Solar panels are an effective source of generating solar power. With the advancement in technology, the solar panels created today can take care of your bigger needs too. These not only save the environment but are also beneficial for the direct user. When used for commercial purposes, solar power saves time, avails government rebates, provides long term reliability, costs less maintenance, and saves you form giving the utility charges. When used for residential purposes, solar power cuts off your electricity bills, provides you a reliable source of electricity for a long time, and you can also avail the solar panel rebate.

Solar panels are one time investment for your home or business. They are a continuous source of electricity without having the possibility of increasing rates in future.

“A technological feat that will charm the promoters of renewable energy. The Boeing-Spectrolab, under the Department of Energy U.S., just tune photovoltaic modules (which convert sunlight directly into electricity) with a yield, ie the ratio of electrical energy and solar energy received reaches 40.7%. The last record, set by the same manufacturer, was 37%. Europe, which developed the Full Spectrum project which is associated with the CEA, does not exceed 35.2%.

These returns are noteworthy when we consider those obtained with traditional PV panels based on silicon, whose ceiling is currently at 26% in the laboratory, and only 17% for industrial production. While conventional cells will leverage the natural sunlight, the Boeing-Spectrolab integrated optical concentrators (Fresnel lens) to focus sunlight. They consist of different layers of semiconductor metals, including gallium arsenide “doped” with Indian, Phosphorus, Arsenic or Aluminum.

These systems, called “Multijunction” leverage the whole spectrum of wavelength of light, from infrared to ultraviolet. Philippe Malbranche, the CEA estimates that a yield of 45% is theoretically possible. But its components are extremely expensive, although the DOE provides for the return of the kWh price will drop to 6 or 7 cents. Concentration modules are limited primarily to regions of strong direct sunlight. “
