CHOOSE THE BEST CONTROL OPTIONS FOR SOLAR LIGHTING SYSTEMS | Synergy Wave System

While designing a lighting application, with off-grid commercial solar lights, the light operation and control options are at the forefront of thought for any solar designer. Since the lights are not dependent on the grid & only a limited source of power from the sun and the batteries, understanding various lighting requirements and availability of the sun is key to understanding system constraints. Every lighting application has different requirements and there are many custom options to control commercial solar lights. These options allow peak efficiency and specific lighting during times required by a specific project. Every Solar EPC project demands a customised or a mix of control options. The options vary from full intensity dusk to dawn operation, to having the lights operate only a few hours after dusk. Let run over a quick preview of the control options and why each has its own place in a project.

DIFFERENT CONTROL OPTIONS FOR SOLAR LIGHTING SYSTEMS:

  1. DUSK TO DAWN

Dusk to dawn is the most popular run time not because it’s always required but because it is the most commonly known. Dusk to dawn operation means that the light comes on at dusk and operates at full intensity until dawn, which can be up to 13-15 hours later in many locations. The light, hence selected correctly will serve exactly as suggested. Turn on at dusk and turn off at dawn. Since commercially designed lights should be sized according to worst case, this is the longest operation available and uses the most amount of power, requiring the largest solar power assembly and battery backup. Its typically ranked as the best option for solar street lights and some solar parking lot lights.

  • DAT OR SPLIT TIME

Dusk activated timers (DAT) are used when the lights only need to operate a certain time frame after dusk and then can shut off for the remainder of the night. These settings are used for situations such as a business that closes at 10pm and all activity will end by 11pm. Split time is the same as DAT setting but allows for an early morning operation. This type of setting is used in areas where there will be activity before dawn and the lights need to come back on one to two hours beforehand. Leading Solar EPC companies pay attention to these credentials when it comes to proper deployment of solar lights.

  • MOTION & SWITCHES

There are two main reasons to use motion sensors- activity reduces and comes back at various times throughout the night like for shift changes or the area is inactive for a majority of the time and would only need to have illumination for safety or security needs. Both options have their best practices and best situational uses. Motion sensors used for safety and security typically have the lights off and only come on when motion is detected. This is perfect for use with parks that close at dusk, remote areas in a facility or neighbourhood or along perimeters. This caters for a plenty of visibility for people in the area after dark and to raise awareness to those who are looking for trespassers, and the rest of the time the lights are not used. Motion for shift changes or where activity may reduce for a time and then come back around is a great way to utilize motion sensors. In these cases, the systems are set to operate either at a reduced intensity or even off until motion is detected. A perfect option for companies that have multiple shifts such as retirement homes, factories, remote parking lots, etc. other applications that benefit from these setups are solar restroom facilities, solar bus stops, solar mailbox clusters and solar pavilion lights.

  • ADAPTIVE LIGHTING

The technology that is being utilized is an adaptive lighting or dimming features of solar lights. An LED light can run full power for part of the night and then reduce output when lighting isn’t required but still wanted. The solar lights can also have an option of going back to full power if a sensor is activated in some cases. Adaptive lighting options are best used for solar parking lot lights, solar pathway lights, solar street lights for remote areas or residential complexes.

WHY SO MANY OPTIONS?

Unless the lights are necessary for all-night operation as the main roadway, dusk to dawn operation is more rarely required than is initially let on. A point to note about these lights are that they are most expensive option since it’ll require the most amount of solar and battery.
