Solar Panel Services - Questions & Answers

Solar panels can reduce the amount of electricity a property needs to purchase from the utility by generating electricity on-site. The actual savings depend on system production, household electricity use, utility rates, applicable utility programs, and other factors.

Yes. Solar PV systems can be installed on commercial properties, subject to applicable electrical, building, utility, and permitting requirements. Larger clean-energy projects may also be subject to additional Washington labor-standard requirements.

Solar installations involving electrical work generally require electrical permits and inspections, although requirements and the responsible permitting authority can vary by location. Washington L&I states that electrical work generally requires a permit and inspection, with certain exceptions.

A standard grid-connected solar system generally does not continue powering a home during a utility outage unless it has equipment specifically designed for backup operation, such as appropriate battery storage and controls. A solar professional can explain the available backup options.

No. A solar PV system does not necessarily require battery storage. Batteries can be added when homeowners want to store electricity for later use or have specific backup-power requirements.

Yes. Solar panels can still generate electricity when skies are cloudy, although their output is generally lower than during periods of stronger sunlight.

Solar panels generally require limited routine maintenance, but periodic inspections can help identify dirt, debris, physical damage, wiring issues, shading changes, or system-performance problems. Maintenance requirements vary by system and location.

Yes. Some solar providers offer troubleshooting and repair for issues involving panels, wiring, inverters, monitoring equipment, and other system components. Electrical work must be performed by appropriately licensed and certified professionals in Washington.

Yes. Residential solar companies commonly install rooftop photovoltaic systems. Roof condition, available space, orientation, shading, and structural considerations should be evaluated before installation.

The number of panels depends on the home's electricity consumption, panel wattage, available roof space, roof orientation, shading, and desired system capacity. A solar installer can calculate the appropriate system size after reviewing the property's energy use.

Yes. Solar panels can generate electricity in Washington, including on cloudy days, although electricity production varies with sunlight, weather, system orientation, shading, and season.

Solar installation costs vary based on system size, panel type, roof condition, electrical work, equipment, labor, permitting, and whether batteries are included. A solar company can provide a project-specific estimate after evaluating the property.

Solar companies in Washington may provide solar panel installation, system design, electrical work, repairs, maintenance, inspections, monitoring, and troubleshooting. Solar photovoltaic (PV) systems are part of the electrical construction trade in Washington.
