COMPARE THE COMPLETE PROPOSAL

What to establish about Panasonic

Panasonic states that it has discontinued its solar and storage product lines while continuing support for covered products. A new Panasonic quote therefore needs a careful explanation of equipment availability, warranty eligibility, replacement handling and who will provide service. Existing owners should preserve model numbers, registration and installer records.

CLARITY BEFORE COMMITMENT

Read the exact Qcells model document

The Q.TRON BLK M-G2+ family publishes up to 440 W and 22.5% efficiency. Those maximum figures are not a promise for every module sold under the Qcells name. The proposed model’s data sheet is the source for dimensions, rating and warranty.

CLARITY BEFORE COMMITMENT

Build a like-for-like comparison

Question: Which model and how many panels?; Why it changes the decision: Brand-level maximum ratings may not match the quote.. Question: What fits each usable roof plane?; Why it changes the decision: Module dimensions and setbacks affect the number of panels.. Question: What annual production is modeled?; Why it changes the decision: Shade, orientation and inverter limits affect energy output.. Question: Which warranties include labor?; Why it changes the decision: Equipment replacement and installation service are separate obligations.. Question: What is the full cash price?; Why it changes the decision: Financing or lease payments can obscure differences in scope..

CLARITY BEFORE COMMITMENT

Compare roof output rather than a single efficiency number

A more efficient module can help where usable roof area is limited. On another roof, the layout may fit a similar system using a different panel size. Ask to see the actual roof plan and annual energy estimate for each option. Use matching shading, weather and degradation assumptions when comparing projections. If an offer projects more energy from less capacity, ask which assumptions account for the difference.

CLARITY BEFORE COMMITMENT

Verify service and substitutions

Request the product warranty, performance warranty and installation warranty. Check who handles a claim, whether labor and shipping are covered, and which conditions or registration steps apply. Make equipment substitutions a written approval step. The replacement model should preserve the agreed scope or come with an explained change in price and performance. Keep the final equipment schedule with the permit and commissioning records.

VERIFY CURRENT PRODUCT INFORMATION

Review the manufacturer’s current documentation.

Product names, specifications, availability and warranty terms can change. Confirm the exact proposed model and controlling documents before making a decision.

RELATIONSHIP & PROJECT QUESTIONS

Know who is responsible for each part of the project.

Is All Star Solar Qcells, Axia or EnFin?

No. All Star Solar is an independent solar sales organization and authorized sales partner of Axia by Qcells. All Star Solar is not Qcells, Axia, EnFin, the equipment manufacturer or the installation contractor. The appropriately licensed installation contractor and all controlling product, warranty and program terms are identified in the final written proposal and agreements.

Who performs the installation?

Project fulfillment and installation are performed by the appropriately licensed contractor identified in the final written proposal and agreement. A service-area or product page does not represent a local All Star Solar installation office.

Are products, financing or savings guaranteed?

No. Equipment and program availability, approval, pricing, production, utility outcomes and savings are property- and applicant-specific. The final proposal, agreements and applicable warranties control.

Request a California solar-and-battery review.

No generic savings promise. Start with the actual bill, property and written program terms.
