No matter what time of year, Hawaii is never more than a few days away from sunny skies. The naturally temperate climate of our Islands presents ideal conditions for getting the most out of a photovoltaic (PV) system – translating to lower energy bills and a better environment for all. 

Beyond the upfront costs of installing such a system in your home, think about the long-term savings on energy bills and other auxiliary costs that can add up over time. David Gorman, RevoluSun SmartHome general manager, says that utilizing solar panels can potentially save you more than $100,000 over the span of 25 years, as opposed to using a nonrenewable energy system.

Factors to Consider

Future Proof

If you expect your energy needs to increase in the future, choose solar panels that are able to accommodate those needs, even if you don’t need them now. 

Workmanship Matters

Installation will require holes to be drilled into your roof. Ask your installer how they plan to prevent leaks from happening.

Discover great ways to finance your clean home energy system.

Not only do photovoltaic systems save you money, in the long run, but they’ll add to your home’s overall market value too. It makes sense, then, to invest in a quality PV system for your home, whether you plan to sell soon or live there for the foreseeable future. 

With both hard and soft costs for solar panels, it can be difficult to determine a budget by yourself. Work with your solar contractor to establish an estimate you’re comfortable with, then explore your financing options and pick the one that best suits you. 

A short-term personal loan is a great and flexible way to finance just about anything. Typically, loan terms will vary between one and five years, with the interest rate set based upon your credit. These types of loans also come with a quick turnaround time, affording you the financing you need if you’re in a hurry. 

Many banks and credit unions are starting to offer green loans, too. These are special loan programs that have unique stipulations for homeowners looking to invest in a new clean energy system. These loans may have exclusive rates and payment terms as they work directly with participating contractors, so be sure to weigh your options before applying. 

Once you’ve installed your clean energy system, be on the lookout to see if you qualify for any tax credits or rebates being offered. Consult with your credit union, bank or tax adviser to be sure.
