Solar Panel Warranties for Residential

The two major components of a solar PV system are the modules and the inverter. Both technologies come with long-term manufacturers warranties and backed by StraightUp Solar’s 10-year workmanship warranty and 10-year production guarantee.

StraightUp Solar offers:

Our Full-time Service Team has You Covered

Beyond our warranties, we have a dedicated in-house Service department. Our experts are well qualified to keep your solar array up and running for the 25+ year lifespan on your system.

We stand by our system design calculations.

How it Works

Understanding how solar works can help you think about manufacturer’s warranties for the parts that make up your array. Use our interactive graphic to learn more about how solar works for your home.


1. Solar Array

The sun's rays hit your solar panels and generate
direct current electricity


2. Inverter

An inverter changes this direct current electricity
to alternating current and it's ready for use in
your home


3. Excess Solar Electricity

Anytime you produce more than you use, the
excess is shared with your utility


4. Net Metering Credits

In exchange, your utility gives you a credit to use
when the sun is down


5. Monitoring

You can even go online to track your solar
energy production


Solar Panels

Solar photovoltaic (PV) panels rest on your roof (or property for ground mounts) absorbing photons from the sun and releasing electrons to move through the modules to create electricity to your home. This reaction occurs with no moving parts and allows for a long life for your solar PV system. Based on in-field experience and rigorous manufacturer testing, you can be confident of these solar panels will perform well for decades.

Solar photovoltaic (PV) panels typically come with an industry standard 25-year warranty. This has significantly improved in recent years due to advances in panel technology. Every solar array we offer is Tier 1-rated for durability and efficiency. Solar panel selection is a part of our process to find the right fit based on the energy needs of your home. Our expert solar designers develop a system with consideration of the shade, heat, brightness, angle, direction, and other factors of your roof (or property for ground mounted systems) to ensure your system meets your desired energy goals.

Solar Inverters

Solar inverters–which connect your solar panels to your home–are a relatively simpler warranty discussion. While more complex than a solar panel because their electronics convert DC to AC electricity and sync with the grid, inverters still carry a relatively long warranty. For most grid-tied inverters the minimum warranty is 10 years, with some as long as 25 years (more common with microinverters). Some manufacturers allow the purchase of an extended warranty, from 10 to 20 years.

When the inverter warranty is less than the panel warranty, StraightUp Solar includes the replacement cost in your solar estimate. That way you won’t have to worry about the cost later.
