How much power is generated with solar panels?

Question

how much power is generated with solar panels? also please give me links for that information.

and how much would the costs be for this alternative energy source?

Answer 1

If you put 'solar world statistics' into a search engine, you will discover that there are many statistics that are being heavily contested.

Picking up the truth from among hype is the task.

Solar panels typically have a rated maximum output of about 110 watts per sq metre.

But actual delivery  to grids of kWh  would point to a number closer to 14 watts / sq M. on a 24 hour basis.

Grid management is thus cautious about yield claims when history points to only 1/8 of rated maximum output.

There may be some inappropriate expectations, when a solar roof is first powering the building, and only selling excess to the grid.

Answer 2

A solar panel is a photovoltaic module that consists of multiple PV solar cells assembled together for practical and useful purposes. The panels are typically flat, and are available in various heights and widths. Here is some basic information about solar panels.

    * In the panel, the cells are connected in a series to derive higher voltages (in Volts). For example, if a single solar cell produces a voltage of 0.5V, a panel needs at least 24 cells, connected in series, to generate 12V.

    * Usually a panel has more cells (for example 28-40 cells) to compensate for voltage drops or for charging batteries.

    * The current generated by the panel (in amperes) is larger when the individual solar cell has larger surface area.

    * If needed, connecting solar cells in parallel will also provide more current.
