Solar panels in the sun
Solar cells are often electrically connected and encapsulated as a module. Photovoltaic modules often have a sheet of glass on the front (sun up) side, allowing light to pass while protecting the semiconductor wafers from the elements (rain, hail, etc.). Solar cells are also usually connected in series in modules, creating an additive voltage. Connecting cells in parallel will yield a higher current. Modules are then interconnected, in series or parallel, or both, to create an array with the desired peak DC voltage and current.The power output of a solar array is measured in watts or kilowatts. In order to calculate the typical energy needs of the application, a measurement in watt-hours, kilowatt-hours or kilowatt-hours per day is often used. A common rule of thumb is that average power is equal to 20% of peak power, so that each peak kilowatt of solar array output power corresponds to energy production of 4.8 kWh per day (24 hours x 1 kW x 20% = 4.8 kWh).To make practical use of the solar-generated energy, the electricity is most often fed into the electricity grid using inverters (grid-connected photovoltaic systems); in stand-alone systems, batteries are used to store the energy that is not needed immediately.Solar cells can also be applied to other electronics devices to make it self-power sustainable in the sun. There are solar cell phone chargers, solar bike light and solar camping lanterns that people can adopt for daily use

EDITORS COMMENTS
This print showcases a stunning array of solar panels basking in the warm glow of the sun. Each solar cell is meticulously connected and encapsulated as a module, ensuring efficient energy conversion. The front side of these photovoltaic modules is protected by a sheet of glass, allowing sunlight to pass through while safeguarding the delicate semiconductor wafers from harsh weather conditions like rain or hail. To maximize power output, these solar cells are interconnected either in series or parallel configurations within each module, creating an additive voltage or higher current respectively. These modules are then further interconnected to form an impressive array with the desired peak DC voltage and current. The true measure of this solar array's capability lies in its power output, which can be quantified in watts or kilowatts. To estimate its potential energy production for various applications, watt-hours, kilowatt-hours, or kilowatt-hours per day measurements are commonly used. As a general rule of thumb, average power typically amounts to 20% of peak power. This means that every peak kilowatt generated by this solar array corresponds to an energy production equivalent to 4.8 kWh per day. In order to make practical use of this abundant solar-generated energy, it can be seamlessly integrated into the electricity grid using inverters for grid-connected photovoltaic systems. Alternatively, stand-alone systems employ batteries to store excess energy that isn't immediately needed. Beyond traditional applications, such as powering homes and businesses on the grid scale level; innovative uses abound for solar cells in everyday life too! From self-power sustainable electronics like cell phone chargers and bike lights to camping lanterns that harness sunlight during outdoor adventures – there's no limit to how we can embrace clean and renewable energy sources like these remarkable solar cells captured beautifully by Detlev van Ravenswaay from Science Photo Library.
