The Visual Design Tools are a set of web based tools that allow users to analyze many common lighting scenarios and view photometric files. The Design Tools can be used to quickly calculate scenarios with simple geometries where inter-reflected light will not significantly affect the resulting illuminance.
Detailed Instructions for the System Sizing Estimator. Step 1 is to calculate the daily WattHour usage of each item. This is done by multiplying the item wattage by the number of hours used each day. The wattage of a UL listed/approved appliance can usually be found near the AC power cord.
I tried to use this calculator for sizing solar panels in hybrid system for micro GSM BTS, but size of invertor is too big for total load of 500 W. For total load of 500 W with operational time 24 h per day, calculator gives size of invertor about 555 KW. I do not understand why. I guess there is mistake in cell which shows KW. Regards,

The Application of Solar Powered LED Street Lighting • LED lighting offers high efficiency, long operating life and low voltage operation which ideal for solar • Solar street lights were initially used in remote locations and disaster prone areas • As LED efficacy and light output have improved, they are becoming mainstream
(1) Calculate Lamp watt for street Light Pole: Calculate Lamp Lumen for street Light Pole having Road width of 7 meter, distance between two Pole is 50 meter, Maintenance factor is 0.9, Coefficient of utilization factor is 0.29, light pedestrian traffic is medium and Vehicular traffic is very light and Road is concrete road. Solution:
About This Report: LED Road Lighting Design Manual This manual is a vendor‐neutral knowledge management tool prepared by Development Finance International, Inc. and commissioned by Philips Lighting for professional reference by transport, urban, and energy sector professionals.
Street Lighting Design in LightTools 2 How Street Lighting Calculations Are Performed SLU assumes that street lamps are far away from the surface that they illuminate, so their intensity distributions, positions, and orientations are the only required data to calculate the test metrics (in addition to the RTable).

Device in solar LED street light system The solar street lighting system consists of many sections. In this chapter, only the Solar panel, the Battery, the Controller and the Led lights are briefly introduced. 2.1 Solar panel 2.1.1 Working principle The Photovoltaic (PV) cell is composed of at least two layers of the semiconductors
N = 1 for single sided road lighting design and N = 2 for double and staggered sided road lighting design, n = number of lamps used in single luminaire = 1 for road lighting. Coefficient of Utilization (COU) is the ratio of utilized lumen to the installed lumen. And it is obtained from the COU graph recommended by CIE.
The top standard of road lighting design is Rp-8-00 which is published by IES (American Standard). Many parameters shall be considered in road lighting calculations, this post only provide brief of this calculations by both manual and software methods (the following procedure for software only).
