Getting a jump on proposed UL 6703A standard
Chamelic is a spin-out company from the Faculty of Engineering at the University of Leeds. Chamelic Ltd was established in February 2006 to exploit innovative chemicals discovered and developed at the Institute Particle Science and Engineering (IPSE).
Sade's idea was to eliminate the need for masts or poles to secure a solar array to concrete foundations. Instead, the tracker would use a ballast pan filled with dirt, gravel or sand.
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.

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.

What if you could maximize the Ground Coverage Ratio (GCR) on your next project and not have to worry about the complicated variables that come with a tracker system? With a low tilt and clearance design, Dahlia® has the highest GCR of any fixed-tilt system in the marketplace. The system is available in three tilt options (7.5, 10 and 12.5 degrees) and designed to accommodate any sized PV module. The lightweight system is engineered with fewer components, several of which are shipped to job sites pre-assembled. This design feature reduces freight costs and rapidly trims the amount of on-site installation time required to complete construction. Maximizing PV coverage on a site can lead to an increase of production, which creates greater financial return for project owners. Over 100 MW of Dahlia® projects have been deployed across the United States, in regions of variable snow and wind loads. How much can Dahlia® cover and save you on your next project?
