Over the past decade, the island has embarked on radical reforms to deliver a power system that can operate with a penetration of 75% of non-synchronous generation (wind, HVDC interconnectors and solar) at any one time. This metric is called SNSP – system non-synchronous penetration level. A key step in achieving 75% is finalising the procurement approach for system (or ancillary) services, with major reforms recently consulted on. The result: a positive outlook for batteries.
Simply put, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity. Solar panels actually comprise many, smaller units called photovoltaic cells. (Photovoltaic simply means they convert sunlight into electricity.) Many cells linked together make up a solar panel.
