Utility net metering agreement

Average time: 1 week

Residential solar systems often generate more electricity than your home uses during daylight hours, so you’ll need a net-metering account with your utility. Most installers will help you select the right plan to ensure optimal savings over time.

How should you choose a solar provider?

Choosing to go solar is a valuable investment. Selecting the right solar provider is an important decision that can make for a smooth transition and impact overall system performance. From providing an initial quote and arranging financing, designing and installing the system, to maintaining it over time, there are many aspects that your provider manages.

Key factors in choosing a solar provider

  • Experience: How long a solar provider has been in business isn’t the only sign of a good provider, but it helps. Look for how many years they’ve been in business and how many systems they’ve installed.
  • Customer rating: Customer ratings sometimes don’t tell the whole story, especially if the review is only about the initial phone call. But reviews and testimonials are good insights into overall customer service and response time.
  • Workmanship: Look for certifications, licensed contractors, and photos of completed jobs.
  • Final solar quote: A good solar provider will be transparent. Make sure they list out all your estimated costs with projected savings, system installation, and maintenance costs, as well as product warranties to help protect your investment.
  • System components: Look up what panels and inverters they offer. Some providers have a wide range of types.
  • Timing: It’s a good idea to look at a solar provider’s average wait time for installation. Ask when they would schedule your installation.
  • Guarantees: Make sure they provide product and performance warranties. Look for length in coverage. The standard is 20 year warranty for solar panels, which leaves you worry-free for the duration of your lease or loan or purchase.

Which solar panels should you use?

When selecting solar panels, review the following details with your solar provider:

  • Best value for your targeted savings: Depends on how much usable roof space you have, panel power production, and cost.
  • Aesthetics: Panel color and mounting systems can be beautifully designed to integrate well with your home architecture.
  • Panel manufacturer quality and warranties: Protect your investment by picking high-quality panels backed by 20–25 year warranties.

Which solar inverter should you choose?

Inverters transform the solar electricity generated by panels (DC power) into useable electricity (AC power) for your home. Typically installed near your home's electric panel, the inverter you choose should be determined by the design of your system.

Types of inverters include:

  • String inverters: Convert electricity from multiple panels.
  • Microinverters: Convert electricity from a single panel.

When selecting solar panels, review the following details with your solar provider:

  • Inverter manufacturer track-record and warranties: String inverters typically carry a 10-year warranty and may need to be replaced during the life of your solar installation. Microinverters sometimes carry 25-year warranties and may not need to be replaced.
  • Best fit for your solar installation: The choice of string or microinverter often depends on how much shade your roof gets. Discuss with the solar provider what makes the most sense for your situation.
