With advances in high power / high efficiency LED lighting, area lighting is no longer reliant on cable runs and the proximity of electrical infrastructure. Often it is more cost effective to use renewable energy such as solar to power lighting systems even if grid power is readily available when considering costs such as installation, electrical authority certification, min. monthly electrical service charges etc. Integrated lighting control programs allow for timed on-off schedules based on dusk or dawn reference points year-round.
Solar Signals has been providing reliable lighting solutions for years in the real world where it is not always sunny and not always tropical.
