1. Buy (or make) yourself a small solar panel. For about $100 you should be able to get one rated at 12 volts or better (look for 16 volts) at an RV or marine supplies store or from Greenbatteries Store or Earthtech.
2. Buy yourself a battery. We recommend rechargeable batteries from these green companies: Greenbatteries Store and Batteries.com. Get any size deep cycle 12 volt lead/acid or gel battery. You need the deep cycle battery for continuous use. The kind in your car is a cranking battery--just for starting an engine. Look for bargains, the cheapest ones should cost about $50-60.
2.给自己买电池。我建议从如下绿色公司购买可充电电池：Greenbatteries Store and Batteries.com.购买任意尺寸的12伏铅/酸或凝胶深放电电瓶（这里补充说一下一般电瓶有两种：启动电瓶（STARTER BATTERY）和深放电电瓶（DEEP CYCLE BATTERY），两种电瓶的区别在于单位时间放电量上有所不同。）。你需要不断使用深放电电瓶。在你汽车里的电池是起动蓄电池，只用于启动发动机。寻找特价品，最便宜的约50～60美元。
3. Get a battery box to put it in for $10. (This is good for covering up the exposed terminals in case there are children about If you going to install the system in a pump shed, cabin, or boat, skip this.) Buy a 12 volt DC meter. Radio Shack has them for about $25。
4. Buy a DC input. I like the triple inlet model which you can find at a car parts store in the cigarette lighter parts section for about $10. This is enough to power DC appliances, and there are many commercially available, like fans, one-pint water boilers, lights, hair dryers, baby bottle warmers, and vacuum cleaners. Many cassette players, answering machines, and other electrical appliances are DC already and with the right cable will run straight off the box.
4.买一个直流输入模块。我喜欢3个点的输入模块，你可以在一个汽车配件商店香烟打火机区买到，大概10美元。这足够满足直流设备的功率，而且有许多商业应用，如电风扇，one-pint water boilers，电灯，吹风机，热奶器和吸尘器。许多录音机，答录机是直流设备，只要配上合适的电线就可以运行。
5. But if you want to run AC appliances, you will have to invest in an inverter. This will convert the stored DC power in the battery into AC power for most of your household appliances. I bought a 115 volt 140 watt inverter made by Power-to-Go at Pep Boys for $50. Count up the number of watts you'll be using (e.g., a small color television(=60 watts) with a VCR(=22 watts), you'll need 82 watts. Cheap inverters of many sizes can be had online from Lanes.
5.但是，如果你想运行交流电器，你须要买一个逆变器。逆变器将存在电池里的直流电变成交流电供家里应用。我在Pep Boys上花了50美元买了一个115V、140W的逆变器（made by Power-to-Go）算一下你需要用的瓦数，比如，一个小电视机=60W，录像机=22W，你需要82W，Lanes网上有许多便宜的各种尺寸的逆变器可以买到。
6. Use a drill to attach the meter and DC input to the top of the box.
6.用钻子将直流电表和输入模块装在盒子的最上面。
7. Use insulated wire to attach the meter to the wingnut terminals on the battery. Connect the negative (-) pole first. Only handle one wire at a time. Connect the DC inlet to the battery in the same way. Connect the solar panel to the battery in the same way.
8. Close the lid (I use a bungee cord to keep it tight). Put the solar panel in the sun. It takes 5-8 hours to charge a dead battery; 1-3 hours to top off a weak one. It will run radios, fans, and small wattage lights all night, or give you about 5 hours of continuous use at 115 volt AC, or about an hour boiling water. This system may be added on to with larger panels, inverters, and batteries.
Options: A pop-up circuit breaker may be added between the positive terminal and the volt meter. Some of you will want an ampmeter as well. The panels I recommend have built-in bypass diodes, but I recommend charge controllers for people who have panels without diodes. Another option is a voltage regulator, which is not necessary for a system this small, but a larger system would require one.
