Sullivan Solar Power is a trusted installer of SunPower panels and systems. This is a good indication of the quality of work that Sullivan Solar provides. The SunPower panels are some of the best monocrystalline panels available. The benefit of monocrystalline cells is that they are much more efficient than the cheaper option of silicon cell panels. These particular panels are made using a patented structure called the Maxeon cell. They are copper based to maximize efficiency and power output from the panels and for better durability. They come in an all black cell to reduce the glare from your property and for a better aesthetic. They also do not have the noticeable lines that are usually found on solar panels.

Panel information

You will be able to purchase either a central inverter – a larger model that adapts the power from your panels to a compatible and usable power form, such as electricity – or a microinverter. A microinverter is a much smaller model that is attached to each panel and doesn’t allow lower performing panels to affect the highest performing ones.

Installation & Monitoring

Although you don’t have a choice when it comes to which manufacturer of panels you’ll purchase from, if you use Sullivan Solar, you won’t want one. SunPower provides some of the best panels and systems on the market. As a trusted provider of its products, Sullivan Solar is committed to seeing you through the process from start to finish. There’s no outsourcing for any part of your solar power project so you’ll deal with your qualified, government certified electrical and solar technician and they’ll deal with the permits, paperwork and design of your system. You’ll be provided with a customized solar power system that works the best for your property. Once it is up and running you’ll have a 25-year warranty for the panels from SunPower (upheld by Sullivan Solar) and a 25-year warranty provided by Sullivan Solar for the workmanship.

You’ll be able to monitor your solar power usage, output, efficiency and bills on the SunPower Monitor app. It gives you an easy interface and access to all your solar information in one place. It is compatible with Apple and Android.


The most popular panels made by SunPower are the E-series and the X-series. The E-20 panels provide 20% efficiency and the X-series have a newer design that allows them to give 21.5% efficiency. Compared the market where 15% efficiency is often considered to be very good, it is clear that SunPower manufactures panels at the top end. The efficiency is defined as how much light hitting the panels becomes useful power such as electricity. SunPower believes the panels they provide will have a useful life of 40 years. They and Sullivan Solar advise keeping the panels clean to ensure the components stay in proper working order and to reduce corrosion that may affect efficiency levels.

Environmental impact

Sullivan Solar is proud of the effect it has already had on the environment, and offers a guide on its website to show how many customers have chosen them as a trusted supplier of solar panels and the effects that has had.

Cost & Savings

Sullivan Solar’s customer average shows it takes approximately six years to pay off a residential solar system. After that you’re simply saving on your bills and using clean energy too.

You can:

  • Lease your solar power system – this agreement allows you to rent the high quality panel system at a fixed, low monthly rate and use the electricity. You don’t own the equipment but you do get the power.

  • Finance your solar system – you can take out a loan through schemes such as HERO (Home Energy Renovation Opportunity) and PACE (Property Assessed Clean Energy) that allow you to pay off your clean energy system through your property tax. The loan is paid back at a low interest rate, you are eligible for the 30% federal tax credit and local incentives.

  • Buy your solar system – you can buy your solar powered energy system outright and own the power and the equipment. Eventually it will have paid for itself in the money you’ll save on energy bills and you’ll add $20 – 25,000 to the value of your property.

The average SunPower residential system can cost between $15 000 and $ 40 000 depending on your energy needs and the size of your property.

Customer Support

You can call to speak to a technician at Sullivan Solar Power during normal business hours, Monday – Friday. You won’t be given a specific person to call but you will have a saved profile with the company so they’ll be able to easily see your details and the system you have in place. If you’re using the SunPower monitoring system, this will make it easier as Sullivan Solar will be able to see exactly what the problem is on your monitoring system. You can easily email or use the contact form provided if it is not an urgent query, and someone from the team will get back to you either by email or telephone. The accreditation they have from NABCEP is a testament to their abilities as engineers and outstanding customer service.
