Researchers behind a techno-economic analysis of energy communities in Italy and Portugal say that collective self-consumption is a more lucrative solution than individual installations. March 12, 2024 Pilar Sánchez Molina An international research group has carried out a techno-economic evaluation of energy communities in Italy and Portugal under their respective regimes for self-consumption. The researchers also looked at the impact of post-pandemic policies and identified the optimal PV system designs for four different community configurations in the two countries, based on financial incentives. Italy has also been granting two different…

In 2021, Montana ranked in the top 10 for states with the largest share of electricity from renewable sources. Montana also receives an average of 4.93 peak sun hours — the daily recommendation for solar panels is 4 hours of direct sunlight, making Montana a great location to install them. Installing solar panels means you’ll be less dependent on the traditional energy grid, which is especially helpful during power outages and can lead to lower energy bills. Significant decreases in solar prices and increases in solar incentives make now the…

The Salzgitter Group has partnered with Energiesysteme Groß GmbH & Co. KG and Agrarbetrieb Gut Merbitz GbR on their photovoltaic (PV) project in Wettin-Löbejün, Germany. Salzgitter Flachstahl GmbH and IG Merbitz Solar GmbH, the project company for the PV power plant in Merbitz, have now concluded a green electricity supply agreement (PPA). The electricity will be generated by a ground-mounted photovoltaic system currently under construction at the Merbitz site in Saxony-Anhalt. “The electricity supply agreement now concluded between our two companies underlines the importance of renewable energies for the energy…

Okinawa Institute of Science and Technology Graduate University The shift toward renewable energy sources decreases our reliance on fossil fuels, providing a cleaner, more sustainable alternative. However, with their increasing use and development, we also face new challenges. Solar photovoltaic (PV) plants, for instance, are subject to the whims of the weather and many other environmental conditions. This variability leads to inconsistent power output from these plants. Prof. Mahesh Bandi, head of the Nonlinear and Non-equilibrium Physics Unit at the Okinawa Institute of Science and Technology (OIST) and Prof. Golan…

Currently, there is no net metering program available to Hawaii residents. The state discontinued its net energy metering program in 2015. Previously, all utility companies offered net metering to solar panel owners, including Hawaiian Electric (HECO).

Minnesota is known more for lakes than it is for the sun. But with falling solar panel costs, accessibility of solar power in the North Star State is growing.   The price of solar panels has dropped by 52% in the last decade, according to the Solar Energy Industries Association. Solar incentives, rebates and tax credits can bring the cost of solar panels down further.  There are a couple solid state-level incentives in Minnesota. Net metering policies allow you to gain credits from sending the excess energy generated by your solar panel system back to the grid. These…

In the 80 years since the shocking collapse of the Tacoma Narrows Bridge in Washington, engineers have designed suspended structures to minimize their universal weakness: resonance. If not designed to deal with oscillations caused by forces like wind, the frequency of these forces would cause tensions to build and inevitably break the structure. When Jim Clair examined how to focus mirrors at a concentrated solar energy power plant, he thought about suspending the mirrors on cables but remembered the images of the Tacoma Narrows Bridge shaking itself apart. To determine…

To determine the best solar company ranking, the Forbes Home editorial team analyzed 26 major companies, with each company’s star rating determined by evaluating a variety of metrics, including: Years in Business, Services and Financing (22%) How long a company has been in business, the services it provides and the financing options available are important factors in determining the best solar panel installation companies. These factors make up a total of 22% of the metrics. Equipment Options (4%) The type of equipment available from each company makes up 4% of…
