Four solar quotes. Which one actually fits your home?

What numbers should I compare in solar bids?

• Ask for panel quantity and model, system size and inverter details.
• Check which roof planes or other locations are included.
• Ask what shading and electricity-use assumptions drive the production estimate.
• Identify any roof, trenching, electrical or utility work outside the quoted scope.

If one design is larger, it may have a different purpose or production estimate. Ask the installer to explain the difference before comparing price per watt. Keep battery and other add-on costs separate when using that comparison.

What will the battery actually power?

Name the equipment you want available during an outage and ask for a written description of the proposed backup arrangement. Whole-home language can leave questions about simultaneous loads, high-demand appliances and how long stored energy lasts.

The installer should evaluate the design for your home. A utility incentive is not a promise that every circuit will work during an outage.

Is that the cash price, the financed price or the price after incentives?

Ask for two clear figures: the installed cash price before incentives and the complete financed offer. Request the loan disclosures, fees, term and any payment changes tied to an assumed future lump-sum payment. For a lease or power-purchase agreement, clarify ownership, escalators and transfer terms.

The IRS clean-energy credit page says the homeowner credit is unavailable for property placed in service after December 31, 2025. Do not use an old 30% credit assumption to judge a new 2026 installation.

Four offers. Start with the same numbers.

Illustrative example: These fictional figures explain the comparison. They are not customer offers, local market prices, advertised loan terms or promised savings.

A is $18,000 ÷ 6,000 watts = $3.00 per watt. B has the lower unit price but costs $3,600 more overall. That does not show which design meets your needs or which will deliver more useful energy for your household.

Don’t divide a battery bundle by the panel watts.

C includes a different purchase. Ask for separate installed solar and battery prices, then compare usable storage, power and supported circuits. D has a higher solar unit price than A, but the missing electrical work still needs a contractor’s assessment and price. None of these totals proves who is the best installer.

A lower payment is a different comparison.

Request the financed price and loan terms separately. Keep projected savings and incentives out of the installed cash-price column. Read our cash-versus-financed pricing guide if a monthly payment is doing most of the selling.

Please show the installed cash price before incentives, solar DC size, expected annual production and separate battery cost. Send financing terms separately. What work is excluded, and which assumptions drive the savings estimate?

Check the programs for your utility.

Start with Oregon solar and storage incentives. Pacific Power customers considering grid-connected battery participation can also read the Wattsmart Battery guide. Ashland Electric has a separate municipal path.

Have every contractor show incentives in the same format: program, expected amount, eligibility, reservation status and payment recipient. Do not add advertised maximums together without confirming compatibility.

Who helps if the system needs attention later?

• Who handles monitoring issues, warranty service and troubleshooting?
• What is included if a component fails, including labor and travel?
• Who coordinates interconnection and permission to operate?
• What would roof work or a home sale mean for the agreement?

Use the fair-price checklist alongside the technical explanation. We can coordinate free written bids; optional Full Advocacy helps compare and clarify the proposals and negotiate the final offer.

Ask what makes the savings forecast work.

Have installers use the same electricity history and explain roof layout, shading, projected production and the utility rates behind their forecast. A larger array does not automatically fit your usage better. The Department of Energy’s solar guide recommends a custom production estimate and considering roof suitability and condition.

For Southern Oregon, confirm the utility shown on your bill. An Ashland Electric customer should not accept assumptions copied from a Pacific Power proposal without checking them. Ask which export rules and rates were used and when they were checked.

Separate what is promised in the contract from what is modeled. Ask how changes in use, rates or equipment performance would affect the forecast. A sales estimate is not automatically a savings guarantee.

Ask for a stronger offer on the system you actually want.

Once you understand the design, ask whether the installer can improve the price or included scope. Keep panels, inverters, battery equipment and electrical work named in the revised offer. Removing a battery or shrinking the system is a design change, not simply a discount.

Need more options? We coordinate solar installation bids in Southern Oregon. If backup power is the priority, start with battery backup bid coordination. Optional $499 Full Advocacy adds detailed comparison, our written recommendation and one final negotiation round on scope and price.

One more question before you decide.

Does solar require an electrical panel upgrade?

Sometimes it does. Sometimes an approved design can use the equipment you already have. Before you accept an upgrade or a quote that leaves it out, ask the installer to explain the electrical work your home actually needs.
