Your Questions About Solar Panel Cost

Sharon asks…

Does anyone know how to build a solar panel with little or no cost?

I want to know before I purchase a home in the future. I am just sick and tired of being sick and tired of high energy bills. Also, I'm also interested of wind energy. Any answer would be appreciated.

Hello,
I just bought a solar power renewable energy ebook about a month ago.
I started to building my own solar panel to save on electric bill, I still need 2 more week to finish, and am very excite.
The ebook take you step by step.
I bought from this website: http://www.topreviewsite.net
good luck!!

Ruth asks…

How much do solar panels cost? how many would I need to power a 2100 sq/ft house, also?

Where can you by them? Are you able to install them in town or do you need a special permit or anything?
I already have energy star, the light bulbs, and good insalation

ssadmin answers:

Enough Solar Panels to go 100% solar in a house that size is incredibly expensive. I do not know the exact price, but I guarantee if you did some research you would not consider it. BUT if you connect yourself to the grid and let any surplus energy goto the city they are obliged to reimburse you, but only slightly, so you could get your money back. In a number of years, though.

Oh, and I highly doubt you need a permit. Just the know-how and the money.

David asks…

How much would a solar panel cost if it were 10 by 5cm?

I'm finding difficulty on getting an average price for a solar panel for a theoretical product which i've designed for an assignment. It is very small and I'd just like to know how much it would cost to manufacture a solar panel which is 10 by 5cm.
Does anyone have any idea, with evidence to back up your answers? Thanks, best answer gets 10 points

ssadmin answers:

That is very tiny. You will probably get a few tens of milliwats from it. You cannot benefit from economy of scale. For large panels you may get power at the rate of about $6/Watt.
This little flea-weight panel may cost $5 to produce, in quantities of thousands, but would likely retail for $10 – 20.

Daniel asks…

how much will be cost of solar panel?

If we opt to use solar panel as alternative of inverter which is generally use for source of power in case of power failure. If we choose to use solar panel what will be specification or capacity of panels to be used to use as source of power in case of power failure how much it may cost tentatively. And from where can I purchase solar panels.

ssadmin answers:

If you are running the inverter off a vehicle, you can simply clip the output of the panel(s) to your battery and use the same inverter that you would otherwise. Solar panels produce low voltage DC, and if you're using an inverter, it means your appliances need higher voltage AC.

First you define how much energy you need (watts of load x time needed) in watt hours. You then find out your local insolation (Google is your friend – insOlation with an “O”) to find how many hours of good sun you get – for India this number might be 6 or 7 hours/day on the average. You then divide your watt hours number by the insolation to get the wattage of panels that you need.

Make sure the output of the panels can charge your batteries – typically you'll get 12 or 24 volt panels. A 12 volt panel can be used without a charge controller to charge a 12 volt battery if you're careful and only leave it hooked up when the battery needs a charge, A 24 volt panel will need a charge controller to step the voltage down so you get good efficiency from the panel (it's called the maximum power point – Google it).

You'll also have to be careful not to discharge your battery too deeply at night. A good rule of thumb is to have battery capacity (in ampere-hours) of 20 times the current capacity of your panels. So if you need 1000 watt-hours/day, you'll need about 150 watts of panels. This is about 13 amps at 12 volts, or 260 AH of battery. That's two very large car batteries in parallel, or two T-105 golf cart batteries in series. Use your own numbers to see what you need.

Smaller panels (<100 watt) typically cost $3-4 US/watt. Large panels (200+ watts) can be gotten for as little as $1/watt in quantity. These are typically lower quality Chinese panels and they may be available locally. Look on the Web for dealers.

How much will be cost of solar panel / wind mill?

ssadmin answers:

Believe it or not, you can learn how to make a solar panel even If you’re not a technology geek or DIY expert.

If you’re in a hurry and looking for step-by-step instructions on how to build a solar panel,

It’s possible that with a little effort, even a newbie can make their own solar panel. You can build a solar panel easily and inexpensively using parts found on eBay, Amazon or a local hardware shop.

One of the main components when learning how to make a solar panel is the solar cells, which are usually made out of silicon (the same material used in computer chips). A solar cell is made of two layers of silicon, and is separated by a small piece of insulating material.

It takes all of these layers working together to convert sunlight into energy, thus creating solar power. I should also note that it doesn’t matter whether you go with Class A cells or Class B cells, as both will work nearly the same.
