Panel Selection: Determine what solar panel best fits your needs and your budget.

  1. The energy calculator will provide you with the system size that will achieve your desired energy offset.
  2. Select your solar panel and the calculator will indicate how many of those panels you will need to reach your optimal system size. (See panel comparison chart below).
  3. Develop a layout to determine how to best to fit the panels on your roof. South facing roof space is best, but both east and west facing roof space can be usually be utilized with less than a 20% reduction in efficiency for those panels.
  4. Another consideration that is important to some, but not to others is the aesthetics of the panel. The black on black panels can blend into some roofs more easily that a panel with a light background, but the cost per watt is higher. In the end, this is a personal choice.
