PV-installations Sample Clauses

PV-installations. Photovoltaic means the direct transformation of sunlight into electric current. In general, two types of PV-systems can be identified: there are systems with mains connection and isolated operated systems and these are the type of PV-systems standing-alone, which means that they have no connection to the public power supply system and therefore need a battery for storage. PV installations constitute a long-term and relatively expensive investment. Therefore, it is essential that an exact design of a certain PV installation is carried out. In order to be able to design a PV installation extensive and precise information of a wide range of parameters are required, e.g. climatic data, characteristics for PV-modules, configuration of PV-panels, placing of PV-panels, load on PV-panels, current inverter data, the wanted electricity production over a year etc. On basis of this information it will be possible, via a computer and relevant software, with considerable accuracy to simulate the yield of a certain PV installation. Simulations like this can be calculated by knowledge centres and consulting engineers. The technique of a PV-installation is based on the photovoltaic effect: if light (photons) hits a solar cell, electrons are released out of the crystal structure of the semiconductor material. This process results in an electrical current. The main components of a PV-system are the solar cell, the solar module and the inverter. The solar cell is the part of the installation, in which the transformation of light into electric current takes place. More than 95 per cent of all solar cells that are produced in the world are made of Silicium. In order to get a useful performance, mostly 30 – 36 solar cells are put together to a solar module. The totality of the modules is called solar generator. The voltage of the PV- installation depends on the number of modules connected in series, whilst the number of modules connected parallel determines the electrical current. The inverter creates the connection between the solar generator and the distribution net. As the produced electric is direct current, the inverter has to transfer it to alternating current, in order to deliver it to the public power supply system. The performance (measured in %) of a PV-installation depends on different factors. These factors are apart from the position the slope, the orientation, the performance ratio and the efficiency of the inverter. Estimated actual efficiency of modules (modules ...

The term “Trade Fixtures” shall mean Lessee’s machinery and equipment that can be removed without doing material damage to the Premises. The term “Alterations” shall mean any modification of the improvements, other than Utility Installations or Trade Fixtures, whether by addition or deletion. “Lessee Owned Alterations and/or Utility Installations” are defined as Alterations and/or Utility Installations made by Lessee that are not yet owned by Lessor pursuant to Section 8.4.1.

Lessee shall not cause or permit any Hazardous Substance to be spilled or released in, on, under or about the Premises (including through the plumbing or sanitary sewer system) and shall promptly, at Lessee’s expense, take all investigatory and/ore remedial action reasonably recommended, whether or not formally ordered or required, for the cleanup of any contamination of, and for the maintenance, security and/or monitoring of, the Premises, the elements surrounding same, or neighboring properties that was caused or materially contributed to by Lessee, or pertaining to or involving any Hazardous Substance and/or storage tank brought onto the premises by or for lessee or under its control. Lessee, in keeping the Premises in good order, condition and repair, shall exercise and perform good maintenance practices. Lessee’s obligations shall include restorations, replacements or renewals when necessary to keep the Promises and all improvements thereon or a part thereof in good order, condition and state of repair. If Lessee occupies the Premises for seven (7) years or more, lessor may require Lessee to repaint the exterior of the buildings on the Premises as reasonably required, but not more frequently than once every seven (7) years. (b) Lessee shall, at Lessee’s sole cost and expense, procure and maintain contracts, with copies to Lessor, in customary form and substance for, and with contractors specializing and experienced in, the inspection, maintenance and service of the following equipment and improvements, if any, located on the Premises: (i) heating, air conditioning and ventilation equipment, (ii) boiler, fired or unfired pressure vessels, (iii) fire sprinkler and/or standpipe and hose or other automatic fire extinguishing systems, including fire alarm and/or smoke detection.

  • Software Installation The AGENCY shall request approval in writing from the COUNTY prior to installation of any software on COUNTY computer equipment. All software installations must be supervised by COUNTY technical support staff and proof of licensing is required. Upon completion, the AGENCY is responsible for reconfiguring the computers back to the original state.
