Q:when building a solar panel should the diode be on the positive or negative sidelittle more detail i just built a solar panel and im running it to a grid tie converter should i put diodes in if i add another panel or are they only for battery systems?
the blocking diode goes on the positive side
Q:Is it really necessary to make solar panels that expensive?
it cost less then $000. to make a car if you add all the cost of the material the average car made in the USA is sold for 30,000. before the company make a profit they need to sell 6 cars to pay for the labor. With a solar panel system it cost depending on you kilowatt use then they figure out the life expectancy of the unit what your monthly ele bill would be and that is what it cost for your system and that is with out the carrier charge from your power company who charge you for both when you use or sell power to the grid and most of the systems sold are sold to tie into the grid. as far as how much does it cost to make a solar panel The reason they give the price per watt is that is how they charge to sell them The process is not as complicated as they make it The high cost is in the so called shortage in silicon they claim there is a shortage of the type of silicon used in making the chips but last I heard silicon is just sand and it is the eight most common element on the planet it is the same process used to make computer chips which you can by now for around a dozen for a penny put that does chips togethet and you have one of the around 00 chips in a solar panel so a solar panel costcost about fifty bucks to make solar panel 00 watt sells for around $50. for a starter kit they sell them 200 percent mark up minimum the big cost is in the installation .
Q:Dose a solar panel need the entire range or spectrum of sunlight to produce power?
It's a huge field of study, very important to solar cell development. People are trying to optimize spectral response for sunlight, even for sunlight in specific places. Google solar cell spectral response for many many websites. Most of them are specific to one experiment.
Q:Any recommendations for companies? Any things to look out for?
It strongly depends on where you live. In California or Hawaii, for example, solar can be cheaper than the power company, even without subsidies. Any incentives you get just make it better. Whatever you do, like any construction project, get 3 bids from different companies. If there are not 3 companies in your area, you are probably in a poor location for solar. Avoid any company that does a hard sell and tries to get you to commit immediately, or makes you uncomfortable in any way.
Q:wondering if i should get them?? not sure if its worth leasing? also anyone know anything about solar city?
Current commercially available photovotaic panels are about 5% efficient. The current record in the laboratory is 42.8%. There are designs expected to achieve 65% on the drawing board. It's like investing in low interest rate bonds. If you just wait a couple of years and then invest, you will make more money simply because you would then have higher interest rates. Likewise with solar panels, if you just wait a few years then because they will be so much more efficient, you'll get a better return over the life of the panels.
Q:solar panels!!they are fantastic! cause they are the new way of quot;chargingyour home, without killing the earth!would you install them, or not? and make sure you say WHY
Check with the planning and zoning department of your city. They can refer you to the proper citation in the land development code in Plano. Also check to see if the neighborhood or district where you live and/or work has any restrictions related to solar panels. Arizona just made it illegal for an homeowners association to prevent a homeowner from installing solar panels.
Q:I am curious about how much of the energy that a solar panel of a given size and capacity will produce in it's lifetime, and what fraction of that energy was required to produce it in the first place?
Best way to determine that is to find the retail cost of a solar panel and compare it to the retail cost of oil. Assuming similar profit margins a $300 solar panel costs the same to produce as 00 gallons of oil.
Q:Do solar panels require a battery backup system?
No, solar panels do not necessarily require a battery backup system. Solar panels generate electricity from sunlight, but without a battery backup, the excess energy produced during the day is typically fed back into the grid. However, a battery backup system can be useful in areas with frequent power outages or for those who want to store and use the solar energy generated during the night or when the grid is down.
Q:I am interested in installing a home solar panel system. In my city, we get a little over 5 hours of sun, and I typically use about 800-900 kwh per month.The available roof space is small- approximately 600 sqft.The online calculators provided on various sites are not uniform, thus providing inconsistent responses with the same input data.I think I need a 5kw system approximately. Can anyone verify that and provide a link for a reasonably priced system to meet my needs? Prefer grid-tied, but off-grid is acceptable as well.Thanks!
I'm sure that you will discover everything related solar energy at www.okorder .
Q:hi so im doing a school project thing and they have a lot of different questions for us that help us decide whether we would rather a city have a nuclear reactor, or solar panel. But i cant seem to get the last 2 questions...help please???so question ........What types of emissions, if any, are produced by each type of generating station? Do these emissions affect human health?question 2.....What are the long term financial costs associated with maintaining each type of generating station?thanks!
: Mostly produce heat 2: Keep Clean, trim branches, over hanging shrubs, and things like that.
