Thinking about solar but worried about scams? This beginner's guide walks you through the entire process — from understanding your electric bill to signing a safe contract — with no industry jargon.
Beginner's Guide: How to Go Solar Without Getting Scammed
Disclaimer: This article is informational, not legal or financial advice. Consult qualified professionals before making major home improvement decisions.
Overview
You want solar panels. You also want to avoid becoming one of the millions of homeowners who regret their solar purchase. These two goals should not be in conflict — but the residential solar industry has made them so.
On Reddit, one of the most common questions from newcomers is a variation of the same anxiety: "Looking to go solar but want to avoid the scams. What are some good beginner guides?" The fact that people feel they need scam-avoidance training just to buy a home improvement product tells you everything about the state of the industry.
This guide is for the person who knows nothing about solar but wants to learn — safely. No jargon. No sales pitches. Just a clear path from "I am curious about solar" to "I have panels on my roof and I did not get ripped off."
Step 1: Understand Your Electric Bill First
Before you talk to a single solar company, you need to understand what you are currently paying for electricity. This is the foundation of every calculation that follows.
What to Pull from Your Bill
Your average monthly usage in kilowatt-hours (kWh). Look at the last 12 months of bills. Add up the kWh used each month and divide by 12. This is your baseline.
Your actual rate per kWh. Divide the total dollar amount of your bill by the kWh used. Ignore the "rate schedule" printed on the bill — that is the base rate. Your real rate includes delivery charges, taxes, riders, and fees. The bottom-line number is what matters.
Your utility's net metering policy. Call your utility or check their website. Ask: "If I install solar, what do you pay me for excess power I send back to the grid?" The answer varies dramatically by state and utility. In some places, you get full retail credit. In others, you get a fraction of the retail rate. In the worst cases, you get almost nothing.
Whether your utility has time-of-use rates. If your electricity costs more during certain hours, solar production during those hours is more valuable. If you are not home during peak solar production hours, you may not capture that value.
The Simple Solar Suitability Test
Answer these three questions:
- Do you own your home? (Renters: solar is not for you right now.)
- Is your roof in good condition and less than 10 years old? (If you will need a new roof in 5 years, wait. Solar panels must be removed and reinstalled during a roof replacement — at significant cost.)
- Do you pay more than $100/month for electricity on average? (Below this, the payback period may be too long to justify solar.)
If all three are yes, solar is worth exploring further.
Step 2: Learn the Three Ways to Pay for Solar
There are only three ways to put solar panels on your home. Everything else — leases, PPAs, "free solar programs" — is a variation of these three.
Option A: Cash Purchase
You pay the full cost upfront. You own the panels. You claim the federal tax credit. You owe no monthly payments to anyone. When you sell your home, the panels go with it — no lease transfer, no lien complications.
Typical cost: $15,000 to $35,000 before the tax credit. Tax credit: 30% of the system cost through 2032 under the Inflation Reduction Act. Payback period: 6-10 years, depending on your electricity rates. Best for: Homeowners with savings who plan to stay in their home long-term.
This is the best option financially. It is also the only option that gives you full control.
Option B: Solar Loan
You borrow money to buy the panels. You own them. You claim the tax credit. You make monthly loan payments instead of a one-time cash outlay.
Monthly payment: Similar to or slightly less than your current electric bill, depending on the loan term and interest rate. Hidden cost: Dealer fees. Solar loans almost always include a fee of 20-35% added to the loan principal. A $25,000 system may actually cost $33,000. The salesperson calls this "the cost of the low APR." It is a fee. Ask for the dollar amount. Best for: Homeowners with good credit who want ownership but do not have cash.
Option C: Lease or PPA
You do not own the panels. A solar company installs them on your roof and you either pay a fixed monthly amount (lease) or pay for the electricity they produce (PPA). The company claims the tax credit. The contract typically runs 20-25 years with an annual rate escalator.
Monthly payment: Usually lower than your current electric bill in year one — but the escalator means it increases every year. Hidden cost: The contract places a lien on your property. When you try to sell your home, the buyer must qualify for and accept the contract — or you must buy it out, typically for $15,000 to $40,000. Best for: Almost nobody. In narrow circumstances — you cannot use the tax credit and cannot qualify for a loan — it may be the only option. But go in with eyes wide open.
