Frequently Asked Questions

Mario Castillo Electric is a trusted name in the renewable electric and solar energy industries, and we pride ourselves on providing exceptional service to our clients. We understand that navigating the world of electric and solar services can be confusing, which is why we’ve compiled a list of common questions. View our resource below for homeowners and businesses.

Why should I switch to clean energy?

Solar energy reduces your electricity costs, increases your home’s value, and lowers your carbon footprint. It also provides long-term energy independence by protecting you against rising utility rates.

Can you service systems installed by another company?

Yes. We specialize in reactivating and servicing legacy or abandoned installs, ensuring they are brought back online safely and efficiently.

Do you offer upgrades to existing solar systems?

Absolutely. We can expand your system with additional panels, add battery storage, upgrade inverters, or integrate smart energy platforms such as Modbus, MQTT, or Home Assistant.

What maintenance is required for a solar system?

Solar panels are low-maintenance, but we recommend periodic system checks. Our services include monitoring performance, diagnosing issues, updating firmware, and ensuring wiring and inverters remain in top condition.

How can I monitor my system’s performance?

We can help you track production vs. consumption in real time. If Wi-Fi is lost or your system disconnects, our team can remotely diagnose and restore connection.

What does the installation process look like?

We handle everything from system design and inspections to final installation and activation of the system, with ongoing maintenance, troubleshooting and beyond. Installation is unique to the size of project but with Mario Castillo Electric you will know the status of the project every step of the way. 

What happens if my solar system stops working?

We offer full troubleshooting and repair services. From inverter resets and wiring inspections, our technicians can identify and fix the issue quickly.

Will I still have power if the grid goes down?

Standard solar systems shut off during outages for safety reasons. To maintain power during blackouts, we offer battery storage solutions that provide backup energy when you need it most.

Is financing available for solar projects?

Yes. We partner with trusted financing providers to make solar more affordable. Options include low-interest loans, payment plans, and incentives such as tax credits and rebates.

Which battery should I consider when selecting a solar battery?
