How much energy does a 200 watt solar panel make in one day?

Answer 1

Solar energy is free. It costs money to build an installation to harvest this energy. So there is no straight forward answer to this question since it depends on the cost of the installation and the energy that is being replaced (electrical, heat etc.).

Answer 2

Solar farms come in different sizes so they produce different amounts of energy based on their size. It takes about 32 acres to make enough electricity to produce one gigawatt-hour per year, enough to supply power to 1000 homes.

Answer 3

Assuming you mean the photovoltaic solar panels (those that produce electricity): A solar panel doesn't store electrical energy. All energy must be used immediately, either by selling it to the electricity company (as you can in some places), or by storing it. If you want to store it, you need a battery (a normal car battery will do), and electronic devices that control the charging (mainly to keep the car battery from over-charging).

A typical 75 watt solar panel will provide about 150 watts of power over a typical day.

Answer 4

You can multiply the 200 watts (or 0.2 kW) by the number of hours the Sun shines. Result is in kWh. However, it will work at maximum efficiency only when the Sun is at the highest position (since the panel won't usually turn around to follow the sunlight). Also, part of the energy will be wasted when storing the energy in a battery.

Answer 5

This depends on many factors - the rating of the solar panel (some produce more than others), the location (some places receive more solar hours than others), the direction of the solar panel (in the Northern Hemisphere, South-facing tilted basically at the same degree as the latitude is optimum), etc.

So, there's no quick, easy answer to this question.

However, to give you a general answer - the typical solar panel installed on homes and businesses is rated at about 200 Watts. A typical panel installed at optimum direction and angle in LA will produce about 290 kWh/year. The same panel at optimum direction and angle in NYC will produce about 240 kWh/year.

Answer 6

That will depend on the size of the panel, how many panels you have. and how much sunlight and the number of hours daylight.

Answer 7

It depends on several factors.

Answer 8

None.

They don't use any energy. They generate energy. There are too many sizes and different types to tell the amount of energy they generate.

Answer 9

0.43 kg per kwh
