Your Share of the Sun - what is important to know?
Available solar energy at your home is based on these primary factors:
Solar energy is not evenly distributed over the surface of the earth, and your geographical location – specifically latitude - is an important factor.
- Orientation to Sun
When roof or wall segments of your home face towards the sun, it is more likely your home is solar "friendly".
Ideal slope or angle for the area where the solar panels will be placed depends on location and local climate. Together these factors determine whether a steeper or gentler slope increases the potential for solar energy gain.
Shadows created on solar panels by surrounding trees, buildings, and hills reduce the amount of solar energy available.
Now, let's calculate how location, orientation, roof slope and shading impact your share of the sun.
