To determine the energy needs of your home or business, you should evaluate your past energy usage and future needs. You can use online calculators or consult with an energy professional to estimate the size and number of solar panels needed to provide enough power. There are different types of solar panels, including monocrystalline, polycrystalline, and thin-film, and the right type depends on your location and specific energy needs. The cost of installation and maintenance can vary based on factors such as location, panel type, and system size. There may be incentives and tax credits available for installing solar panels in specific locations, such as federal tax credits or state-specific programs. More information at
