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.

he photovoltaic effect was experimentally demonstrated first by French physicist Edmond Becquerel. In 1839, at age 19, he built the world's first photovoltaic cell in his father's laboratory. Willoughby Smith first described the "Effect of Light on Selenium during the passage of an Electric Current" in a 20 February 1873 issue of Nature. 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.

Q:What are the benefits of using solar panels?
There are several benefits of using solar panels. Firstly, they provide a clean and renewable source of energy, reducing the dependence on fossil fuels and decreasing carbon emissions. Solar panels also help to lower electricity bills by generating free electricity from sunlight. Additionally, they require very little maintenance and have a long lifespan, making them a cost-effective investment. Furthermore, solar panels can increase the value of a property and provide energy independence, especially in remote areas or during power outages. Overall, using solar panels promotes sustainability, saves money, and contributes to a greener environment.
Q:Solar panels would change the world if they were widely available to us especially cheap, it will be worth it in the long end. Money would be saved like housands a year per person on utility costs.
Yes, solar panels could change the world if they were especially cheap--but they're not and may not be cheap for many years, if ever. Lots of new technology could change the world but most of it doesn't. The government doesn't have a very good track record of picking winners in the new technology markets; that's something we should probably leave to the venture capitalists to do--with their own money. The money the government spent on solar panels is gone. Racked up as debt that we'll leave to our children and grandchildren to pay off.
Q:Can solar panels be used to power air conditioning units?
Yes, solar panels can be used to power air conditioning units. Solar panels generate electricity from sunlight, which can be used to power various appliances, including air conditioning units. However, the size and efficiency of the solar panel system needed will depend on factors such as the size of the air conditioning unit and the energy requirements of the building.
Q:I am researching several solar panels to install in my house. I would like to use a 40 watt panel to connect, through a solar battery controller, to a battery or two. I would then like to use the solar panel (40 watts) to charge the battery(ies) for emergency use. Once charged, and when needed, I would like to use the battery(ies), 2 volt deep cycle, to power several LED lamps. Since I am new to solar power I had several questions...Is a 40 watt panel strong/large enough to charge a 2 volt deep cycle battery or two?How long would it take to charge one of these batteries?What would be the expected cost to purchase necessary supplies? (With the solar panel, battery controller, and MC4 cabling I've found I have an expected cost of roughly $00.00 with batteries)Would this be difficult for someone with little experience in this field?
Your demand is high. You require at least 5KVA (5000watts) out put with an appropriate battery storage and inverter..
Q:Can solar panels be used in areas with high levels of air pollution?
Yes, solar panels can still be used in areas with high levels of air pollution. While air pollution can reduce the efficiency of solar panels, they can still generate electricity even in polluted environments. However, regular cleaning and maintenance may be required to ensure optimal performance in such areas.
Q:Why can't they put solar-panels on the blades and sides of the 300-500 foot tall turbines? Wouldn't this increase effeciency? Therefore, boosting pay-back time, profits, energy-output?
It would work better to put the solar panels on the ground beneath the windmills. Land underneath wind farms is perfectly usable for other things, and it gets plenty of sun. But then, if you think about good places for solar panels, parking lots make even more sense yet. There's plenty of em, and people like to park in the shade.
Q:How much space do I need for solar panels?
The amount of space you need for solar panels depends on various factors such as the size and efficiency of the panels, your energy requirements, and the available sunlight. Generally, you'll need around 100 square feet of unobstructed roof space per 1 kW of solar panels. However, it's best to consult with a solar installer who can assess your specific needs and provide an accurate estimation.
Q:Are solar panels suitable for commercial use?
Yes, solar panels are suitable for commercial use. They offer numerous benefits such as reducing electricity costs, providing a reliable source of clean energy, and helping businesses meet sustainability goals. Additionally, advancements in technology have made solar panels more efficient and cost-effective, making them a viable option for commercial establishments of all sizes.
Q:Can solar panels be used for powering electric gates?
Yes, solar panels can be used to power electric gates. Solar panels convert sunlight into electricity, which can be used to operate various electrical devices, including electric gates. This renewable energy source is an environmentally-friendly and cost-effective solution for powering gates in remote or off-grid locations.
Q:Can solar panels be used for air conditioning?
Yes, solar panels can be used for air conditioning. Solar panels generate electricity from sunlight, which can be used to power air conditioning units. By using solar energy, homeowners and businesses can reduce their reliance on traditional electricity sources and decrease their carbon footprint. However, the efficiency and effectiveness of using solar panels for air conditioning may vary depending on factors such as the size of the solar system, location, and energy requirements of the air conditioning unit.
