    Our home solar panels are the best price/performance system available for residential, farm, and business solar electric. If you have the rooftop space and appropriate site for a system, it is the best system you can buy. Talk to RoofMill.net for a review before you buy anything else to find out why this RoofMill™ Hybrid is such a superior product to anything else out there in the market.
    How the solar panels are made? Well solar cells can be classified into first, second and third generation cells. The first generation home solar cells, wafer-based cells are made of crystalline silicon, the commercially predominant PV technology, that includes materials such as polysilicon and monocrystalline silicon.

    What is a home solar panel module? Well, the term “home solar panel” refers to a panel designed to absorb the sun’s rays on the roof of a home as a source of energy for generating home electricity or heating. A photovoltaic (PV) module is a packaged, connect assembly of typically 60 or 72 solar cells. How does a home solar panel cell work? When a home solar panel cell is hit with light energy, electrons are knocked loose from the atoms in the semiconductor material. The home solar panels have electrical conductors carefully attached to the positive and negative sides, this creates an electrical circuit in the home solar panel, the electrons can be captured in the form of solar electricity and sent to the home.

    How does a photovoltaic cell work? A home solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of home electricity. Home solar panels actually comprise many solar panel photovoltaic cells. Photovoltaic means they convert your homes sunlight into electricity.

    Are you searching for a home solar system kit, best solar panels for home use, solar providers near me, solar panels for your home cost, free solar panels for home use, solar system for home in india price, or how many solar panels to power a house? Contact us.

    What is the use of home solar panels? Your home soloar panels can be used to generate a portion of your home, farm, or business electrical power in order to reduce your homes dependency on traditional power sources. You can install home solar panels to provide electricity just for appliances or lighting, to reduce your dependency on the utility company, as well as lower your residential bill. What is the solar panel for homes? Solar panels for homes are devices that convert light into residential electricity. They are called “solar” panels because most of the time, the most powerful source of light available is the Sun, called Sol by astronomers. Scientists call them photovoltaics.

    copyright all rights reserved How to make a parabolic shape from a flat sheet, I discovered that by attaching corners of screen, covering with 50/50 cement, screened sand mix, instead of water, Elmer’s glue, then cover with plastic, weighing it down with sand forms a parabolic shape from the flat sheet of screen when it hardens. I cover with tin foil, attach 4 corners of sheet, then covering with plastic, weighing it down with sand forms a parabolic shape from the flat sheet of tin foil, seal rest of foil , add valve and suck the air out creating the most powerful solar energy lenses ever seen!

    First you make cheap solar lenses…the basic idea…
    first idea…

    Then you use lenses to light Plasma of a short wave light.
    The problem with solar electric is Sun light is mostly Heat, only a small percentage of Sun Light is Ultraviolet(Short wave) that photovoltaic cells make electricity from.
    Like a Neon tube that makes white light, that uses a electricity to light plasma, my idea is use light from a focus of many lenses(heat) to light the short wave tube(like tanning bulb, that make mostly Ultraviolet & Short wave) and the light goes to a small cheap photovoltaic panel(By doing this I am changing almost all heat energy of Sun to Short Wave, this is what photovoltaic panel use to make electricity). I expect to go from what we get now 5% efficiently to 50% efficiently.

    So this will make electricity cheap for running air conditioners and refrigerators.

    Second idea..on lenses…

    All that is needed is large, cheap, efficient lenses, this method of turning a flat sheet to a parabolic shape (efficient) and cheap method(cement screen) that can also make large lenses….
    the Video above…

    One problem left, I am using tinfoil that I solder and takes a lot of labor, if I used 100% reflective window tint I could use heat bonding and quickly manufacture!
