Clean all around - solar hot water

Lately, there has been a lot of talk around the water cooler about renewable energy sources. This includes technologies based on natural elements, such as wind, the sun, the ocean and thermal energy from the earth itself. Engineers have always been driven to improve windmills, hydroelectric dams, or electricity-producing turbines driven by tidal power, while scientists eagerly research other resourceful and eco-friendly electricity producing possibilities.

Solar energy is probably the most widely used, and most cost-effective, green energy source in the world. Using photovoltaics, sunlight is harnessed and converted into electricity, which can be used immediately, or stored for later. At present, numerous solar energy technologies already exist and are being implemented throughout the entire world.

One of the most popular solar power applications is solar hot water. Many systems are so sophisticated they can, year-round, provide most of the hot water used in homes, and commercial or industrial building. It is also considered one of the most profitable solar technologies found on today’s alternative energy market.

Understanding the basic components of solar hot water is not an overwhelming task. The collectors are generally mounted on the rooftop, where they collect the sun’s heat to warm up the fluid that runs through them. The hot water is then channeled through pipes to a solar storage tank where it is stored until it is needed for warm water, hot tubs, pools and radiant heat. Since the storage tank is well insulated and remains hot at all times, the solar hot water system works even after the sun goes down.

The benefits of a solar hot water system include:
• Free energy from the sun!
• Power bills will be substantially reduced
• Helping the environment and reducing the usage of non-renewable carbon based fuels
• Government tax rebates and incentives when switching from electric water heater to solar ones. Rebates vary in amount depending on the type of system that is being replaced.
• Providing up to 90 % of your hot water needs from the sun.
• Minimal maintenance required
• Suitable everywhere from harsh desert land to cold areas, where solar hot water is also used for snowmelt on sidewalks and driveways
• Affordable prices and financing may be available.

There are several distinct solar hot water systems available to the public. To find out which package suits your hot water consumption needs best, and is the most suited for your location, you should consult a dedicated specialist, such as the Melbourne-based company Solar Flow. They can calculate exactly the size tank and amount of collectors you need, and also know the best installation site on your roof. Indeed, what works for your neighbor, may not be the most efficient solution for you.

Solar and hot water energy systems have come a long way since they were first invented. In recent years, purchase prices have been slashed and the technology has become more advanced. A higher efficiency level means that you will get a quicker payback on your investment. Add government and manufacturer incentives and the fact that you will help stop climate change, and you have all the reasons why you should consider a ‘clean’ switch to solar hot water!
