If it came out directly as AC then there would be no need for an inverter and then you could be off the grid without batteries or a generator, right? Am I missing something? Or is it difficult to turn it to AC instead of DC?Are you a person who is interested in green energy and using Solar Energy Panels or creating your own Home Wind Power, then you are just like myself. I have had a keen interest in green energy every since I studied Architecture many many years ago. At that time I learned that is was possible to build homes that are completely self sufficient which was so compelling to me I had to know more.

The electrical current generated by the cells is DC and there is nothing that you can do about it except to attach an inverter if you want AC

Maybe this will help explain it:

I need to power a refridgerator, and some smaller items. I don’t plan to operate
an AC unit.

Any commercial-grade solar panel will do the trick. The bigger question is how much you need, and whether you need storage.

If you plan to go off-the-grid, you will need to design a large enough system to provide both for normal use and sufficient storage to carry you through periods of no sun – and overnight, of course.

The rule-of-thumb is approximately 3 x your peak load, with sufficient storage for a full 24 hours of no sun.

Assume your refrigerator uses an average of 800 watts per hour and operates for 8 hours per day (probably a bit high in both cases, but better to be cautious). Assume your total additional average load is also 800 watts – meaning _NO_ hair dryer, flat-screen television, heavy-duty vacuum cleaner, electric heater, clothes washer, dishwasher, electric stove, and so forth.

You will need a 5,000 watt system with 30,000 "watts" of storage. That is a pretty large bank of batteries as you might imagine.

Your approximate installed-cost will be something on the order of $40,000 – $60,000, or $8 – $12/watt depending on a lot of factors.

What percentage of the rated power? Panels would go in the northeast. I mean just in general I know that panels are generally about 11-19% efficient but of the rated power what should I actually get on average given average conditions? If I had a 200W panel would I get 100W? 50W? 150W? Thx in advance.

Panels are rated at a standard test condition (STC). The rated output has nothing to do with efficiency. A more efficient panel is physically smaller than a less efficient panel, a 200W panel outputs 200W at the STC, regardless of its efficiency. You’ll generally pay more for a more efficient panel, so if space isn’t an issue, you may be better off getting a less efficient panel, you’ll get the same output, but it will take up more space.Are you a person who is interested in green energy and using Solar Energy Panels or creating your own Home Wind Power, then you are just like myself.

i been close link with spinning mills.is there any chance to lay solar voltranic cells on the roof, from there producing power.what is the constraint behind this idea?and the possible power like how much we can produce from this.

In today’s world with huge advancement in science and technology it is easily possible to achieve the your desired target. You can use solar cell on your roof top which can produce electricity which you can use to fulfill your desired need and requirement.Since the equipment involved is not of much bigger size and dimension, therefore you can easily install them and use it for your requisite purposes.

I’m curious to know how many panels I would need to maintain a rudimentary amount of power in the event of an outage or crisis. Imagining the price to be high, I don’t know how big of a system I could get, so I’m curious if I wanted just enough panels to power a refrigerator and stove and maybe an a/c. Just those three basic necessities.

i think the beginig is expensive but it pays for itself in a short amount of time.
alot of my friends installed it recently with th e company below- you can probly ask them your questions! good luck!

We see increasing, what appear to be, solar panels on electric poles?

Here is an article about this.

They use the poles (which they already have) and install power panels, the electricity is given into the grid.

There are companies in NJ which use google earth to find buildings with large roof tops (imagine all the warehouses !), contact them and lease the rooftops to install solar panels, there a different ways how to finance that (by them, by the company, ….) and they sell the electricity into the grid and receive a certain price for this. Usually the refinancing is 5 – 7 years of the investment, after this is profit for additional 15 – 20 years.

Walmart had a project to put solar panels on the super centers ….
