7 Things to Check Before You Buy Solar in Mexico
Solar is a 25-year purchase. Ten minutes of checking before you sign saves years of regret. Here's the list we'd use if we were the ones buying.
1. Gather 12 months of CFE bills
Your consumption history is the foundation of a correct system size. Anyone who quotes you without asking for it is guessing with your money.
2. Confirm who actually climbs the roof
Ask: who performs the installation, and who answers when something fails in year three? Our answer is public — installs are managed by Gus at Baja Electrician with his certified, insured crew, and our office on Blvd Popotla answers the phone 8am–4pm.
3. Ask for the warranty in writing — all three of them
A real quote separates panel production warranty (25 years), equipment/inverter warranty (10–15 years), and workmanship warranty on the installation itself. If the paper only mentions one number, keep asking.
4. Check the roof first, not last
Waterproofing, structure and orientation should be evaluated before the contract. Drilling into an unprepared concrete roof creates leaks that cost more than the panels.
5. Make interconnection someone's job
The CFE net metering contract is what turns sunshine into credit. Confirm the installer files it, tracks it, and doesn't call the system "done" until the bidirectional meter is spinning. It's included in every Solar 1 installation.
6. Match hardware to the coast
From Playas to Ensenada, ask specifically about salt-air certification and marine racking. Inland quotes reused on the coast fail early.
7. Think about outages now, not later
A grid-tied system alone shuts off when CFE goes down. If outages are your pain point, price battery backup in the original design — retrofits work, but integrating from day one is cleaner.
