        Many do-it-yourself homeowners are interested in
    trying out solar power to learn about the technology
    and perhaps to provide energy for limited-use applications.
    There are a variety of ways to find cheap solar panels
    (板), including buying used and building your own with
    factory seconds. Both methods will save money while
    forcing you to learn the ins-and-outs of a solar power
    array (阵列). 
        We've all seen solar-powered street signs or PV
    panels being used for various purposes at remote
    locations. When those units become cracked or chipped
    and- are considered "unsafe", companies are forced to
    replace them, generally to avoid responsibility issues.
    Because it's difficult to get rid of PV panels, many
    companies, if approached, are willing to give them away or to sell them for modest prices. Depending on the
    degree of damage present, expect to see performance degradation (降级) in the range of 10% to 60%. A
    multimeter (万用表) can be used to test the panel before buying. If the panel's free, take it anyway. It could
    still be useful in a home solar project.
         A solar panel is really nothing but a box serving as a container for a large group of solar cells. Factory
    second solar cells are usually sold on eBay at a small part of their regular cost. The cells come in a variety of
    sizes. You will need to figure out how much power a single cell produces to determine how many will need to
    be wired together to form an array.
         A simple search of the Internet will show numerous sites detailing home solar panel projects. Do-it-yourself
    lovers are generally quite generous in supply photographs of their work and description of what went wrong
    and right with the project.
         Getting cheap solar panels with slight imperfections either used or through sales of factory seconds, is a
    perfect solution for home-built renewable energy projects. The high number of solar lovers online provide a
    wealth of useful information. Only limited skills are required, plus an understanding of the basic wiring involved.
    All are well within the talents of almost any home handyman. Beyond the satisfaction of having completed the
    project, you'll come away with a functional solar panel that will be a source of power for use around the house
    or at remote locations.
         Solar energy systems are quickly becoming more popular with homeowners as prices continue to decline.
