Frequently asked questions
Is solar worth it?
Absolutely! Switching to solar will save you money, raise your property value, and reduce your carbon footprint. Solar systems cut or entirely eliminate your monthly electricity bill and protect you from rising utility rates. Specific cost savings will depend on your solar offset, or the amount of energy your system produces compared to the amount of energy your home consumes, but you can safely expect to save thousands over the lifetime of your system.
What incentives and tax credits are available for residential solar installations?
Washingtonians benefit from generous state and utility solar incentives. In Washington, solar is exempt from state and local sales taxes through 2029.
Additionally, our statewide net metering program allows homeowners to receive credit for the extra energy their systems produce. When your solar panels generate excess electricity, it flows back to the grid, and your utility credits you the full retail rate for it. You can use those credits later when your panels aren’t producing as much (like at night or in winter). Get your panels online before your utility reaches its 4% cap or before June 30, 2029—whichever comes first—and you’ll lock in today’s full retail net metering for the life of your system.
How much space do I need for a residential solar system?
We customize our systems for every rooftop. Most homes are viable, and we assess your roof to design the right solution.
What is the installation process like and how long does it take?
From design to energization, projects usually take 3–6 months, depending on permitting and system size. Installation itself typically takes just a few days.
How reliable is solar energy for homes? Will I still have power if the grid goes down?
Standard systems shut off during outages for safety, but adding battery storage can keep essential home appliances running. We offer tailored backup options to meet your needs.
What kind of maintenance is required for a residential solar system?
Residential solar is low-maintenance. Systems require periodic cleaning and monitoring. We offer maintenance and performance tracking to ensure peak efficiency for 25+ years.
What is the return on investment (ROI) for residential solar?
With the phaseout of the Federal Investment Tax Credit at the end of 2025, most homeowners will see a payback in 11-14 years, with strong long-term savings and predictable energy costs for decades. In coming years, the payback period will likely shorten as utility rates rise faster due to changes made by the One Big Beautiful Bill.
Will solar increase the value of my home?
Yes! Solar often boosts property value and reduces utility expenses, making your home more attractive to tenants or future buyers.
Can solar help my home become more sustainable?
Absolutely. Solar is a visible, measurable way to reduce your carbon footprint and strengthen the energy resilience of your community.
What happens if I sell my home after installing solar?
Once installed, solar becomes a fixture of the home. All solar assets will transfer with the sale of the home. Solterra’s warranty is transferable and new interconnection agreements with the utility are easy to set up for the new owner. We help ensure a smooth transition.
How do I know if my roof is suitable or needs repairs first?
We perform a full site assessment to check roof condition, weight capacity, and remaining lifespan. If repairs are needed, we’ll coordinate timing to align with installation.
Who handles the paperwork, permits, and utility approvals?
We do! Our team manages all permitting, engineering, inspections, and utility coordination from start to finish, ensuring your seamless transition to solar.
