Q:Can solar panels be used in cold climates?
Yes, solar panels can be used in cold climates. While the efficiency of solar panels may slightly decrease in colder temperatures, they can still generate electricity even in freezing conditions. In fact, solar panels can even benefit from the reflection of sunlight off snow, which can increase their output. Additionally, advancements in technology and the use of anti-reflective coatings have improved the performance of solar panels in cold climates.
Q:I want to put a solar panel(s) on my roof. What components do I need besides the solar panels? solar power controller? wires? How do I hook it into my home's electrical system and about how much electricity could I generate and save? Would the panels pay for themselves over time? Any help will be appreciated. Thank you!
The first thing that you have to realize is that solar panels only make DC currant. This is used to charge batteries which when hooked to an inverter will make 20 v. AC. You need a large bank of batteries and a heavy duty inverter to power your house. There is also an automatic switch that will send power back to the utility company when you have excess power available. This is not a small project. Really think this out before you invest a lot of money for nothing.
Q:How much is the cost of solar panels including installation for my home so that I can have low monthly power bills.
Home systems start at $30,000 and go up. There are federal income tax credits to help offset the cost, but you still have to pay up front, more than the average person can afford.
Q:was looking at a few different sites, here is one of them
Building your own panels can be an interesting experiment, but if you are looking for solar panels to provide significant, consistent output, you should buy factory made ones. I get lots of calls from people who built their own panels and get a fraction of the advertised output from them. Plus, factory built panels will last 40 - 50 years, with a 25 year warranty, how sure are you that you can build something that can withstand the outdoors for that long? The price of panels has dropped a lot this year, plus with rebates and tax credits, it's getting more affordable.
Q:How do solar panels affect the overall comfort of a building?
Solar panels can positively impact the overall comfort of a building by reducing energy costs, improving indoor air quality, and providing a more reliable and sustainable source of electricity.
Q:Its cloudy out and i have a solar panel that has 3, .5 volt cells But how do i charge it without sun any other ways?
There okorder Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
Q:How much space is needed to install solar panels?
The amount of space needed to install solar panels varies depending on the size and quantity of panels being installed. On average, a single solar panel requires about 15-20 square feet of space. However, it's important to consider factors like panel orientation, shading, and energy requirements to determine the exact space needed for an installation.
Q:Hi,I am thinking about getting solar panels installed. # I like to cut my electric bill. #2 I like to eliminate my oil boiler and use some sort of electric boiler.I use about 5000-30000 KW per hour( winter-summer). My oil bill is around 600 month winter time. Over all i pay around 4000 a year. My electric bil now is around 2000-2500 year. Is this possible? I live in NY. I heard you can get up to $35000 rebate from LIPA( Electric company) and 2k from federal and 5k from State( is the state or federal every year?, how does that work). Any help is appreciated.

Lots More Information 0. See all Physical Science articles You've most likely visible calculators that experience sun cells -- calculators that certainly not want batteries, and in a few instances do not also have an off button. As lengthy as you have got sufficient mild, they look to paintings eternally. You could have visible better sun panels -- on emergency street indicators or name containers, on buoys, even in parking plenty to energy lighting fixtures. Although those better panels are not as ordinary as sun powered calculators, they are in the market, and no longer that rough to identify if you recognize in which to appear. There are sun mobile arrays on satellites, in which they're used to energy the electric strategies. You have most likely additionally been listening to approximately the sun revolution for the final twenty years -- the inspiration that sooner or later we can all use loose electrical power from the solar. This is a seductive promise: On a brilliant, sunny day, the solar shines roughly a million,000 watts of vigour in step with rectangular meter of the planet's floor, and if we might accumulate all of that vigour we might simply energy our houses and places of work free of charge.
Q:What things can a solar panel power?
What things can moving water power? It just depends on the size and number of panels.
Q:all i want to do is provide enough electricity for 2 fluorescent bulbs i was looking at some 80 watt panels how many of those would i need and what else do i need for storing the electricity for use at nite? and how much would it all cost?
The solar panels are made in China because there are fewer environmental regulations and cheap coal power. It takes a lot of energy to melt silicon and there are toxic waste products. It would be three to five times more expensive to make the panels in the US ( three times is just for reprocessing the toxic wastes ). Solar cell made in China are about $2 a watt, perhaps as low as $ a watt but in truth the claims for $ a watt or less solar panels as in thin film solar panels have much lower efficiency and require perhaps ten times more surface area.
