Before making a choice on how many solar panels you use make a list of all the electrical appliances you use and the wattage and hours utilized by each one. This will be helpful in determining how much solar power you will need. No matter if you decide to install the equipment yourself or have someone else do it, this information will help your choices. A good tip if you're thinking about using solar energy in your home is to consider leasing a system instead of paying for it out right.
