Solar Choice provides a solar PV price index for Australian solar that is updated monthly.

A glut of photovoltaic solar panels has swamped the market due to increased production but less demand, causing some companies to go bankrupt and a general malaise for the whole industry.

Researchers have discovered that an exotic form of silicon may improve solar cell efficiency.

In the latest issue of Science, researchers from Lund University in Sweden have shown how nanowires could pave the way for more efficient and cheaper solar cells.

In a breakthrough that could lead to more efficient and cheaper solar cells, scientists at Sweden's Lund University claim to have identified the ideal diameter for nanowires to convert sunlight into electricity.

Scientists based at Empa, the Swiss Federal Laboratories for Materials Science and Technology, have set a new efficiency record for thin-film copper indium gallium (di)selenid (or CIGS) based solar cells on flexible polymer foils, reaching an efficiency of 20.4 percent

Prices for solar modules -- the part of solar panels that produce electricity -- will continue to fall, in line with the long-term trend since 1980, according to a survey of experts by Near Zero, a nonprofit energy research organization.

Renewable energy solutions like wind and solar operate on nature's timetable. When the sun blazes or when the breeze blows, power is plentiful -- but not necessarily at the moments when consumers need it, like on a hot, calm summer night.

The sun ejects a continuous flow of electrically charged particles and magnetic fields in the form of the solar wind -- and this wind is hotter than it should be. A new study of data obtained by European Space Agency's Cluster spacecraft may help explain the mystery.

Solar Sunflower, một sản phẩm sáng tạo từ XD Design có thể sẽ hấp thụ và chuyển hoá thành điện năng để cung cấp cho các thiết bị điện tử như máy nghe nhạc, smartphone…

California just recently passed the milestone of 1 GW of solar power production (in August). And now it has just surpassed another milestone — it nearly reached that peak August generation level during the week of the Winter Solstice, which is the least-sunny time of the year, setting a new winter solar power generation record.

Surviving without electrical power isn’t something we’re very good at any more. Here in the U.S., if you don’t electricity at home, it’s usually because it’s been temporarily knocked out by a storm or your roommate forgot to pay the bill again.

Renewable energy could fully power a large electric grid 99.9 percent of the time by 2030 at costs comparable to today's electricity expenses, according to new research by the University of Delaware and Delaware Technical Community College.

Princeton researchers have found a simple and economical way to nearly triple the efficiency of organic solar cells, the cheap and flexible plastic devices that many scientists believe could be the future of solar power.

An insight into the properties of fullerene is set to open the door to a new class of electronic acceptors which can be used to build better and cheaper organic solar cells.

The Australian Government announced last week that CSIRO would be leading a new solar research initiative worth over $87 million AUD, an initiative which aims to lower the cost of solar thermal power from 25 cents a kilowatt hour down to 10 cents/kWh.

The British Department of Energy and Climate Change (DECC) has released a five-year plan for the solar and biomass industries in an attempt to give investors certainty on subsidy levels for the 2013–2017 period.

“This increase in module efficiency, coupled with our thin-film technology’s real-world yield advantage when compared to crystalline silicon PV, results in higher energy density and lower levelized cost of energy (LCOE).”

Although critics of renewable energy may claim that it isn't reliable enough to power a grid, a new study gives proponents of clean power – such as wind and solar – fresh ammunition to respond. A thorough analysis carried out by the University of Delaware and Delaware Technical Community College concluded that renewable energy could reliably power a large electrical grid 99.9 per cent of the time by 2030, at a cost that matches today’s electricity prices.
