Hiring a solar installer is one of those home improvement jobs where a bad call costs you for decades. Most people grab the lowest quote and regret it. Here's how to actually get it right.
Factors That Affect Cost
Your roof matters more than anything. A simple south-facing asphalt roof with no shade gets the cheapest install. Complex roofs with multiple angles, skylights, or old tiles bump the price by thousands. Local labor rates and permit fees vary wildly between towns, even counties. Panel brand and efficiency also shift the number — premium panels cost more upfront but produce more per square foot. Battery storage? Add five figures. Don't let a sales rep gloss over these details.
Getting Accurate Quotes
Ask for an itemized proposal. They should break down equipment costs, labor, permits, and any subcontracted work. Get at least three bids from actual companies, not national brokers. Look at the fine print on production guarantees — some companies promise a number they can't deliver. Ask what happens if your roof needs repairs mid-install. A good quote includes a site visit, not a satellite image guess. Cash price vs. loan price differs a lot; push them to show both.
Hidden Costs to Watch For
Permit delays can stretch a two-day job into three weeks, and some installers charge you for the waiting time. If your main electrical panel is old, you might need a costly upgrade to fit the new system. Trenching for ground mounts or running conduit through finished walls adds real money. Watch for “we’ll handle all rebates” that bury administrative fees. Also ask: if the city wants extra structural bracing, who pays? Read the contract for surprise mobilization or travel fees.
When to Prioritize Quality Over Price
You want the cheapest price until something leaks. A company with a ten-year parts warranty and a twenty-year workmanship guarantee is worth paying extra. Look for installers who have been in business at least five years and have local crews, not gig workers from two states away. Check their license and insurance directly — don't take a screenshot. If the bid is way under everyone else, they're probably cutting corners on wiring or racking. You don't save money when your roof rots.
