FAQs
What size solar panel system do I need for my home or business in Kelso?
The ideal system size depends on your average electricity consumption, roof space, shading, and future energy goals (e.g., adding an EV charger). For most Kelso households, usage falls between 20–35 kWh per day, which translates to a 5 kW–8 kW array. We begin every project with a detailed assessment of your past 12 months of utility bills, a shade analysis using satellite imagery and on-site measurements, and a discussion about anticipated changes in consumption. From there we design a system that offsets 90–110 % of your annual demand, ensuring you maximise savings while staying within local net-metering rules.
Do solar panels perform well in Kelso’s climate, which includes cloudy and rainy periods?
Yes. Kelso receives roughly 4.3 peak sun-hours per day averaged over the year. Modern mono-crystalline panels maintain high efficiency even in diffused light, so energy production continues on overcast days—just at a reduced output. System sizing calculations factor in the seasonal variation: summer surplus is banked through Washington’s net-metering program to offset winter deficits. Overall, a properly sized system in Kelso can still cover 80–100 % of a typical household’s annual electricity needs.
What panel, inverter, and mounting configurations do you offer?
We carry Tier-1 mono- and bifacial modules from REC, Qcells, and LONGi in 400–450 W formats, paired with either a central string inverter (SMA, Fronius) or module-level power electronics such as SolarEdge HD-Wave optimisers or Enphase IQ micro-inverters. String inverters are cost-effective for unshaded roofs, while micro-inverters or optimisers increase production on complex rooflines with partial shading. For mounting, we use IronRidge XR rail systems on asphalt shingles, S-5 clamps on metal roofs, and ground-mount solutions with galvanized steel piers where roof space is limited. All configurations meet NEC 2023 rapid-shutdown requirements.
How will my solar installation be connected to the electrical grid, and will I need service upgrades?
Your array ties into your existing service panel through a dedicated solar breaker that back-feeds the bus bar, allowing excess generation to flow to the Cowlitz PUD grid. We verify that your main panel has at least 125 % of the solar breaker rating (per NEC 705.12) available. If space or bus-rating is insufficient, we can either install a line-side tap, upgrade the main panel, or add a dedicated solar sub-panel. A bidirectional net-meter is installed by the utility at no charge, and the entire interconnection is inspected by the City of Kelso building department before activation.
What incentives, tax credits, and financing options are available for Kelso residents?
Through 2032, you can claim a 30 % federal Investment Tax Credit (ITC) on the total installed cost. Washington State’s sales tax exemption for solar up to 100 kW eliminates 8.1 % in upfront tax. Cowlitz PUD offers net-metering at full retail value, and any annual surplus is credited at the utility’s avoided-cost rate. For financing, we partner with local credit unions offering 1.99 %–4.99 % solar loans with terms up to 15 years, as well as PACE-style secured financing for commercial clients. Typical payback periods in Kelso range from 8 to 11 years, with ROI exceeding 8 % annually.
How long does the installation process take, and what maintenance is required afterward?
From signed contract to permission-to-operate, most residential projects take 6–8 weeks: 1–2 weeks for design and permitting, 1 day for panel and inverter installation, 1 day for electrical inspection, and 2–3 weeks for utility net-meter approval. Commercial systems may extend to 10–14 weeks due to additional engineering. Solar arrays have no moving parts and require minimal upkeep—an annual visual inspection and occasional rinsing after pollen season is usually sufficient. We include online monitoring, a 25-year panel performance warranty, a 10–25-year inverter warranty, and complimentary maintenance for the first five years.
