2017solar.com - If you wish to construct a Solar Window Heater Collector Panel, there are various concepts you will need to know. This text will go through the fundamentals to allow them to assist you design the perfect photo voltaic power system ever.
These concepts, primary as they seem, are literally quite important. It's because each PV panel and photo voltaic heater design revolves around them, no matter how complicated they are.
1. Light transmission. Light transmission is essential when you are choosing a canopy in your PV panel frame. Clearly, when extra light passes via, photo voltaic panels and photo voltaic heaters change into extra efficient.
2. Light absorption. When light is absorbed, it's often converted into heat energy. In some circumstances it's converted into electricity. Good photo voltaic absorption is crucial for Solar Window Heater Collector Panel. The extra radiation you'll be able to absorb, the better your heater works.
Nevertheless this idea is not confined to heaters. If photovoltaic cells are too reflective, they find yourself throwing again most of the photo voltaic power they receive. Thus engineers coat their semiconductors with an anti-reflection substance to forestall reflection.
3. Scattering. Mild is scattered when particles get in the way. This happens on a foggy day or when it rains. We won't control these situations. But we will take away the dust that choose PV panels. We will additionally select materials that discourage dust from settling. Alternatively, we will apply completely different coatings on the panel to attain this effect.
4. Reflection. As discussed, reflection lowers the efficiency of many photo voltaic power systems. Nevertheless it turns into useful once we are talking about photo voltaic concentrators. These machine reflect light from many angles and focus them onto a specific spot or area.
This is like a magnifying glass that concentrates light onto a small spot. With this power (gathered from the solar), we will use it for heating or cooking.
5. Heat conduction. Heat affects the performance of photo voltaic panels and photo voltaic heaters. Thus if we know how completely different materials conduct heat, we will channel heat effectively in direction of where we would like it to be. For example, photo voltaic panels change into less efficient when it gets too hot. Thus if we will conduct heat away from the panels, we will preserve its efficiency.
6. Convection. The reason why we don't set up photo voltaic panels too near to the roof is because we would like air to circulate freely between them. When convection occurs, extra heat is faraway from the photo voltaic panel array and this helps to decrease its temperature.
7. Radiation. There is not a lot you can help in terms of radiated heat affecting the performance of your photo voltaic panels. All you are able to do is make your photo voltaic panel body reflective. Less radiated heat is absorbed when you use reflective surfaces.
