From a materials perspective, racking represents roughly 5-10% of the system cost. That said, the labor required to install the modules on the racking system costs twice as much as the racking material involved and can account for up to 66% of the total installed cost of a system. According to expert industry analysts, the speed and ease of installation for the racking system can directly impact roughly 40% of the total installed cost.
Stephen Colvin is Vice President of Marketing for Mersen's North American Electrical Protection interests. His responsibilities comprise management of all aspects of the marketing department including product line management, marketing communications, public relations and market research.
Data loggers can provide valuable information for nearly every aspect and scale of green design. For example, a facilities manager can monitor temperature in a fifteen-story office building over the summer to check whether the fans in the building's cooling tower need adjustment.
Renewable energy will be a significant component of our future energy picture -- distributed generation from PVs to wind turbines and storage systems for electricity and cooling. These systems will increasingly be installed in our homes, together with smart electricity meters.
SolarBOS was the first company to build a combiner box around a flexible platform where the system integrator could specify the number of fuses and enclosure rating. While this seems pretty simple in hindsight, back in 2004 this was brand new and allowed integrators a lot of flexibility on the design of the DC side of the project.
To begin to make changes, it is important to know how much energy you are currently using. If you don't save your gas and electricity bills, it is a good idea to start doing so now.
Choosing the right hardware is among the most important decisions that you will make when beginning an energy audit / inspection application.
Take a moment to program in your electric utility rate ($ per kwh) and the unit will tell you the total cost of running the appliance during the time of monitoring. Push the "Cost" button again and it will calculate the cost per day ... another button push = cost per month and one more push forecasts the cost per year.
Spending a few minutes with this software can provide as much education as reading several books on energy saving construction ... in real terms ... with your own house as an example. The tips provided along the way are very helpful and having the "Energy Efficient House" costs listed gives you a great target to shoot for.
The Submeter shows you where electrical power goes in your apartment building, office, marina, or RV park! Do you have a "smart house"? A submeter can track all of your branch circuits and report power anomalies. Read and control from any internet connection.

Sierra was the first to introduce a combination volumetric vortex and multivariable mass flow meter in 1997. Today, Sierra's completely redesigned InnovaMass® iSeries™ 240i/241i builds on two decades of success measuring five process variables for gas, liquid and steam with one connection. Now, with the latest hyper-fast microprocessors, robust software applications, field diagnostic and adjustment capability, and a new state-of-the-art flow calibration facility, Sierra's vortex iSeries delivers precision, performance, and application flexibility never before possible.
