New Solar Panels
Advances in solar photovoltaic panels are happening at a fast and furious rate. Plus, the newest panels should have an even longer life expectancy than the older models--older panels have started to turn brown in the clear substrate the solar cells are mounted in, reducing their power output. This problem has been solved by using new plastics in the manufacturing process. The biggest advances in new solar panel technology recently have been in power density--the newest panels are the same size as older models, but put out more power per square foot.

New state rebate shines light for San Diego consumers going solar.
SAN DIEGO - Rising electric rates, incentive programs, and environmental concerns have an ever-increasing number of San Diego County residents and businesses seriously thinking about going solar.
Solar power, or photovoltaics, has become an increasingly attractive method of generating power as local consumers and businesses grapple with growing energy demands and tightening budgets. Solar electricity offers businesses a way to protect themselves against this uncertainty and more importantly reduce a fixed capital expense.
San Diegans have more incentive than ever to go solar after state utility regulators in early 2006 passed a $3 billion dollar rebate program to subsidize the installation of 1 million rooftop systems.

The Basics of Solar Power:
Using solar power to produce electricity is not the same as using solar to produce heat. Solar thermal principles are applied to produce hot fluids or air. Photovoltaic principles are used to produce electricity. A solar panel (PV panel) is made of the natural element, silicon, which becomes charged electrically when subjected to sun light.
Solar panels are directed at solar south in the northern hemisphere and solar north in the southern hemisphere (these are slightly different than magnetic compass north-south directions) at an angle dictated by the geographic location and latitude of where they are to be installed. Typically, the angle of the solar array is set within a range of between site-latitude-plus 15 degrees and site-latitude-minus 15 degrees, depending on whether a slight winter or summer bias is desirable in the system. Many solar arrays are placed at an angle equal to the site latitude with no bias for seasonal periods.
rating vThis electrical charge is consolidated in the PV panel and directed to the output terminals to produce low voltage (Direct Current) - usually 6 to 24 volts. The most common output is intended for nominal 12 volts, with an effective output usually up to 17 volts. A 12 volt nominal output is the reference voltage, but the operating voltage can be 17 volts or higher much like your car alternator charges your 12 volt battery at well over 12 volts. So there's a difference between the reference voltage and the actual operating voltage.

Solar Roof Tiles
These inexpensive solar panels don't make as much power as their big brothers. But because of the price and simplicity of the rack used for mounting and wiring them, you can cover your entire roof with panels (or at least the south-facing part).
Rather than mounting separate solar panels on a rack on top of a roof, BIPV shingle designs interlock with roof tiles and shingles to provide an aesthetic, seamless look

Prism Solar Technologies, Inc.
manufactures a new type of photovoltaic module that uses transparent holographic optical elements in its design. This innovative, patented holographic technology, collects and spectrally selects useful wavelengths from the sun and focuses them onto the cell to create electricity.
Multiplexed Spectral Confinement
Increasing the optical efficiency increases the structures ability to trap more of the light by better controlling the angles that the light is diffracted within the laminate. Through this process, Prism Solar can tap the sunlight at its most advantageous point in the spectrum.
