FAQ's

The strongest code available is the one listed at the top of this page, since offers rotate often. Compare the listed codes against your cart total before checkout to see which saves the most.
Active offers are collected on this page and refreshed regularly, so the current list is your best starting point. Availability can change without notice, so apply a code early in the checkout process.
Add your solar panels, batteries, or kit to the cart, then enter the code in the discount field on the checkout page. Confirm the reduction appears in your order summary before you submit payment.
Most codes carry an expiration date shown in the terms alongside each offer. Check that date on this page before you build a large order, since expired codes are usually rejected at checkout.
First confirm the code is still listed here and that your cart meets any stated requirement. If it still fails, try a different code from this page or reach out to the store's support team.
Some offers apply only above a certain cart total, and that threshold is normally stated with the code. Read the terms on this page first, especially if you are buying smaller accessories.
Shoppers typically find that only one code applies per order, though the terms with each offer are the final word. Test your preferred code at checkout and keep the one with the larger reduction.
New-customer offers appear from time to time and are listed here when available. If nothing is showing, sign up for the store's email list to hear about welcome promotions.
There is no student or military program confirmed in the store's published information. Shoppers in those groups should check this page for general codes and watch for seasonal promotions instead.
The store has previously run seasonal events such as a Summer Sale and Solar Upgrade Sale, so major holiday promotions are likely. Check this page in late November for any Black Friday or Cyber Monday codes.
Discount codes generally do not combine with items already reduced, and the terms with each code confirm this. If a code is refused on a sale item, try it on a regularly priced product instead.
Savings vary by offer, and no fixed percentage applies across the store. The reliable approach is to compare every code on this page against your cart total before completing checkout.
Large kits are often excluded from percentage codes because of their higher value, so check the terms carefully. If a sitewide code is refused, ask the store whether a kit-specific promotion exists.
Batteries are a common target for storewide codes, though exclusions do appear on premium items. Apply the code in your cart and confirm the discount lands before paying.
Bifacial panels from 50W up to 450W are among the store's core listings and frequently appear in promotional events. Compare the code discount against the listed panel price to judge the real value.
Charge controllers in 15A, 40A, and 60A sizes are accessory items that often qualify for storewide offers. Check the terms with each code, since accessory exclusions are sometimes applied.
Flexible panels and the 110W and 220W N-Type portable panels sit in the same catalog as the rigid range. Any storewide code usually covers them, so test it in the cart before checkout.
Wiring accessories such as the 20FT 10AWG extension cable and Y branch connectors are low-cost add-ons. A minimum order threshold may apply, so pair them with a larger purchase to qualify.
The store advertises US local shipping with free shipping on orders over $20 and delivery in 3 to 8 business days. A discount code lowers your subtotal, so confirm you still clear the free shipping threshold.
The store advertises a 30-day easy returns window along with a warranty on its products. Keep original packaging for panels and batteries, and confirm the specific terms before starting a return.
The catalog includes used panels listed as excellent condition, such as the 200W N-Type bifacial models. Discount codes may not apply to renewed stock, so verify the terms before ordering.
Yes, the range includes a 2.4W panel for Ring cameras plus 7.5W to 30W 12V battery maintainers and trickle chargers. These small items suit a storewide code, but watch any minimum order requirement.
