Orientation of your home is an important factor and needs consideration before the installation of solar panels. For the purpose of collecting maximum energy from the sun, install solar panels where they face south direction. It is the possibility that your roof does not have a southern sunlight exposure due to some obstruction like trees or other homes. In this case, we may consider a ground mounted solar panels instead of the roof mounted solar panels.
Plan proper angle of the solar panels if the orientation of your home gives sunlight exposure from the south. The pitch of your roof also helps deciding the installing angle of solar panels. The best angle, to install solar panels, is an inclination of 40 degrees plus or minus 15% in the south direction. Steeper roof is not appropriate to get maximum sunlight, in this case ground mounted solar panels can work. If the roof of your home is not that steep, roof-mounted solar panels can be arranged to receive maximum sun exposure.
The size of solar panels for homes depends on your roof construction and effective areas. Load ratings of your roof and ideal available space for solar panel installations are two important factors which require consideration for the safe and effective solar panel installation. Ground mounted solar panels have a large capacity of 20 kilowatts as compared to the roof mounted solar panels, which have size range of 3 to 10 kilowatts. It depends on your required capacity to what type of solar panels systems would be appropriate for you - ground mounted or roof mounted.
