Car parks with space for 80 cars or more in France are now required by law to be covered with solar panels.

  • Parks between 80-400 spaces have 5 years to comply
  • Parks with spaces of 400+ have 3 years to comply

This will result in about 11 gigawatts of power.
Imagine if places like US would embrace this and help keep cars cool while generating electricity. Or adding solar panels on top of all the ridiculously giant shopping malls, would create enough electricity to cut their power consumption by a huge percentage.

#Iran plans to install 25MWs worth of solar panels in the #Sistan & #Baloochestan (south east of the country bordering #Pakistan and #Afghanistan) province by the end of the year

This is what I have been dreaming about. The region receives close to 300 days of sunshine and us one of the poorest province in the country.

These #SolarPanels will help boosting the local economy. create new jobs and help with energy security in the region. 25MWs is not much, but it is a good start/

How to clean solar panels without water – A new electrostatic based solution

Solar power is expected to reach 10 percent of global power generation by the year 2030, and much of that is likely to be located in desert areas, where sunlight is abundant. But the accumulation of dust on solar panels or mirrors is already a significant issue — it can reduce the output of photovoltaic panels by as much as 30 percent in just one month — so regular cleaning is essential for such installations.

Attempts at waterless cleaning are labor-intensive and tend to cause irreversible scratching of the surfaces, which also reduces efficiency. Now, a team of researchers at MIT has devised a way of automatically cleaning solar panels, or the mirrors of solar thermal plants, in a waterless, no-contact system that could significantly reduce the dust problem, they say.

Other groups have tried to develop electrostatic based solutions, but these have relied on a layer called an electrodynamic screen, using interdigitated electrodes. These screens can have defects that allow moisture in and cause them to fail, Varanasi says. While they might be useful on a place like Mars, he says, where moisture is not an issue, even in desert environments on Earth this can be a serious problem.

The new system they developed only requires an electrode, which can be a simple metal bar, to pass over the panel, producing an electric field that imparts a charge to the dust particles as it goes. An opposite charge applied to a transparent conductive layer just a few nanometers thick deposited on the glass covering of the solar panel then repels the particles, and by calculating the right voltage to apply, the researchers were able to find a voltage range sufficient to overcome the pull of gravity and adhesion forces, and cause the dust to lift away.
