1. Are solar panels worth it in Hawaii?

Yes, going solar is definitely worth it in Hawaii due to several factors. First, the Hawaiian state receives plenty of sunshine throughout the summer and considerably good peak sun hours during the winter months. Second, there are several solar incentives available that can significantly lower the overall solar installation cost. 

2. Do you really save money with solar panels?

Yes, solar panels generally deliver the return on investment in a gradual but consistent way. In most cases, solar panels pay for themselves within 6 to 10 years. However, you can increase the utility savings you get from your solar system by installing a battery system that helps you store solar energy and use it during peak hours when utility power costs go high. 

3. How long does it take solar panels to pay for themselves?

Solar panels generally deliver returns within 6 to 10 years. With a battery system, you can save more on utility expenses by storing solar energy.

However, if you do not have any budget to pay upfront or aren’t comfortable with paying a sizeable monthly financing amount, you can go for the leasing option.
