Which Solar Prices Really Matter To You?

When it comes to solar panels, prices vary considerably. However, when it comes to residential rooftop solar panels, prices are fairly easy to quote. Let’s delve into this… First of all, solar panels are a bit like cell phones — there are many different types that are made of different things and vary considerably in “quality.” The bottom line is, different applications require different types of solar panels. More likely than not, however, you are looking for solar panels for your home or business. But the fact is, most of us aren’t going to buy solar panels directly. Solar Panel Prices for Most of Us For various reasons, the price of installed solar panels is very different in different locations. To actually find out what it would cost to go solar in your area, you need to get connected to local or regional solar installers.

The proportions of energy use and GHG emissions attributable to street lighting ranges among BC communities.

Lighting the Way to Sustainability

For instance, street lighting accounts for 15% of energy use, 38% of energy costs, and 6% of GHGs emitted by the City of Nanaimo’s civic infrastructure [1]. In the District of Squamish, street lighting accounts for just 3.5% of energy use and 1% of GHG emissions [2]. Assessing the potential to reduce energy costs and GHG emissions through retrofitting street-lights is a smart move for local governments to make. Local governments in British Columbia, in cooperation with BC Hydro, have already had tremendous success retrofitting traffic lights: Between 2004 and 2006, 98% of light-controlled intersections in BC were converted to Light Emitting Diode (LED) technology, saving $1.6 million annually in electrical costs [3]. Now, retrofits to street lighting are becoming increasingly common across North America. B.C.' LEDs are not yet economical in all contexts. A Well-Lit City.

Street lighting today Today, street lighting commonly uses high-intensity discharge lamps, often HPS high pressure sodium lamps.

Such lamps provide the greatest amount of photopic illumination for the least consumption of electricity. However when scotopic/photopic light calculations are used, it can been seen how inappropriate HPS lamps are for night lighting. White light sources have been shown to double driver peripheral vision and increase driver brake reaction time at least 25%. When S/P light calculations are used, HPS lamp performance needs to be reduced by a minimum value of 75%. A study comparing metal halide and high-pressure sodium lamps showed that at equal photopic light levels, a street scene illuminated at night by a metal halide lighting system was reliably seen as brighter and safer than the same scene illuminated by a high pressure sodium system.
