Bypass Diode

Solar Panel Shading

Bypass diodes are a must for any photovoltaic solar panel as they protect the panel from overheating when shaded by trees, leaves or debris. When one solar cell of a panel becomes shaded while the other solar cells around it are illuminated by sunlight, hot spots can be created leading to overheating and eventual destruction of the affected shaded cell. A bypass diode is commonly placed on sub-strings of the photovoltaic panel usually one diode per 15 to 20 photovoltaic cells to maintain the load current delivery of the panel

Pico Solar Systems

Pico solar systems use small scale photovoltaic panels for lighting and battery charging applications. There are still many people around the world who have no access to an electricity grid connection or require a portable energy source for camping or RV’s so pico solar systems can help in provide the essential energy required to fill this gap. Pico solar systems of only a few watts have experienced significant development in the past few years, combining very efficient LED bulbs with sophisticated charge controllers and energy efficient storage batteries providing power for lighting, phone charging or powering a radio, etc.

How to Size a Solar System Please share/bookmark with: How to Size a Solar System Correctly Solar Panels are becoming more common place and investing in a solar photovoltaic system is a smart solar solution for most homeowners. This now proven and reliable technology offers long-term performance with low maintenance. The latest solar panels and PV systems are cheaper, easier to install, maintain and operate more efficiently than ever before so its important to know how to size a solar

Solar Cell I-V Characteristic

Solar Cell I-V Characteristic Please share/bookmark with: Solar Cell I-V Characteristic and the Solar Cell I-V Curve Solar Cell I-V Characteristic Curves show the current and voltage ( I-V ) characteristics of a particular photovoltaic ( PV ) cell, module or array giving a detailed description of its solar energy conversion ability and efficiency. Knowing the electrical I-V characteristics (more importantly Pmax) of a solar cell, or panel is critical in determining the device’s output performance and solar efficiency. Photovoltaic solar cells convert the

Solar Cell Turns Photons into Electrons

Solar Cell Turns Photons into Electrons Please share/bookmark with: The Solar Cell Turns Photons into Electrons Photovoltaic cells, or PV’s for short, are magical things which convert light energy, usually from the sun into electrical energy. Solar cells are made from semiconducting materials such as silicon (Si), the second most abundant material in the world after oxygen, which is used to convert the sunlight’s photons into electrons. This conversion process as effective as it is produces no harmful waste or

Solar Panel Review

Solar Panel Review Please share/bookmark with: Solar Panel Review of 10 to 80 Watt Solar Panels This solar panel review section deals mainly with the smaller sized photovoltaic panels delivering 80 watts or less of free solar energy. Solar photovoltaic (PV) panels of less than 100 Watts are generally designed for off-grid or stand alone portable applications operating at 12 Volts. These low-to-mid wattage range panels are robust, compact and portable being widely used for leisure applications involving 12 volt
