Yes. We coordinate all permits and inspections end-to-end. This includes city/county permits for electrical work, generator installations, EV chargers, and panel upgrades. Inspection scheduling is included.

Do you serve my city or ZIP code?

We cover all of King, Pierce, Snohomish, and Kitsap counties in Western Washington. Major cities include Seattle, Bellevue, Tacoma, Everett, Kent, Federal Way, Sammamish, Issaquah, Kirkland, Auburn, Gig Harbor, Maple Valley, Bonney Lake, and 100+ surrounding areas.

Are there EV charger rebates available?

Yes — utility programs vary by provider. PSE offers up to $1,000, Seattle City Light offers $500-1,000, Tacoma Power offers rebates, and Snohomish PUD has programs. We check eligibility during booking and handle paperwork.

How long does an EV charger installation take?

Most Level 2 charger installs take 1-2 days. If a panel upgrade is needed, allow 3-5 days total. Permitting adds 1-2 weeks but we coordinate this while ordering equipment.

What size generator do I need?

Typical homes need 16-22 kW for essential circuits (fridge, lights, heat), or 22-26 kW for whole-home backup. We perform load calculations during site visits to size correctly. Generac Guardian Series 10-26 kW are most common.

Do I need a panel upgrade for an EV charger?

About 60% of homes do. Most Level 2 chargers require a 40-48A circuit and 200A service. Homes with 100A or older panels typically need upgrades. We assess during free site visits.

What is the typical cost to install a Level 2 EV charger in Western Washington?

Most standard installs fall between $1,200-2,500 depending on panel capacity, run length, and permitting. Sound Power provides a written scope and pulls permits. EV Charger: $1,200-2,500 installed. Panel Upgrade: $2,500-5,000. Standby Generator: $8,000-15,000 installed.

Do you work with solar installers?

Yes. We handle the electrical wiring, interconnection, and utility coordination for solar PV systems. We partner with solar panel installers or work with your chosen company. Battery backup (Enphase IQ) integration available.

What brands do you install?

EV Chargers: Tesla Wall Connector, ChargePoint, JuiceBox, Grizzl-E, Emporia. Generators: Generac (Authorized Dealer), Kohler. Smart Panels: Span, Lumin. Monitoring: Emporia Vue, Sense. Battery: Enphase IQ Battery systems.

Do you offer financing?

Yes. We work with financing partners for projects over $3,000. 0% APR for 12-18 months often available (subject to credit approval). Ask about options when scheduling.

What is your response time?

Within 1 business day for quotes and scheduling. Same-day emergency service available for critical issues. Most installations scheduled within 1-2 weeks of estimate approval.

Do you provide warranties?

Yes. Our workmanship is guaranteed for 1 year. Equipment warranties vary: Generac generators (5 years), EV chargers (3 years typical), Enphase batteries (10-15 years). We facilitate all warranty claims.
