Earlier this month, Governor Schwarzenegger signed legislation to buy solar power from relatively small private generators for rates above market value. Hawaii is next in line with this European-style tariff — the Hawaii Public Utilities Commission and Governor Lingle just recently set a similar initiative for Hawaii.
Hawaii’s initiative will make it possible for homeowners and businesses to sell power they generate from small to medium-scale renewable energy projects (i.e. solar panels) to Hawaii’s main power producers at higher than market-value rates.

The National Renewable Energy Laboratory has released The Open PV Mapping Project showing the progress of solar installations on private roofs from 2000 to (currently) now, beginning with a flurry of activity in California, then moving to Wyoming, of all places, and WIsconsin. Gradually the states turn yellow and then orange over time as they add more solar power.
Dell has been a trend-setter when it comes to the incorporation of greener technologies to reduce their corporate carbon footprint and they’re doing it again! Although this time they are following the lead of Google, by installing solar trees in the parking lot of their head office in Round Rock, Texas.

San Diego Gas & Electric has embarked on a demonstration project to test the commercial viability of a new concentrated solar power system that uses shallow pools of water as a passive cooling system for high-efficiency solar cells. The unique proprietary technology was developed by Pyron Solar of Sorrento Valley, California.
The new technology could be attractive in land-rich areas, and it may also have some application for introducing sustainable energy to more densely developed areas, since its use of high efficiency solar cells enables it to pack more generating capacity into less space. It also may prompt some new exploration of the opportunity to double up solar energy generation with other operations, such as fish farming.

A contract has just been signed to deliver 600 gigawatthours a year of solar power between the US division of Spain’s giant
Abengoa, and PG&E in California. Abengoa Solar hopes to succeed where BrightSource recently failed to overcome local NIMBY issues and Senator Feinstein, in its plan to site a 250 MW solar thermal plant in the made-for-solar Mojave Desert.

The South African government and the Clinton Climate Initiative (CCI) have signed an Memorandum Of Understanding to develop a plan, before year end, to establishment a Solar Park in the Northern Cape.
If the black areas above were covered with PV panels, it would provide all the world’s energy needs.
The Clinton Climate Initiative (CCI) is convinced that the contribution of solar energy to the world’s energy needs is about to boom. It is already developing projects in India, Australia and in the South Western States of the US. Now it is co-operating with the Department of Minerals and Energy (DME) to develop a Solar Park in the Northern Cape that would speed up South Africa’s uptake of renewable energy.

Sharp Corporation has just announced that it has achieved the world’s highest solar cell conversion efficiency using a compound layered design based on the technology used in the solar cells that power space satellites. Mindful of the link between sustainable energy and the future market for consumer electronics, Sharp has been aggressively pursuing solar efficiency improvements that lend themselves to commercial application.
Instead of silicon, compound solar cells use two or more photo-absorption layers composed of different elements. The trick is to find materials that generate the most current with the least waste. Sharp’s innovation is a proprietary technology that enables it to produce a high-efficiency crystalline compound, InGaAs (indium-gallium-arsenide), which boosted the efficiency of Sharp’s previous cells from 31.5% to 35.8%.

Solar water disinfection is an idea so simple, it hurts. Now a Georgia Tech scientist may be on to a new high-tech twist that could make this no-cost, zero emission ultraviolet (UV) water disinfection method even more quick and effective.
Solar disinfection is a proven method of killing germs in drinking water by exposing it to direct sunlight in a clear plastic or glass bottle. Dr. Jaehong Kim of the Georgia Institute of Technology has just been awarded a $100,000 innovation grant by the Water Environment Research Foundation for his work in developing a new coating that could be applied to bottles to shorten the solar disinfection process and improve its effectiveness. Though not (yet) practical for large volumes of water, solar disinfection has proven to be a sustainable answer for people in remote locations or impoverished areas that lack the resources to disinfect their drinking water through other means.

Solarmer Energy broke the world record for plastic cell efficiency last year. Now, they’ve just broken it again.
The new efficiency record is 7.6% and it breaks 7% for the first time.

Just the other day, I wrote that it was a great time to go solar, especially due to the great rebates and discounts on solar technology. Apparently, I jumped the gun and was a few days early. A new report by Lawrence Berkeley National Lab — “Tracking the Sun II: The Installed Cost of Photovoltaics in the US from 1998-2008” — shows a significant decrease in solar costs over the last ten years and shows that now is a great time to go solar.

This week The Bogman heads to Phoenix to offer 1 Block off the Grid solar discounts for neighbors who go solar together. And what better city to go to! Phoenix was super hard-hit by the housing crisis. It has had 54% drops in property values, some of the worst in the nation.
So this may not seem like just the perfect time for Phoenix (including including Glendale, Scottsdale, Tempe, Mesa) to go solar. But, there’s one thing that Phoenix residents should know: Solar raises property values!
