220 Knollwood Drive. Inset: Giulietta Ulloa

Carlos Guinand, chairman of the solar power developer Sonnedix Group, and his wife Maria Luisa sold their home in Key Biscayne for $8.5 million, property records show.

The 6,042-square-foot waterfront house at 220 Knollwood Drive sold for about $1,406 per square foot. Guinand was also previously the managing director of Editorial Arte, a South American publishing company. Records show the buyers are Jorge F. and Maria T. Lazo. Jorge Lazo is owner of First Medical International Corp., a medical equipment supplier.

The Lazos are quite familiar with the area. They sold their 9,000-square-foot waterfront mansion at 310 Harbor Drive, about 1.5 miles away from their new home, for $19 million last week.

The six-bedroom, two-story home hit the market a little less than a year ago, according to Redfin. It was listed for $9.3 million, meaning it sold for an 8.5 percent discount. Giulietta Ulloa, of EWM Realty International, was the listing agent. Ulloa could not immediately be reached for comment.

The house sits on nearly 15,000 square feet of land and was built in 2011. Features include high ceilings, impact windows, a covered terrace, a heated infinity pool and private boat dock on 100 linear feet of waterfront, according to the listing.

Earlier this year, Estrella Insurance founder Nicolas Estrella listed his Key Biscayne estate for $40 million, marking the fourth most expensive home for sale in Miami-Dade County, and the most expensive in Key Biscayne.

In 2016, Evan Metropoulos, the son of Hostess investor C. Dean Metropoulos, paid a combined $58.9 million for adjacent homes at 775 and 755 South Mashta Drive, which total 2.3 acres.
