Photovoltaic, Solar Thermal & Passive Solar Photovoltaic

Solar Panel Installer Milwaukee BuilderSolar panels (mounted to a roof or tracking system) produce electricity. Roof mounted systems have few moving parts and can last 40 years or more. They function by using crystalline silicon in series that react to the heat energy (photons) of the sun to generate DC electricity. Solar Panel Installer Milwaukee BuilderThat electricity is converted to AC by an inverter and put into the electrical grid or it can be left DC and stored in batteries. PEA Builders mounts a double meter socket on most every home, so it is ready for a future solar install. Most utilities allow you to sell the extra electricity back into the grid, sometimes at a higher rate.

Solar Thermal

Solar Panel Installer Milwaukee BuilderThe large bubbled collectors of the late 70’s are gone. The new solar thermal collectors are much more sleek and resemble photovoltaic panels. There are essentially two different kinds that we use for residential applications. Flat plate collectors and evacuated tubes. We prefer the Flat plate collectors, which are much better suited to residential installs and cost less. With a properly sized system, 80% or more of domestic hot water and heating needs can be met. Solar Panel Installer Milwaukee BuilderA glycol mixture of water runs thru a series of copper tubes directly absorbing heat from the sun and transferring it to a holding tank for use as heat or hot water.

Passive Solar

Passive Solar Milwaukee BuilderMany different techniques for collecting passive solar heat can be accomplished in residential use. Proper orientation is first and foremost. The best orientation is to place the main living areas along the long axis within 15 degrees of South. The house can then be tuned to act as a solar collector with either “Direct” or “Indirect” passive solar.

Passive Solar Milwaukee Builder-Isolated solar gain can be accomplished with attached sunrooms that act like micro-climates collecting heat that can then be circulated into the main living area mechanically or through natural convection.

Passive Solar Milwaukee Builder-Direct solar gain draws the suns heat in through “high solar heat gain” windows and distributes that energy into a room to heat the air. Or onto a concrete floor sized to act as a collector (thermal mass) for collecting and storing heat.
Passive Solar Milwaukee BuilderIt is critical that windows, shading and thermal mass all be sized correctly to avoid overheating or overshading.
