Case Study

The Problem
Bill was spending an average of $460.00 per month with PG&E.      Tired of expensive electricity bills, Bill contacted HelioPower to learn about solar. After reviewing all of the available options Bill elected to install a 6.58 kW solar system from HelioPower. There were central inverter systems suggested by other companies, but because there were shading issues we suggested using micro inverters, which we found would produce more energy. Now, he is expected to save an average of $3,000.00 annually over the next 20 years.

The Solution
Together, Bill and HelioPower decided on installing 28 ET Solar 235 Watt polycrystalline panels South-facing because southern exposure produces the most energy. The system as designed, offsets over 76% of Bill’s expected annual electric bill by generating over 7,000 kilowatt hours per year. Bill financed his system using SunRun financing which allowed him to go solar for $0 down and saves him over $220 per month instantly! We engineered the system to work with Bill’s roof so that the panels were placed in the least noticeable spot and also tilting the panels to produce maximum power.

Benefits
Bill is estimated to save over $100,000 in the next 20 years. Bill chose SunRun because they “Take the Risk Out of Going Solar” by offering a Power Purchase Agreement (PPA) that includes monitoring, insurance, maintenance, and even repairs, all for $0 down. This means that if Bill wish to run the air conditioner on a hot day, he can do so without worrying about breaking the bank while enjoying clean renewable energy generated by the sun. To Boot, Bill is also enjoying a modest increase in the value of his home.

Customer Testimonial

I want to thank you for the great job you and your installation team did on designing and installing our solar system. Our PV system has been working flawlessly since early May of this year and our last two month's electricity bills from PG&E have fallen from the mid-S400 range last year to the mid $70 range. ln addition, your total price for the system was about 10% less than the three proposals we got from REC Solar, SolarCity, and Sungevity.

Your salesman was very responsive to my questions and suggestions as we went through the sales and design process. He also spent time at our home during the installation to make sure I was satisfied with everything.

Jorge and Dustin were conscientious, hard working, and efficient throughout the installation. They left the worksite clean and organized, the quality of their work was excellent, they completed the installation on time, and we passed inspection on the first visit.

I also want to thank your design team and installation team for accommodating my request to change the, design from using a central inverter to using micro inverters. The system has been producing more energy as a result and we are able to monitor its performance at the module level and manage shading much more efficiently.

Lastly, I want to thank Danielle Kraack for her accurate and efficient processing of all our rebate paperwork. She handled the entire process quickly and without a single problem, which made it easy and seamless for us. I would be happy to recommend you and your team to any prospective customers in our area. You all did a great job and the electricity bill savings are exciting.
