Application scenarios of solar energy systems in hybrid residences

Hybrid residential solar systems, by integrating photovoltaic power generation and thermal energy utilization technologies, can flexibly adapt to the energy demands of different residential scenarios. Their application scenarios can be expanded from the following dimensions:

1. Daily electricity supplementation and self-sufficiency

Basic power coverage: In single-family residences, the system can give priority to meeting the basic power demands such as lighting, home appliances, and charging equipment. Solar energy is converted into electricity through photovoltaic panels and stored in battery packs or directly connected to the household power grid, reducing reliance on the municipal power grid.

Peak-valley electricity price optimization: During peak electricity price periods, the system automatically switches to solar power supply to reduce electricity costs. At night or on rainy days, it seamlessly switches to the power grid or backup power supply to achieve an economic balance in energy usage.

Emergency backup power supply: Systems equipped with energy storage devices can supply power to critical loads such as refrigerators and communication equipment during power outages, enhancing household energy security. It is particularly suitable for areas with unstable power grids or frequent natural disasters.

2. Hot water supply and space heating

Solar water heating system: It absorbs solar radiation heat through collectors, heats domestic water and stores it in an insulated water tank to meet daily hot water needs such as bathing and washing dishes. In areas with abundant sunlight, it can completely replace traditional electric water heaters or gas water heaters.

Integrated auxiliary heating: In cold regions, the system can be combined with floor heating, radiators or air source heat pumps to heat the circulating medium (such as water or antifreeze) through solar energy, providing basic heating for the interior and reducing energy consumption for winter heating.

Seasonal regulation: In summer, prioritize meeting the demand for hot water. Excess heat can be dissipated or used for heating the swimming pool. In winter, the focus is on heating, forming a dynamic energy distribution mechanism.

3. Multi-family residences and community-level applications

Apartment building shared system: In high-rise residential buildings or apartments, centralized solar systems can supply power to public areas such as corridors, elevators, and parking lots, or distribute electricity to each household through individual metering technology, reducing public energy consumption costs.

Community microgrid: Within residential communities, hybrid systems can complement wind power generation, biomass energy, etc., to build independent microgrids, achieving energy self-sufficiency and reducing long-distance transmission losses.

Shared energy storage facilities: Centralized energy storage devices are set up within the community to balance peak and off-peak electricity consumption for each household, enhance overall energy utilization efficiency, and provide green power for electric vehicle charging piles at the same time.

4. Green buildings and zero-energy residences

Passive design synergy: Combined with passive technologies such as high-insulation walls and double-glazed Windows, hybrid solar systems can further reduce residential energy consumption and help achieve zero or near-zero energy consumption goals.

Building Integration (BIPV) : Integrating photovoltaic panels into roofs, curtain walls or shading facilities, it not only generates electricity but also serves architectural functions, enhancing aesthetics and space utilization. It is suitable for modern low-carbon residential design.

Intelligent energy management: By using Internet of Things (iot) technology to monitor data such as light, temperature, and power load in real time, the system automatically adjusts power generation, energy storage, and power consumption strategies, optimizing the energy flow path.

5. Remote areas and off-grid scenarios

In areas without power grid coverage: In remote regions such as mountainous areas and islands, hybrid systems can operate independently, providing stable electricity and hot water for residences, replacing high-cost diesel generators and reducing environmental pollution.

Mobile home applications: Equip mobile homes such as recreational vehicles and yachts with lightweight solar modules, combined with portable energy storage devices, to meet the basic energy needs during outdoor travel.

Agricultural auxiliary facilities: In rural residences, the system can supply power to greenhouse lighting, irrigation pumps, livestock breeding equipment, etc., promoting the green transformation of agricultural and residential energy.

6. Special demand scenarios

Power supply for high-energy-consuming equipment: Provide partial electricity for high-power devices such as air conditioners and ground source heat pumps, reduce reliance on traditional energy sources, and lower long-term operating costs.

Environmental protection concept practice: Meeting the owners' pursuit of sustainable living, reducing carbon emissions through solar energy systems, and enhancing the market value and living experience of residential properties.

Policy compliance: In regions where new buildings are required to be equipped with renewable energy, hybrid systems can flexibly meet regulatory requirements and avoid additional renovation costs.

The core advantage of the hybrid residential solar system lies in its flexibility and adaptability. It can provide customized solutions based on different climates, building types and energy demands, promoting the transformation of residential energy consumption towards clean, efficient and autonomous directions.
