Certasun services and features


Certasun Products

Certasun offers a narrow range of products, which include:

SunVault Energy Storage: This product requires no maintenance and provides 24/7 backup power. It stores energy which can be used in the event of a grid outage which, combined with solar panels, will provide enough power for a home to survive for days. By filling out a quick and simple form on their website, potential customers will be able to receive a price quote for this or any other system sold by Certasun.  

EV Charger Installation: Certasun is a fully licensed and insured EV charger installer. The company can install a Tesla or ClipperCreek charger – or alternatively, Certasun can simply install a 240 volt outlet which will be compatible with any Level 2 charger.


Certasun Costs

Certasun’s products are priced above those of its competitors – and Certasun does acknowledge this. The reason behind the company’s higher pricing is due to the equipment they install, which they claim is only of the highest possible quality.

Customers can save some money however as Certasun helps to take full advantage of Federal Solar Tax Credits, which are an incentive for residential solar. For systems installed in 2022, the credit is 26% of the cost of the system – and this figure will shrink to 22% for 2023.

Reviewers were generally happy with the pricing services offered by Certasun, with accurate quotations and comprehensive financing options.

Overall, we feel that Certasun’s pricing is justified due to the quality of service and product delivered – however, there are companies which offer better pricing.


Certasun Legitimacy

Certasun is a legitimate company:

  • Plenty of accurate information about the company is provided on its website.
  • The company is transparent with its contact details along with its location.
  • The company boasts both a good rating and accreditation from the BBB.
  • There are many reviews online which help to support the legitimacy of the company.


Certasun Maintenance

Certasun exclusively installs Sunpower Equinox equipment, which is some of the most durable and efficient solar equipment available today. The company has had two customer complaints in the past 12 months, both of which have been closed. After complaining of issues with their systems, both customers are now satisfied with the solutions Certasun presented to them after the complaints were filed.

Certasun has a guarantee for all of its solar systems, one which promises at least 90% of estimated production for the next 25 years. If it falls short, the company will compensate by paying the customer back at a rate of 12.4¢ per kWh.

With an average customer review of 4.8/5 stars, Certasun has incredibly good customer reviews, reflecting the excellent service it provides.
