SPECIALTY AREAS
We have many 'specialty areas' - when it comes to new products, updated installation and specific knowledge - healthcare and the like - we are the team for you! We recently completed a Fire Station project, installing a photovoltaic system. Here is summary of that project, along with general information about the technology - .
PHOTOVOLTAIC What is Photovoltaic? Scroll down to Photovoltaic System Information.
O'Neill Electric Inc has experience with PHOTOVOLTAIC systems; having completed a new installation at Fire Stations 16 & 25, here in Portland. We look for innovative ways to help clients utilize power efficient systems. For more information on PHOTOVOLTAIC systems, give us a call.
As for panels, we work with several manufacturers, and we are a distributor for the Eagle-1 Solar Power Products. A few of their applications are seen below.
PHOTOVOLTAIC SYSTEM INFORMATION This information is provided by the Photovoltaic Association: Photovoltaic means electricity from light. Photovoltaic systems use daylight to power ordinary electrical equipment, for example, household appliances, computers and lighting. The photovoltaic (PV) process converts free solar energy - the most abundant energy source on the planet - directly into electricity. Note that this is not the familiar solar thermal technology used for heating and hot water. A PV cell consists of two or more thin layers of semi-conducting material, most commonly silicon. When the silicon is exposed to light, electrical charges are generated and this can be conducted away by metal contacts as direct current (DC). The electrical output from a single cell is small, so multiple cells are connected together and encapsulated (usually behind glass) to form a module (sometimes referred to as a "panel"). The PV module is the principle building block of a PV system and any number of modules can be connected together to give the desired electrical output. PV equipment has no moving parts and as a result requires minimal maintenance. It generates electricity without producing emissions of greenhouse or any other gases, and its operation is virtually silent. PV
systems supply electricity to many applications, ranging from systems supplying
power to city buildings (which are also connected to the normal local
electricity network) to systems supplying power to garden lights or to remote
telecom relay stations. Grid connect PV systems are often integrated into buildings. PV technology is ideally suited to use on buildings, providing pollution and noise-free electricity without using extra space. The use of photovoltaics on buildings has grown substantially in the last few years. Stand-alone photovoltaic
systems have
been used for many years in the UK to supply electricity to applications where
grid power supplies are unavailable or difficult to connect to. Examples include
monitoring stations, radio repeater stations, telephone kiosks and street
lighting. There is also a substantial market for PV technology in the leisure
industry, with battery chargers for boats and caravans, as well as for powering
garden equipment such as solar fountains. These systems normally use batteries
to store the power, if larger amounts of electricity are required they can be
combined with another source of power - a biomass generator, a wind turbine or
diesel generator to form a hybrid power supply system. SOLAR POWER Eagle-1 supplies environmental products for the 21st century. The Model HLS-35E/!@ is a self contained Solar Power Highway/Street Lighting System that uses the sun for energy. It produces an extremely bright white light (closet to the color of sun light). The lamp will automatically turn on at dusk and off again at the end of 12 hours (or at sunrise). Custom settings are possible. This lighting system is one of many products offered by Eagle-1. Give us a call should you want pricing or additional information.
