Building Integrated Photovoltaics (BIPV) Explained

BIPV systems are incorporated into the building envelope, providing energy for the building while serving as weather protection, insulation, noise reduction and more.

PV systems are installed in modules. Two common types of modules are currently in use &#; thick-crystal products and thin-film products. Thick-crystal cells are made of crystalline silicon. They generate 10-12 watts per sq ft in full sunlight. Thin-film products are thin layers of PV material applied to a glass or metal substrate. These produce 4-5 watts per sq ft in full sunlight. While thin-film products have a lower output, they are less expensive.

When it comes to energy collection, building integrated photovoltaics works similarly to other PV systems. Photons from sunlight strike the semi-conductive materials of the BIPV. Some photons are absorbed and converted into energy. The absorbed photons dislodge atoms from the material, creating a negative charge and attracting them to the front of the surface. The imbalance creates an electrical current. A PV inverter converts energy to power buildings and homes.

The electricity may be stored for later use, may immediately be used for power or sent to the grid. Most building-integrated photovoltaics systems are integrated into the electrical grid, but some are independent and rely on other power sources, like batteries or generators, when solar power is unavailable.

Any structural building material that can generate solar electricity technically counts as BIPV. Here are the main examples of BIPV tech today:

Roofing

Probably the most talked-about type of BIPV technology is solar roofing. Also known as solar shingles or solar tiles, this is an alternative to traditional rooftop solar panels &#; instead of placing panels on top of your existing roof, you can replace your roof shingles or tiles with a dual-purpose photovoltaic roofing material that both provides shelter and generates electricity.

A solar roof has many potential advantages, but the technology is less mature than conventional solar panels. Mainly, the cells of solar roof products aren't as efficient as traditional monocrystalline or polycrystalline solar panels, and glaringly, the cost of a solar roof is typically much higher than a rooftop solar panel installation.

Transparent glaze

The sun hits more building surfaces than a roof, so why not take advantage of that space? While solar irradiance depends on geography, one or more sides of a building often have decent sun exposure. Solar windows (or solar glass) are a category of BIPV products that rely on solar glaze, ultra-thin solar cells that capture sunlight while maintaining transparency, like an ordinary window.

General building elements

We don't have a suitable category for other ways of integrating solar into structures, so we'll go with "general building elements." This can include solar awnings, building facades, or anything structural about a building's side that can be solar-ified. More often than rooftop solar installations, these solar-integrated building elements experiment using lightweight thin-film solar panels or organic solar cells.
