The Details - How We Design and Install Your System

Our Easy 4-Step Process Puts Your System in Fast

 

  • Contract Agreed and Signed

   You let us know what you need and we will get a contract together on a system that maximizes your savings. We will go over the aesthetics, positioning, cost, and energy production of your system. Once signed, we will then get working on your roof!  

  • Site Survey & System Design

   We will visit your home to verify roof measurements, pitch, angle, slope, and more. Using advanced shading analyzers we determine shading issues every sunlight hour of each day. We compare the data collected during the site survey with the original contract and address any changes required. During this visit, all we need is access to your roof and electrical panel. We will meet with you to go over the design and layout of your system before installation – we will cover every detail. You will be able to picture your future with solar before it is even installed!   

  • Installation

   We install and secure your system following our strict quality assurance guidelines. If there are any changes to the schedule, we will notify you immediately. We focus on getting your solar system installed in the fastest time possible, with minimal interruption to your daily activities. Our team is NABCEP certified and has spent hundreds of hours on training and research to ensure the highest quality installations. We will keep you informed throughout the project and are always prepared to answer any questions. On average, our systems take three days to install.  

  • Monitoring

Following installation, it is time to enjoy the benefits of your new system! On our end, we track your system for alerts and efficiency. You will also be able to monitor your own system through the Enlighten smart phone application. And, if you have purchased a battery system, you will be able to view and control that operation as well. 

Already Have Solar? Replacing, Expanding, and Updating Older Systems

At OSullivan Green Solar, we commonly receive calls from clients who have solar systems already installed. Sometimes, these systems were done by companies like Sungevity, Horizon, etc. that are now out of business. We service any system, even those from older companies. These systems are often older, less efficient, and unreliable. We help with servicing and often replacing these systems with the latest technology. Often, we can increase the energy production many times over. In addition, if you already have a system and are looking for a power boost, we can also discuss expanding your system.
