Yes, I have a physics degree and I’ve studied PV and I use the NASA stats. Watts is what we’re talking about – It’s always direct, otherwise it wouldn’t make sense. Direct sun generally accepted to be very close to 1 kW per square metre at the earth’s surface. 1 kW per square metre directly on the glass produces 30W per square metre. Which would be 3% efficiency, which is about what you would expect for such technology, where the light is very indirect. If you have a huge area of glass (like a high rise office) and a good price, it could be worth doing, considering the other benefits as well.

Stan, I agree with protecting windows from the sun too, but what if they can make a film to retro fit on the inside of a window? Seeing the infra red and UV can be blocked to a high extent, when the need comes to exclude more light the internal blinds can be drawn and reduce a/c needs further.

I can imagine, in the future, different grades of this glass with higher efficiency/ less light transmittance for different latitudes. Also I can imagine a sunshade version, or even glass solar cell louvres external to the highrise window that track the sun for greater efficiency.

The GOI has provided various tax and fiscal incentives to electricity generated from specific energy sources such as accelerated depreciation, etc. There are incentives available to renewable power projects at state level as well. Many of these states have specific policies for the source of energy (such as separate policies on wind and solar), which have high potential in a particular state. Through these policies, the state governments grant various fiscal incentives such as exemption of electricity duty, exemption from cross-subsidy surcharge, exemption from payment of stamp duties and land registration charges and exemption from transmission and distribution charges for wheeling of power. Certain states also provide procedural relaxations such as deemed non-agricultural status of the approved project land. In certain states, open access is given on priority basis or deemed to be given if the application for open access for renewable power projects is not granted within the time frame specified under the regulations. However, in view of the increased generation from renewable sources and the enhancement of technology, there seems to be a reversal in the trend, as it is now being argued that renewable projects can have parity with conventional sources of energy. For instance, in Tamil Nadu and Karnataka, transmission charges, cross-subsidy charges and other charges have been made applicable for new solar and wind energy projects.

Using Google’s TensorFlow machine-learning system, able to process a massive amount of images for near real-time recognition, two Cupertino students working with Google’s AI Impact Challenge have deployed a working prototype to identify, predict and send early warnings of forest areas at risk for wildfires. To do this, the system processes a massive amount of images and weather data to determine the moisture content of dead forestation (dead branches and leaves) – fuel for a destructive wildfire.

In cooperation with the Department of Energy, these floodlights will be retrofitted on six high masts in the Katlehong region, in Ekurhuleni.

Company profiling of all top players involved in the Solar Street Lights market. Profiling of any another specific player can also be provided.

Michael A. Perry Memorial Park statues — The oversized bunny on a bat and a turtle with a mitt and baseball at the corner of East Golf Links Road and South Pantano Parkway look like playful public art — and they are — but they’re meant to be a more visible marker for the park, which is tucked back off those roads and named for a 12-year-old boy who was murdered in 1984.

Amazon offers a three-pack of Philips A19 LED Dusk-to-Dawn Light Bulbs for $15.10 Prime shipped. For comparison, it usually sells for around $25 and today’s deal is a new Amazon all-time low. Home Depot charges around $7 for a single bulb. Aside from the obvious benefits of LED lighting, these bulbs have a built-in sensor that help cutdown on unnecessary usage. Each unit is rated for 22,000 hours of use. Rated 4.5/5 stars.

The newest commissioner, Jason Shaw, who was appointed after Doug Everett resigned before the end of his term in November, said he’s keeping an open mind on solar.

But the benefits are pretty obvious if marijuana growers are in it for the long haul. Aside from sizable up-front expenses, solar panels significantly reduce electricity costs in sunny growing regions of the country, and they’re environmentally friendly, thereby reducing greenhouse gas emissions.
