FAQS about Economic benefits of photovoltaic energy storage batteries

Are solar energy and battery storage a good investment?

Solar energy and battery storage support employment in good quality and high productivity jobs, with an average GVA per job of £88,800 in 2024, over 40% larger than the UK average. Solar energy and battery storage contribute to economic activity across the UK while supporting the energy transition.

What is the economic impact of solar & battery storage?

The main source of economic impact came from the construction of utility scale projects, and annual residential and commercial installations. Solar and battery storage contribute to employment in relatively high productivity jobs.

How do solar energy and battery storage support economic activity?

Solar energy and battery storage support economic activity in several ways, as shown below. At the end of 2024 the UK had a total 20 GW of solar capacity and 7.5 GW of battery storage capacity. Over the period to 2035, activity across both technologies could expand significantly.

Do solar energy and battery storage contribute to economic activity across the UK?

Solar energy and battery storage contribute to economic activity across the UK while supporting the energy transition. This study provides an initial estimate of the overall economic contribution made by solar and battery storage deployment across the UK.

Why do we need more solar & battery storage?

Increasing the UK’s solar and battery storage capacity are key to transitioning away from fossil fuels and the achievement of a clean energy system. Greater use of solar and battery storage will be needed for the Government to meet its clean power objectives by 2030, and for the UK to meet its statutory net-zero targets by 2050.

Are battery storage projects financially viable?

Different countries have various schemes, like feed-in tariffs or grants, which can significantly impact the financial viability of battery storage projects. Market trends indicate a continuing decrease in the cost of battery storage, making it an increasingly viable option for both grid and off-grid applications.
