How EnGoPlanet solar street light can be good for universities and schools?
University's executive leadership and facility managers are now placing enormous value on sustainability projects that save energy and broaden environmental awareness of global warming beyond the classroom. These projects offer colleges and universities a number of ancillary benefits beyond the obvious goal of reducing carbon emissions, and often save money in the long run as well. Chief among these benefits is reducing the cost of energy. Additionally, since lighting costs often make up a large portion of a university's energy spend, renewable lighting solutions should be explored. With extensive grounds and numerous buildings to illuminate, the lighting bills can add up quickly. Solar panel technologies have made it possible for campuses to significantly decrease lighting installation costs and eliminate the electricity bills associated with outdoor lighting. The economic appeal of solar lighting will only increase as the prices of solar modules, batteries and LED lighting continue to decline. LED technology has become extremely efficient and has a long product life when compared with traditional types of lighting such as sodium vapor and fluorescent lighting, therefore significantly decreasing operations and maintenance costs, while continuing to deliver a bright, crisp white light that does not fade in intensity. Solar-powered lights also provide high quality light for more than five days without a single ray of light due to advancements in battery technology. Solar lighting is a public demonstration of an iuniversity's commitment to a "green" orientation, allowing a university to project an environmentally conscious message throughout the campus When Odessa College in Odessa, Texas, an 80-acre campus with more than 11,000 students, chose to install solar lighting instead of traditional grid-tied lights, the university executive team's main concern was with the safety of students and staff walking to and from classes across a sprawling campus. In particular, students felt unsafe in the parking lots and on their walks to campus, prompting the search for a cost-effective solution. However, the existing buildings and landscape also played a large role in the ultimate decision to go solar as the installation of grid-tied lighting would have required prohibitively expensive trenching and wiring. Since solar outdoor lighting does not require a connection to the electrical grid, the advantages of solar lights were immediately apparent. Additionally, the money saved was a pleasant upside that will continue for years to come. Odessa was able to save around 20 percent of the cost of a new system at the time of installation due to the avoidance of the wiring and trenching needed for traditional grid-tied lights. Because the systems are 100 percent solar powered, the lack of electricity bills is saving the university more than $8,000 per year, without even taking into consideration the savings on operations and maintenance costs. In addition, EnGoPlanet Solar street light has many useful features that students, professors and guests of university or school can use, such as USB charging ports, Wireless Charging, bench. The conlusion is that reliability that EnGoPlanet Solar street light offer really help students feel safe at all times in and around their campus.
For Solar Street light, How to calculate the rating for LEDs used, battery and the solar module itself?
It's a difficult thing to calculate. You need: worse case number of hours of full sun per day Number of hours the batteries have to run the lights on days without sun. The problem is, you can have perhaps 3 days without sun due to a storm. that means the batteries have to power the light for that number of hours. And then when you get, say, 6 hours of sun, the solar panels have to be powerful enough to recharge that bank of batteries in that time. So, you have to set all of these parameters, else you wind up with several hundreds of watts of solar panel for a 40 watt light and a huge battery. Take an example. An ordinary auto battery can store about 1 kW-hour of energy. To operate the 40 watt light for 70 hours, means you need a 2800 kW-hour of storage, or 3 auto batteries. To recharge that 2800 kW-hours in 6 hours, you need 500 watts of solar panel. And that does not count losses. .
