Don't think the biggest solar panel is the best. There are a lot of variables to consider when buying solar panels. You should consider each of these factors when making your decision.
One major advantage of solar power is that there are a wide range of systems on the market. While there are those that are very expensive, others are quite affordable. Therefore, regardless of your income level, you can afford to set up a solar power system. You just need to do your research and figure out what product is best for you.
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.
