How do you choose the right energy storage for your photovoltaic system?

In recent years, the growing interest in renewable energy has led to an increase in the popularity of installing photovoltaic systems. Photovoltaics are not only an environmentally friendly way of generating energy, but also help to significantly reduce electricity bills. However, in order to fully exploit the potential of solar energy, it is also necessary to focus on storing the excess electricity produced. To this end, proper energy storage is a key element to help make use of surplus energy in times of less sunshine or at night. In this article, we discuss how to properly select the right energy storage for your photovoltaic system to maximise the potential of green energy

Energy storage – what is it and do you need it?

Energy storage is a system or device used to store energy in various forms for future use. It is an important solution in the context of the energy transition and the development of renewable energy sources such as solar energy.

A factor that makes energy storage important is the volatility and variability of energy production from renewable sources. Solar energy is only available during the day and, as a result, energy production can be erratic and inconsistent with demand.

Energy storages are needed because they make it possible to increase the efficiency and flexibility of energy systems and reduce dependence on traditional, non-environmental energy sources. They also help to reduce greenhouse gas emissions, contributing to the fight against climate change.

What to consider when choosing an energy storage for photovoltaics?

Choosing the right energy storage for a photovoltaic system is crucial to the efficiency of the entire system. Below, we will outline the most important things to look out for when selecting energy storage for photovoltaics to ensure optimal use of solar energy and maximise the economic benefits.

Types of energy storage

Before choosing an energy storage facility, it is worthwhile to familiarise yourself with the different solutions available. There are several types of energy storage on the market today, each with its own unique features. Among the most popular solutions is the battery, which allows us to store electricity efficiently and use it when we need it.

Energy storage capacity

When deciding on a particular energy storage, it is essential to determine the exact level of capacity required. The most important aspect is to analyse the average daily energy production of our photovoltaic system and determine our energy consumption. By estimating how much energy we need to store for a sunless period, we can avoid purchasing storage with too little or too much capacity, which can lead to wasted resources.

Capacity and lifetime

Another important factor is to check the performance and service life of the energy storage. Energy storage technology is developing at a rapid pace, so it is worth betting on modern solutions that provide higher efficiency. A longer storage life will save on the costs associated with replacing batteries or the entire system in the future.

Integration into a photovoltaic system

The best choice will be a storage facility that works perfectly with our photovoltaic system. It is important to check that our photovoltaic system is compatible with the energy storage in question. Some solutions may require special inverters or additional modifications that can increase the cost of the whole system.

Costs and return on investment

The price of energy storage is also an important factor. Purchase, installation and maintenance costs can vary significantly depending on the technology chosen. A comparative analysis of the various options should be carried out and the expected return on investment taken into account. Sometimes it is better to invest a little more at the beginning to save on long-term running costs.

LiFePO4 batteries for photovoltaics – the best energy storage

When deciding on the right energy storage for your photovoltaic system, it is worth betting on the solutions offered by the Kon-TEC brand. It is a manufacturer of high-quality LiFePO4 batteries, which are characterised by outstanding performance, durability and service life. Kon-TEC batteries are compatible with inverters from the majority of leading brands, and thanks to the fact that they are available both as individual units and in modular combinations, they can be easily adapted to the needs of your photovoltaic installation.

Choosing the right energy storage for a photovoltaic system can be crucial to the efficiency and cost-effectiveness of the overall solution. By choosing the right energy storage, we can maximise the potential of our photovoltaic system, enjoying not only savings on electricity bills, but also reducing harmful gas emissions, thus caring for the future of our planet.
