THERE ARE several factors driving local, regional, and national electricity distribution towards direct current (DC); the implications of DC lighting are enormous in the paradigm of building Ā power value, the growth of new and renewable technologies, and the positive economic, energy, and environmental impact it yields.Ā Here are the 10 top reasons why it makes senseā¦
- Empower Grid Resiliency ā DC lighting seamlessly connects to renewable DC power sources. According to a Pacific North National Laboratory study, āDC lighting is key component of optimized DC microgrid solutionā
- Risk Management ā mitigate risk of lighting downtime from power failures
- Decrease Carbon Footprint ā reduce carbon emissions equal to the DC load offset, enabling zero energy building objectives
- Optimize Power Control & Costs ā empower strategic load sharing options
- Convenience with Lamps & Bulbs ā LED fixtures include DC LED lamps or bulbs, providing significant savings and convenience for installers and end-users
- Dependability & Stability ā consistent, low noise
- Greater Efficiency ā up to 15% more efficientĀ
- Decrease Costs ā DC LEDs yield cooler operations,Ā reducing the potential building heat load, as well as offering higher efficiency and long lamp life Ā
- Expandability ā add DC devices and systems to create a smart network
- Proven Technologies ā many blue-chip companies and power utilities are currently using DC micro-grids
Hi, I am designing a pv system that should provide enough power to iluminate my idnustrial facility. What is the main difference between 24VDC,48VDC and 125VDC if it comes to light efficiency? Which should i choose?
Hello Jakub, There are no efficiency or performance variances between 24DC, 48DC and 125DC voltages; the preference leans toward the Direct-Coupled (DC-to-DC) connecting source or project voltage specified. For example, most solar PV is 24DC or 48DC, depending on manufacturer & array/panel model – so the DC lighting voltage would generally be specified to meet the primary voltage of the Direct-Coupled source (i.e. the solar panels and/or battery storage). Hope this helps.
