovoltaic power plants Hybrid PV power plants are combined backup power supply systems. In combination with modern electricity saving and storage systems it allows you to completely avoid interruptions in the supply of electricity, which are caused by scheduled or emergency shutdowns of the general electrical network. The need to install backup solar power plants is justified in those cases when the possible damage caused by the outage of the general power grid is greater than or equal to the cost of electricity that will be produced by the solar power plant. Hybrid power plants begin to function when there are interruptions in the supply of electricity from the centralized power supply system. The power of a correctly calculated hybrid solar power plant in combination with a battery pack is enough to completely replace the electricity deficit that can occur due to a power outage. In addition, the project of a hybrid solar power plant may provide for the possibility of using it to cover peak electricity needs. A hybrid solar power plant is a combination of characteristics of off-grid and grid solar power plant. In conditions of sufficient sunlight and with the correct selection of power, the solar power plant fully ensures the supply of electricity to the property, simultaneously charging the batteries. When the generation is reduced (onset of the evening, cloudy day), the shortage of electricity is covered by connecting the battery, and when it is discharged – from the general power grid. The main advantages of hybrid solar power plants: maximum flexibility and the possibility of implementing various work scenarios with the priority of both consumption and generation of electricity. minimization of electricity consumption from the general power grid and, as a result, a significant reduction in bills for consumed electricity. stable power supply of the object during fan, short-term and emergency power outages. compensation of the lack of electricity produced by solar batteries, due to the connection of other energy sources.

Depending on the total load power, which must be provided with electricity, the types and amount of solar modules, battery capacity, parameters of charge controllers and inverters are selected.

OFF-GRID SOLAR SYSTEMS

Off-grid photovoltaic power plants Off-grid PV power plants are the types of photovoltaic systems designed to stabilize the voltage supplied from an autonomous station. A stand-alone solar panel inverter acts as a stabilizer, with which you can equalize the voltage on the line and thereby prevent damage to equipment at your home or business. An autonomous solar inverter is a mandatory element for an autonomous energy supply system. Without it, the voltage supplied directly from the solar panels will not be able to ensure the stable operation of your equipment. Fully autonomous solar power plants are the least common specialized solutions that require the use of special equipment and have a higher specific cost. Off-grid PV power plant elements: Solar Panels Solar panels are the main component of a solar power plant. They consist of photocells that directly convert the sun’s energy into direct current. The panel has the following sequence of layers from top to bottom: On the inside, there is a block of input-output devices with electrical contacts for connection. Solar Mounting Structures Solar mounting structures are critical components that ensure the efficiency of a solar power system in both utility and rooftop applications.  Mounting structures for solar batteries can be ground, roof or hinged. For different locations, it is important to choose the right type and take into account various factors. For example, when mounting system placed on the roof or facade of a house, the weight of the structure is important. When installing on the ground, the geological features of the area, topography and climatic conditions are taken into account. Off-Grid Inverter Their functional purpose is to convert direct current (DC) coming from solar batteries into alternating current which are not connected to an external electrical network. The current is transformed through the battery chain. The energy generated in this way is used to power various household (or other) devices that are usually connected to the network. Solar Batteries The main purpose of a solar batteries is to store energy at the moment of its excess. As a rule, this process takes place during daylight hours, when the sun gives the maximum amount of light, the accumulated amount of energy is spent in the evening. In addition to accumulating and storing generated energy, batteries perform other important functions: For the correct operation of your system, it is necessary to calculate correctly the consumption of your house and choose the required capacity of the batteries. Solar Power Plant Monitoring and Control System It is intended for monitoring the parameters of operation, as well as the serviceability of all components of the SPP. Modern control systems allow remote continuous monitoring of all station parameters, equipment diagnostics, real-time display of all necessary information, and storage of all information about the state and operation of both the solar station itself and individual elements. Charge Controllers – MPPT Charge/discharge controllers are devices that not only control the process of charging batteries, but also allow optimizing the energy supply process for consumers when working from a battery unit, minimizing losses and extending the period of autonomous operation of the object. The main advantages of off-grid solar power plants: the possibility of using PV systems in places where the laying of a centralized power transmission line is either difficult or requires unreasonably high costs (for example, it can be objects of tourist infrastructure high in the mountains, on islands, or objects of construction at the initial stage, etc. .). silent operation and absence of mechanical wear of the equipment. the minimum level of maintenance and the absence of the need to involve expensive highly paid service personnel. CGP Solar Energy offers the installation of any type of off-grid solar power plants with the necessary technical characteristics, based on the tasks of a specific client. The specific implementation of the system is determined by the needs of the customer. Depending on the total load power, which must be provided with electricity, the types and amount of solar modules, battery capacity, parameters of charge controllers and inverters are selected.

GRID SOLAR SYSTEM

On-grid photovoltaic power plants On-grid PV power plants are one of the most common types of photovoltaic systems designed to generate electricity with subsequent transmission to the external network. Most often, electricity produced by a grid solar power plant (SPP) is sold to a third-party buyer at the market price. Grid solar power plants are divided into ground, roof, and building facades based on their design. Grid solar power plants can also be divided into large industrial ones (average power up to 1 MW and more powerful – from 1 MW) and less powerful private ones (usually their power does not exceed a few tens of kilowatts).   On-grid PV power plant elements: Solar Panels Solar panels are the main component of a solar power plant. They consist of photocells that directly convert the sun’s energy into direct current. The panel has the following sequence of layers from top to bottom: On the inside, there is a block of input-output devices with electrical contacts for connection.

When installing on the ground, the geological features of the area, topography and climatic conditions are taken into account. Network Inverters Their functional purpose is to convert direct current (DC) coming from solar batteries into alternating current with an industrial frequency. The main feature of the network inverter is simultaneously connected to both solar panels and the central power supply. This feature allows you to transfer excess energy received to the central system. In addition, it is possible to use energy from the central grid in case the energy supplied by the solar panels is not enough.Solar inverters can be used both for a small home solar system and for the construction of industrial solar power plants. They are perfect for backup and autonomous power supply systems. Solar Power Plant Monitoring and Control System It is intended for monitoring the parameters of operation, as well as the serviceability of all components of the SPP. Modern control systems allow remote continuous monitoring of all station parameters, equipment diagnostics, real-time display of all necessary information, and storage of all information about the state and operation of both the solar station itself and individual elements. Meters The meters provide accounting of the amount of electricity that is sold to the external general network. Cable lines Wired power lines or overhead power lines provide connection of SPP to the general (centralized) network. The main advantages of grid solar power plants: free, renewable energy, available in almost unlimited amounts – solar radiation. high reliability – modern solar batteries can be efficiently operated for 25 years. In addition, the plant has no moving/rotating parts that wear out quickly and require replacement. low operating costs – a modern solar power plant is distinguished by a high degree of automation of all processes, therefore it requires a minimum number of service personnel. service support of solar plants to maintain plant efficiency is very low – cost and does not require time-consuming and expensive operations. the possibility of using not only vacant areas for the construction of a solar power plant, but also those that are used inefficiently or not at all, for example, facades and roofs of buildings, not only allows you to save territory, but also significantly reduces capital investment in the construction of SPPs. the volumes of electricity generation are several times higher than those that were spent for its production. high rate of return on investment – currently, investments in solar energy pay off faster than in the oil and gas industry. the variability of the capacity of solar power plants makes it possible to produce the required amount of electricity and use it as efficiently as possible. high automation of all processes, which allows you to easily control all processes taking place at the station and optimize generation modes.
