Our Services
Solar PPA (Power Purchase Agreements)
A Solar Power Purchase Agreement (PPA) allows businesses and property owners to benefit from solar energy without the upfront cost of system ownership. Through a PPA, a third-party provider installs, owns, and maintains the solar system while you purchase the energy it produces at a predictable rate. This model helps reduce energy expenses, improve cash flow, and provide long-term price stability while supporting sustainability goals.
Energy Storage Solutions (ESS)
Energy Storage Solutions (ESS) enhance the value of solar by storing excess energy for use during peak demand periods, power outages, or times of limited solar production. Battery storage systems improve energy resilience, reduce dependence on the utility grid, and help optimize energy consumption. Whether paired with a new solar installation or integrated into an existing system, ESS technology provides greater control, reliability, and long-term energy savings.
Prepaid PPA
A Prepaid Power Purchase Agreement combines the benefits of a traditional PPA with the financial advantages of making a one-time upfront payment. This structure allows customers to lock in energy costs for the long term while avoiding ongoing monthly PPA payments. Prepaid PPAs can deliver enhanced savings, predictable energy expenses, and access to solar energy without the responsibilities of system ownership, making them an attractive option for organizations seeking both financial and operational efficiency.

"Darrin with One More Door Solar was fantastic to work with from start to finish. He was extremely communicative throughout the entire process and always kept us informed every step of the way. He stayed present and involved from beginning to end, which made everything feel smooth and stress-free. What really stood out was that he stuck to the timeline he gave us and followed through on everything he promised. It’s rare to find someone who does exactly what they say they’re going to do, and Darrin exceeded our expectations. Highly recommend!”
Sarah Dobiesz

“This is a great Solar company
Derrin explained everything and a lot!!
It was a huge job!
We had JUST purchase our home, significantly larger than our previous home.. we had estimates from 4 other companies.. having purchased solar for our previous home… we wanted to ensure a better more efficient company
This job was huge and we rushed them as much as we could, especially after receiving our first SCE bill! Over 900. Bucks for less than half a month!!
They did an amazing job”

"Darrin and One More Door we’re great to work with in getting solar panels for our home! He was always available for all of my questions and concerns."

"Not sure if I have enough words to describe Darrin Kubancek from one more door. We moved to corona a few years ago and bought a house that came with solar. However unfortunately we were given no information about our panels . I reached out to Darrin and he responded immediately to my call. Not only did he guide me over the phone but came by and took a look and advised me on how to proceed. He gave me all the information and steps of what needs to be done. I am very grateful and thankful that there are some honest people in this world. THANK YOU so much Darrin ! I recommend you a 1000 %"
