SOLAR PANELS
ReneSola 300W Polycrystalline — Used Commercial
300WA different make from our JA Solar lineup — these ReneSola JC300M-24/Ab (Virtus II) panels are 72-cell polycrystalline modules rated at 300W with roughly 15.5% efficiency. Same commercial-pull, used like-new condition: tested before they leave the yard. Slightly larger footprint than the JA Solar panels (1956 × 992 mm) and our lowest price per panel, making them a smart budget pick for off-grid and homestead systems. IEC 61215 / 61730 and UL 1703 certified when new. Sold as-is, no warranty.

Each panel is ETL certified (Intertek #5001874), UL1703 listed, and fully tested before listing. 72-cell format with MC4 connectors. Perfect for off-grid cabins, homesteads, RV/marine builds, and backup power systems. Used like-new condition — these spent their working life in a ground-mount commercial array, not on a harsh residential roof. Sold as-is, no warranty.

Used like-new from utility-scale ground-mount arrays — not harsh residential roofs. A great middle-of-the-road pick for off-grid cabins, homesteads, and backup power builds. Sold as-is, no warranty.

How to Size a Battery Bank for Off-Grid Solar (Eastern Washington)

Volts, amps, and watts, finally made simple. The water-pressure analogy that makes it click, the one formula worth knowing, and why each matters when you're building an off-grid system.
Can You Mix Solar Panels of Different Wattages?
Stringing mismatched panels drags your whole array down to the weakest one — but if the wattages are close, the loss is tiny. Here's the plain-English rundown on series, parallel, and when mixing is actually fine.

Used Solar Panels: Are They Worth It?
We sell used panels. So we have a stake in this answer — but here is the honest breakdown of when used panels make sense and when they do not.
PROUDLY SERVING
EASTERN WA AND SURROUNDING AREAS.
WA Solar Depot is a veteran-owned and operated solar supply business in Oroville, Washington.
We began selling used solar panels out of our field in Oroville because we had a few extra, but then we saw a gap — people all over eastern Washington (and as far as Idaho) wanted to go off-grid, reduce their electric bills, or build backup power for their homes and properties. But nobody in the region was supplying panels at a reasonable price.
So we connected with our partner in California who decommissions utility-scale solar plants. These aren't broken or defective panels — they're fully functioning panels that came off large commercial installations when those installations were upgraded or retired. They have many years of useful life left. We found these panels pencil out well for off-grid enthusiasts and local families.
So far we've sold over 150kw of solar panels to local families. People drive from Spokane, Colville, Seattle, even from out of state. We weren't expecting that, but it tells us there's a real need we're filling.
Now we're building this out properly: a real website, more inventory, batteries, inverters, combiner boxes, and a long-term commitment to being eastern Washington's best solar supply source. Just panels, batteries, and hardware at prices that make sense.
