We had ZeroDown Solar install 18 panels and a couple of 240V outlets. We could not be happier with ZDS. The owner, Simon Tatersall is a no BS guy and gave us options that met our needs with no hard sell to oversize the system. He really knows his stuff and gave us a simple, honest explanation of how it all works. His pricing is noticeably better than the big guys. His team did a great job on the installation which was completed quickly. Furthermore he follows up to make sure everything is working properly. In our case, one of the microinverters was defective. Simon picked up the problem

Took us almost a year and half to decide whether to go solar or not. A lot of information to consider and to digest making it more difficult to make a decision especially with this type of home project investment. With ZDS and working with Simon, he provides a lot of information and explained the whole process from beginning to end. Easy to talk to and always available for any questions. Overall, had a good experience with ZDS and his crew ( Jason and Robert). Both professionals and result-oriented in their respective fields. Thank you very much.

Simon and his engineer were able to come out to a house that I had listed/in escrow and figure out why the solar panels installed by another company weren't working at full capacity. The home seller had been struggling with the other company for years and they had never performed at full capacity. Zero Down Solar was able to fix an inverter and get 16 panels up and running that had perhaps never functioned in a chain. They worked us into their busy schedule next day and it made a huge difference in the sale and for the home buyer!

I had very good experience with Simon and ZDS. I got quotes from multiple sources and big brands. ZDS was the best quote I received. ZDS walked me through the entire process multiple times. Entire team was very professional and courteous. They give all the details on costs/warranties. Simon is always reachable via email, Text and phone and explained about all the hardware (invertor, monitoring etc...). I had no knowledge on how many panels to get, Simon guided through the process and provided multiple quotes which helped me in selecting the right Panels. My neighbor went with big brand (you can

So glad we went with Zero Down Solar! Simon was incredibly informative throughout the process, making sure we were up to date on everything. The installation and inspection was efficient, and we are so glad we now have solar!

I have been wanting to install solar for a long time, but have always been turned off because of all the horror stories of liens on the home due to leasing, leaking roofs and companies that come and go. That all changed when I met Iiro of Numa Consulting Group who designed a system based on my specific needs and with a price and ROI that worked. Simon the owner of Zero Down Solar then took over for the installation and inspection process, guiding me all the way. The system is fully warranted for 25 years and I am confident that these guys will be around for the long haul should I ever need any

Zero Down Solar just added 10 panels to the home we recently purchased which already had a 27 panel system that they installed years ago for the prior owner. The expansion was designed to completely cover our growing electrical needs including charging a Tesla, supporting a larger household, and the addition of an electric spa. I was impressed by the speed and quality of the installation, their integrity, and the seamless communication which included lots of education on the technology. The price was also very competitive.

I was referred by a friend that Iiro his friend was the best. I was half way through a deal with a different solar company that I was not happy with. Iiro from Numa Consulting group reviewed the whole system and explained to me what was possible for the same amount or even less. I got a say he was super patient with me. He answered all my questions intelligently and understood what my vision was for my electrical requirements. One year later from first talking with him we finally got our solar system installed. I’m super happy with my system and super happy having worked with Iiro from Numa Consulting

I decided to go solar a couple months ago, Iiro and Simon were great they answered all my questions even spending extra time with me to make sure I understood everything. Iiro helped walk me through the financing so everything went smoothly. The installers were prompt and professional. They showed up when they said and completed the job quickly. I received my first power bill and even with "May gray" my panels produced more than I used. I am very happy to never pay for electricity again!

This was my first solar experience and it went really well! I was introduced to this company by my solar consultant, Numa Consulting Group. I have a house and a guest house, so I was recommended to install a large 31 panel system. It's been a couple weeks and the results already seem great! Iiro, Simon and their team were professional, courteous, responsive and efficient. They installed the system quickly kept to the timeline they promised. Do not hesitate to call them for your solar system!

I highly recommend Zero Down Solar. Iiro from ZDS patiently answered all of my questions about solar energy and thoroughly explained the whole process of installation. The Company's estimate was fair and in line with other estimates I had obtained. Iiro constantly monitored the installation and everything went smoothly from start to finish. Zero Down Solar definitely went that extra mile to ensure that I was happy with the completed project.

Zero Down Solar installed eighteen 300 Watt panels on our new home at the end of 2017, and so far in 2018 the financial benefits have been more than we expected.
Having all aspects of the solar install handled efficiently made the whole process very easy and finding a local solar company that has been completely trustworthy and reliable has been a blessing. Iiro Yrjola, was the person that assisted me in finding this company, I am very pleased with this man, he has helped me twice getting solar, on 2 different homes, he always knows what is need and will help out as much as possible.

The folks from ZERO DOWN SOLAR installed a 7.8kW system - 26 panels - for me in Dec 2016.
I have been very satisfied with both the energy that our solar array has produced - and the customer service from this company.
They took great care to ensure that I was happy with the work, answering all my questions and coming to check on the installation several times.
SDGE has reported that our solar panels have produced more power (kWh) than we have used, and it is such a relief not to have to pay SDGE every month.
So I am very happy with the prospects of not having to pay for any more energy bills

Zero Down Solar just finished installing solar panels on my house and I could not be happier.
The whole process (from design to 'Permission to Operate' from SDGE) was handled by Zero Down Solar (including help setting up a $0 down solar loan) and it was all completed in about 2 weeks. And I was kept informed of every step in the process, including how to monitor the power production from my phone.
I am so happy with both the service and price and have the highest praise for Zero Down Solar.
It was a very easy and pleasant experience.

Well, I finally went Solar and I couldn't have picked a better business than Zero Down Solar. It all started on Nextdoor when I was asking for recommendations about a solar company that had contacted me. I was approached by and met with Iiro of Zero Down Solar. I now have a book (which I created) with all the information that anyone could want regarding solar. Iiro took the time and energy to answer all my questions and provide data to back up what he was saying. When we ran into a roadblock Iiro was able to work me thru it. I would strongly recommend Zero Down Solar for your solar needs

Zero Down Solar gave me a great quote and walked me through the entire process. I didn't feel pressured like I did with some other companies I'd contacted.

The whole project went off without a hitch and I couldn't be happier! I only wish I'd done it sooner.

Our recent experience in the process of installing solar panels was not only professional but also a pleasant personal experience. Iiro explained in detail the process of having the panels installed as well as helping in the financing process with the HERO program. From the time Simon's team came to inspect the roof to the final installation of panels we were very impressed with their courteous and professional actions as well as taking time to answer questions or concerns. I would highly recommend RPS to other potential customers given our great customer experience and the subsequent positive
