Q: Can solar panels be used in combination with other renewable energy sources?
Yes, solar panels can be effectively used in combination with other renewable energy sources such as wind turbines, hydroelectric power, or geothermal energy. This combination, known as hybrid renewable energy systems, allows for increased reliability, better utilization of resources, and a more stable power supply.
Q: Are solar panels safe?
Yes, solar panels are safe. They are designed and installed with safety measures in place to ensure their proper functioning and to minimize any potential risks.
Q: How do solar panel power systems work?
The panels soak up the energy from the sun and then convert the energy into power, electricity, etc. They can also store a lot of energy so that we still have power on cloudy days. Does that help? Without more info, its hard to get more specific.
Q: Can solar panels be installed in shaded areas?
Solar panels can be installed in shaded areas, but their efficiency and energy production will be significantly reduced.
Q: I am working on a project and I have to build a house with solar panels. My teacher asked me how would I get solar energy if it is rainy or cloudy? I looked it up but didn't understand. Please help me!!
Being totally honest, the way that most houses connect solar today is alongside their normal power from the power company. If the panels produce more than the house can use, the power company buys the excess electricity. At night, or any time the house needs to draw more than the panels are putting out (including rainy days), power is simply bought from the power company the old way. Between the buying and selling, a house's electric bill for the year could be low, zero, or even negative. The other alternative, useful where there is no power company, is to have batteries. These batteries are very similar to car batteries. During sunny days, the batteries are charged, and when there isn't sun, power is drawn from the batteries. This is inefficient and expensive compared to just using the power company, so people generally only do it if they have to.
Q: My family and I are looking into solar panels for our home. But I'm unsure how it would be priced. This month our home used ,623 kwh. The solar panel company said we should expect $6-$9 per watt used. What would that put as at?
OK, KWH stands for Thousand Watts per Hour. You used ,623,000 watt/hours last month. If you pay $6.00 per watt, your bill would be $9,738,000.00. That's right-$9 million,seven hundred and thirty-eight thousand and 00/00.
Q: Can solar panels be installed on community buildings?
Yes, solar panels can be installed on community buildings. Installing solar panels on community buildings is a popular and effective way to generate clean and renewable energy for the community. It not only helps reduce electricity costs but also contributes to a sustainable and eco-friendly environment.
Q: Can solar panels be installed on parking lots?
Yes, solar panels can be installed on parking lots. In fact, parking lots can provide ample space for the installation of solar panels, making use of the otherwise unused area. This not only generates clean and renewable energy but can also provide shade for vehicles, reducing the need for air conditioning and promoting sustainability.
Q: OK, so if you put solar panels up on a roof, they are busy turning the sun's energy into electricity. So, does that mean the roof (and therefore the house/structure) stays cooler as well? Or does it still get hot, because . . . I dunno, maybe the panels don't convert all the energy, and the spillover still heats up the building.Any links or URLs to scientific answers would be appreciated, but I don't mind hearing from the Average Joe or (Joelle).
I asked the same question once to a PV install during a seminar a few years back, and he explained the following: No, PV panels do not reflect or absorb much heat from going into the building below but there is a reason for this: PV panels that reflect / absorb heat produce less electricity. They are designed to Thermally Transparent. Even worse if installed incorrectly without a good angle and air gap to allow the heat to escape the panels will actually trap this heat and increase the interior temperature of the building below! Below is the scientific analysis that is quite verbose but has two nice graphs at the end. To summarize: Adding PV panels, at best, shaded the building enough to reduce the load of the interior A/C unit by .8 kWh/sq-m/year. The electricity generated by the panels was about 356 kWh/sq-m/year. You can see the big advantage of PV panels is to make power, not reflect heat. Proper insulation is much cheaper and will do a much better job. Don’t worry, I was shocked too, but like anything it makes sense after it is explained.
Q: Okay, me and my friends are going to fix up an old trailer that's out in the woods, we want something to be able to run small electric appliances off of, but it's to far to run power to. How can we make a good but cheap homemade solar panel that we could plug things into? The trailer is in more of a field so it gets plenty of sunlight! Thanks for any help! :)
you cant make solar panels to generate electricity at home. A LOT of high tech equipment is needed. About the cheapest option is to use solar powered garden lights but that is all you'll get is a bit of light.(Google making solar panels) You should be able to make up a windmill powered generator though (but dont expect much power out of something you can make easily) Do some research yourself
