Making an honest selection

At SolarEmpower, we aim to provide our readers with fair and impartial reviews that have been verified by our solar experts. The ratings of solar companies below are based on an intricate analysis of market standards, customer review ratings, and expert knowledge of the market. We believe in giving you all the information you will require, in the simplest form, so that you can make an informed and educated decision based on facts.

Key Points To Consider When Choosing A Solar Company 

Warranties:

Your home is one of your greatest assets so it only makes sense that you take extra care to ensure that your property and the solar system fitted is adequately covered in the unfortunate event of damage. A solid warranty will give you peace of mind that any damages to your home or solar system are fully covered without you needing to come out of pocket to have them repaired. SolarEmpower takes not only the length of the warranty into consideration, but also the level of coverage, as well as past experiences of real-life customers when providing a rating to ensure that you make the right choice. 

Cost VS Quality: 

Everyone wants to save money, but balancing cost and quality can be a difficult task if you do not have all the information required to make an informed decision. Due to the abundance of solar company options in California, SolarEmpower takes the guess work out of choosing a suitable company by conducting in-depth analysis of each company’s average cost against the market average, as well as customer reviews, to determine which companies offer a fair balance of cost and quality. 

Experience:  

The solar industry is more competitive than ever, with new companies entering the market every month. While newer companies may offer great prices and other promises, there is often very little information to base your decision on, apart from what the company advertises. At SolarEmpower, we conduct all the due diligence on each company, including factors such as its BBB ratings, customer complaints, and previous work samples, before we create our take on the company. Companies that have stood the test of time are always a safer option as they have earned their right to be considered as a worthwhile option. 

Best Products: 

In the solar world, reputation goes a long way. Certain solar manufactures leave no stone unturned in terms of developing the most advanced and innovative products that push the boundaries of technology and performance. We are always on the lookout for the best options in this regard while also taking real-life experience with these products into account.

The SolarEmpower View

Residents of California are spoilt for choice when it comes to the availability of solar providers and verified installers due to the state’s suitability for solar power generation.  From locally-based businesses to large global manufacturers, California has it all. We strongly recommend that customers that are considering going solar take advantage of the variety of companies on offer and gather as much information about them before making a final decision. 

Here are some of our top tips when selecting a solar company in California: 

  1. Gather as many quotations as possible
  2. Opt for companies that provide free consultations and quotes
  3. Favour companies that use well-known brands of solar equipment
  4. The cheapest option is not always the best option
  5. Pay attention to previous customer reviews
