June 14 (Reuters) - Shares in Spain's Solaria jumped by as much as 10% on Friday after a Bloomberg report saying that the solar developer had received unsolicited takeover approaches.

Solaria declined to comment.

At 2:12 p.m. (1212 GMT) the shares were trading 8.04% higher on the day at 12.36 euros in Madrid, giving it a market value of over 1.5 billion euros.

Bloomberg cited unidentified people with knowledge of the matter as saying the company had in recent months rebuffed interest from potential buyers because their price was too low, and it was not immediately clear if they had walked away or if Solaria was weighing options.

The stock has dropped by more than 30% since the start of the year dragged down by lower electricity prices, making it one the weakest performers on the Spanish blue chip index Ibex alongside drugmaker Grifols.
