Q:i need someone to advice me which solar panels to buy.i have looked into few companies and i need some more info before decidingthe companies i checked were Sun tech trina solar Canadian solar and LDK solar.whice company should i pick?? please help.
Are you talking about buying panels, or investing in stock? LDK does not make panels, they make solar grade silicon that goes into panels. I haven't heard bad buzz recently about any brand of panel. Therefore, I would go by price per watt alone. If you type in solar panel price into Google, you're sure to get directed to the major sellers, each of whom will sell many brands of panels. There are a couple other requirements that I would have for a serious system: ) Safety certification such as UL. This will be legally required for a grid-tied system. All panels except the really fly-by-night brands and factory seconds have this. 2) 25-year performance warranty. It's standard now for a manufacturer to guarantee that their panel will still produce 80% of the rated output after 25 years. Older panels may say 20 years. Junk panels will have no such warranty, or something ridiculous like 90 days or year. 3) Crystalline silicon. Monocrystalline or polycrystalline doesn't matter. Every few years, someone claims that they have an amorphous or thin-film technology that's durable. Being conservative, I'm still waiting for such things to be proven. Some crystalline panels have been in service since the 70's, although they are pitifully weak by today's standards. I've heard good things about the Sanyo HIT hybrid panels, but that's only from one person who had them installed.
Q:How long does it take to recoup the investment in solar panels?
The time it takes to recoup the investment in solar panels varies depending on several factors such as the cost of the panels, installation expenses, local energy rates, and available incentives. On average, it typically takes around 6 to 10 years to recoup the initial investment. However, with decreasing panel costs and increasing energy savings, the payback period is continually improving, making solar panels a worthwhile long-term investment for many homeowners and businesses.
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:Solar panels single crystal and double crystal in the rain which is easy to use
From the cost of production, than the monocrystalline silicon solar cells to be cheaper, easy to manufacture materials, saving power consumption, the total cost of production is low, so get a lot of development. In addition, the polysilicon solar cell life than monocrystalline silicon solar cells shorter. From the performance and price ratio, monocrystalline silicon solar cells also slightly better.
Q:I want to get definate instructions on how to make the components and convert my home to solar energy. I know I could hire some one to do this, but frankly I do not have the funds at my disposal to do it. I thought if I could find detailed instuctions I could slowly do it myself (with my husband's help). I have looked into loans for this purpose to no avail. Finding the information on the net could take forever! If anyone knows a site that would give me the information or even a hint on how to start? Any help will be appreciated, but if you have any good links to good information please share them with me..Thanks
I doubt that you are going to want to learn how to dope your own silicon wafers, add contacts and laminate them into PV panels.? I also doubt that you're going to even want the various chemicals to make e.g. cadmium-based cells anywhere near your house (cadmium is a very toxic metal).? In other words, making your own solar panels is not an at-home project. You can buy solar panels based on cells of several different types.? A link to a Pricewatch-like website for current prices on solar panels is below.? Mounting panels to roofs or pole mounts, running conduit and wires, and installing battery banks and inverters are within the capabilities of skilled laypeople. More data at the links. Edit:? I am reporting all of Agua-Luna's cut-and-paste pieces as spam.? I encourage others to do likewise.
Q:Can solar panels be used for air conditioning?
Yes, solar panels can be used for air conditioning. By converting sunlight into electricity, solar panels can power air conditioning units, reducing reliance on the grid and providing a renewable energy solution for cooling purposes. However, the efficiency and capacity of solar panels may vary depending on factors such as the size of the system, available sunlight, and the energy demands of the air conditioning unit.
Q:Can solar panels be installed on billboards?
Yes, solar panels can be installed on billboards. In fact, it is becoming increasingly common to see billboards equipped with solar panels to harness solar energy and power their lighting systems. This not only reduces the environmental impact of billboard advertising but also helps in promoting renewable energy usage.
Q:How much solar energy does a 2m by a 3m solar panel convert to energy on a sunny day? Assume that the solar cells are 30% efficient.I'm not looking for the answer so much as I need an explanation o how to solve this type of problem... Thanks!!
You have the area of the solar panel. You know their efficiency. What you need to know now is the energy (per area) delivered by the sun. The energy delivered by the sun can be found on the internet. Earth ,43 – ,32 W/m? (wikipedia) That is offcourse for your solar panels perpendicular to the ray's of the sun. If they are under an angle you should see what the area of the projecton of your solar panel is on a plane perpendicular to the ray's of the sun. So know you have the intensity W/m? and an area (or effective area). Here you go the energy deliverd by the sun. And 30% of it is what you get out of your panels.
Q:Can solar panels be installed on hiking trails or nature reserves?
Yes, solar panels can be installed on hiking trails or nature reserves. However, certain considerations should be taken into account to minimize the environmental impact and ensure compatibility with the natural surroundings. Careful planning, appropriate technology, and consultation with relevant authorities are necessary to strike a balance between renewable energy generation and preservation of the ecosystem in these sensitive areas.
Q:Is it good? ( solar energy)
It depends mainly on where you live - both politically and geographically. It's very worthwhile if you live in the Southern hemisphere and your house faces north. The same holds true if you live in the Northern hemisphere in a south-facing dwelling. If your government gives a generous rebate towards your purchase of the panels (as the Australian one does) then ,yes, it is worthwhile as you can make your money back in only a few years. Of course if your motivation is more an ecologic than economic one then go ahead and do it.
