  2. Charge controller - Wikipedia

    en.wikipedia.org/wiki/Charge_controller

    By way of example, a 150 volt PV array connected to an MPPT charge controller can be used to charge a 24 or 48 volt battery. Higher array voltage means lower array current, so the savings in wiring costs can more than pay for the controller. [citation needed] Charge controllers may also monitor battery temperature to prevent overheating.

  3. Maximum power point tracking - Wikipedia

    en.wikipedia.org/wiki/Maximum_power_point_tracking

    Power/Voltage-curve of a partially shaded PV system, with marked local and global MPP. Maximum power point tracking (MPPT), [1] [2] or sometimes just power point tracking (PPT), [3] [4] is a technique used with variable power sources to maximize energy extraction as conditions vary. [5]

  5. Solar panel - Wikipedia

    en.wikipedia.org/wiki/Solar_panel

    Maximum power point tracking (MPPT) power optimizers, a DC-to-DC converter technology developed to maximize the power harvest from solar photovoltaic systems by compensating for shading effects, wherein a shadow falling on a section of a module causes the electrical output of one or more strings of cells in the module to fall to near zero, but ...

  6. Charge control - Wikipedia

    en.wikipedia.org/wiki/Charge_control

    Charge control is a technology that lets an electric utility control, in real time, the charging of a gridable (plug-in) vehicle, such as a plug-in hybrid (PHEV) or a battery electric vehicle (BEV). Through charge control, the utility is able to postpone charging of the vehicle during time of peak demand .

    Consumer Reports Best Buy Drugs is available free on Consumer Reports Health.org. It compares prescription drugs in over 20 major categories, such as heart disease, blood pressure and diabetes, and gives comparative ratings of effectiveness and costs, in reports and tables, in web pages and PDF documents, in summary and detailed form.

  8. Photovoltaic mounting system - Wikipedia

    en.wikipedia.org/wiki/Photovoltaic_mounting_system

    A solar cell performs the best (most energy per unit time) when its surface is perpendicular to the sun's rays, which change continuously over the course of the day and season (see: Sun path). It is a common practice to tilt a fixed PV module (without solar tracker ) at the same angle as the latitude of array's location to maximize the annual ...

  9. Photovoltaic system - Wikipedia

    en.wikipedia.org/wiki/Photovoltaic_system

    A photovoltaic system, also called a PV system or solar power system, is an electric power system designed to supply usable solar power by means of photovoltaics.It consists of an arrangement of several components, including solar panels to absorb and convert sunlight into electricity, a solar inverter to convert the output from direct to alternating current, as well as mounting, cabling, and ...
