SOLAR PV BATTERY STORAGE WHY BATTERY AFFORDABILITY IS TRANSFORMING SOLAR POPULARITY Commercial organisations have been slower to adopt battery storage than the domestic solar market, primarily due to storage capabilities and affordability. Yet that’s now changing. The challenges organisations once faced are easily remedied, according to Richard Williams – foremost an engineer - as well as founder and Managing Director of Aztec Solar Energy Ltd, the nationwide engineering-led consultancy and installer of bespoke solar photovoltaic (PV) and battery energy storage systems (BESS). Based at the University of Warwick, Richard has over 30 years in the energy services sector, and below shares his views on how battery storage is transforming a sector’s ability to turn to greener energy solutions. The economic attractiveness of solar energy has accelerated over the last five years, with more businesses adopting it to combat rising energy costs and deliver long-term energy security. Until now, the expense of installations, the difficulties of a retrofit, and lack of energy storage has been a barrier, but that’s now no longer the case. Installing rooftop solar power is one of the best investment opportunities available. Batteries have become much more competitively priced and rather than return the energy harvested to the grid – where you don’t always get the best price – they allow you to store that power and draw on it as needed and accommodate peaks in demand. Batteries can be force charged overnight at lower electricity rates, and the energy used in the day when electricity rates are higher. Even if you already have PV panels, battery storage can be added afterwards. Many are taking this option as the economy of scale with battery production is bringing the prices down and making them a cost- Left: Richard Williams is an engineer, as well as founder and Managing Director of Aztec Solar Energy. effective solution. Batteries have reduced both in cost and in size by at least 40% over the last 5 years. With battery installs growing, whether considering adding battery capacity to an existing PV system or planning a whole new PV and BESS, here are my 7 top tips and key points to help...