The Simple Rule
If you can afford cash, pay cash. If you cannot, get a solar loan. Avoid leases and PPAs unless you have exhausted every other option and fully understand the escalator and the home sale implications.
Step 3: Get Multiple Quotes the Right Way
Do Not Respond to Door Knockers
The salesperson who shows up uninvited is being paid to close you, not to educate you. Any company that needs to knock on doors to find customers is spending money on sales commissions, not on quality equipment or installation. Let them knock. Do not open the door.
How to Find Companies to Quote
- EnergySage.com: A marketplace where installers compete for your business. You submit your information once and receive multiple quotes. The companies know they are competing, which improves pricing and transparency.
- Local referrals: Ask neighbors with solar panels who installed them and whether they would recommend the company.
- NABCEP directory: The North American Board of Certified Energy Practitioners maintains a searchable directory of certified installers at nabcep.org.
What to Ask Every Installer
Send these questions by email to every installer before you take a phone call:
- What is your cost per watt for a cash purchase of a [X] kW system?
- What specific panel make and model do you install?
- What inverter type and model?
- What is your workmanship warranty term?
- What is your contractor license number in my state?
- Do you employ your own installation crews or subcontract?
- Can you provide three local references from installations completed more than two years ago?
Installers who answer all seven questions clearly and promptly move to the next round. Installers who deflect, generalize, or refuse to provide specifics are eliminated.
Step 4: Understand the Contract Before You Sign
The Terms That Matter Most
Ignore the glossy brochure and the smiling stock photos. Focus on these five contract elements:
Total system cost in dollars. Not monthly payment. Not "savings over 25 years." The total cash price of the system. If you are financing, compare this to the cash price to identify hidden dealer fees.
Equipment specifications. Exact panel model, inverter model, and racking system. No generics.
Production guarantee. If the company promises the system will produce a certain number of kilowatt-hours per year, get the specific terms: what is the guarantee, how is underperformance measured, and what is the remedy?
Workmanship warranty. Covers installation defects. Minimum 5 years, preferably 10 or more. This is the warranty that protects you when the installer drills through your roof deck.
Cancellation terms. The contract should include a clear cancellation policy and the federally required three-day right of rescission for in-home sales.
The One Clause That Changes Everything
Look for language about a UCC-1 financing statement filing. This is a lien on your property. If the contract creates a lien and this was not proactively and clearly explained to you, the company was concealing material information. Do not sign.
Step 5: Know What Happens When You Sell
Assume you will sell your home within 10 years. Most homeowners do. Ask every installer:
"What happens to this agreement if I sell my home in year 5?"
- Cash purchase or solar loan: The panels are yours. They convey with the property. The buyer gets the panels and the remaining tax credit value (if any). This is clean.
- Lease or PPA: The contract must be transferred to the buyer. The buyer must qualify. The buyer's lender must accept the UCC lien. Many transactions fail at this stage.

FAQ
How much will solar actually save me?
It depends on your electricity rates, your roof's sun exposure, and how you pay for the system. A properly sized cash-purchased system in a high-rate market typically pays for itself in 6-10 years and then produces free electricity for another 15-20 years. A leased system with an escalator may produce minimal net savings over the full term. Get the math from an independent calculator like PVWatts (free from NREL at pvwatts.nrel.gov) — not from the installer's sales software.
What is the federal solar tax credit?
The Residential Clean Energy Credit allows you to claim 30% of your solar system cost as a federal tax credit through 2032. The credit drops to 26% in 2033 and 22% in 2034. You must own the system — leases and PPAs do not qualify. The credit is non-refundable, meaning it can reduce your tax liability to zero but will not generate a refund beyond what you owe.
Do solar panels work when the power goes out?
Not unless you have a battery. Grid-tied solar systems are required to shut down during outages for utility worker safety. If backup power during outages is important to you, you will need a battery system — which adds $8,000 to $15,000 to the total cost.
How long do solar panels last?
Panels degrade slowly, typically losing about 0.5% of output per year. After 25 years, most panels are still producing at 85-90% of their original output. The inverter will likely need replacement around year 12-15, at a cost of $1,500 to $3,000.
Is solar still worth it if I plan to move in 5 years?
With a cash purchase or loan, possibly — the panels may modestly increase your home's value. With a lease or PPA, almost certainly not — the contract becomes an obstacle to the sale that may wipe out any savings you captured during your ownership.
