Producing energy with solar panels reduces dependence on purchased electricity from the power company. Extra energy generated can be sold back to the company or stored in batteries for later use. These steps can greatly reduce household electricity costs. Solar panels also help decrease greenhouse gas emissions, lower the carbon footprint, and enhance the value and energy efficiency.

New Zealand's main urban centers, such as Auckland, Hamilton, and Taupō, benefit from over 2,000 hours of sunlight annually. This abundant sunlight serves as a renewable and eco-friendly energy source that can be utilized in a sustainable manner. Once the solar power system is installed, the generated energy comes at no additional cost.

Solar systems can remain efficient in winter, though their performance may decrease compared to summer. The effectiveness of a solar system in winter relies on factors like sunlight exposure, angle of sunlight, and temperature. Despite these variables, solar systems can still supply a notable amount of energy in winter, especially in regions with a mild climate and clear skies. Progress in solar technology, like enhanced solar panels and battery storage, can enhance their efficiency throughout the year.

The installation duration of solar panels can differ based on factors like solar system size, installation complexity, and resource and labor availability. Typically, residential installations can span from one to three days, whereas commercial setups may take several weeks to finish.

Studies show that homes with solar energy systems have a higher resale value than those without. It's crucial to own, not lease, the solar panels to increase your property value. In numerous areas, choosing solar energy can enhance your home's value more than renovating your kitchen.
