A hybrid solar power station is gaining popularity as an alternative energy source, combining features of autonomous and grid-tied systems. This innovative power system is often installed in residential buildings to ensure stable and economically efficient consumption.
Hybrid solar power stations: a multifunctional system for uninterrupted power supply
Hybrid power stations are combined systems that integrate both autonomous and grid-tied functions. Their installation offers several obvious advantages:
- Energy is not only generated but also stored in selected batteries for backup use.
- Continuous access to the grid ensures power consumption without dependence on the time of day or weather conditions, unaffected by power outages and emergencies.
- Environmentally friendly energy usage.
- More than a 50% reduction in utility bills.
A hybrid solar PV station becomes an efficient source of electricity when the connection to the stationary grid is temporarily unavailable. In such situations, the solar power system is designed to operate at full capacity, meeting the homeowners' needs. Once the main power supply is restored, the system can be switched to the appropriate mode based on specific conditions..
Viability of hybrid solar PV stations: who benefits from acquiring a multitasking system?
While the cost of a hybrid solar power station is higher than that of autonomous or grid-tied counterparts, for certain individuals and businesses, this investment is fully justified:
- Manufacturing owners operating 24/7..
The primary reason for acquiring a hybrid power station is to secure independence from unforeseeable events, such as voltage surges and power interruptions, which can have adverse effects on the functionality of valuable equipment. - Private homeowners..
The installation of a hybrid power station guarantees voltage stability in the home network, allowing residents to store energy for evening use, cloudy weather, or increased power requirements of household appliances.
Both businesses and individuals can expect significant cost savings by paying only for the electricity received from the grid. The most substantial additional bonus for private individuals is the possibility of participating in the Feed-in tariff program to earn income from selling unused kilowatt-hours. Excess energy generated by solar panels is transferred to the grid, generating revenue from the government.
The complete payback of the project is observed within 5-8 years of operation.
When storing converted solar energy becomes relevant
One of the key reasons to invest in a hybrid solar station for a residence is the assurance of achieving the highest economic efficiency from the renewable energy system. In cases where the house is unoccupied during daylight hours, and electricity usage is minimal to support the operation of heating and other continuously running systems, the hybrid system's batteries can store sufficient energy to meet the evening's requirements.
Operating modes of hybrid solar power stations
A hybrid solar power station for a home operates in various modes depending on external and internal conditions.
Autonomous Mode
This mode is implemented on sunny days with average energy consumption. The station's operation results in providing electricity for household appliances, heating, and other systems, as well as transferring excess energy to battery storage. When the batteries are fully charged, surplus electricity is fed back to the grid under the Green Tariff program
Parallel Grid Connection
During prolonged overcast weather, the hybrid station may struggle to meet the household's energy needs in autonomous mode. When the battery charge is depleted, there is an automatic switch to the main power grid.
Backup Mode
This option is realized when during daylight hours, nearly all the energy generated by the panels is fed back to the grid under the Green Tariff program and used for battery charging. In the evening and at night, the energy supply to the house is entirely provided by the battery storage without switching to the stationary grid.
Components of a Hybrid Solar Power Station
During the project development, the system is modeled to include the following components:
- Solar modules..
Their purpose is to generate direct current. The number of modules is determined on an individual basis, depending on the project's calculated parameters. - Hybrid inverter..
Depending on the planned station's capacity, either a single inverter or several parallel-connected hybrid devices are installed to convert the solar panels' direct current into alternating current for the home's energy system. - Battery storage..
For the safe operation of energy storage, batteries are installed in a separate room, housing the hybrid inverter, automation, and protective equipment. - Charge controller..
An additional device ensures a timely response to the decrease in battery charge levels and the achievement of maximum indicators.
Installations are customized based on individual requirements, taking into account energy consumption calculations, the required power reserve, the characteristics of surfaces for mounting station elements – inclination angle, degree of illumination in sunny weather. The result of a professional approach is a comfortable, stable power supply regardless of seasonal changes and time of day.
