Sundown at Intersolar US

Today was the last day of Intersolar US in San Francisco. A very successful show here in the USA, there was a high demand for renewable energy in the US and the conference proved it by attracting over 12,000 visitors and 2oo exhibitors. Intersolar has been going on in Europe for many years, this was the first year the conference organizers brought the show to the US, and I have a strong feeling that they’ll be back in the USA next year. Let’s dive into some interesting products we saw to conclude the coverage of Intersolar US. Solar Panels are getting larger and producing more output, the picture above shows a 250watt solar panel! That is one monster solar panel. It seems like in the near future with increases in output and solar panel size consumers could be using less solar panels in certain installations. Thin film solar glass is an interesting yet expensive concept not ready for the residential market although its interesting to see the development of windows that can produce electricity. As this technology evolves consumers should expect to see more efficient better looking solar power windows that we’ll even see at the residential level. We’re seeing more combination solar panels being presented at solar power conferences, the last one we saw were at Solar 2008 in San Diego made by an American company. The Combination Panel (made by a German company) shown below heat water and produce electricity using the same panel. Traditionally, solar electric and solar hot water were two different systems…this product is unique because it turns two different systems and combines them into one panel that could save customers surface area and money, while reducing both electric bills and natural gas bills for water heating. Killing two birds with one stone. Even though Intersolar was geared more toward the utility scale projects, we still had a chance to interact with other solar power professionals and meet interesting people from all over the world who are working on interesting products that help the industry move forward in the residential and small business...

Day two at Intersolar.

Continuing the coverage of new products at Intersolar in San Francisco this week, our team has made some interesting observations. Lumeta a company that focuses on BIPV (Building Integrated Photovoltaics) showed off two interesting products, one which we covered yesterday was solar panels that mount flat onto roofs with adhesives; we got some close-up shots of these easy to install solar panels. The flat thin solar panels are made for large flat commercial building rooftops. Lumeta has not forgotten the residential folks; aesthetics is often a concern for residential solar panel shoppers which can be mitigated with solar panels that are integrated into roofing shingles. Lumeta showcased a unique solar shingle product line at the expo which caught our eye. Power Outages / Blackouts are something every solar power shopper wants to avoid when buying a grid-tied solar power system, although in reality grid tied systems go down when there is a power outage. Inverters automatically shut down when there is a blackout because there is no where to send the power generated. Adding battery backup to your grid-tied system is an expensive option because of the upfront cost and ongoing maintenance of the batteries. This typically discourages grid tied solar power shoppers to add a backup battery system. TerraWatt Power is working on a new inverter, that does not need batteries to keep your home up and running during a blackout during the day. Instead of the inverter, “going to sleep” or shutting down during a blackout, TerraWatt Power’s grid-tie inverter stops feeding the grid and directly powers your home! So you would survive a blackout during the day and no need for batteries! TerraWatt Power’s grid-tie inverter is a great example of how solar / clean energy equipment is...

Day one at Intersolar

The GoGreenSolar.com team is at Intersolar, a major solar energy trade show taking place in San Francisco this week. One of our missions at the trade show is to provide you a sneak peak into new products that are going to change the solar energy market. First, I’d like to talk about the concentrated solar power technology that we saw. Concentrated PV is typically applied to large scale projects, although there are some companies releasing small scale concentrated products. The picture above shows a Sopogy concentrated parabolic through, these units are similar to ones being used in Nevada solar one, although they are called MicroCSP meaning the troughs are scaled down version. Each MircoCSP unit can produce 500watts depending on the size. The solar panel above uses mirrors to concetrate the light to produce a greater output and lower the cost of the installed cost. This Solar Concentrated Panel was developed by a new company in the game called SolFocus. Their product line is geared to utility scale projects. A large thin film solar panel that can be used for industrial and utility scale projects. Below are some other interesting shapshots of products we found interesting: A standard racking system you would find on a typical residential installation. Solar Panels that stick flat onto a roof, these panels have adhesives that mount the solar panel to the roof...

Upcoming trade shows focusing on Solar Power

There are a couple solar power conferences / expos that I want to let you know about because it would be a learning experience if you are looking to get more involved in the industry or are considering to purchase a solar power system, plus the GoGreenSolar.com team will be at the following trade shows, so we hope you can make it out. Intersolar North America in collaboration Semicon West 2008 will be held at the Moscone Center in San Francisco, CA July 15-17th, this conference will attract over 10,000 attendees as well as 1,400 exhibitors. Solar Power Conference 2008 , the premier conference and trade show for the solar power industry this year is going to be held in sunny San Diego, CA later this year October 13-16th. I’ve been going to these conferences over the last few years and they only have I seen an explosion of companies inking up business deals but I have met with many interested consumers who are looking to go solar on their home or small business. So if you’re ready to roll up your sleeves and get your hands dirty with solar power, go ahead and register….give us a call and let us know if you’re going to be at either ones of the conferences because we’d love to buy you...
