What is solar PV battery storage?

Solar batteries store the surplus energy produced during daylight for use during periods without sunlight (e.g. at night, during power outages). Considering the cost implications of your solar panel system means understanding the role and value of solar PV battery storage.

How much does a solar PV system cost?

The cost of a home solar PV system starts from around €3500 for a basic installation, with SEAI grant aid started from €900 up to €2,100 subject to the year your home was built. Solar PV is intended to be an investment that, once paid for, will save its owner money by generating free electricity during daylight hours.

How are PV & storage prices calculated?

PV systems are quoted in direct current (DC) terms; inverter prices are converted by DC-to-alternating current (AC) ratios; storage systems are quoted in terms of kilowatt-hours or megawatt-hours (kWh or MWh) of storage or the number of hours of storage at peak capacity. Values are inflation-adjusted using the CPI (2019).
