What warranties should a solar system come with?

When a solar and battery system is installed on your home, the paperwork that matters most years later is the warranty coverage. Homeowners often hear the word warranty used as if it were one single promise, but coverage actually comes in layers, and each layer comes from a different party. Confusing those layers is what leads to angry phone calls later, when something stops working and nobody is sure whose job it is to fix it. Apollo Home Power explains each layer for San Diego customers in the proposal, in writing, before signatures, and that habit of separating the layers up front is worth understanding before you sign anything.

The three layers of coverage

The first layer is the equipment warranty, which comes from the manufacturer of the panels, battery, and related hardware. If a component itself fails, the manufacturer's terms are what govern repair or replacement of that component. The second layer is the workmanship warranty, which comes from your installer. That layer covers the quality of the installation work itself: how the system was mounted, wired, and connected. The third layer is not a warranty in the same sense at all. It is the production expectations written into your contract, the stated expectations for what the system should produce.

Keeping those three layers separate in your mind changes the questions you ask. A question about a failed battery cell belongs to the equipment layer. A question about a roof penetration or a wiring issue belongs to the workmanship layer. A question about whether the system is producing what was projected belongs to the production expectations in the contract. When all three are blurred into one vague promise, every problem turns into an argument about what was meant.

Why the layers get confused

The confusion usually starts at the sales table, where coverage gets summarized in a single reassuring sentence. A homeowner hears that the system is covered and reasonably assumes that one party stands behind everything, for everything, indefinitely. In reality, the manufacturer, the installer, and the contract each stand behind a different slice of the project, and the length and conditions of each slice can differ. Apollo Home Power's approach is to explain each layer for San Diego customers in the proposal, in writing, before signatures, so the division of responsibility is settled while everyone is still comparing options, not after a failure.

There is also a practical reason to read the layers separately: they are how you compare proposals. Two quotes can look similar on price while offering very different workmanship coverage or very different production expectations. The written layers are where those differences live.

The battery side of the paperwork

For the battery part of a system, the equipment layer deserves a close read because the technology has its own measures of durability. Apollo works with safe LiFePO4 battery technology rated for over 8,000 charge cycles, and a figure like that is part of the equipment story: it describes how the battery itself is built to hold up over repeated charging and discharging. The workmanship layer still matters alongside it, because a durable battery installed poorly is not a durable system. And the support layer continues after installation, since Apollo describes real-time system monitoring and dedicated support as part of how customers are looked after once the system is running.

Apollo also handles SGIP rebate enrollment and demand response enrollment for customers, and connects homeowners with local battery installation experts and California clean energy rebate programs. Those services sit outside the warranty layers, but they belong in the same written proposal, because they affect what you pay and what you can expect.

What to ask before you sign

Before signing, ask to see each layer named separately: which equipment warranties apply and from which manufacturers, what the installer's workmanship warranty covers, and what production expectations are written into the contract. Ask what happens in practice when something fails: who do you call first, and how is responsibility handed from one layer to another? A company that answers those questions in writing, before signatures, is showing you how it will behave years from now.

Apollo describes its process as a quick eligibility check, an in-home assessment, installation, and ongoing support, and it offers an accurate quote within 3-5 days through its website form. The warranty conversation belongs inside that process, at the proposal stage, while the layers can still be compared line by line.

A solar system does not come with one warranty. It comes with equipment warranties from manufacturers, a workmanship warranty from your installer, and production expectations in your contract. Apollo Home Power explains each layer for San Diego customers in the proposal, in writing, before signatures.
