28 Amp Charge Controller $99.99 Solar charge controllers keep your batteries safe. A solar charge controller is required for any solar array of 12 watts or higher. Solar panels are unregulated and can have a voltage higher than necessary to charge 12 volt batteries. The Nature Power 28 Amp Solar Digital PWM Charge Controller will prevent overcharging of batteries by regulating the voltage from a 12 volt solar panel to a safe level for charging 12 volt batteries. Pulse Width Modulation (PWM) control provides higher charging efficiency and maintains a higher battery reserve than standard on/off controllers. Designed for use with 12 volt solar panels this solar charge controller is safe for use with up to 28 amps or 450 watts from a solar array. This controller will also prevent over discharge of your battery as well as protect from high voltage surges short circuit and loss of power through the solar panel at night. A digital LCD screen displays charging current load current and battery voltage in 5 second intervals. Two LED lights display charge function and battery status. A load terminal on the solar charge controller let you dedicate one item to run through the controller when the batteries reach critical voltage the load will be automatically turned off to prevent a dead battery and allow the solar panel to recharge the battery before the load turns on again. This feature helps to prolong the life of your battery. This charge controller may also be used with 24 volt solar panels and batteries. The charge controller is self-adjusting and will automatically set the charge cycle. You can connect multiple solar panels up to one controller so long as you do not exceed 450 watts or 28 amps. The charge controller is meant to be permanently connected to the battery and the solar array even when you are drawing power from the battery. Solar charge controllers should installed close to the battery in a dry and ventilated area. This solar charge controller is covered by a 1 year manufacturers warranty. le |

Extra Terrestrial Photovoltaics: Space-Based Solar Power $9.25 Purchase includes free access to book updates online and a free trial membership in the publisher’s book club where you can select from more than a million books without charge. Excerpt: Space-based solar power (SBSP) (or historically space solar power- SSP) is a system for the collection of solar power in space, for use on Earth. SBSP differs from the usual method of solar power collection in that the solar panels used to collect the energy would reside on a satellite in orbit, often referred to as a solar power satellite (SPS), rather than on Earth’s surface. In space, collection of the Sun’s energy is unaffected by the various obstructions which reduce efficiency or capacities of Earth surface solar power collection. The World Radiation Centre’s 1985 standard extraterrestrial level for solar irradiance is 1367 W/m. The integrated total terrestrial solar irradiance is 950 W/m. Extraterrestrial solar irradiance is thus 144% of the maximum terrestrial irradiance, and has a different radiation profile, including wavelengths blocked by the atmosphere. A major interest in SBSP stems from the length of time the solar collection panels can be exposed to a consistently high amount of solar radiation. For most of the year, a satellite-based solar panel can collect power 24 hours per day, whereas a terrestrial station can collect for at most 12 hours per day, if weather permits, and only during peak hours — irradiance under the best of conditions is quite reduced near sunset and sunrise. Collection of solar energy in space for use on Earth introduces two new problems and can alleviate an existing one. First, installation of the collection satellites, and second transmitting energy from them to the surface for use. The first requires upgrading and extension of existing solar panel technologies. Since wires extending from Earth’s surface to an orbiting satellite are neither practical nor currently possible, many SBSP designs have pro… More: |

HQRP 6W Amorphous Silicon Solar Panel PV Module 12V Anodized Aluminum Frame Photovoltaic + Coaster $27.92 Products trademarked HQRP are marketed and sold exclusively by Osprey-Talon. HQRP Amorphous Solar Panels are an effective solution for those who want to use solar panels in the household, during vacation, and for camping or tourism, etc. The structure of the Amorphous-Si PV modules allows the solar panel to charge the battery under poor lightening. Such Amorphous-Si panels not only work longer during the day hours but also are more effective during the winter time. Amorphous-Si PV modules work under high temperatures more efficiently than mono-crystalline silicon PV modules (c-Si) or poly-crystalline silicon PV modules (poly-Si), efficiency of which decreases due to overheating. In general, during the year Amorphous Solar Panels generate 8.1% more watts than mono-crystalline solar panels and 12.5% more watts than poly-crystalline solar panels. |

Manifold micro-channel cooling of photovoltaic cells for high efficiency solar energy conversion systems. $49.99 Several works have been published on concentration of solar radiation by mirrors or lenses onto smaller sized solar panels, which reduce cost and increase conversion efficiency at higher concentration ratio. One of the challenges is active and uniform cooling of high heat flux solar arrays, because conversion efficiency is dependent on device temperatures and drops with increasing temperature.;This research is targeted at cooling small, high concentrated solar cells. Benefits of manifold microchannel are attractive for cooling of electronic devices but have not been studied for cooling of high concentrated solar cells which is the target of this research, where the microchannel can be microfabricated and etched on the backside of the silicon solar cell to form a sealed heat sink with the manifold fabricated in the silicon substrate. This design not only minimizes the pressure drop, but also maximizes the heat transfer and provides uniform temperature across the device. |

SunPower $48 High Quality Content by WIKIPEDIA articles! High Quality Content by WIKIPEDIA articles! SunPower Corporation designs and manufactures high-efficiency silicon solar cells, roof tiles and solar panels based on a silicon all-back-contact solar cell invented at Stanford University. SunPower Corporation is publicly traded on the NASDAQ as SPWRA and SPWRB. SunPower Corporation is a component of the Dow Jones Oil and Gas Index DJUSEN.SunPower 125mm-wide single-crystal silicon solar cells are based on a rear-contact design that eliminates front-side metallization, maximizes the working cell area, eliminates redundant wires and makes automated production easier. Forming the junction at the rear of the cell, combined with a clever surface treatment, allows it to trap and convert much more of the available photons into mobile electrons – yielding a jump in efficiency. The cell employs several other tricks to boost efficiency, including an oxide passivation layer on the backside to deny regions for unwanted hole-electron recombination. |
