According to the preliminary data of the Energy Authority, at the end of 2023, Finland had approximately 1,000 MW of installed solar power production capacity, 936 MW of which was micro-generation and 50 MW from industrial-scale power plants. Unconnected capacity totalled approximately 23 MW.
The total capacity increased by more than 300 MW over the year. According to the preliminary data of the Energy Authority, at the end of 2023, Finland had approximately 1,000 MW of installed solar power production capacity, 936 MW of which was micro-generation and 50 MW from industrial-scale power plants.
In addition, Finland's transmission system operator Fingrid has received wind and solar power connection enquiries amounting to a total capacity of over 100 megawatts. Fingrid assesses that by 2030, the overall solar power plant capacity in Finland may climb to seven gigawatts.
In 2015, the Kaleva Media printing plant in Oulu became the most powerful photovoltaic solar plant in Finland, with 1,604 solar photovoltaic (PV) units on its roof. Although the city of Oulu, located near the Arctic Circle, has only two hours of weak sunlight in December, the photovoltaic cells work almost around the clock in the summer.
“A 5G base station is generally expected to consume roughly three times as much power as a 4G base station. And more 5G base stations are needed to cover the same area,” -IEEE Spectrum, 5G's Waveform Is a Battery Vampire
Although the absolute value of the power consumption of 5G base stations is increasing, their energy efficiency ratio is much lower than that of 4G stations. In other words, with the same power consumption, the network capacity of 5G will be as dozens of times larger than 4G, so the power consumption per bit is sharply reduced.
Simulation results reveal that more than 50% of the energy is consumed by the computation power at 5G small cell BS's. Moreover, the computation power of 5G small cell BS can approach 800 watt when the massive MIMO (e.g., 128 antennas) is deployed to transmit high volume traffic.
The main factor behind this increase in 5G power consumption is the high power usage of the active antenna unit (AAU). Under a full workload, a single station uses nearly 3700W. This necessitates a number of updates to existing networks, such as more powerful supplies and increased performance output from supporting facilities.
Solar supercapacitors are advanced energy storage devices gaining attention for their efficiency and broad applications. With high energy efficiency, they minimize energy loss, making them ideal for maximizing solar energy utilization.
To connect a solar panel to a supercapacitor, follow these steps: Connect the 2 supercapacitor banks on their respective places on the balance board. All other circuits, including the solar panel, are soldered in the same place. Connect all plus wires (brown) from the solar panel and the capacitors to the positive plate. Connect all minus wires (white) from the solar panel and the capacitors to the negative plate. Put the board in the box, so you can close it.
The applicability of supercapacitors for energy storage extends from large-scale energy grids to portable consumer electronics. Their impressive versatility is evident in their usage in electric vehicles, renewable energy systems, power backup solutions, and even personal devices like smartphones and laptops.
Supercapacitors are suitable for solar charging because they can handle non-stop charging/discharging cycles with different currents and unstable parameters. They last longer than batteries and this device can be used for a very long time. In this project, I decided to use supercapacitors instead of batteries for this reason.
