The belief is that the upfront investment will result in a savings for the homeowner in energy costs in the long term.
While the data is strong to have solar energy play a more prominent role in the overall energy sector in the United States, the prospects of other states initiating the same mandate as California is unlikely.  North Carolina is the number 2 solar market in the U.S. behind California and Steve Kalland, executive director of the North Carolina Clean Energy Technology Center at North Carolina State University, says “he doesn’t see his state adopting a similar mandate anytime soon. It is a pretty big stretch to imagine certainly any Southeastern state following suit in the near term, but the technology is getting cheaper and cheaper and the public is starting to clamor for it,” he said. “In North Carolina, the market is much more oriented toward larger scale solar farms.”
The WSJ article reports, “Wind and solar combined accounted for about 8% of U.S. power generation in 2017, up from less than 1% a decade ago. Natural gas is now the top fuel for electricity, accounting for 32% of generation compared with 22% a decade earlier. Coal’s share has fallen to about 30%, from 49% in the same time span. California sees this mandate as a way to get to their overall goal of reducing air pollution, combat climate change and help drive renewable energy in the state.
For the metal roofing world, this may lead to new business opportunities.  According to, metal roofs are light, durable, and often made of eco-friendly recycled materials and considered one of the best roof materials for solar panels. Ease of installation, durability, and environmental benefits are just three of the reasons to consider putting solar panels on a metal roof. Here are the top 5 things to consider if you want to install solar on a metal roof:

  1. It’s easy to mount solar panels on a metal roof
  2. Solar metal roofs can host thin film panels and standard PV panels
  3. Metal roofs are durable and can outlive your solar panels
  4. Solar panels can increase the cooling benefits of a metal roof
  5. Metal roofs and solar panels generate an eco-friendly home
