Heat From DIY Solar Thermal Panels


In this video I decided to make a solar heating panel with design features that will be compatible with sky cooling later on. Solar heating is a very efficient method of using solar energy, with the ability to absorb 900-1000w/m2 of heat from sunlight, compared to only 200-300w/m2 of electricity that could be generated from a similarly sized standard solar panel.

DIY solar air heater videos are a big hit on YouTube, with a couple of main staple ideas – recycled pop can solar collectors, downspout solar collectors, screen or sheet metal solar collectors.Watch the video from NightHawkInLight for more info:

Aside from large commercial installations, the most common application for solar air heaters seems to be supplemental heat for individual rooms, like an addition, a workshop, garage or any other small outbuilding.


For example, if you can get your hands on a piece of toughened glass of a certain size free of charge, it would make sense to build the panel around the dimensions of that glass.In order to increase the solar absorption of the solar collector, the pipework should be fixed to a metal sheet – copper would be best, but it would be expensive and heavy, therefore aluminium is usually used. This absorber plate acts as a heatsink absorbing energy from the sun’s rays.
