Short answer. Solidarity by itself does not make the obligation indivisible. Article 1210 states that solidarity does not of itself imply indivisibility, so a solidary debt for a sum of money can still be paid in installments or partial payments; solidarity only affects who can be made to answer for the whole amount, not whether the debt can be divided into parts.
What the law says
Nor does solidarity of itself imply indivisibility.

Two separate legal questions
Solidarity answers the question of who can be sued for the full obligation, letting the creditor collect the entire debt from any one solidary debtor. Divisibility answers a completely different question, namely whether the obligation itself can be broken up into partial performances. Article 1210 keeps these two concepts from being confused with each other, and treats them as running on independent tracks that happen to intersect only when the parties or the nature of the obligation say so.
Why the debt can still be split
A sum of money owed by several solidary debtors remains, by its nature, capable of being paid in parts, such as through staggered or partial payments accepted by the creditor. Being solidarily bound only changes the pool of people the creditor may pursue for the outstanding balance; it does not transform an inherently divisible sum into something that must be paid in one lump.
The reverse principle, found in the same article, is equally true: an obligation being indivisible does not automatically make the debtors solidarily liable for it either, since one describes the nature of the object owed and the other describes how many people can be pursued for the whole.
Why this distinction matters
Debtors sometimes assume that being solidary means the whole debt is locked into a single all-or-nothing payment, which can lead to disputes over whether partial payments are even valid or whether a creditor who accepts one has somehow waived the solidary character of the loan. Recognizing that solidarity and indivisibility are independent concepts clarifies that partial payment arrangements remain possible even while full solidary liability for any unpaid balance continues, and it prevents either side from misreading one feature of the obligation as automatically dictating the other. A creditor who agrees to accept installments from one solidary debtor does not thereby lose the right to later demand the remaining balance in full from any of the other solidary debtors, since that right flows from the solidary tie itself and not from how the payments happened to be scheduled.
