Solar Basics

What is solar insolation? The amount of electromagnetic energy (solar radiation) incident on the surface of the earth. Basically that means how much sunlight is shining down on us. Why is knowing the insolation level useful? By knowing the insolation levels of a particular region we can determine the size of solar collector that is required. An area with poor insolation levels will need a larger collector than an area with high insolation levels. Once you know your regions insolation level you c...

What is Solar Collector? A solar thermal collector collects heat by absorbing sunlight. The term solar collector commonly refers to a device for solar hot water heating, but may refer to large power generating installations such as solar parabolic troughs and solar towers or non water heating devices such as solar air heaters. Solar thermal collectors are either non-concentrating or concentrating. In non-concentrating collectors, the aperture area (i.e., the area that receives the solar radiatio...

Solar water heating collectors capture and retain heat from the sun and transfer this heat to a liquid. Solar thermal heat is trapped using the greenhouse effect, in this case is the ability of a reflective surface to transmit short wave radiation and reflect long wave radiation. Heat and infrared radiation (IR) are produced when short wave radiation light hits a collectors absorber, which is then trapped inside the collector. Fluid, usually water, in contact with the absorber collects the trapp...

Solar hot water is appropriate for nearly every household, north or south. Of course, access to good sunlight is requisite, but most people have enough of it. The first step is making sure. If you have a roof that you are sure gets sunlight for a few hours a day, even in the winter, then the next step is to survey the site with a tool like the Solar Pathfinder. Most professional solar companies have a siting tool, or they can sometimes be borrowed from a local energy agency. But if you have dawn...

Using solar hot water is easily integrated into most peoples lifestyles. Once a system is installed and commissioned, it rarely takes any maintenance at all. The three main uses for SHW are: Domestic hot water is perhaps the best known of solar water heating applications. Nearly every home uses hot water every day, with the typical. household being around 50-120L per person per day. This covers showers, dish washing, and clothes washing. Hot water is stored in a tank for when it is needed. An en...

Estimating the Cost and Energy Efficiency of a Solar Water Heater Solar water heaters are more efficient the gas or electric heaters. Solar water heating systems usually cost more to purchase and install than conventional water heating systems. However, a solar water heater can usually save you money in the long run. How much money you save depends on the following: The amount of hot water you use Your systems performance Your geographic location and solar resource Available financing and incent...
