Great service

This is a great company that provides quality work. I had a bird do damage with a nest. I was not reading my emails to know there was a problem so I received a call from the company. They came out and fixed it.

Return On Investimate =8.5 years

The system is paying for itself. I purchased the system from Del Sol Energy because they provided the best ROI, out of six bids from companies.

Great Experience

Peter from Del Sol Solar did an outstanding job of going through the whole process for us. He maintained communication throughout the process and answered every question and visited the house to explain how things worked for us. The whole experience was great from start to finish.

The company is first rate. We dealt with Brody and he was very professional and walked us through the process one step at a time. It was great, know surprises. We would recommend this company to anyone. Thanks for all the help. Craig and Debra Fry

Everything they told us was true. Their phone app is great. Tells you whats happening on your roof every hour of the day. Recommended them to our neighbors. Ask for Elvin.

Neigbors jelous of my Del Sol Service!

Several of my neighbors who went with different companies were very jealous of the level of service, and how quickly the installation was as well as how fast I was on the grid.

Great Solar Company

Great company to deal with... I had a smaller solar system that was installed in 2013 by the previous homeowner and it was too small for my needs. I had contacted several solar companies and no one would touch it, all wanted to sell me a new system, but not touch the existing one. I wanted to get new panels and combine the systems into one smart system that I can monitor, as the old systems had a garbage string inverter that had failed 2x in 3yrs. and had to be replaced under warranty. but we could not know if it was working or not unless we actually look at the inverter. Elvin was nice enough to draw a plan to add a 2nd system, retrofit the existing system and add individual micro-inverters to each panel, so we can monitor the entire system. the price was great, the work was great and the system is producing plenty of power as we now have about 120% of our normal consumption. so no more true-up bills, my last bill was only $34 for the 6 months the new one had been running, keep in mind that in Jan 2022 when the system was installed my true-up was estimated to be $480+ that was the midpoint as my bill is every July. So, 6 months to eat up the true-up, I expect this year we should have a check from PG&E instead. Elvin also recommended DeltaSchools CU for the loan, and it was painless. Great Job Elvin and Del Sol Energy! Highly RECOMMENDED!

Excellent Company!! Worth it!

Brody and Del Sol were excellent from start to finish. Brody stayed with us throughout the entire process and ensured that we understood when the contractors would be here to work, to when (approx.) NV energy would be here to switch out the meter. If your looking for a VERY trustful solar company, give them a call, you can't go wrong!!

Amazing experience with Del Sol Energy!!

Amazing experience with Del Sol Energy!!! From the 1st day we walked into their showroom until the day of completion we were 100% satisfied. Brian did an amazing job explaining everything and answering our many questions throughout the process. Everyone from the office staff to the installers were very professional. The timeline on the installation that was given to us went exactly as stated and the job was completed perfectly. We couldn't be more pleased. The ENPHASE App is awesome as it shows exactly what were producing, as well as our consumption along with what we are sending back to the grid and it's so exciting to see the daily results. We HIGHLY recommend Del Sol.

Solar

TOP NOTCH, can not say enough about this company. Peter the salesman’s was honest and true to his word. Sold me the system that I needed did not try and sell me something that was not necessary. Josh the owner was also awesome. I had a horrible solar experience my first time around and these guys changed my opinion on the way solar should be done. If you want awesome communication and jobs done timely at a fair price than this is the company that you want. My job minus the HOA was done completed and turned on in less than a week. They said they where coming and showed up on time and cleaned up every day and the whole crew was awesome. I would continue talking about these guys by I would just start repeating myself.

Easiest Process

We talked to 3 different solar companies. We like the Del Sol person the best. We weren't ready to install, at that time. Our sales rep called once a month to say hi and see where we were at. Then he sent an email with an offer because another deal fell through. We decided to take it. Del Sol came to the house. We filled out the paper work in minimal time, they were also very nice. The panels were installed in two days and they turned it on really quick - my sister waited 6 months for theirs to be turned on. We have been having $0 electric bills. I am excited to see how low they are this summer! My neighbors had solar installed. We both have the same type of roofing. I noticed later they had dry wallers and painters at their house. They had leaks from the install and the people used to fix the problem weren't very professional. It took weeks for the repairs to be made. We have had a ton of rain since the panels were installed. We are still dry.

Solar Panel Installation

Overall, we are quite pleased with Del Sol NRG and the solar panel installation on our home. It has been operating trouble-free since it was installed in early November 2017. There were a couple of minor issues with the installation which when brought to Del Sol's attention, were corrected promptly. I like the on-line interface which allows me to easily track the performance/output of the system.
