Can You Install Solar Panels and Still Use the Electric Company? A Real-World Experience in Seattle

Introduction

Renewable energy, particularly solar power, is becoming increasingly popular as a sustainable alternative to traditional electricity sources. But what about those who still wish to use the electric company while generating their own power? This article explores the experiences of installing solar panels in Seattle and the benefits it brings, as well as the financial and practical aspects.

Real-World Installation

I recently installed a 22KW nominal solar PV generator, consisting of 55 panels, in my spacious house located in the rain-soaked city of Seattle. My home consumes approximately 50 kilowatt-hours (KWh) of power per day, and my roof, though complex and not ideally suited for solar power generation, still manages to produce excess energy even on overcast days.

Benefits and Credits

Seattle City Light, the local utility company, credits you for the excess energy generated at the same rate they charge. This means that the only cost on my first electric bill after the generator was activated was a $14 connection fee. In the winter, when my consumption increases and the generation of energy goes down, the excess generation will offset my bill.

Cost Investment and Payoff

The total cost of the solar PV generator, which includes a 20KW battery, was around $84,000 upfront. The federal tax credit is 30% on the installation cost, and sales tax is waived on solar installations. I expect the cost savings in electricity to cover the full cost of the system before the lifetime of the panels. Because of the battery component, I anticipate a payoff period of 17 years, but it could be shorter. Without the battery, a simpler system might have paid off in as little as 9 years.

Installation Process and Company Review

Installing the solar panels was a straightforward but significant undertaking. Sunergy Systems, the company that installed the panels, was highly recommended and indeed, I have only positive feedback to share about their service. They provided excellent customer support and ensured a smooth installation process.

Reliability and Security

Electricity in Seattle is reliable, but in the winter, we occasionally experience brief power outages due to wind blowing tree branches into power lines. My solar PV system is designed to switch over to battery power seamlessly during outages. This differs from the typical 5-10 seconds it takes for a gas-powered generator to start and provide backup.

Given Seattle’s frequent earthquakes, the resilience of the solar generator is crucial. If the power grid is disrupted, my solar system can power essential lights, refrigeration, cooking, and heating or air conditioning during daylight hours. The panels also power my residential elevator, which is vital for my disabled wife's mobility.

Unexpected Benefits

The presence of solar panels on my roof not only reduces my carbon footprint and saves money on electricity, but it also has an unexpected additional benefit: the panels keep the roof cooler in the summer. As a result, my home is noticeably more comfortable, an unexpected bonus of the installation.

Conclusion

In conclusion, installing solar panels in Seattle can be highly beneficial, even if you still use the electric company. The financial savings, improved reliability during outages, security during natural disasters, and unexpected benefits like a cooler roof make this a worthwhile investment. If you're considering going solar, it might just be the right move for you, too.
