Additional services

Customers of Sun Light & Power are also able to make use of the following additional services offered by the company:


Solar Canopies- Sun Light & Power is able to design and install solar canopies and carports that are typically ground or roof-mounted steel structures topped with solar panels. They are a smart way to produce energy from large sun-exposed surfaces while providing covered parking for drivers or shaded rest areas for people.


Battery Storage – Solar batteries are the ideal energy storage solution for homeowners who want the peace of mind that an emergency backup power source provides. Sun Light & Power serves its customers by installing high-quality home solar batteries from leading brands, such as LG Chem RESU.


EV Charging Stations – With the rapid adoption of electric vehicles, customers are able to have a charging station in their homes designed by Sun Light & Power’s qualified engineers. Businesses can apply for a rebate of up to $3,000 on Level 2 chargers for the workplace or their customers.


Solar Thermal – Sun Light & Power also offers its customers solar thermal (hot water) systems that can greatly reduce the energy needs of a business or family property that relies on a large volume of hot water. 



Installation costs and process


Sun Light & Power requires conducting a free, no-obligation estimate to all potential customers in order to provide its exact pricing based on the project at hand. As a B Corp, the company intentionally balances purpose and profit by weighing the impact of its decisions on people, the planet, and profit to be a force for good in its community.


The company informs all customers about the potential tax credits and offers no less than five financing options, each designed to meet the needs of its customer’s differing financial situations. A refer-a-friend benefit is available to existing customers, allowing them to earn cash for successful installations completed from their referrals.


The company has received 36 reviews across three sites and has managed to maintain an overall rating of 4.7*. Among the reviews are several mentions of the company being competitively priced when compared to other companies. Here’s an example:

“We had a solar company come out to diagnose the problem; they advised us that Sharp was no longer making inverters, parts were not available, so we should either live with it or have it replaced. Cost of the diagnoses was $325. Based on a tip, we called Sun Light and Power and they were immediately optimistic that it could be fixed.  After a quick visit, the failing fan was ordered, and in a week they cam back and installed the part. 

Voila, no more problems, an easy fix, and the cost was a fraction of what it would have been to replace the inverter.  The engineer was as competent as he was friendly, in contrast to our prior, expensive and curt estimate from the other company.”

In addition to its already impressive array of accreditations, Sun Light & Power was one of the first 15 Benefit Corporations in California.



  • The company uses its own extensive network of contractors to perform its services and does not outsource any of its work. 
  • Their PV systems are covered by a 25-year manufacturer’s warranty, while inverter warranties are valid for 12 years.


In addition to general repair services, the company also offers its customers additional maintenance, such as solar panel cleaning services, which helps reduce the loss of electrical energy production due to dirt and dust collecting on the surface of the modules.


Among the customer feedback were 2 reviews that received ratings of fewer than 3*; however, neither was due to poor maintenance service.  


Customer Service (Review Analysis)

Based on the customer reviews, the vast majority of customers have expressed excellent customer service levels by the company, and this is emphasized by the business owner personally responding to each customer review.


Notably, there are several mentions of the company helping customers to improve old and outdated solar systems, as illustrated in the review below:

“The company from which we purchased our solar panels went out of business and apparently took our 15 year warranty coverage with it. I searched from a company to service the system, and Sun Light and Power came through. It’s never fun to pay to fix something you thought wasn’t going to cost you a cent, but Adam at SL&P was engaging, explained how the system operates and why it fails, and was diligent in fixing the problem until I was back on line.”
