Many do-it-yourself homeowners are interested in
trying out solar power to leam 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.

阅读下面短文,并按照题目要求用英语回答问题。(请将答案写在答题卡上相应番号后的横线上)

Perhaps you are an average student with average intelligence. However, you can receive better grades if you want. Yes, even students with average intelligence can be top students without additional work. Here’s how:

1.Plan your time carefully. Make a list of your weekly tasks. Then make a schedule of your time. Be sure to set aside enough time to complete your normal reading and work assignments. Of course, studying shouldn’t occupy all of the free time on the schedule.

2.Make good use of your time in class. Listening to what the teacher says in class means less work later. Take notes to help you remember what the teacher says.

3.Skim before you read. Look over a passage quickly before you begin to read it more carefully. As you preview the material, you get some idea of the content and how it is organized. Later when you begin to read you will recognize less important material and you may skip some of these portions, Skimming(略读)helps double your reading speed and improve your comprehension as well.

4.      . Go over your notes as soon as you can after class. Review important points mentioned in class as well as points you remain confused. If you know what the teacher will discuss the next day, skim and read that material, too. If you review your notes and textbook regularly, the material will become more meaningful and you will remember it longer. Regular review leads to improved performance on tests.

5.Develop a good attitude towards tests. The purpose of a test is to show what you have learned about a subject. The world won’t end if you don’t pass a test, so don’t worry excessively(过分地)about a single test.

There are other techniques that might help you with your studying. Improving your studying habits will improve your grades.
