Q: I need to reduce the average monthly home electricity bill by powering some of the household appliances using solar panels. Can I use a 250 watt solar panel to power a medium sized upright fridge?: Well you might reduce your bills, but you wont get your capital back for many years. Do you have LED lighting, I have, every-time one of my compact flourescent bulbs blew I would replace it with an LED, after two years most of my lighting is LED, a good investment I think. What devices do you have, heating and cooking is better with gas (much cheaper) Think about better insulation for wintertime.

Q: Can solar panels be used to power outdoor lighting?: Yes, solar panels can be used to power outdoor lighting. Solar panels convert sunlight into electricity, which can be stored in batteries or used directly to power outdoor lights, such as garden lights, streetlights, or security lights. This allows for sustainable and cost-effective lighting solutions in outdoor areas.

Q: I want to plug my solar system battery bank into my transfer switch on my cabin when not using a generator. The transfer switch will handle 220 volt from my generator. How do I get a 220 volt inverter that runs 60 hz or do all of them run 50 hz.I see plenty of 20 volt 60 hz. I'm at the point of needing to order one and I'm not sure.: Where is this located? Very few countries use 220 60Hz. Find an inverter that is dual voltage like the reference. Usually the frequency switch is separate from the voltage switch. .

Q: first of all, to be honest i have totally no idea on how a solar panel works.my task is to design something like a solar powered street lamp which store sun energy during day time and convert it into electrical energy then light energy so that the lamp can work during night time.any ideas on how to design the solar panel? which can store enough or more enegry in case there is no sunlight another day. and low cost as well :D: image voltaic panels do no longer shop capability, they basically generate it. in case you opt to shop capability you like a battery economic enterprise of a few sort to get you for the time of the night and each time the sunlight isn't shining. in case you have somewhat extra in the fee selection you would be able to desire to look at a geothermal equipment to your place's heating and cooling needs. they are distinctly useful structures and you'd be able to supplement notwithstanding you like. notwithstanding you do, in spite of the indisputable fact that i'm hoping you have a sturdy construction envelope in place already. image voltaic panels are cool, yet once you have a leaky homestead, you're nevertheless no longer getting the final out of your panels. Do the extra mundane stuff first. Insulation, homestead windows, and climate-tight doorways.

Q: If not how do they give power to a house/a company?: They are powered by the sun. You set them up out side of the house or on the roof and the sunlight shines on them through out the day. It stores the energy into light so when you turn on a light it is from the sun's energy. Plus it can save you on electric bills.

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: There are so many solar panels and kits it is very confusing. I need to know what exactly I would need if I had an underground home with no electricity. I want to be totally off the grid with solar power. Someone please explain to me in simple terms what exactly I need. Maybe give me a link to the right kit for me. Also are they easy to install? Are there instructions that I need to download?Thank you: You okorder ... Depending on your needs, you may have to have these customized for your home, but they at least give you an idea of what's involved.

Q: And how do you choose the best one for the best price?I saw a 400 watt monocrystalline solar panel: The polycrystalline solar panel has a longer life-span and has a higher efficiency. What this means is that from the energy that 'hits' the solar panel, more is caught and used to convert into electrical energy. A polycrystalline solar panel will have an efficiency of about 4%. The monocrystalline solar panel has a similar efficiency but the cells are prone to sunlight, so the efficiency drops over the years.

Q: Ok so i'm writing this research paper on why solar panels are the best way to quot;go greenquot;. I need at least 5-7 reasons why they are good. and a common counterargument that i could defend. I've already come up with incentives and efficiency but i need a few more Please help its very important and worth half my grade: Actually, solar energy IS a good one. It's something we all need to think about, especially when coal and oil become harder to get. Good luck with your paper!
