A Chula Vista building will be the first in the city to power up exclusively on solar panels Thursday.

The Gateway Center on H Street in Downtown Chula Vista is the first commercial building to make the leap to solar energy.

The move is a part of the Property Assessed Clean Energy (PACE) program, which enables qualified residential and commercial property owners to make water and energy upgrades to their buildings.

Those costs are then repaid through saving on their property taxes. Since last year, 57 projects were completed or in the process of being completed.

The five story building installed 1,054 solar panels that will generate 344.6 kilowatts of energy for the structure.

Thursday will mark the ceremonial switching-on of the solar panels. Chula Vista Mayor Mary Casillas Salas, Mountain West Properties President Jim Pieri and Ygrene Energy Fund National Sales Director David Kelly are expected to attend.

Chula Vista is partnering with Ygrene Energy Fund to fund the upgrade.
