# Contract clause: Output Warranty

From my client's 2014 California contract **Exhibit 2:**

**2 . LIMITED WARRANTIES**

**(c) Performance Warranties and Guaranty** (p.16)

> **B. (iv) Output Warranty**The System's electrical output during the first ten (10) years of the Lease Term shall not decrease by more than fifteen percent (15%). This output warranty is in addition to the Energy Production Guarantee in Section 2(c)(i) of this Exhibit 2 and you will be provided a refund check for underproduction as set forth in Section 2(c)(i).

**I do not understand this clause.  **

Section 2(c)(i) is the **Power Production Guarantee**, the **Guaranteed Production Schedule. **

This is a very poorly written contract.  There are other clauses after Section 2(c)(i) -- why didn't they specify which clause applies?

**Regardless, none of those clauses answer my questions:**

Define "during the first ten (10) years" (a monthly or annual production, the production in year 10?)  and "15%" of WHAT?  The first year guaranteed production?

We are near the end of year 10.  In 2018 we got 4 more panels after the BBB mediation due to underproduction as the system was not properly sized.

I need a sample calculation.
