A solar powered water system is one of the easiest solar power systems to install and will ultimately save you time and money.
Unlike on-road electric vehicle programs which can be complicated and depend, in part, upon factors outside a utility's control, non-road programs are less risky and comparatively simple to design, operate, and control.
We think the satellite-image based Virtual Irradiance approach is a scalable and reliable solution to the problem of understanding solar PV performance.
Yes, history has shown that there has been global climate changes that were not brought about by human activities; but-and this is a big but-human activity is accelerating global change and not for the better.
The Sustainable Cities Index from ARCADIS shows that among the top ten cities in the list, most are from Europe, while there are a few cities which are from Asia. Strangely, not a single city from North America makes it to the top-ten list.
A greater use of wood for home heating and steadily growing installation of solar systems are the main contributors to increasing renewable energy consumption in residential buildings and, to a lesser extent, in commercial buildings.
Here is a summary of what Tradeshows, Conferences & Exhibitions to look forward to in the coming months.
The system incorporates panels and micro-inverters and steel and bearings and a microcontroller with an LCD display, to control the daily motion of the array. And, I might add, a light sensor to sense night time and daytime, and an AC current sensor to measure the amps produced (by the array) and amps consumed by the controller.
They can be installed on building roofs or stack at variable heights without a mast and without foundation. They are 100% removable, 100% silent, 100% recyclable and maintenance free.
Similar to the S&P 500 Index, the Solar Stock Index is a market cap weighted composite index.
Wind Energy Timeline - From Persian Windmills Crushing Grains to Vesta's Wind Turbines Churning out 8 MW of Output
The global wind power market continues to rapidly expand in 2015. It is expected that global wind energy production will surpass 65 gigawatts by 2020!
Contractors can access high-resolution aerial imagery of properties - top-down and north, south, east and west views.
The East Coast of the U.S. experienced up to 5% lower than average levels of solar irradiance in 2014, negatively impacting overall performance of solar sites in the region. Concurrently, the West Coast enjoyed irradiance levels up to 10% higher than average, widening the productivity gap between projects in the country's two areas of highest solar development. This disparity is clearly seen in the 2014 Solar Performance Maps of the United States, released today by Vaisala, a global leader in environmental and industrial measurement. While it is well-established that the solar resource of the East does not match that of the West, the Atlantic Coast has a large volume of operational capacity and it is therefore of critical importance for project operators in the region to understand the reasons behind below average energy output and whether it is due to malfunctioning equipment or weather variability. Vaisala's 2014 study illustrates the impact of short-term, month-to-month weather variations on performance at U.S. solar projects and places them into a long-term context. This reveals frequent and significant deviations from long-term average irradiance conditions and highlights the clear requirement to analyze the effect of solar resource variability on both over and underperformance. From an annual perspective, this year's weather patterns had an adverse effect on a large number of installations along the Atlantic Coast from Florida to Massachusetts, as well as Texas, while the bulk of projects in California and the Southwest saw an uptick in solar irradiance that may have increased overall 2014 production at many sites. However, these annual variations only offer a high-level view of project performance. Vaisala also conducted a monthly analysis that gives a much more robust understanding of how specific weather conditions affected solar production throughout the year.
Catherine Shu for TechCrunch: Solar panels are becoming increasingly affordable, but many people still face barriers to harnessing the power of the sun for their own homes. For example, they might live in an apartment or in a house where the roof is angled or structured improperly for solar panel installation. A new Boston-based startup called CloudSolar is offering an intriguing solution. Founded by a team including two electrical engineering Ph.D. candidates and currently raising funds on Indiegogo, CloudSolar lets people buy a solar panel, or a share in one, on a farm that is expected to be completed by 2016 (erecting the solar panels will only take a couple of months, but the company also has to deal with utility and land permits, which will take longer). Once the farm is up and operating, electricity generated by the solar panels will be sold to local utilities. Solar panel owners are promised 80 percent of the total proceeds created by the panels over the next 25 years, and help with applying for whatever tax credits they are eligible for. They can monitor how much energy their panel is producing, and how much carbon dioxide emissions it is estimated to offset, through an app.
Eric Wesoff for GreenTech Media: Energy storage is a small market experiencing fierce growth. The U.S. installed 61.9 megawatts of energy storage in 2014, and GTM Research is forecasting 220 megawatts to be installed in 2015. But, as with the U.S. solar industry, energy storage projects are clustered in states with incentives or in regions where markets are able to place a value on storage. So it's no surprise that California, Hawaii, and New York have assumed early leadership in energy storage by virtue of their unique incentives, mandates and markets, according to the inaugural GTM Research and Energy Storage Association U.S. Energy Storage Monitor report.

Our batteries have Xtreme thick plates with (XC Diamond Plate Technology) added to them. They have been designed for hours of heavy discharge each day, followed by a fast recharge during the daylight hours. Very few batteries can take the grueling deep discharge-recharge cycle every day for long periods of time. U.S. Battery has proven time and time again that our solar battery line can stand up to this type of battery torture day in and day out for years to come. When you demand reliable energy storage count on U.S. Battery every time!
