Solar Pv Cells Transform Solar Light Into Electric Power In An Efficient Way

Today, because of the rising energy costs and electricity bills, most of the houses as well as commercial setups have solar PV modules. These are the modules that not only convert solar light into electric power, but also reduce the electric bills and keep the environment safe. Talking about the PV module deeply, it is a renewable energy system that uses photovoltaic modules on the roof of a building to convert solar energy or light into electricity. Later the electricity which generates through Solar PV is used to power various electronic appliances. One of the main advantages of installing solar PV is that the voltaic cell can also generate electric in the cloudy weather.

However, it is overcast, they are less effective. When it is slightly overcast, then the production of electricity may hamper or slowdown. For voltaic cells, light matters a lot instead of temperature. Talking about the photovoltaic cells they are made up of thin layers of semi-conducting materials including crystalline silicon that help in generating electric charge when exposed to light directly. Polycrystalline cells consist of two or more thin layers of semi-conducting and chemically treated silicon materials. Chemicals used in the cells react when light hits the cell and create an electric field across the layer; thus produce a direct current. The production of electricity depends on the intensity of the sunlight.

The electric power that generates through the solar PV modules is fed into an inverter that is used for electronic appliances. Direct current or DC that generate from PV cells is changed into alternating current or AC with the help of the inverter. Depending on the location and installation, solar PV modules can also be cleaned easily. Some of the modules are also self cleaning system when they are mounted at an angle of at least 15a. You should also keep in mind that these modules should not be installed in a heavily silted area including under the trees because dirt may reduce the power by up to 10% that these panels generate. When it comes to installation of these cells, you can get them installed with the help of experienced engineers.

Frequently Asked Questions

  1. QUESTION:
    Can PV solar cells also be used to collect heat?
    I know PhotoVoltaic (PV) cell voltage output drops with increasing temperature. The question is, could a photo cell cooling system attached to the back of the cells provide a usable heat supply for heating a pool, a residence or hot water for washing while helping keep the cell temperature down making them more efficient?

    • ANSWER:
      Your question made me curious ... looks like yes, and people are doing it already: http://solarwall.com/en/products/solarwall-pvt.php

  2. QUESTION:
    how do PV cells convert radiant energy into electricity.?
    im doing a science final and i need to know how PV cells convert radiant energy into electricity. thanks.

    • ANSWER:
      1. Photons in sunlight hit the solar panel and are absorbed by semiconducting materials, such as silicon.
      2. Electrons (negatively charged) are knocked loose from their atoms, allowing them to flow through the material to produce electricity. The complementary positive charges that are also created (like bubbles) are called holes and flow in the direction opposite of the electrons in a silicon solar panel.
      3. An array of solar panels converts solar energy into a usable amount of direct current (DC) electricity.

  3. QUESTION:
    Where can get information on Plastic sheet like materials that act as PV cells to convert light to energy?
    I want to install Solar PV cells to produce electircity for domestic use. I believe there is a new plastic material that converts light energy into electricity for domestice use This material can be used as sheet to cover the entire house roof to make use of the light that falls on the roof. Where can I get this type of light plastic PV material and what will will it cost
    Please advice Thank you

      Google is your friend. I don't think it would hold up long in most places.

  4. QUESTION:
    Is there a formula for the impact of high Temp. on PV cells?
    I live in Iraq
    air temp reaches to 50 C
    solar Temp reaches to 85 C in sun and 70 C in shadow

    how can I calculate the Impact of high Temp on PV Cells?

    • ANSWER:
      Every PV cell or panel has, or should have, a specification sheet. On it should be a maximum operating temperature. If that is above 85C then you are fine.

      One I looked up said:
      thermal cycling between –40 F and +185 F (–40°C
      and +85°C) at 85% relative humidity

  5. QUESTION:
    what are the best pv cells for resedential use?
    I would like to make my own solar panel one that could generate enough power to ease my electricity bills thanks in advance x

    • ANSWER:
      The equipment to make solar panels are quite expensive. Its not as easy as making a television or firearm or automobile.
