How to Select Solar Water Heaters
The majority of people know that the sun can be used to heat their household water with the help of a solar water heater, however what they don’t know it how to carefully select the right system for their specific needs.

Each solar water heater is made up of two main components, the collector, and the storage tank. However, it is the other components that can and often do vary greatly in both design and efficiency. The design of a solar water heater is classified as either passive or active and as direct (open loop) or indirect (closed loop).
Passive systems do not use pumps or controls to regulate or circulate the water through the system. Because of this, passive systems are more durable, reliable, and last longer lasting. In addition, they are also easier to maintain. They are also less expensive to operate than the active systems.
Active systems as you can guess do require the use pumps and controls to transfer the heated water from the collectors into the storage tanks. Because these systems have mechanical parts, and require electricity to operate, they are more expensive, and require routine maintenance.
Both of passive and active systems will require a conventional hot water heater for a backup system as both systems can meet approximately half of a entire household’s hot water needs depending on that household geographic area and water usage. In some households, a solar hot water system could supply a household’s entire hot water needs, but these instances are few.
Direct systems are not at all effective in climates where the temperatures fall to or below freezing. Indirect systems, however, are more effective simply because they utilize a form of antifreeze in the collectors which reduces the likelihood of freezing.
To help you select the right solar water heating system, please visit the Solar Rating & Certification Corporation website at: www.solar-rating.org The SRCC publishes performance ratings on solar water heating systems as well as individual solar collectors. These findings are the result of product testing by independent, third party laboratories.
In addition, every product that is certified by the SRCC will bear the SRCC label. However, to ensure that the product that you choose is the right system for your household and area, you have to do carefully comparison of the information provided by the SRCC. This will also guarantee your understanding of the products expected performance.
In addition, keep in mind that choosing the right solar water heater for your geographic area, household needs is only a small part, you also have to ensure that you select a system that is of proper size. Then the system has to be installed correctly as well as correctly maintained to ensure that your system provides you with the best performance.
How to Make a Solar Panel
Solar panels collect energy from the sun, and then convert the energy into electricity. Solar panels, especially the large PV (photovoltaic) systems are expensive.
One reason for their expense is that they the use invertors to convert DC (direct current) power into AC (alternating current) power. Some solar systems can be interfaced to a grid, which will permit the homeowner to selling excess electricity when they have it or purchase electricity when they don’t have enough stored.
What many people don’t know is that they could use solar panel kits to build their solar panels. The majority of these kits include all of the components required for setting the solar panel including: solar cells, soldering iron, solder, flux, and tabbing as well as detailed instructions on how to make assemble the solar panel.
For many of the kits, you only have to be able to read and follow the systematic instructions in order to construct the solar panels. You will be able to save a tremendous amount of money if you can build your own solar panels.
There are two basic types of solar panels available. The first type of panels, the absorber converts the sun’s energy into heat. The second type of solar panels converts the sun’s light into electricity.
These panels are known as photovoltaic panels or PV panels and are usually installed on the roof, facing the sun directly to receive the maximum amount of sunrays. PV panels use batteries to store electricity, and then supply a household its electricity needs.
Each solar panel consists of a collection of solar cells and each cell produces a small amount of electricity. However, collectively the cells produce enough electricity to supply an entire household’s power requirements.
In addition to choosing the type of panels you want, you can select from different types of tracking solar mounts. The first type is single-axis tracker, which is fixed at a vertical angle that is manually maneuvered to follow the path of the sun during seasonal changes. The second type is the dual-axis tracker, which automatically adjusts the vertical angle.
Solar panels that you build from kits are an effective way to reduce your energy bills, and help the environment all at the same time. Go online and research some of the many solar panel kits that are available.
