Fri, 17 Jun 2011 07:25:07 GMT http://www.solarpowertalk.com/index.php?name=Forums&file=viewtopic&p=77#77 Hi my name is Tony of cssolar in spain, I import and sell vacuum tube solar water heaters, the type of unit I use are pre heat indirect compact units made by Deno Solar Equipment which has been producing and exporting all over the world for over 10 years. I have found these units are well suited to the hot Spanish climate and will produce most of the yearly hot water for a domestic house. Pre heat units have a vented main tank which will allow water to boil out of the system in the event of over heating, water is topped up a small assistant tank and the water is heated by a copper coil heat exchanger to provide mains pressure hot water. Sun, 08 May 2011 19:16:33 GMT http://www.solarpowertalk.com/index.php?name=Forums&file=viewtopic&p=76#76 I have a new system in KEFALONIA Greece of 2.8 kw consisting of 4 solar panels and two wind turbines, xw 4024 inverter two charge controllers and 8 230 amp / h Trojan 6 v batteries. Can some supply the best settings for the inverter, the system is not grid tied and I wan to use the system to control the power to the house when I am not there. Also at a later date add more solar panels and a dc pool pump for running my swimming pool Any help appreciated Thu, 05 May 2011 19:47:07 GMT http://www.solarpowertalk.com/index.php?name=Forums&file=viewtopic&p=75#75 solarenergyeasy wrote: Hi Curasun, the cheapest solution that I can suggest is to use black hosing. You would create a spiral shape with the hose placed on your roof where it gets more light. The longer the hose, the more time the water has to heat up before exiting. Hope this helps, cheers Thank you solarenergyeasy we'll give it a try ... looking forward to a warm shower!

Gathering a group of interested buyers, can combine the cost so that each buyer gets a great deal. But, this is easier said than in practice. I've been inquiring for solar panels from China and they were the prices offered to me. Some were even as low as $1.50 per watt! before buying however; it's best to get a sample and if the quality is good, then you may want to proceed gathering the group that's interested and share the overall costs. That way every one can get cheap solar power.

Both countries will do many new things, but most likely each will follow different courses... Both countries are likely to more eagerly court the oil producing countries, whether or not they like it. Both countries are likely to place higher emphasis on renewable energy. Beyond these two major approaches however, the specifics for each country could be quite different (here's a presentation that provides India's perspective on this). One can expect India to be a bit more sensitive to world opinion in this regard than China, and I guess that should not really surprise anyone. What are your thoughts on how India and China's approaches to ensure their nations' energy security? Fri, 03 Dec 2010 10:08:05 GMT http://www.solarpowertalk.com/index.php?name=Forums&file=viewtopic&p=71#71 A couple of centuries back, folks ate food that was grown quite close to where they lived. It seemed natural. But as time went by, they started yearning for food that was grown in other places but not theirs. They were able to get these, thanks to the progress in transportation technologies. Today, it has come to such a stage that most of what we consume (and it not just about food) are imported from regions far away from where we live. To some extent, I guess you can justify consuming products that are not local. For instance, not every food that is healthy could be grown in any specific region alone. In addition, sometimes it makes sense for your region to grow what grows best there are barter these with products from other regions where they grow best. In many other cases, I opine that locavorism makes tremendous sense, both to your health and pocket and to nature's! And let's not think locavorism is a fad, and I am not advocating locavorism because it brings down the cost of transportation and hence, the carbon footprint from a particular food product. As this post's author advocate locavorism, I also think locavorism is more about building a sustainable and prosperous community around you than just reducing the total energy costs of food items. Wed, 01 Dec 2010 09:45:07 GMT http://www.solarpowertalk.com/index.php?name=Forums&file=viewtopic&p=69#69 Amid the excitement that is brewing in the air over solar, wind and biomass based power, some of the lesser known renewable energy sources hardly find a mention or discussion. One of these is the OTEC (or ocean thermal energy conversion). I could not find too many discussions online for OTEC, except perhaps for posts such as these that explored the potential for OTEC in India. "While I am sure there are estimates for the potential worldwide for OTEC, I would rather disregard it at the moment because this is a very nascent concept and most such estimates would prove to be close to guessworks! I’d take estimates for India with the same pinch of salt – however, if you are looking for estimates of potential, I understand MNES has estimate that India has a potential of exploiting between 80,000 – 180,000 MW of OTEC based power. Even if it is 80 GW, it’s not a bad amount, assuming these folks indeed have done a good estimate. We have about 160 GW of installed electricity capacity, so that’s 50% of what we have today. I’ll tell you why I find the OTEC thing quite interesting, even though it is going to be quite a while before we get the first unit of electricity from it. There are concurrent, non-power benefits from OTEC. These are the ones that Wikipedia lists: Air-conditioning, chilled-soil agriculture, aquaculture, desalination, hydrogen production and mineral extraction" (Source: EAI Blog) I think the author has a point. OTEC is not just about electricity production, it has beneficial effects beyond power production alone. I think more R&D should be undertaken in this area. What do you think?

Could you please share your opinion about using a huge 3 phase inverter or small single phase ones?Pros and cons? Thanks Wed, 01 Sep 2010 14:14:23 GMT
