In a webinar today, the Maryland-based startup announced that their revolutionary power generating windows, which they say can generate 50 times more power than conventional solar panels per building, would soon hit the market. Unlike traditional and opaque PV technology, SolarWindow can be readily applied as a coating to any glass window or … Read more
When polling firm Gallup asked people what forms of energy they wanted the U.S. to emphasize, solar came out on top, with 79% saying "please give us more of that sweet, sweet sun energy" — or something to that effect. "The hills are alive with the sound of solar panels." Photo by Boris … Read more
The home owner will save more money in the long run, depending on the amount of hot water required, system’s performance, geographic location, and cost of conventional backup. The following are the key things to consider when selecting a solar water heater; 1. Average Daily Efficiency and Average Heat Loss Coefficient These … Read more

Solar cells were once a custom product reserved for satellites and military use. In 1977, a solar watt cost $ 77. The cost is now about 80 cents, and solar energy begins to compete with conventionally generated electricity more expensive. If the price will fall further, solar energy could develop into an overwhelming, hope … Read more
India and the U.S. National Space Society have just recently presented their own version of a space solar power initiative. Basically, the plan is to introduce their idea to government leaders around the world, hopefully prompting a positive response, followed most likely with the initiation of a project that would lead to the actual … Read more
Solar photovoltaic installations has been one of the fastest growing energy sources in the US over the past six years, with a compound annual growth rate of over 50% since 2007, according to NPD SolarBuzz, a market analysis firm. Solar PV installations are forecast to increase an additional 80% over the next … Read more
The very first Solarcopter prototype was designed to fly solely from energy generated from a photovoltaic panel, but with the assistance of a reserve battery that was also charged by the copter’s solar panel. The purpose of this battery was to provide energy when the solar panel was not able to … Read more
1. The first was Da Vinci. Solar energy is not a “breakthrough” of the XXI century but it was used since the fifteenth century. Leonardo Da Vinci conceptualized the idea of solar energy at that time when, using a concave mirror, he was directing the sun's energy to heat water. 2. More … Read more
The world's largest solar boat is a catamaran named Tûranor (the name comes from Tolkien's Lord of the Rings, it means Master of the Sun) operated by the PlanetSolar Expedition. They've been roaming the oceans for a couple of years, completing a record-breaking 18-month, 37,000-mile trip around the world last year. This year, the … Read more
This squaraine dye boosts light absorption and recycles electrons, improving the conversion of light into energy. The results suggest a new route for the development of lower-cost, higher-efficiency photovoltaics, the scientists said. Scientists at Yale have improved the ability of a promising type of solar cell to absorb light and convert it into … Read more
But which comes first, using solar power or buying an electric car? Remember that environmental concerns are just one of several reasons to buy an electric car. Thus far, we’ve not seen any surveys that address which comes first, the plug-in car or the solar panels (hint, hint). But we do … Read more
Prior to the UK government’s consultation on solar support, all solar PV was eligible for 2 Renewables Obligation Certificates (ROCs) per MWh. This has now been reduced to levels as low as 1.6 ROCs/MWh. However, the cuts are not quite as severe as previously feared – officials had previously threatened to cut PV rates … Read more
The package includes two programmes to help stimulate private sector investment to provide low carbon energy in Africa, a £15 million programme to reduce emissions from cattle ranching and support smallholder farmers in Colombia and a £1.5 million programme to help developing countries to develop strategies to reduce their emissions. The Green Africa … Read more
Microinverters all but disappeared from the market in the early 2000s, due to their high cost and relatively low efficiency. But over the last five years, rapid advances in semiconductor technology and improvements in efficiency and reliability have made microinverters a viable alternative to central inverters. Today, ACPV systems account for more than 30% … Read more
Plunging costs throughout the solar PV technology chain have helped to improve the cost profile of solar PV plants. But upstream upheaval also contributes to questions about supplier quality and viability, and adds uncertainty and risk for potential investors in a PV project. Standard certification of individual components by themselves is no longer sufficient … Read more
A very hot area in solar R&D is screening-engineered field-effect photovoltaics (SFPV) – it has the potential to enable low-cost, high-efficiency solar cells to be made from virtually any semiconductor material, according to researchers from the US DOE's Berkeley Lab and the University of California (UC) Berkeley. While still in its infancy, SFPV … Read more
