SRoeCo Solar (pronounced “es-row-koh”) is an independent, solar information website that provides objective, verifiable, solar information and seeks to present it in an easily-understandable way. It is committed to simplifying the solar installation process by providing solar knowledge, calculators, and a sortable, searchable solar panel comparison table.

SRoeCo Solar simplifies solar to help the average person feel more comfortable making an informed decision to install solar panels. More solar is better.

Sorry… as an independent company, SRoeCo Solar:

  • does not sell panels, inverters, or other solar equipment
  • is not affiliated with any solar manufacturers, installers, or suppliers
  • does not recommend specific solar manufacturers, installers or suppliers
  • provides all solar companies an equal opportunity to succeed


Q:  Who should install solar?

  • Anybody who owns a home or building and wants to save money and the environment.

Q:  What do I need to do?

  • Depends on what you want:  If you’re curious about solar, learn a little, then play with our calculators to see how much it might cost. If you’re researching and budgeting, and want to know more, shoot me a message and I’ll try to help answer any questions you have about solar.

Q:  What if I want to go off-grid/ use batteries/ use a generator/ etc?

  • Sorry, we specialize in grid-connected solar pv systems.  Going off grid and using batteries or a generator complicates things a bit.  We recommend speaking with an installation professional for anything outside of the scope of on-grid solar electric systems.

Q:  Who runs this website?

  • SRoeCo Solar was founded and is maintained by Shawn Roe. Yes, it’s named after me because a younger me thought SRoeCo would make a cool company name. I had no idea this site would get as popular as it has. It was originally built to help my 55 year old mother understand why solar was a good idea, what it was, and how much it might cost to put solar on her roof.
    Now I simplify solar in the hopes that people will feel more comfortable making an informed decision to install solar panels. I believe fossil fuel energy sources are destroying Earth and I hope to speed up the transition to renewable sources like solar before it’s too late.
    I’m an educator, entrepreneur and well-traveled father. Behind this website, I’m a real human.
