"Our experience with Sullivan Solar Power has been fantastic - the team that we worked with has been absolutely great. I had thought that solar was new and untested, where in fact everything I received from Sullivan Solar Power and have read has informed me that this is not the way of the future, it's today."

"We had the system installed in September of 2006. My bills originally when I opened this place up were about $1,200 a month. Now my average bill is approximately $52 a month. I’m a very high-level mechanical engineer, I design and build all my mobile lighting systems and trucks and so forth, and generators. Talking to them, they knew what they were talking about."

When is my ROI is expected?

The standard solar power system takes just 6 years to pay off! Even shorter in many cases. Imagine that - not only do you start saving money the day your system is installed, but after a few years your power is totally free!


How big of an installation can Sullivan handle?

There is no limit. We have a track record of multiple successful large-scale installations, including utility-scale and military. With nearly 200 employees and union-trained electricians, we’re equipped for any size project.

I’m not ready to move forward, can I just call and get some questions answered?

Of course, we’re happy to answer every question you have, even if you aren’t interested in going solar any time soon.

My business is really small, is solar an option?

The physical size, number of employees, or revenue of your company has little to do with the viability of installing a solar power system, it has much more to do with how much you are paying for electricity now and what tax benefits you can take advantage of.

I don’t own my building, is solar an option?

Absolutely, you don’t have to own your property to install solar and it can be installed with very little modification to the building. Solar systems can be cash-positive from day one, meaning you can get a return on your investment without needing to stay at your location long-term.

Is Sullivan going to be around long enough to service my warranty?

We have been around since 2004 with over 5,000 customers spread across Southern California. We are financially healthy and our commitment is rock-solid. By all measures, we will be around to service every system we install and beyond.

Does Sullivan have the technical expertise to design a large system?

Yes, in fact we have some of the top engineers in the industry. Even our owner is a State Licensed Master Electrician. We are also only the 4th company in the United States to be awarded the level of NABCEP Accredited PV Installation Company!




We use the latest in cutting-edge technology. Our panels are some of the highest efficiency and longest lasting in the industry.



We are among the very few solar companies who proactively monitor the health of your system. If something goes wrong, we’ll know right away and schedule a service.



We don’t cut corners on this often overlooked component of a quality solar power system, we only use inverters designed by the manufacturer to match your system.



Our mounting techniques allow us to install solar systems on almost any type of roof or ground conditions. We don't penetrate your roof so threat of leaks is nearly zero.

Maintenance of your Solar Power System

Occasional washing

Your solar panels will perform best when clean. Several times a year it is a good idea to rinse off your panels with a hose and wash away any dust, dirt and debris.

Watch for shading

Over the average 30 to 50 year lifespan of your panels, it is likely some of your trees will need to be trimmed to avoid casting shade on your solar system.

Inverter space

Make sure to leave some open space around your inverter as it contains electrical components and needs a small amount of ventilation.
