Even before the new cuts were announced, Athens had been targeted for legal action by the Hellenic Association of Photovoltaic Energy Producers (SPEF).
Both governments are facing action from sector investors and trade groups, with Athens under attack from the Hellenic Association of Photovoltaic Energy Producers (SPEF).
The hundreds of photovoltaic chips gathering energy at the center will be cooled by the same sort of microchannel water cooling that kept Aquasar from frying, letting each chip safely concentrate 2, 000 times the solar energy it would normally face.
It comes as utilities have been turning to increasingly cost-competitive photovoltaic farms to meet their renewable energy mandates.

Conventional photovoltaic cells, made of silicon, are designed to collect energy from sunlight.
The UCLA Engineering team created a new type of energy-harvesting polarizer for LCDs called a polarizing organic photovoltaic, which can potentially boost the function of an LCD by working simultaneously as a polarizer, a photovoltaic device and an ambient light or sunlight photovoltaic panel.

SMUD's solar energy program is particularly popular, with solar panels equipped with photovoltaic cells turning hundreds of area homes and businesses into mini-power plants.
Tellingly, about two-thirds of bids for solar energy contracts last year (by electricity generated) were for photovoltaic projects and only a third were for solar thermal power plants, which deploy vast arrays of mirrors to heat liquids and produce steam to drive an electricity-generating turbine.
FORBES: California Reveals Price It Pays For Renewable Energy
Back on July 27th, I wrote about how surprised I was to find shares of Power-One (PWER), a provider of renewable energy and energy-efficient power conversion and power management solutions such as photovoltaic inverters used in solar power applications, trade down after reporting blow-out second quarter results.
Even with the ability to convert sunlight into electricity with high efficiency using photovoltaic solar cells, many challenges prevent us from being able to power all our energy needs with solar panels.
Distributed generation ( DG) generally refers to renewable energy systems of less than 20 megawatts (MW), often rooftop solar photovoltaic (PV) arrays, installed close to load and existing transmission.

Both companies manufacture components for photovoltaic panels and statements from their executives were issued and triumphed by the Coalition for Affordable Solar Energy, an alliance of solar installers and other companies opposed to SolarWorld Industries America, the U.S. subsidiary of a German photovoltaic manufacturer, to secure tariffs against Chinese competitors.
And NRG has invested in large-scale photovoltaic farms in California and Arizona, both of which have also obtained U.S. Department Energy loan guarantees.

Meanwhile, wind and building-integrated solar modules with high efficiency photovoltaic materials can supplement our electrical generation capability, as stricter building codes and improved insulation can decrease the energy used to heat and cool buildings.
FORBES: Solar-Powered Cars? Clean Energy Hype Needs a Sober Dose Of Reality
In 2007, Chevron-Texaco's venture capital arm bought significant stakes in two solar energy companies: BrightSource Energy, a developer of utility-scale solar plants, and Konarka Technologies, a developer of photovoltaic materials.
NextEra Energy Chief Executive Lewis Hay told me last week over breakfast that he had higher hopes for solar photovoltaic (PV) power than for solar thermal power because the prices of solar PV panels were falling so extraordinarily fast.
FORBES: Solar Thermal Hopefuls Make Their Case, Battle For Financing
The UCLA engineers have created a novel concept for harvesting and recycling energy for electronic devices - one that involves equipping these devices' LCD screens with built-in photovoltaic polarizers, allowing them to convert ambient light, sunlight and their own backlight into electricity.
