If you are planning on meeting with a consultant to install a solar panel system, you need to make sure you are prepared. Have a list of all electrical appliances along with their wattage and the number of hours you use them on hand. Any good consultant will need to know this information before a solar panel can be installed.

Make sure that any solar panels you put up are actually cost effective. While the installation cost can be dented with government assistance, you need to know how long it will take for energy savings to return your investment. Also factor in that you are not likely to get the same amount of power every single month.
Be prepared to keep your solar panels clean. The dirtier they get, the less efficient they are at generating power. While it is true that rain and wind can often take care of a lot of this for you, you do need to get up there sometimes and dust them off yourself.
