Quality and Efficiency

Immediately visitors get the sense that Horizon Solar is a big name in solar electric systems in California. In fact, Horizon Solar Power places itself as the ‘premiere provider of solar energy in Southern California’. It has been in business since 1999 and helped over 8,000 Californians switch to solar, so it’s obvious that it has some clout when it comes to experience and expertise in getting the job done.

The site over all reflects the efficiency and quality of its work. This is summed up by the speed at which it provides installation, with lifetime guarantee and ongoing maintenance. Horizon Solar Power clearly places a big emphasis on the quality and efficiency of its installers, too - thanks to a range of locally-based, fully trained installation teams.

Cost and Finance Options

There are a range of finance and payment options for anyone wanting to go solar with Horizon. You wouldn’t expect anything less from a name like this who have been in the business for the best part of 20 years.

Payment options are similar to most other solar electric system providers and installers. Horizon offers its customers the ability to buy their solar system outright if they wish, or alternatively finance their newly-installed system with a range of loan products. The other option is for customers to benefit from their zero-down Power Purchase Agreement (PPA) option. Essentially, this is a financial arrangement in which a provider owns, operates, and maintains the photovoltaic (PV) system, and the customer agrees to purchases the system's electric output from the solar services provider for a predetermined period.

Horizon Solar also focus heavily on savings - with customers being able to benefit from as much as 30% right from day one, and lock-in rates for 20 years.

Manufacturer’s Experience/Portfolio/Reputation

Horizon Solar’s experience and breadth of expertise is impressive. It bills itself as California’s leading solar electric system installer, and by helping over 8,000 Californians switch to solar, and delivering a great commercial offering, it’s easy to see why.

The site also has some great photos and examples of previous systems that they have installed - something that many providers actually forget to show or mention, so this is a great quality reassurance. Quality that’s confirmed by the testimonials and video testimonials scattered throughout the site, by both customers and commercial business owners alike. It’s clear that Horizon comes well recommended and prides itself on reputation.

Structure and Installation

Horizon Solar’s speed of installation is down to its straightforward process and highly-trained and locally-based teams. Things start with an initial consultation, where a Horizon Solar Expert will help you figure out if solar is right for your home or business, and if so, which system is right for your needs.

Horizon Solar will then help demonstrate how that system will work best for you and provide you with a full proposal outlining everything about the system, its technology, components, as well as all the finance options, and warranty & maintenance options available to you. Installation itself is handled by their highly-trained, locally-based teams from start to finish, and the whole system is often up and running in a few days.

Warranty and Maintenance

From a company that prides itself so strongly on quality, service and experience, you would expect the warranty and maintenance side of things to match – and it does. Although there isn’t a great deal of ‘pre-sales’ information on the site about exactly what’s covered, Horizon do make the highlights and benefits of going solar with them, very clear.

Not only do customers get fast installation, lifetime guarantee and no-money-down at the outset, but they benefit from ongoing maintenance that’s optional with their partnership with Sunrun; 20 year lock-in rates and big savings. Types of warranty coverage vary based on your home or business set-up, personal needs or energy goals, and the type of system you go for. 


If you’re looking for a really solid Solar electric system installer in California, then Horizon is the one to check out for both residential and commercial needs. It has the size, clout and experience to offer good coverage across the state, fast installation, a range of payment & financing options and big savings. Not to mention exemplary service from their highly-trained, locally-based teams.
