ABSTRACT
Up until 2007 solar-powered lighting systems were not feasible due to equipment cost factors. Efficiencies in PV panel production, batteries, etc., have now made it more feasible to use solar-powered lighting systems when getting grid power to the needed site may cost the end user substantial amounts of money. Some site factors included, but not limited to, are distance to run grid power, on-site existing buried utilities infrastructure, and costs of repair to existing drive/parking surfaces to provide grid power, and also, security of individually powered lighting poles, instead of a single grid power elimination point.
