Yes. Choose pickup at checkout and collect it at 3820 7 Street SE, Calgary. We email you when it's ready. The counter is still being finished, so wait for that email, then call 587-287-9180 or email hello@maplesolarsupply.ca to set a pickup time.

Not yet: the counter is still being finished. Order online and we'll email you when to pick up.

No. You can check out as a guest.

Yes, anywhere in Canada. Small parts go by courier, at the rate shown at checkout. Panels and racking rail go by freight: it isn't charged at checkout. After you order, we email you a freight quote, palletizing or bundling included. You pay it before they ship, or cancel the order for a full refund if the quote doesn't suit you. Shipping policy

Yes. GST is added at checkout.

On new panels, yes. From 1 October 2026 Alberta charges $14.00 on every solar panel of 1 m² or larger. It's in the price you see on the listing, not added at checkout, and we pass it through at cost. Clearance panel prices don't include it.

Panels by the pallet have their own listings, open to everyone: see Panel Pallets. For a bigger order, ask at the counter for a quote.

Yes. Bring your parts list, or what you want to run and for how long, and we'll go through it with you at the counter. Anything that depends on how your system is installed goes to Solar YYC's licensed electricians.

For closed-loop communication, both ends need the same protocol, usually CAN bus, sometimes RS485. Check the protocol on both datasheets and the inverter maker's battery compatibility list. Not sure? Ask us before you buy.

Read the mark on the label or the datasheet: it should come from a certification body accredited by the Standards Council of Canada, carry the Canadian identifier, and name the standard. Where a product page has a Datasheet button, you can check it before you buy.

UL 9540 is a listing for an energy storage system. UL 9540A is a fire test method; it produces a test report, not a listing.

Use Voc at the coldest temperature your site sees, not at 25 °C. Voc rises as the panel gets colder, and the string has to stay under the charge controller's maximum PV input voltage. You need four numbers from your own datasheets: the panel's Voc, its temperature coefficient of Voc, your site's lowest temperature, and the controller's maximum input.

Charging in the cold is what does the damage; using it in the cold is generally fine. Check two lines on your battery's datasheet: the charge temperature range, and whether the pack has its own heater. The winter lithium guide goes through both, battery by battery.

Inside the City of Calgary, solar and battery systems need an electrical permit and a licensed, registered contractor. Outside the city, the rules are set by your local authority; ask them before you build.

Look the shipment over before you sign. Photograph every side and any damage, and write the damage on the delivery receipt before the driver leaves: carriers only accept a claim for damage written on the receipt, so we can only replace what's noted there. Then contact us the same day: 587-287-9180 or hello@maplesolarsupply.ca. Damage you only find after unpacking, with the outside packaging intact: tell us within 3 business days, with photos, and keep the packaging. Shipping policy

Not working, or not as described: tell us within 30 calendar days and we replace or refund it, whatever the part. Damaged: tell us within 3 business days. Changed your mind: unopened parts within 30 days get a full refund, opened but unused parts a refund less 15%, panels included. Batteries, cut cable, cut rail, special orders, installed parts and clearance panels can't be returned for a change of mind. Returns policy

For the first 30 days, we do: tell us and we test it, then replace or refund it if it's faulty. After that, the maker's warranty covers it, and we help you troubleshoot and with the claim.
