Product description

 a form of photoelectric cell, defined as a device whose electrical characteristics, such as current, voltage, or resistance, vary when exposed to light. Solar cells are the building blocks of photovoltaic modules, otherwise known as solar panels.

 In 1883 Charles Fritts built the first solid state photovoltaic cell by coating the semiconductor selenium with a thin layer of gold to form the junctions; the device was only around 1% efficient.

Solar cells are described as being photovoltaic irrespective of whether the source is sunlight or an artificial light. They are used as a photodetector (for example infrared detectors), detecting light or other electromagnetic radiation near the visible range, or measuring light intensity.

loss and possible damage because of the reverse bias applied to the shadowed cells by their illuminated partners. Strings of series cells are usually handled independently and not connected in parallel, though as of 2014)individual power boxes are often supplied for each module, and are connected in parallel. Although modules can be interconnected to create an array with the desired peak DC voltage and loading current capacity, using independent MPPTs (maximum power point trackers) is preferable. Otherwise, shunt diodes can reduce shadowing power loss in arrays with series/parallel connected cells.[citation needed]

Q:Is there such a thing as portable solar panels? Can these be obtained for say a mobile homes / caravans etc.

Q:Can solar panels be damaged by birds or other animals?
Yes, solar panels can be damaged by birds or other animals. Birds may build nests under the panels or peck at the wiring, leading to potential system malfunctions. Similarly, other animals like squirrels or rodents may chew on the wires or cause physical damage to the panels. It is advisable to take preventive measures to protect solar panels from such animal interference.
Q:Can solar panels be used to heat water?
Yes, solar panels can be used to heat water. Solar thermal systems, also known as solar water heaters, use sunlight to heat water and are more efficient at heating water compared to using solar panels for electricity generation. These systems capture the sun's energy and transfer it to a fluid, which then heats the water for various applications such as domestic use, swimming pools, and commercial purposes.
Q:How much energy can solar panels generate?
The amount of energy that solar panels can generate depends on various factors such as the size and efficiency of the panels, the location and climate conditions, and the amount of sunlight available. In general, a typical solar panel can produce around 250 to 400 watts of power per hour under optimal conditions. However, the overall energy output can vary significantly, and larger solar installations can generate much higher amounts of electricity.
Q:Can someone explain to me how solar panels can be used as modern architectural attributes? please help
They aren't considered attributes - electrical solar panels are expanses of gray and aluminum covered with glass and water heating panels are expanses of black covered with glass. To cover the cost of investment they must be mounted at the best angle for the location and climate throughout the year and therefore may dictate the form of the roof (if sloped as on residences) or may not be visible in an architectural sense (if positioned on a flat roof of a commercial building.) No matter where placed, provision has to be made for safely accessing them for repair and maintenance.
Q:I am in need of solar panels and the batteries that I can store the energy in. I need to be able to run a laptop, cell phone, and LED lights from it. When I research I see all sorts of options with regards to watts, VMPs, and AMPs. I also see that I may need a controller, an inverter, and various other components. Can anyone help me through these terms and what i need to know in order to efficiently generate and store the electricity. Thanks
Unlike what most people seem to think, solar panels are not advanced enough to power day to day objects that we use, with the sun that we see in a day. You would need mass amounts of panels and equipment. IF there is a smaller solutions (which I doubt would do what you're asking yet) it would cost thousands of dollars. Panels are not there yet, and the ones that are, are still in development or being guarded from release to the public. The most you'll get out of a few hundred bucks and panels is a lit garden for a few hours at night. Go buy rechargeable batteries.
Q:How much does it cost to replace a solar panel?
The cost of replacing a solar panel can vary depending on several factors such as the size, type, and quality of the panel, as well as any additional installation or labor costs. On average, the cost can range from a few hundred dollars for a small residential panel to several thousand dollars for a larger commercial panel. It is always best to consult with a solar panel installer or supplier to get an accurate estimate based on your specific needs and requirements.
Q:Can solar panels be installed on a pergola or gazebo?
Yes, solar panels can be installed on a pergola or gazebo. The flat or sloping roof of a pergola or gazebo provides a suitable surface for mounting solar panels. This allows for the utilization of solar energy while also providing shade and protection from the elements.
Q:I want to plug my solar system battery bank into my transfer switch on my cabin when not using a generator. The transfer switch will handle 220 volt from my generator. How do I get a 220 volt inverter that runs 60 hz or do all of them run 50 hz.I see plenty of 20 volt 60 hz. I'm at the point of needing to order one and I'm not sure.
Stand Alone solar panel inverters function to change direct current (DC) from a battery to Alternating Current (AC). Stand alone inverters, which range from around 00 watts to as much as 8000 watts, are used to power a vast variety of personal or small business projects. Lower watt stand-alone inverters are often used to power laptop computers, whereas high-watt stand-alone inverters could be used to help power an entire household. In order to calculate what class of inverter you need for use with your solar panel, you will first have to determine the maximum sum of all of the Alternating Current loads in your project (or home). How to calculate the wattage you need from your stand-alone solar panel inverter
Q:What is the typical warranty period for solar panels?
The typical warranty period for solar panels is around 25 years.
