Solar energy is a clean and renewable resource that can be used to heat water or produce electricity with the installation of a solar water heater or photovoltaic (PV) system. It can help save money on your monthly electric bill, contribute to a cleaner environment by reducing the amount of fuel used to make electricity, and can increase the value of your home. Solar water heating systems can last 15 years or longer and PV systems can last for 30 years or longer.
Solar Water Heating
Consider installing a solar water heater first. Heating water is one of the biggest uses of electricity for many households in Hawaii. Installing a solar water heating system is a smart first step that could reduce your monthly electric usage by up to one-third.
Rooftop Solar (PV)
Solar electric systems, also known as photovoltaic (PV) systems, convert sunlight into electricity. "Grid-Supply" PV systems return excess energy generated during the day to the electric grid and generally rely on their utility to provide power at night. "Self-Supply" PV systems use batteries for storing electricity and using later in the day, and are still connected to the utility in the case that extra energy is needed.
Don't have rooftop access to install solar panels on your house? You can still take advantage of the benefits of clean solar energy by investing in a community solar project. Your share of the revenues from the solar farm will help to reduce your electric bill every month without having anything installed on your property.
