- Q:Can solar panels be used in areas with limited sunlight?
- Yes, solar panels can still be used in areas with limited sunlight. While solar panels are most effective in areas with abundant sunlight, advancements in technology have made it possible to generate some amount of electricity even in areas with limited sunlight. Additionally, solar panels can still be viable in these areas if combined with energy storage solutions or connected to the grid, allowing for a more reliable and consistent electricity supply.
- Q:How do solar panels impact air pollution?
- Solar panels have a positive impact on air pollution as they produce clean, renewable energy without emitting any harmful pollutants or greenhouse gases. By reducing the reliance on fossil fuels for electricity generation, solar panels help to decrease air pollution, improve air quality, and mitigate the harmful effects of climate change.
- Q:what kind of degree do i need to get in order to know everythin about installing solar panels for houses?
- boots on the roof is one of the classes , around phoenix it it offered at rio salado college, there their so theres a place to start. I have had 2 different people check for me and from what i understand i can install the panels but a licensed electrition has to connect to the meter
- Q:I was wondering if they create other forms of energy besides electrical that is unwanted. Like heat due to the friction of something, or sound. Also why is a solar panel not able to collect 00% of the energy that is striking its panels. And how could the efficiency of this be hypothetically improved.
- figure it out for us
- Q:Any feedback on solar panels?
- Solar panels are very good. Although they may start off expensive, they will soon make up for the money spent. But they will only be useful when facing south and in sunny-ish countries. :)
- Q:Can the solar panels available be coated with a material (to improve it's looks) and not alter it's efficiency?
- No. The only coatings I am aware of are those that reduce reflection so more light gets through the protective surface to the actual cells. Anything thing that affects appearance is going to be reflecting light back to the viewer and the photons of that light are not available for electricity or heat. If the appearance of the panels offends you, then they need to be concealed by a fence of panels around them that do not throw shadows on the panels.
- Q:Can I add reflectors or mirrors around the solar panels to increase the power they generate?
- You could (an example of concentrating sunlight is called cloud gain, where the edge of a cloud will intensify sunlight as it passes between the sun and your panels), but that will make your panels run hotter and will probably reduce their life. It's better from a system design standpoint to simply get another panel or two. DK
- Q:How does the size of a solar panel affect its performance?
- The size of a solar panel directly affects its performance as a larger panel can capture more sunlight and generate a higher amount of electricity. A larger surface area allows for more solar cells to be integrated, resulting in increased energy production. Additionally, a larger panel can accommodate more efficient components and have a lower resistance, leading to improved overall performance.
- Q:Can solar panels be installed on a convention center or event venue?
- Yes, solar panels can be installed on a convention center or event venue. In fact, many convention centers and event venues are embracing renewable energy solutions, including solar power, to reduce their carbon footprint and lower electricity costs. Installing solar panels can provide a reliable and sustainable source of energy, making it an ideal choice for these large-scale facilities.
- Q:I just connected my 5 Watt 2V solar panel directly to my 300 Watt 2 inverter. It worked for about 2 minutes then it popped (sparks, smoke etc)! What the hell did I do wrong? I thought the solar panel was 2 volts? Can someone with experience with these things help me out?
- An 300W inverter will draw 25 amps from a car battery but the solar panel will only produce about 4 amps. By drawing too much power with the inverter you lowered the voltage so much in the panels wiring that the amp rating on the internal wiring was exceeded and they melted. Next, time run the panel to a voltage regulator, then the regulator to a car battery, then the battery to the inverter.
