first liquid cooled LED light bulb

The two major problems with LED lights are they are very directional light source and the LED chips can get hot when operating for a long time which can potentially shorten lifetime if the LED bulb is not cooled properly. Eternaleds introduced the first liquid cooled LED bulb called the HydraLux-4 which uses a fluid inside the LED bulb to not only cool the bulb but disperse the light 360 degrees around the bulb. The 4 watt bulb is equivalent 24 watt incandescent bulb and is offered in two colors, Warm White and Daylight White. By the end of this year the company is expected to release a 8 watt, 12 watt and 16 watt versions for people who want more light output. The HydraLux-4 only cosst $1.75 per year to operate and over the lifetime of the bulb can save up to $157 in electric and replacement costs compared to an incandescent. what do you think about the Eternaled...

sharp’s new high power solar panels

Sharp has recently announced their new high output 230w (NU-U230F3) and 235w (NU-U235F1) solar panels are available for purchase this month. The Sharp 230w solar panel combines both performance and aesthetics by offering a high output and a black frame and backsheet to meet the high expectations of residential customers. The 235w solar panel offered by Sharp is geared towards commercial systems and includes a white backsheet to reflect more light into the solar cells which increases power output. Sharp solar consistently improves their product line by considering customer feedback. Sharp solar offers a 25 year warranty on their solar panels, similar to other solar panel manufacturers although Sharp is a reputable brand name and a customer can have confidence in the warranty. check out the spec sheet for the Sharp 230w solar...

products at Intersolar 2009, day two.

Day two at Intersolar 2009 was action packed. I had a really busy day but managed to get you’ll some shots of some really cool products right from the tradeshow floor. A “green” solar panel Symphony Energy has released the first “green” polycrystalline solar panel. Typically solar panels have either a blue or black color to them, although Symphony decided to change up the color for aesthetic reasons. Walking around the trade show floor, I noticed all the solar panels started to look the same. By changing the color of the polycrystalline to green the company made their product standout. Their putting the words “going green” in their product literally. What do you think about green solar panels? Would you put these on your roof? Solar panel security alarm I wrote about Gridlock Solar Security a few days ago, today I got to meet them in person to talk about their advanced solar panel security device. Similar to a burglar alarm, once the alarm has been triggered the unit not only flashes and sends out an annoying siren but contacts the police and dials telephone numbers that you can program the unit with. This is one of the most unique products I saw at the show because it really focuses on reducing a big problem in the industry, solar panel theft. produce electricity and heat water The limitations of solar panels today is there are two different types of systems. photovoltaics generate electricity while solar thermal heat water. What if you can have one system that can both produce electricity and provide you with your hot water needs? PVTherm is doing just that, they’ve created a solar panel that heats water and produces power with the same solar panel! You can maximize surface area by having one system that take cares of two needs. Monster solar panel, ahhhhh! Typically polycrystalline solar panels that are on rooftops are a couple hundred watts but this monster solar panel from Best Solar is 370 watts with a huge footprint. So massive it would be impossible for a couple people to carry this up to a roof. You would need a crane to get this solar panel installed. We asked the Best Solar representative what type of applications this large of a solar panel would be used for and he said that these solar panels are made for utility scale projects since these monster solar panels produce a lot of power and make it more difficult to steal. Intersolar 2009 has been a great trade show so far, we’ve seen a lot of the same but there has been a handful of unique...

products at Intersolar 2009, day one.

We’re here in San Fransisco at Intersolar 2009 dedicated to show you some products that we found interesting on the trade show floor. Let’s take a look at these innovative products that improve performance, installation and aesthetics. Schuco Ballasted Flat Roof Solar Panel Mounting: Installing solar panels on top of a flat commercial roof can be a challenge to not compromise the integrity of the roof since most installations require roof penetrations. Schuco displayed their ballasted solution that holds down solar panels on a flat commercial rooftops with nothing but a simple brick as a weight. Ballasted systems are great for building owners who have warranties on their roofs but who do not want to void their warranties when installing solar panels. Ballasted mounting solutions typically cost more per watt and add more weight to the roof compared standard racking systems. Canadian Solar panel with Clear Backsheet Canadian Solar Incorporated is showing off a solar panel with a clear back sheet. The advantage of using a solar panel with a clear back sheet is light can still penetrate through the solar panel which makes this type of solar panel ideal for applications in which solar panels provide shade, for example a parking structure or canopy. The clear back sheet is on this monocrystalline solar panel is purely an aesthetic feature. Kaco Solar Inverters with iPhone App? Kaco Solar has rebranded to Kaco New Energy and has made recent improvements to their residential grid tie product line. I saw a display at their booth about an iPhone application that can interface with your Kaco grid tie inverter and display the inverter statistics right on your iPhone. It seems like more grid tie inverter companies are starting to bring inverter data to your mobile phone, which is a trend I expect to see adopted by other grid tie inverter manufacturers S-5! expands product line for metal roof attachments S-5! is a company that focuses on developing attachments for metal roofs, they started with standing seam metal roofs. They have recently created a new attachment product to work on metal roofs with a wavy design. The convenient aspect of this attachment is it has a special adhesive that protects the installation from roof leaks by plugging the penetrations made to secure the solar panels on the roof. This allows you to install solar panels on a metal roof painlessly without worrying about a leaky roof in the future. Global Solar Flexible Thin Film Global Solar is leading the space in terms of developing flexible thin film solar panels to charge up electronic devices and battery packs. From what I saw at their...

ascent solar makes efficiency progress

The National Renewable Energy Laboratory (NREL) recently verified that Ascent Solar‘s flexible Copper, Indium, Gallium, Selenide (CIGS) solar panels have an efficiency as high as 10.4% This is great news for flexible solar panels since they continue to get better in terms of how much sunlight they can turn into power. The flexible solar panel that was tested by NREL came right off a Ascent Solar’s production line which puts confidence in Ascent Solar’s ability to manufacturer 10% efficient flexible solar panels on a commercial level. The solar cells are produced on durable, light weight plastic, the plastic substrate materials result in higher power levels, compactness and flexibility that enable the solar cells to be configured into a wide variety of rolls, foldable packs, or traditional solar panel...

SolarWorld’s 230 watt solar panel

SolarWorld, a solar panel manufacturer that produces solar panels in Camarillo, CA recently launched their 230 watt Sunmodule. The new solar panel represents an evolution in their product line by making significant design changes which include larger solar cells, increased an inch to 6 inches. The solar cell count per solar panel was reduced from 72 to only 60. The reduced number of solar cells increases the current while lowering the voltage which is great for maximizing the number of solar panels that can be wired on a string. The entire solar panel is made right here in the USA except the Junction box which is made in Germany. The SW230 is offered with a silver frame and white backsheet or an ultra low profile black frame with black backsheet. What do you think about SolarWorld solar...
