Roofscreen Solar Panel Racking

Roofscreen has diversified their product line into the solar panel industry. The Roofscreen solar panel racking system can be scaled up easily, has a low parts count and ships with with drawings that are certified by a structural engineer. This racking system is geared towards commercial and industrial rooftops, which traditionally have obstacles such as vents and drains. The Roofscreen due to its height can clear the typical obstacles other racking systems can’t therefore increasing the space solar panels can be installed on top of commercial and industrial roofs. One of the nicest features is if the roof needs to be repaired in the future, the Roofscreen can be completely or partially dismantled and reinstalled at a later time. There are multiple waterproof roof flashing made for the most common commercial and industrial roofs. When working with Roofscreen, not only do you get the solar panel racking product but a service of AutoCAD designing to the unique specifications of your roof is also included when you order a Roofscreen solar panel mounting system. The Roofscreen can also be used in high wind speeds, the design of the system makes the system stronger when the wind load is high. Lately many new products are being introduced in the commercial and industrial solar panel mounting market. Why do you think this...

Intergrated Inverter DC/AC Disconnects

Disconnects for safety reasons rapidly disconnect from a power source. Disconnects are on / off switches and are required by National Electrical Code (NEC). With a solar power system for your system to pass inspection and meet all UL and NEC requirements your system must have a DC/AC Disconnects. Over the last few years inverter manufactures have been integrating dc, ac or DC & AC disconnects right into the inverter or as an external unit. Many inspectors are familiar with integrated DC / AC disconnects which is a good sign of the wide acceptance. The picture above shows a SMA Sunny Boy Inverter with an integrated disconnect, a knob style switch quickly shuts off the power in case of an...

Top 7 Myths of Solar Electricity

The US Department of Energy Efficiency and Renewable Energy released an interesting article on the common myths of solar electricity (photovoltaics). Solar Power has been around for decades, although people still believe its an inferior technology which is not even close to true. The myths most consumers have are mind are the following: Myth #1 – Solar Electricity cannot serve the needs of the US or the world. Myth #2 – Today, Solar Electricity can do everything for everyone. Myth #3 – Solar Energy cannot offset greenhouse gases Myth #4 – Manufacturing Solar Panels creates pollution Myth #5 – Solar Electricity is merely a hobby and only appealing to small niche markets. Myth #6 – A solar power system is just too expensive, you can’t get much energy out of a system. Myth #7 – Solar Panels and system equipment is as good as it can get, there is no need for additional research and development. Why do you think people have these myths in mind when they think about solar...

PanelClaw makes mounting solar on a flat roof a snap.

PanelClaw, a manufacturer of solar panel mounting systems, has launched a new product line called the Polar Bear. The Polar Bear is a easy to install non-rail based, ballasted mounting system that is designed to save money and time for everyone involved in the installation process. Polar Bear mounting system was independently tested in a wind tunnel at the Colorado State University and was beta tested at three large scale commerical installations, so the product has some real world field testing under it’s belt. Three people can install 16 solar panels under 20 mintues with the Polar Bear mouting system. The slip sheets and ground lugs come pre-installed which saves time in the installation process. Best of all this innovative solar photovotaic mounting system is made in the good ole...

U.S. Department of Energy Installs Solar Panels

The U.S. Department of Energy (D.O.E) finally put their money where their mouth is and installed a 205 kilowatt (kW) solar electric system on their headquarters in Washington D.C. The system will generate 222,000 kilowatt hours (kWh) of electricity per year. So it seems like the D.O.E. are a bunch of slow spokes when it comes to adopting new energy technology, why did it take them so long to install solar panels, when many homes and businesses around the world have been harnessing the power of the sun? Well the D.O.E. invests very little in research & development compared to nuclear bombs which is where most of the yearly D.O.E. budget is allocated to. Our own department of energy is lagging behind when it comes to renewable energy, this is one of the root causes of why the American energy policy is very flawed. Isn’t it ironic that the D.O.E logo has a wind turbine and sun in it’s...
