Aresidential pv system needs to supply 2kw. assume that: - the solar panel has an efficiency of 18% - solar irradiance on the surface of the solar panel is 1kw/m2 - 60-cell solar panel is used with and area of 1.66 m2. how many 60-cell panels will be needed to generate 2kw for the home?

To solve the problem it is necessary to find the total power generated by each of the panels and then through a proportional relationship find the number of total panels.

There is an efficiency of 18% of which the area of receives a surface radiation of

Therefore the power is subject to

Each panel will have the capacity to produce 0.2998kW

The number of panels required is determined by the total power given by each of the panels, that is

Therefore the number of panels required are 7

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !

luster is not a good characteristic to use by itself because luster is the property of minerals that indicates how much the surface of a mineral reflects light. the luster of a mineral is affected by the brilliance of the light used to observe the mineral surface.
