Perimeter Lighting with Central Solar @ Gwarinpa, Abuja
Notice there is no solar panel on the pole? Most solar street and perimeter lighting suffer from insufficient charge hence they donâ€™t last. This is caused by the fact that due to weight and space constraint, enough solar PV is not used plus typical charge controllers used are the cheap 10A on/off type which not only kills batteries but does not even get the job done. Centralizing the solar array and running either AC* or DC with suitably sized cables ensures that quality charge controllers are used and PV is appropriately sized.
