The amount of energy your solar panel will produce is rated by watts. For example, if your solar panel is rated 100 watts, then on a clear day, your solar panel will produce 100 watts per hour. To find out how much electricity you need to produce, look at your electric bill and divide the total by 30 days and then divide it by 3 as there is generally bright sunlight one third of the day.
If you reside in an area where temperatures drop to freezing, you have to take special care of your solar energy system. Every time the weather gets very cold, you need to turn the system off and drain it. This will help you keep your system working for a much longer time.
If you cannot afford to buy solar panels or do not want to make a long-term investment, you should consider leasing a solar energy system. Leasing a system saves you money, and you can usually recoup the installation costs within a matter of weeks.
