Frequently Asked Questions

Can I really install my own solar electric system?

Yes! Over half of our customers install and maintain their own solar power systems. Some hire extra help for part of the installation. Most have an electrician connect the wires to your home electrical panel.

If you commit to the research, there’s nothing stopping you from completing the entire installation yourself. Of course, if you get stuck, our experienced design and support team is here to lend advice and get you back on track.

Can I build my own solar panels?

We suggest leaving solar panel manufacturing to the companies who keep tight control on production quality and safety. You can find information on the web about building DIY solar panels, but we don't recommend it because the panels would not be approved for permitting.

However, there's plenty you can do yourself—sizing your system, picking components, mounting and installing the solar panels, inverter(s), safety disconnects, and so on. The more you do yourself, the more you’ll save.

How big of a solar system will I need?

Your system size depends on your unique circumstances. Some common factors that influence system size are:

  • current energy usage
  • budget
  • available build space
  • temperature
  • exposure to sunlight
  • future plans for system expansion

We have two calculators to help you size your system:

To understand what we factor into these calculations, take a look at our article: "How Many Solar Panels Do I Need?"

Of course, there’s no substitute for personalized help. Give us a call at 1-800-472-1142 to connect with an expert solar tech. We’ll help you design the perfect system for your needs.

How much does DIY solar cost?

The cost of your system will depend on how much electricity you plan to use. To estimate the answer to that question:

  • Check your electric bills for how much power you use during your highest months of usage.
  • Decide whether you’ll be paying for an installer or not.
  • Learn about the solar incentives that may be available to you.
  • Contact your county or city building department to learn about installing "to code"—both for safety, and to pass inspection.

In over your head? Call us at 1-800-472-1142.

Can I self-install a grid-tied solar power system?

Many of our grid-tied customers do. Grid-tied solar—for homes that are already plugged into utility power—is less complex to install than off-grid and can be easily expanded.

Because you are tying into the utility grid, your installation may be more regulated. Check out the regulations, legislation, and policies in your state, and plan to have an electrician or licensed contractor do the final hook-up.

Can I self-install an off-grid solar power system?

Of course! Off-grid solar power is for independent-minded people who want no restrictions on where they choose to live. Off-grid solar power allows you to buy undeveloped land that you can afford more easily. Where other people wouldn’t have power, you’ll have clean, effective solar energy.
