Question 1

How much does a solar system cost in Puerto Rico?

Accepted Answer

A residential solar system in Puerto Rico starts at $13,000 and up, depending on your home's electricity consumption and the system size required or desired. The most popular systems start at 4 kW solar and 10 kWh battery, and for residential we've worked up to 25 kW solar and 64+ kWh. During the free consultation, we present a detailed analysis of the cost and projected savings over 7 years.

Question 2

How long does solar installation take in Puerto Rico?

Accepted Answer

The complete process from contract signing to your system producing energy takes between 1 and 3 weeks. This includes obtaining permits from OGPE (Office of Permit Management), interconnection approval with LUMA Energy, equipment delivery, and physical installation. The installation itself typically takes 1 to 2 days. We handle the entire permitting process for you — you don't have to do anything.

Question 3

How often should solar panels be cleaned?

Accepted Answer

We recommend maintenance and cleaning every 6 to 8 months for systems in interior and central Puerto Rico. For properties in coastal areas, the ideal frequency is every 4 to 6 months due to salt buildup and Saharan dust that reduce panel efficiency. Puerto Rico has unique environmental conditions that require specialized maintenance. A dirty panel can lose up to 25% of its efficiency, so regular maintenance protects your investment.

Question 4

Does the solar battery work during LUMA Energy outages?

Accepted Answer

Yes, solar systems with battery backup are specifically designed to provide energy independence during LUMA Energy outages. A standard battery system can provide up to 24 hours of electricity for essential home appliances. Our systems are configured to automatically disconnect from the grid when they detect an outage and reconnect when LUMA Energy restores service. This protects both your family and the LUMA technicians working on the lines.

Question 5

What warranties do you offer on solar systems?

Accepted Answer

The solar panels we install come with a 25-year manufacturer warranty covering both performance and manufacturing defects. Inverters and batteries have mostly local warranties, generally between 5 and 10 years. We also include a complimentary 3-month quality inspection to verify your system is operating at peak performance. An optional extended service plan is available for those who want additional coverage.
