Solar power and battery coordination – Maximize the benefits of solar energy

The combination of a solar power plant and a battery system has become an increasingly popular energy solution. The system allows you to utilize solar energy even when the sun is not shining. At the same time, it provides protection from electricity price spikes and improves energy self-sufficiency.

The operating principle of a solar power plant and battery system

Solar power plants produce electricity during the day, when consumption may be lower than production. The battery stores the excess energy and enables it to be used in the evening and at night. This way, maximum benefit from solar electricity is obtained around the clock.

The system's intelligent control automatically optimizes energy use. It takes into account the exchange price of electricity, consumption forecasts and weather conditions. The battery can also be charged from the grid during times of low electricity prices, which brings additional savings.

Sizing determines profitability

Optimal sizing is key to the profitability of the system. The size of the solar power plant is determined by the energy needs of the property and the available installation area. The following are taken into account when sizing the battery system:

Daily consumption profile
The typical difference between consumption and production determines the required storage capacity. For households, 10-15 kWh is often sufficient. batteries, in business locations, the needs can be significantly higher, up to 1000kWh.

Power requirements
The battery should be able to supply sufficient power during peak consumption. For example, charging an electric car or using high-power devices requires a higher discharge rate from the battery.

Extensibility
It is a good idea to design the system as modular, so that capacity can be increased later as needs change or prices fall.

Technical requirements and compatibility

A functioning whole requires seamless cooperation between components.
The key factors are:

Inverters
New hybridsinverters They can combine solar power and battery control. This optimizes energy flows and enables island operation during power outages. A separate battery inverter can also be connected to the system.

Acoustic technology
Lithium-ion batteries are the most common choice due to their high efficiency and long service life. A battery management system (BMS) ensures safe operation and optimizes battery usage.

Control system
Intelligent control maximizes the benefits of the system. It anticipates fluctuations in production and consumption and optimizes battery use according to the price of electricity.

Economic benefits

The combination of a solar power plant and a battery system offers several economic advantages:

Energy cost management
The system reduces the need for purchased electricity and protects against price spikes. Smart control can take advantage of fluctuations in the electricity exchange price.

Investment subsidies
Companies can receive energy subsidies for purchasing the system. There are also subsidies and a household deduction for installation work available for households.

Property appreciation
A modern energy system increases the value of a property and improves its energy rating, which is a significant advantage when selling.

Practical implementation

It is worth starting the purchase of a solar power plant and battery system with a thorough
by design:

Mapping of energy needs
We analyze the property's consumption profile and determine the optimal system size. We also consider future needs, such as electric car charging stations.

Technical design
We select the most suitable components and plan the installations. We ensure the safety and compliance of the system.

Deployment and optimization
We perform a thorough implementation and optimize the system settings. We guide users to monitor and utilize the system effectively.

Summary

The combination of a solar power plant and a battery is the energy solution of the future. It offers tangible savings and improves energy self-sufficiency. With careful planning and professional implementation, the investment pays for itself and produces benefits for decades.
