The purpose of the City of Oakland Street Light Design Manual is to assist public and private designers in the design and construction of street lighting, and also to assure design uniformity governing City of Oakland's street lighting warrants. The Street Light Design Manual is to be used as a companion document in conjunction with
Each solar calculator takes time and effort from our team and we ask you to share about them with your friends to use them free of cost. However, the page will automatically get unlocked in 5 minutes.
I have seen the excel sheet, you have prepared for design of solar panel, inverter and battery bank and it is awesome. Here, my application is little different on solar water heater. I want to maintain the 70 C temperature of 50 liters (approx) water using 500 W DC heater for 24×7.
Able to calculate the battery =120 Hours x 0.35 mA = 42 Ah. (available commercially battery = 50 Ah) with to be longtime support = 142 hours (support to rains or dark condition) by ON the light 24 hours a day. Solar Street Light Design Calculation. Principles calculations represented by five hours per day for charging via solar cells.
the intensity of solar insolation over a year, strongly depend on the latitude and weather conditions of the place. The heat energy produced by a solar collector depends on the type and design of the collector. Several types of solar collectors both theoretically and experimentally have been investigated and formulae for the calculation of

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).
Spacingrow = Room Length ÷ (Number of Fixtures/Row - 1/3) Spacingcolumn = Room Width ÷ (Number of Fixtures/Column -1/3) If the resulting number of fixtures does not equal the originally calculated number, calculate impact on the designed light level: % Design Light Level = Actual No. of Fixtures ÷ Originally Calculated No. of Fixtures
The right configuration will not only make the work of the solar LED street lamp system more stable, but also lower the cost. The calculation method of solar LED street light system configuration is related to the following factors

1. Determine what is power consumption of your street light. The first step in designing a solar street light system is to find out the total power and energy consumption of LED light and other parts that will need to be supplied by solar power, such as WiFi, Camera etc. need to be supplied by the solar PV system.
Say the area requiring lighting calls for 5 lights. If your solar lighting project is a total of $19,000 and bringing in electric for standard lighting is $10250 for example, you would need the following formula to determine the ROI:
