Produce Aluminum with Solar and Photovoltaic – EUR in SAR
By Sgouris Sgouridis The post below was inspired by my participation at the ARABAL 2017 conference in Muscat, Oman to discuss the options for renewable energy integration in the aluminum industry. It addresses a seeming reluctance I encountered during the discussion to adopt RE with some initial considerations on how the industry can be transformed away from
Neglected pastures thrive under solar panels
by Prachi Patel | Nov 8, 2018 Solar panels could increase productivity on pastures that are not irrigated and even water-stressed, a new study finds. The new study published in PLOS One by researchers at Oregon State College finds that grasses and plants flourish in the shade underneath solar panels because of a significant change in moisture. The results bolster the
Photovoltaic, Wind and Solar Costs Keep Falling Lazard LCOE
Wind and solar have become the cheapest sources of power, and natural gas-fired plants are the best option to back them up, according to Lazard Ltd. The levelized cost of energy(LCOE) from large solar installations has fallen to as low as $36 per megawatt-hour, while wind is as cheap as $29, Lazard said in a report
Utilities See Future Profits in Microgrids: Survey
Utilities see microgrids and related technologies as future revenue opportunities to help counter dampened profits from their traditional services, according to a new study from Accenture. By RGtimeline/Shutterstock.com The finding came from a survey of 150 utility executives across more than 25 countries, part of Accenture’s Digitally Enabled Grid research program, now in its fifth
Wiring solar panels: Calculate in series and parallel wired PV solar panels
Modules connected in series Interconnection of any number of Modules is usually done as a series connection. In this case, the negative terminal of one Module is connected to the positive terminal of the other Module, so that all Modules are supplied with the same current. The resulting total stress is then the sum of
Massive subsidy cuts for photovoltaics decided by the Federal Cabinet of Germany
The Federal Cabinet of Germany has decided the draft energy collection law yesterday. In addition to the special tenders, it also includes the planned reduction of subsidies for PV roof systems between 40 and 750 kWp. The law now goes its parliamentary way through the Bundestag. Last week, the draft bill of the Federal Ministry
Floating solar surpasses 1GW globally – World Bank
By Tom Kenning Global floating solar installations had reached 1.1GW as of September this year, a huge rise from just 10MW at the end of 2014, according to the first report on floating PV from the World Bank and Solar Energy Research Institute of Singapore (SERIS). The report ‘Where Sun Meets Water’ stated that floating solar
Switch Batteries in Parallel Batteries connected in Series online Calculator
Switch batteries or cells in parallel In parallel connection of rechargeable batteries, the positive pole is connected to the positive pole and the negative pole to the negative pole. The charging capacity (Ah) of the individual batteries then adds up while the total voltage corresponds to the voltage of the individual batteries. Basically, only batteries
How to build Photovoltaic 2 go from used Mobile Phone batteries
via Off-Grid.at Do you remember those “inventors” designing their own powerwall systems? One of these “gurus”, Jehu Garcia, went to work after Hurricane Maria to fight the power crisis in Puerto Rico. He posted a video on YouTube introducing his design for a solar generator that costs around $ 550 (about 500 Wh or about
Submerged Photovoltaic Solar Panel (SP2)
The photovoltaic materials, in particular silicon and CdTe, have a negative thermal drift, i.e. they lose efficiency when the temperature increases. Water keeps the temperature of the panel constant thus avoiding the thermal drift, and at the same time the panel doesn’t lose efficiency. This allows us to realize a gain in efficiency of approximately 20%
