With the best technology available, the Sheridan Community School has developed a plan to eliminate their energy costs using and selling self-generated solar power. Schools are among the largest energy consumers in a municipality. In order to create a pleasant learning atmosphere, electricity is needed for classrooms, gymnasiums, and much more. The costs are correspondingly high, but can be significantly reduced when creative solutions using solar technology are applied, as in the example of this forward looking strategy. In Sheridan, Indiana, the Sheridan Community Schools were given particularly attention for their electricity consumption, because the annual cost of electricity has soared to over $ 290,000 and should rise by up to 7 percent in the coming years. But with the installation of 5,900 solar collectors on the school grounds, the electricity bill could be significantly reduced. Also, seven DEGERtrackers D60H with 175 solar modules and an installed capacity of 54.52 kWp generate solar energy every day. With the installation of additional fixed solar systems and rooftop systems, around 960,260 kWh solar energy are produced and fed into the public grid every year. By selling the generated electricity, the school covers the costs of the institutions consumed electricity and is a net-zero energy building. Instead

New figures show that onshore wind is powering ahead in Northern Ireland, generating nearly a quarter of its electricity needs. The latest generation figures released by NI Electricity Networks, show that onshore wind has now passed the 1GW milestone, with 1,029MW of onshore wind connected in Northern Ireland. This year has seen significant delivery of large onshore wind projects, representing £127.4million of local investment since the beginning of 2017. The growth has contributed to official figures published this month showing that in the 12-month period from April 2016 to March 2017, onshore wind generated 22.4% of Northern Ireland’s electricity. All renewable sources contributed 27.1%. In the UK as a whole, onshore wind currently provides 6% of electricity, so proportionately Northern Ireland is way ahead in terms of generation from this power source. Onshore wind is now by far the leading source of clean electricity in Northern Ireland, representing 78% of installed renewable capacity. With world-leading grid management systems, the network is dealing with increasingly high levels of renewables, maximising the growth potential of these technologies. The Chair of NIRIG (Northern Ireland Renewables Industry Group) Rachel Anderson said: “Crossing this 1GW threshold shows just how much of a success story onshore wind is in Northern Ireland.

Easy measurement of photovoltaic panel soiling ratio with an innovative, solid-state solution. Delft, the Netherlands (25 May 2017) – Kipp & Zonen, the world leader in solar radiation measurement, will proudly present a completely new technology and product to monitor PV panel soiling at Intersolar Europe 2017 in Munich. Soiling of the panel glass is one of the major problems in the rapidly expanding solar energy market, with the attendant loss of efficiency and reduction in performance ratios. Now, there’s a new, simple and very cost-effective alternative. Based on Kipp & Zonen’s unique Optical Soiling Measurement (OSM) technology, DustIQ can be easily added to new or existing solar arrays and integrated into plant management systems. The unit is mounted to the frame of a PV panel and does not need sunlight to operate. It continuously measures the transmission loss through glass caused by soiling, so that the reduction in light reaching the solar cells can be calculated. Know exactly when and where to clean DustIQ measures the soiling ratio (SR), which can be translated to power loss in real time. This enables the plant operation and maintenance staff to know when a critical level of soiling is reached and it has become necessary to
