The solar cell coverts the sun light into energy/electricity
Any renewable energy can provided it had enough of such renewable energy and the need of energy for such building. For a building require 200 kWh of electricity per day then if you could install 400 m2 of solar cell to support the building. It is more the matter of sizing to support but limitation would be in term of economic. How much 400 m2 of solar panel would cost over 400 m2 of land.
You can use solar energy to power your house. You will need to get solar panels to convert solar energy to usable energy.
Phones with solar would mean that the price of the phone would go up. And phones don't need solar panels because they don't pollute. Also, calculators need a very small charge to run, easily provided by a small solar cell. Cell phones need much more energy than that to power their calls.
You look at the job you need to do, ie, how many volts and amps, or volts and watts, that you need. Then you look in the catalogs for a solar cell or solar cell array to produce that much power.
1. solar energy you get from the sun while wind energy you get from the wind 2. solar energy you have to have solar things (ex solar ovens) wind energy you need a windmill for.
The answer to your question really depends on what you are using the energy for. For example, if you're using solar energy to grow crops then obviously not! If you're trying to harness solar energy for use in, say a home? Then the solar energy will need to be put through a Photo-voltaic cell (Solar panel) and then the electrons that are knocked out of the silicon wafers within the solar panels will travel through wires and then generally into a battery. In some cases the battery is bypassed (ie. a Solar Calculator). One can also have "Passive Solar Collection" which avoids a solar cell at all and is commonly used to heat water at cottages or campsites. Basically a hollow object (pipe usually) is filled with water and painted black. The thermal energy from the sun dissipates into the (generally conductive) object and finally into the water within. Hope this helps!
This has been discussed since the 1970s or earlier, but will need widespread popular support to become a reality. Wind and Geothermal energy are also possibilities.
No, biomass typically produces energy through incineration which does not require solar energy.
we need solar power because it will save us lots of energy
Once you convert the solar energy to electrical energy, it makes no difference where it came from. You do need to consider that solar energy is not available 24 hours a day.
Solar energy converted in to chemical energy by photosynthesis
In order to produce electricity, a solar cell needs sunlight and an electrical circuit.
