Solar Thermal Around The World (Part #1): Chile

Thursday, March 25th, 2010

Solar Thermal is common in first world countries such as Spain and Israel. And in the U.S., thanks to financial incentives and a growing desire for energy independence, the technology is increasingly widespread. Because basic Solar Thermal systems are relatively inexpensive and proven to reduce energy consumption, they’re popular not only in developed nations, but also in places with more limited financial resources.

In Chile, for example, a government project is currently bringing Solar Thermal to hundreds of shantytown residents near Santiago. Solar Thermal systems installed on new homes the government is building for these underprivileged people will provide financial savings of 62% for a family of four using 10.5 gallons of water per day at 115 degrees Fahrenheit. This project comes on the heels of legislation approved last year in Chile authorizing government subsidies of between 20 and 100 percent of the cost of Solar Thermal installations in new residential buildings.

Granted, the vast majority of Americans are far better off economically than the Chileans who will benefit from their government’s Solar Thermal program. But the desire to save money by reducing energy costs has strong appeal across all cultural, economic and national boundaries.

The installation cost of a Solar Thermal system is quite reasonable when you consider the long-term financial benefits. Sure, it may take a few years for the energy savings a new Solar Thermal system provides to equal the cost of installation. With a minimum 25-year lifespan though, these systems continue paying back long after they’ve paid for themselves. No matter what country you’re from, that is a sensible proposition.

Fermentation, Fire, And Water

Thursday, March 11th, 2010

Kegs 1“Fermentation may have been a greater discovery than fire” runs a quote by noted author David Rains Wallace. We here at SunWater Solar certainly agree, as would anyone who has ever successfully brewed a batch of ale, lager, stout or other type of beer.

California is well-known for producing fine beers. Brewing companies like Sierra Nevada, Anchor and Gordon Biersch turn out millions of bottles of brew every year from their facilities in California, while countless smaller breweries across the U.S. also add to the diversity of beers that drinkers can choose from.

A large percentage of beer is water, which is also a central part of the brewing process. Breweries need large quantities of water – hot water – to not only make beer, but also to rinse and clean the kegs, tanks and other equipment used to manufacture and ship the final product.

There is a simple elegance in the combination of water, heat and basic ingredients (yeast, sugar, grains, etc.) necessary to craft beer. Bringing the sun’s natural heat into the process by way of a solar hot water system adds to this elegance.

And for brewing companies, which are businesses after all, a solar thermal system can be a sound investment since these systems significantly reduce water-heating costs.  Breweries in Wisconsin, Oregon, and Montana have all turned to solar water heating for their brewery operations.

Water. Natural ingredients. Solar energy. Now that’s a discovery that’s easy to get excited about!

A Win-Win For Apartment Building Owners And Tenants

Friday, March 5th, 2010

Estabrook 5Most people have spent some stretch of time living in an apartment building. If you’ve ever rented an apartment, you know that noisy neighbors, shared laundry machines and crowded conditions can be downsides to apartment life. But having the freedom to move out as soon as a lease ends helps make such inconveniences worthwhile. And as a tenant, you also don’t have to worry about the large amounts of money required to keep an apartment building operational.

Unlike tenants, apartment building owners see their buildings as long-term investments, with long-term costs. Building owners, for example, must frequently pay the entire building’s monthly water-heating bill. Every time a tenant cooks a meal, does laundry or uses the bathroom, that’s money out of the building owner’s pocket! And the more people there are living in the building, the higher the owner’s costs.

Water-heating can account for a large percentage of an apartment building owner’s monthly energy bills. Solar thermal systems reduce energy bills, insulate owners from rising natural gas prices and help owners go green by using the sun’s energy, rather than electricity or fossil fuels, to heat the water used by tenants. A solar thermal system can produce 60% to 80% of an apartment building’s hot water load, and also help differentiate the property among environmentally conscious tenants.

For apartment building owners and tenants, solar thermal is a win-win!

Cool It Down- With Solar Thermal!

Monday, March 1st, 2010

ChillerSay the words “Solar Thermal” and readers of the SunWater blog may envision rows of Solar Thermal collectors providing low-cost hot water to homes and businesses. But what many people don’t know is that besides heating water and other fluids, Solar Thermal technology can also reduce air-conditioning and industrial cooling costs.

Solar cooling systems use concentrating solar collectors and absorption chillers to drive the cooling process for air conditioners and industrial cooling. So how exactly does such a system save money for building owners?

Electricity rates are often tiered, meaning that the more electricity a building uses during peak hours, the higher the rate charged for that electricity. Peak hours often occur on hot sunny days when the air conditioning load is highest. Installing a solar cooling system can result in big savings since the system reduces electricity use during peak hours. What’s more, the same concentrating solar collectors used for cooling can also be used to heat water for the facility.

Summer is coming, and if you’re looking to cut your cooling bills this year, give SunWater a call today to learn more about how you can cool it down with Solar Thermal!
