Q: What size of system would I need to get if I use on average 500 kilowatt hrs a month I would like to do a tie in grid system I live in the states south central area of States any info or links to sites would be wonderful I am interested in this type of energy soure thank you: First find out from your electric company whether they allow grid tie systems. IF so then they can help you figure out what you need.

Q: What is the impact of hailstorms on solar panels?: Hailstorms can potentially cause damage to solar panels, particularly if the hailstones are large and the panels are not adequately protected. The impact can range from minor scratches and dents, which may not affect the overall performance of the panels, to more severe damage that can impair their functionality. However, advancements in technology and the use of durable materials have made modern solar panels more resistant to hail damage. Proper installation and maintenance, including the use of protective measures like tempered glass or hail guards, can further minimize the impact of hailstorms on solar panels.

Q: Can solar panels be integrated into building materials?: Yes, solar panels can be integrated into building materials. This innovative approach, known as building-integrated photovoltaics (BIPV), allows solar panels to be seamlessly incorporated into various architectural elements such as roofs, facades, windows, and even entire building structures. BIPV offers a dual function by serving as both a source of renewable energy and a structural component, enabling buildings to generate sustainable electricity while maintaining aesthetic appeal.

Q: How much space do I need for solar panels?: The amount of space required for solar panels depends on various factors such as the size and type of panels, the efficiency of the panels, and the energy needs of your household or facility. On average, a 1 kW solar panel system typically requires around 100 square feet of space. However, it is best to consult with a solar installer or expert who can assess your specific requirements and provide accurate information regarding the space needed for solar panels.

Q: This is for my science project and i cannot figure it outWe assumed that blue light shining on a solar panel would give off the higher volt reading because it has the shortest wavelength and the highest energy, but it was actually the lowest. Why does this happen? Im very confused And cant find the answer anywhere.... ，thank you!!: It is based on what the solar panel is made out of. Many of them will generate electric into the NIR region.

Q: Okay, I think I understand what I'm doing, but I want to set up some solar panels on the roof of my garage, the building that gets the most sun, and I want to make sure all my math is correct in determining number of megawatts per year. However, my knowledge of electrical terms in quite n00bish, to say the least.Here is what I think I should be doing.The solar cells come at .75 Watts average power.I will install 4 panels of 64 cells each, with a total of 256 cells.: For comparison, 36 of these make a normal 2V x 50W panel. Note they are not tabbed. This means you have to find a way to connect them yourself. The tabs are probably spot welded on by the suppliers. A supplier below has kits of these with tabs, as needed to connect them together. These are not suitable for grid connect, because the higher voltage needed makes do it yourself panels a dangerous and litigious thing to have on your roof. Maybe you could buy a smaller pack from the link below to compare tabbed and untabbed and work out what to do. Your power calculation is a bit incorrect because the sun is only present some of the time. The 36 cell module would produce 50W when square on to the full sun. The sun may be out for around 2h a day in some places and times of the year. However it is the equivalent of 5h full sun, because of the changing angle throughout the day. Look this up on the internet for your region. Temperate zones may be a lot less. One pack in your link is 36x3 = 08 cells. Thus 50W per pack x 5h a day gives 750Wh per day and 274KWh/y. In reality it will always be less because of regions, weather, clouds, dust, inefficiencies, aging of cells.

Q: so i told my dad to buy solar panels and he wants to see how much money u can save we pay $00 and i dont want quot;You don't need solar panelshow much would my fmaily save?: First, to answer your question we would need to know how much power you use, the solar capability of the area you live in, and several other facts.

Q: How long does it take a 5 watt, 2 volt solar panel to charge a 2 volt R.V. battery?: depends on the sunlight. And on the size of the battery. But it may never charge, as you need at least 5 volts to charge a 2 volt battery. So unless the sunlight is bright enough to generate 5 volts, all you will do is discharge the battery through the solar panel. But a large battery is 00 amp hours of capacity. Even if you had a 5 volt 5 watt panel, that generates only amp at most, so it would take over 00 hours to charge that size battery. .

Q: Can solar panels be used in agriculture?: Yes, solar panels can be used in agriculture. They provide a renewable and clean source of energy that can power various agricultural activities such as irrigation systems, lighting, and machinery. Additionally, solar panels can be installed on agricultural buildings or unused land, allowing farmers to generate their own electricity and reduce their carbon footprint.

Q: Can solar panels be used in areas with high levels of dust?: Yes, solar panels can still be used in areas with high levels of dust. While excessive dust can reduce the efficiency of solar panels by blocking sunlight, regular cleaning and maintenance can help mitigate this issue. Additionally, advancements in technology, such as self-cleaning panels or coatings that repel dust, are being developed to further enhance the performance of solar panels in dusty environments.
