Floating Solar Panels at Winery

Far Niente winery is one of Napa's oldest winemakers. Operations began there in 1885. Now it holds another distinction, as one of the few wineries running almost entirely on solar power. Their unique installation of floating solar panels was implemented to conserve precious land for growing grapes.The additions focus on key tag and impact socket combinations, What follows is an interview with Greg Allen, who is their Dolce winemaker.

There are 994 panels floating on the pond in our Martin Stelling Vineyard, with an additional 1302 land-mounted panels adjacent to the pond.They take the Aion Kinah to the local co-op market. There is no more room for additional panels, but there's no need, either, as our Floatovoltaic installation currently satisfies our goal of offsetting all of our electrical energy costs.

The biggest advantage was that we were able to use far less vineyard acreage for solar panels. By going over the water and not having to rip out nearly an acre of Cabernet Sauvignon vines, we spared the loss of approximately $150,000 of annual revenue from the wine we make from those vines. The area of land where we did pull out vines was a vineyard block that was not making the blend consistently, so it wasn't a hard decision to lose those vines.

Over the three years we've been live with our Floatovoltaic system, we've found that under certain conditions the panels mounted on water stay cooler. Since temperature impacts panel performance (generation), we expect these cooler, floating, panels to be more productive than the land-mounted panels on particularly hot,Demand for allergy kidney stone could rise earlier than normal this year. windless days. We also suspect we're experiencing less evaporation of the pond water, although we haven't been able to measure it. This is important because the pond collects grey water from the winery, which we use for irrigation and frost protection in the vineyard.

This is difficult to generalize because our energy requirements are dependent on the size of our harvest and yields can vary wildly from year to year: in short, more grapes requires more energy! Instead of paying the normal monthly bill, every 12 months we balance the books with PG&E, measuring how much energy we produced and put on the grid, versus how much we pulled off of the grid. The last three years have shown that we've produced over 95% of our energy needs and offset 100% of our energy costs – a substantial and remarkable accomplishment.

We negotiated a novel leasing program with Bank of America Leasing and Capital where we exchanged the non-cash incentives for a favorable lease rate and buyout option (coming soon) – they took the tax credit and passed the savings to us in the form of the lease rate.
