Energisers with integrated high capacity solar panels. Many solar energisers are low in power and/or utilise solar panels which are inadequate to keep the battery charged. The Fire Drake energisers operate at popular power levels, suitable for a range of applications. The energisers have been developed specifically for the UK climate and feature high efficiency solar panels carefully matched to replace the battery energy used while operating, as quickly as possible. A battery charger is also included to help keep the battery charged when sunlight is in short supply.
