Expert Solar Panel Installers in Tucson, AZ

Inverters take the DC electricity from solar modules or energy storage (batteries), and convert it to AC electricity that can be used in your home or business. Some inverters are designed to be connected to the utility grid, and send electricity to both your loads and the grid. Other inverters can be used when the grid is down. Some inverters both work with the grid, but can also function when the grid is down.

For most homeowners, no. Solar leases may save you a small amount of money each month, but most of the benefits of the system go to the financing company, not you. Instead, consider financing your system with an appropriate solar loan. For business owners and non-profits, PPAs or leases may make more sense, but each situation is unique.

You may need to upgrade your panel because the current panel is unsafe, to allow connection of a larger solar electric system, to add a subpanel to fit solar breakers, or to allow installation of energy storage.

Very little maintenance is required. In addition to a free one-year checkup provided by Net Zero Solar, we recommend a visual inspection of the system each year. If installed on a built-up roof, continue regular maintenance of the roof, including new roof coating over the solar flashings.

Running air conditioners, electric heat, electric water heaters, electric stoves, or other other large loads is usually too expensive with energy storage. Lights, refrigerators, electronics, swamp coolers, small window air conditioners, some mini-splits, gas furnaces, and other similar loads are possible to run.
