Most parts of a solar module can be recycled including up to 97% of certain semiconductor materials or the glass as well as large amounts of ferrous and non-ferrous metals.Some private companies and non-profit organizations are currently engaged in take-back and recycling operations for end-of-life modules.

Recycling possibilities depend on the kind of technology used in the modules:

    Silicon based modules: aluminum frames and junction boxes are dismantled manually at the beginning of the process. The module is then crushed in a mill and the different fractions are separated - glass, plastics and metals.It is possible to recover more than 80% of the incoming weight.This process can be performed by flat glass recyclers since morphology and composition of a PV module is similar to those flat glasses used in the building and automotive industry. The recovered glass for example is readily accepted by the glass foam and glass insulation industry.

    Non-silicon based modules: they require specific recycling technologies such as the use of chemical baths in order to separate the different semiconductor materials.For cadmium telluride modules, the recycling process begins by crushing the module and subsequently separating the different fractions. This recycling process is designed to recover up to 90% of the glass and 95% of the semiconductor materials contained.[18] Some commercial-scale recycling facilities have been created in recent years by private companies.

Q: Can solar panels be used in conjunction with wind turbines?
Yes, solar panels can indeed be used in conjunction with wind turbines. This combination of renewable energy sources can provide a more reliable and consistent power supply, as wind and solar resources often complement each other. During periods of low sunlight, wind turbines can generate electricity, and during calm periods with low wind, solar panels can continue to produce power. Integrating both technologies can enhance the overall efficiency and effectiveness of a renewable energy system.
Q: What materials are solar panels made of?
Solar panels are typically made of photovoltaic (PV) cells, which are primarily composed of silicon, along with other materials such as metal frames, glass, and encapsulation materials.
Q: I have a 20 watt solar panel that I want to set up. I need to connect it to the solar controller but do not know what cable to use. I plan on adding more solar panels down the line. What would be the best cable to use?
on the controller, it writes which would be related with image voltaic panel which would be related with battery which would be related with load all of it write on the image voltaic controller. only see the controller
Q: What is the warranty on solar panels?
The warranty on solar panels typically ranges from 10 to 25 years, depending on the manufacturer.
Q: are solar panels just a photodiode?A Photodiode converts light into either current or voltage? Right?
yes. Any semiconductor junction will convert light into electrical energy, just shine a light at an LED (connect LED to voltmeter) and you'll see a small voltage produced (if you configure the meter as an ammeter it will develop a very small current). Solar panels are just VERY large surface photodiodes.
Q: Can I add reflectors or mirrors around the solar panels to increase the power they generate?
In the 70's when silicon was really expensive, they played with using fresnel lenses to focus the sunlight on small solar cells but these panels had to be on heliostats and aimed directly at the Sun. These days, with nano-technology, there's a renewed interest in the concept but the fundamental weakness is that there are diminishing returns, at some point, it's just less expensive to have more solar cells.
Q: If this was sold back to the grids what would be the profit i would stand to make per day on energy received in these panels? How did you come up with this answer?
I'm putting in a $00,000 solar wind project on ST Thomas, Virgin Islands so I have some experience here..... ) depends on where you are...the further north the less efficient the panels are because early morning and late afternoon sun hitting at a great angle isn't anywhere near as good as noon hitting perpendicular..........the US Department of Energy has a solar calculator showing how many hours a day over the year you get enough sunlight to actually run the panels....in the Caribbean the answer is 6 so in Wisconsin you might only get 4 really usable hours a day, Nevada 5, Seattle...forget about it..... 2) the panels I'm putting in are ( roughly) 2 x 3 feet...you would need access around all four sides of a panel...you are NOT going to crawl 35 feet across an array to fix a unit in the middle......so lets say you get 35 panels tall ( 70/2) by 2 wide (3 foot with a 3 foot access area between each row = 72/6) or 420 panels. Each puts out 75 watts at max. So you are cranking out 73,500 watt hours, or 73kW. If your local utility buys back ( net metering ) the juice at, say, 20 cents a kWh, you get $4.75 an hour. If you have 4 usable hours a day x 365 x $4.74 you get back something like $20,000 a year. You pay about $7.00 a watt for a panel. The 75 watt panels are, rounding up, $200. each. Times the 420 panels number is $475,000 dollars. Add in about $2,000 for the inverter to change panel volts to power company volts, and maybe another $20,000 for installation you are looking at $500,000 AT LEAST to put in the system you propose. AT $20,000 a year in sales, its 20-25 years payback. Now, you can play with these numbers up and down but you still get the answer of A LOT of money to buy and build and a LONG time till payback.
Q: I am doing a project for school and i need to power a 9v DC motor using a solar panel. Does anyone know places i could get these for not to expensive, and how many volts/watts i would need?
I too want to buy the panels to light up my house.
Q: How do solar panels withstand hail and other extreme weather conditions?
Solar panels are designed to withstand various weather conditions, including hail and extreme weather. They are typically made with durable materials such as tempered glass, which is highly resistant to hail damage. Additionally, the panels undergo rigorous testing to ensure their ability to withstand high winds, snow loads, and extreme temperatures. The frames and mounting systems used to secure the panels also contribute to their resilience against severe weather. Overall, solar panels are built to be robust and reliable, enabling them to endure hail and other extreme weather conditions.
Q: Can solar panels be installed in areas with high levels of saltwater exposure?
Yes, solar panels can be installed in areas with high levels of saltwater exposure. However, it is important to consider the potential effects of corrosion on the panels and their supporting structures. Proper maintenance and regular cleaning of the panels can help mitigate the impact of saltwater exposure and ensure optimal performance and longevity. Additionally, selecting corrosion-resistant materials and utilizing protective coatings can further enhance the durability of solar panels in such environments.
