17 10 2012 - Stand-alone Solar


This is the fourth chapter of our Solar Light Fitting Tutorials. Up until now we have looked at the “Panel”, the “Battery” and the “Heart” of the system or the ECB. After having looked at the important components it is time to look at the system as a whole, and the advantages of Stand-alone Solar Lighting

When we hear the word “Solar” many times we think of solar panels lined up in rows, extending off into the distance. We might also think of small roof top installations that heat water or that feed electricity into the greater grid. The “big” and “small” installation have one major thing in common, apart from being a good idea, which is that they both need to be connected to a larger “grid” to be effective.

Mareco Luce’s Urban Solar products have been designed to be “Off-grid” or stand-alone. They don’t feed the grid, yet they don’t draw off the grid either. This is particularly recommended in areas where:

  • the electrical grid is difficult of impossible to access
  • costs of laying cables are high
  • underground checks are time consuming and/or costly
  • location of electrical service provider is unknown
  • copper theft is a problem
  • there is a desire to move towards clean-renewable energy, eg. LEED certification
  • government subsidies are in place

And /or in existing sites where:

  • lighting has not yet been installed
  • cost of disruption to daily activities is high
  • existing lighting is insufficient
  • underground wiring is needing replacement

Occupancy Sensor
A recent improvement to Mareco Luce’s system also allows the client to integrate an occupancy sensor to allow even more efficient power management. We provide the possibility to connect an occupancy sensor to our Urban Solar products, and allow our customers to source their own sensors, or to integrate the Urban Solar products with pre-installed systems.  

Backup Connection
Another additional option is the Grid Connection. This might be regarded as a contradiction to all of what we have described above, but it is a necessity in certain situations.
For example:

  • the location of the project may not guarantee enough solar radiation (eg. shaded areas)
  • the electrical grid is not difficult or costly to connect to
  • products are located in “high profile” urban areas eg. high streets, central squares, public parks, government buildings.

Mareco Luce’s Urban Solar fixtures are designed to switch over to the grid when the power management system cannot guarantee a set level of luminosity from the LEDs. The fixtures draw off the grid at night, but do not charge into the grid during the day.
