Big Dog Solar Review

Big Dog Solar reviews: what customers say

The five positive reviews below praise courteous, hard-working installers and responsive, knowledgeable customer service. The five negative reviews describe door-to-door sellers who ignored a no-soliciting sign or reportedly claimed to work with the utility, a system left unpaired and miswired with slow permit closing, high winter bills and a report of harassment by a sales rep, and poor care after the sale. These are issues to ask about, not a measure of how often they happen. Ask Big Dog who closes the permits and handles service calls after payment.

How we picked these: the five newest 5-star and the five newest 1- or 2-star reviews with written text on Google and Trustpilot, as of October 2026 (200 reviews read, back to Sep 26, 2024). We found no Trustpilot page for Big Dog Solar on October 12, 2026. Each quote is one sentence, word for word. Picking the highest and lowest ratings shows the range of experiences; it is not a representative sample, and we did not verify what reviewers describe.

How much does Big Dog Solar cost?

Big Dog Solar does not publish a fixed system price on the pages we reviewed. It points buyers to an online quote tool that designs a system from satellite images. Ask for an itemized written quote showing the cash price, system size, equipment models and, for a lease or financed balance, the full amount you will pay with APR and fees. For state price ranges, see our solar panel cost guide; for how the plans compare, see loans, leases and PPAs.

Plans as listed on Big Dog Solar’s homepage and Boise page, read October 13, 2026. No lender or leasing partner is named.

Big Dog Solar does not name panel or inverter models in its page text. Its homepage shows REC and Tesla logos. Its battery backup page names two batteries: the aPower2 (15 kWh) and the Tesla Powerwall 3 (13.5 kWh). It also installs whole-home natural gas generators. Your written proposal should list the exact panel, inverter and battery models, the system size in kilowatts (kW) and the forecast yearly production in kilowatt-hours (kWh). The company says its customer service team works in Pocatello, Idaho, and it offers a page to verify a sales representative.

What does Big Dog Solar’s warranty cover?

Company-published terms from Big Dog Solar’s homepage payment section (read October 13, 2026), its battery backup page and the FAQ on its dealer partner page (read October 14, 2026). The dealer page is written for installer partners, not homeowners. It has no separate warranty page. Your signed agreement decides what applies.

Where does Big Dog Solar operate, and which licenses were checked?

Big Dog Solar’s service area page says it focuses mainly on Idaho, Utah, Colorado and Montana (read October 13, 2026). It lists towns around five hubs: Boise and Pocatello in Idaho, Helena in Montana, and Grand Junction and Windsor in Colorado. The Boise list also names Ontario and Nyssa, Oregon. No Utah hub or town list is given. The FAQ on its dealer partner page, written for installer partners, says it services “all of Southern Idaho, Northern Utah, Western Colorado and bits of Wyoming & Oregon” (read October 14, 2026). A listed town does not mean every address qualifies or that EcoGen can connect you with Big Dog Solar there.

Licenses

We have not checked Big Dog Solar’s licenses in a state registry yet, and its website does not list license numbers we could match. Check the license yourself under the exact business name on your contract. A license check confirms registration, not workmanship quality.
