See all Physical Science articles You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the solar revolution for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately ,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.

Q:Can solar panels be used in countries with limited sunlight?

Yes, solar panels can still be used in countries with limited sunlight. While solar panels are most effective in regions with abundant sunlight, they can still generate electricity in areas with less sunlight. Even countries with limited sunlight exposure can benefit from solar energy by utilizing advanced solar technologies and optimizing panel placement to maximize energy production. Additionally, solar panels can still generate electricity on cloudy or overcast days, although at a reduced efficiency compared to sunny days.

Q:How do solar panels perform in areas with high pollution levels?

Solar panels are affected by high pollution levels as the presence of pollutants in the air can reduce their overall performance. The efficiency of solar panels decreases due to the reduced sunlight reaching the surface of the panels. Additionally, the accumulation of dust and particles on the surface of the panels can further hinder their performance by blocking sunlight. Regular cleaning and maintenance can help mitigate some of these effects, but high pollution levels can still have a negative impact on solar panel performance.

Q:Say if i had a 2KW system is thtat just one big solar panel or does the whole system have little solarpanels together.?

Solar panels are arrays of individual solar cells connected in series and parallel, and.. A high quality, monocrystalline silicon solar cell, at 25 °C cell temperature, may produce 0.60 volts open-circuit (Voc). The cell temperature in full sunlight, even with 25 °C air temperature, will probably be close to 45 °C, reducing the open-circuit voltage to 0.55 volts per cell. The voltage drops modestly, with this type of cell, until the short-circuit current is approached (Isc).

Q:Can solar panels be used on commercial buildings?

Yes, solar panels can be used on commercial buildings. In fact, many businesses are increasingly installing solar panels on their rooftops to generate clean and sustainable energy. This helps them reduce their reliance on traditional energy sources, lower their electricity bills, and contribute to a greener environment. Additionally, government incentives and tax benefits often make solar panel installations a financially viable option for commercial buildings.

Q:Can solar panels be installed on a pergola or awning?

Yes, solar panels can be installed on a pergola or awning. In fact, these structures can provide an ideal platform for solar panel installation, as they offer ample space and exposure to sunlight. Additionally, installing solar panels on a pergola or awning can help to maximize energy production while also providing shade and protection from the elements.

Q:First of all is it possible? I do not know how much electricity my dehumidifier but could someone give me an idea of how much this would cost to do? A link to a solar panel or equipment that would do the job would be nice too.Thanks in advance.

Great! The general steps are: . Determine how much power your humidifier uses (watts). Multiply the amperage x 5 (Assuming you're in the U.S.) 2. Determine what size solar panel you need (this will be in watts as well). Consider that the rating for a solar panel is optimal. That means that's the best it will be in direct sunlight. 3. Determine if you want a battery in the system. A battery will store energy from the solar panel so you can use it later. Helps for cloudy days or when the panel otherwise doesn't output the same power as the humidifier uses. 4. Figure out the right charge controller. You need to regulate the power from the solar panel into either the humidifier or the battery setup. 5. Tie it all in together, using proper electrical connections. It can be complicated, but its certainly a good feeling to get power from the sun. Good luck!

Q:Can solar panels be used in developing countries?

Yes, solar panels can definitely be used in developing countries. In fact, they are increasingly being adopted as a sustainable and affordable source of energy in many developing nations. Solar power offers numerous benefits such as reducing reliance on expensive fossil fuels, providing electricity to remote areas without access to the grid, and promoting economic growth by creating job opportunities in the renewable energy sector. Additionally, solar panels can be easily installed and maintained, making them a viable solution for powering homes, schools, healthcare facilities, and other essential infrastructure in developing countries.

Q:How much energy can be generated from a solar panel on a clear, bright summer's day for example?

Well, the maximum amount of energy you can receive with 00 percent efficiency is kilowatt per square meter. This is the energy that hits the Earth's surface. The best commercially available panels are 20-30 percent efficient. Cutting edge technology has gotten this percentage up to 50 percent, but you can't buy these for your home. If you're curious about efficiency, check out a panel's dimensions, find the area in square meters, and use that along with its Watts (divide by 000 to get kilowatts) to get your answer.

Q:How do solar panels impact the local economy?

Solar panels can have a positive impact on the local economy in several ways. Firstly, the installation and maintenance of solar panels create jobs, boosting employment opportunities in the area. Additionally, the use of solar energy reduces dependency on traditional energy sources, which can lead to lower energy costs for businesses and residents, freeing up more money to be spent locally. Furthermore, solar panel installations often require local partnerships and suppliers, supporting local businesses and stimulating economic growth. Ultimately, the adoption of solar panels contributes to a more sustainable and resilient local economy.
