The 30% Rule: When It is Worth Repairing vs Replacing
Ozora Soluções explains everything about the 30% repair rule based on more than 14 years of experience in repairing solar inverters and industrial drives in São Paulo.
What you need to know about the 30% repair rule
Understanding the 30% repair rule is key to making the right decision: repair, replace, or prevent future issues. The solar inverter is the most critical component of the photovoltaic system — when it stops, all generation ceases.
Correct diagnosis — the most important step
The most common mistake is making decisions without proper technical diagnosis. Buying new equipment when the fault was simple and cheap to repair is a waste that we frequently see in the lab.
Ozora provides a free diagnosis with a technical report within 24 hours. The report identifies the root cause, lists the components to be replaced, and presents the estimate before any decision is made.
The 30% Rule
If the repair cost is less than 30% of the value of equivalent new equipment, repairing is always the economically correct decision. In practice, most repairs at Ozora cost between 10% and 25% of the price of a new unit.
Preventive maintenance
The best way to avoid problems is through annual preventive maintenance: internal cleaning, capacitor checks, thermal paste renewal, sensor and relay testing, and firmware updates when available.
