Photovoltaic installations are an increasingly popular source of energy. Problems arise when the energy produced is not used to its full potential, as demand varies according to the time of day or the year. Where does the unused energy go? Back to the grid, theoretically we can draw up to 80 per cent from the grid, although in practice this figure can be much lower. With help comes home energy storage, which allows producers to store the energy generated and use it at the right time. These systems are ideal for homes, places where it is difficult to connect to the grid and places prone to breakdowns that cause frequent power outages.

The main advantage of energy storage is that producers can non-destructively harvest the energy generated by their installations. On balance, there is at least a 20% loss of energy generated by the panels, which is consumed by the utility. Energy storage can compensate for these losses.

The development of the energy storage market depends on the need to stabilise the grid, and congestion is becoming an increasing problem. Grid instability is a problem for the largest power companies in the energy market. Moreover, large energy companies are seeking to increase their share in the renewable energy sector, as it will represent a huge economic potential in the near future.

Energy generated and stored with backyard energy storage eliminates the problem of transmission losses and the need for continuous investment in decentralised infrastructure, making energy storage the best solution for today’s generation customers and Poland’s largest energy companies.
