Can I make a profitable enterprise just by gathering solar power (photovoltaic cells) and selling it?

Provided I have the land (in Greece) and the capital.
Provided I have the land (in Greece) and the capital.
I'm thinking large scale here, like 5+ km2.

No, because solar power by photovoltaic cells is expensive to produce, is an unstable source (limited to day time, and not too cloudy), and storage is rather expensive.
it is marginally profitable when intended for self use, because the...

Photovoltaic cells & solar power plants?

Can someone send me links to reliable, scientific websites
that explain how the energy generated from photovoltaic cells
and solar power plants are sent to people to use?

Thank you in advance!

If they are central plants feeding general users, there is no difference between solar steam generation or photovoltaic and any other power generation. It is converted to AC and added to the power grid.
If it is a local operation, then...

In a sunny location, sunlight has a power density of about 1 kW/m^2. Photovoltaic solar cells can convert this?

In a sunny location, sunlight has a power density of about 1 kW/m^2. Photovoltaic solar cells can convert this power into electricity with 14% efficiency. If a typical home uses 380 kWh of electricity per month, how many square meters of solar...

Let's say you have 1 square meter of panels. Then you get 8 hours x 1 kW/m^2 x .14 = 1.12 kWh of energy per day.

If you have 2 square meters, you get 2.24 kWh's per day.

If you have N square meters, it's 1.12N kWh's per

Photovoltaic cells generate DC at a fixed voltage (determined by the materials the photo-cell is made from). The voltage does not depend on the amount of light.

The current available does depend on the amount of light. So you want...

SANYO HIT(R) Solar Modules to Become "Panasonic HIT(R)"

TORONTO, ONTARIO, Dec 12, 2011 (MARKETWIRE via COMTEX) -- SANYO Canada Inc. (SANYO), a subsidiary of SANYO Electric Co., Ltd., announces that as of April 1, 2012, the branding of its HIT(R)(1) solar modules, will change from "SANYO" to "Panasonic." SANYO's solar modules are recognized in Canada for their power-generated-per-square-foot performance.

Unifying the solar brand is part of a wider scheme of consolidation of brands of certain products currently being carried out by the Panasonic Group in order to take advantage of the strengths of each company within the group. Combining SANYO's solar technical capabilities with Panasonic's wide global network will allow further synergy to be generated within the group and strengthen the solar business globally.

What are multijunction photovoltaic cells?

by admin

Multijunction photovoltaic cells are a sub-class of solar cell or photovoltaic cell developed for higher efficiency. These multijunction cells consist of multiple thin films produced using molecular beam epitaxy and / or Metalorganic vapour phase epitaxy. Each type of semiconductor will have a characteristic band gap energy which, loosely speaking, causes it to absorb light most efficiently at a certain color, or more precisely, to absorb electromagnetic radiation over a portion of the spectrum. The semiconductors are carefully chosen to absorb nearly all of the solar spectrum, thus generating electricity from as much of the solar energy as possible.

In short, in the multijunction structure, several layers each capture part of the sunlight passing through the cell. These layers allow the cell to capture more of the solar spectrum and convert it into electricity [1].
