    California Solar Heat Map

    Posted September 28, 2007

    According to the California Energy Commission, solar energy,
    in particular photovoltaic produced power has grown
    massively in recent years. Prior to 2002, only 1,675 grid connected photovoltaic installations
    were registered with the commission. Fast forward to 2008, and there are 29,628 installations recorded.
    That’s a 17x increase in just 6 years! In just the last 3 years, total installations have
    more than doubled, with 14,058 installs in 2005.

    Looking at the average system size over the years, one can tell that early adopters of solar were most likely
    corporate establishments (with a larger system requirement). As solar power became a more viable option for the
    average homeowner, the system size lowered and the number of systems increased. The amount of carbon emissions saved
    by solar systems is incredible. By the end of 2007, these systems have saved over 533 kilotons of carbon emissions
    from going into our atmosphere.

    Inspired by these statistics, we at were curious as to
    where this explosive growth in solar panel installations occurred within California. Rather than reading over
    data and spreadsheets, we thought it would be interesting to create an interactive heat map that depicts
    the concentration of solar installations (number of systems, total watts, average system size, and carbon emissions)
    in California and the progress solar has made over the last decade. Feel free to scroll through the years to see how
    the numbers change from year to year. It’s fun and educational!

    Did you know?

    The average homeowner saves over $1000 a year on electricity by installing solar panels on their roof. That’s including the cost of solar panels. The most
    common way to go solar today is by leasing, which essentially means instead of paying the utility you pay less to produce your own energy.
