Solar Market Outlook in Slovenia
There is a solar power boom in Slovenia and it mirrors the rapid growth of the renewable energy sector in most parts of Europe. In 2019, there were 2,496 solar PV systems that were installed in Slovenia generating a total solar capacity of 31.2 MW. Majority of these PV systems were for residential installations. This was a huge increase from the previous year (2018) bringing an increase of up to 233%.
The significant drop in the price of solar components can be attributed to this growth in the Slovenian solar market. In addition, the support models and lower administrative barriers are also a factor.
The continued effort to push the growth of the country’s solar energy sector has resulted in the generation of 268 GWh of solar energy production or 1.8% of the country’s total energy output. The solar industry in Slovenia is made up of 20 companies that generate an annual income of 100 Million Euros. The solar energy sector is forecasted to continue its growth in the next few years especially with the development of a 6 MW solar park in 2020.
Solar Energy Equipment Supply Capacity in Slovenia
There are a few local suppliers and manufacturers of solar power equipment in Slovenia. However, most of the solar panels and components that are used for solar installations in the country are exported from global and online suppliers.
Top Major Seaports & Logistics in Slovenia
There are several ports in Slovenia providing access to commercial, logistics, and trade activity. These ports are
- the Port of Koper,
- Port of Piran,
- the Port of Izola.
All solar power systems are composed of solar batteries. However, not all solar panel system manufacturers and installers provide one solar battery type. Most of the time they offer different models of batteries. Generally, there are four main types of solar batteries that are paired with residential solar panel systems. The commonly used batteries are Lead-acid batteries, Lithium-ion batteries, Nickel-based batteries, and Flow batteries. Each of these solar batteries has its own characteristics. But among the four types, the most commonly used is the lead-acid batteries, and this type of battery also comes with different variations.
For today’s article, we will discuss one of the lead-acid battery types, which is the Gel battery.
What is Gel Battery?
A gel battery is a common type of sealed lead-acid battery. The major difference between gel batteries among the other lead-acid options is the material inside. Generally, a gel battery is made up of silica in its inner electrolyte mixture, which is responsible for producing a gel-like substance. Among other lead-acid batteries, gel batteries produce more power. Besides, this battery is valve-regulated, low maintenance, extremely robust, and versatile.
Since the battery is also “sealed”, it does not require water level monitoring unlike standard lead-acid options, plus it does not expel gas. It only produces few fumes so it’s ideal to use in any place without much ventilation. These factors make it a safer option for solar panel systems than other traditional lead-acid options.
Advantages and Disadvantages of Gel batteries
Gel Batteries are becoming increasingly popular when it comes to solar battery choice due to their several advantages and minimal disadvantages.
- It is ideal for deep cycle applications and the battery life span is ranging between 500 to 5000 cycles.
- It does not require any high maintenance, unlike other batteries.
- Since it produces a gel-like structure, there will be no spill.
- It has minimal corrosion making it compatible with sensitive electronic devices
- Rugged and vibration-resistant
- Safe option to choose. You’re less likely to suffer from sulphuric acid burns.
- Among the other lead-acid batteries, it has the most expensive initial cost.
- Water cannot be refilled if overcharging happens.
- You are required to use special chargers and regulators.
- Hot temperatures can adversely affect the acid, making the gel hard and may shrink away from plates.
Conclusion: Is it Good to Partner Gel Batteries with Solar Panels?
When it comes to solar panels, the most debated type of battery to partnered with solar panels are the Gel battery and AGM batteries. However, not all solar installations are identical, and there are several factors such as climate and discharge demands to consider when choosing what’s the best battery.
If you’re going to observe, gel batteries remain on top as they provide many benefits to solar users for long-term energy storage. Although gel battery is the most expensive among the lead-acid batteries, it is free from high maintenance, making it still an ideal battery for solar users, particularly for smaller solar projects.
On the other side, for most residential solar panel installation that requires high energy demand to power its entire household, you may consider exploring lithium-ion batteries like the Tesla Powerwall to cover all the high energy input from a solar panel system.
