All About Solar Leasing

2009 December 3

Though financial incentives and rebates such as EEMs exist to make a solar system purchase more affordable, many households and businesses still cannot make the investment. In addition, the promise of future financial savings still may not be enough to make buying a photovoltaic (PV) array possible for the average consumer.

Enter solar lease programs.

Building-Integrated Photovoltaics (BIPVs)

2009 November 22
New technologies in photovoltaics (PVs) are making the appeal and application of these energy-generating devices less cumbersome and less unattractive than in years past. Today, solar cells can be made to be thin and even transparent, opening up a whole new world of possible installation options for those wishing to harness energy with their homes or commercial buildings.
These new solar applications are often classed together in a group known as building-integrated photovoltaics (BIPVs). What these BIPV alternatives have in common is that they essentially replace conventional building envelop materials with elements that integrate solar energy collectors. Most of these applications use some type of semi-transparent or totally transparent solar cell. These solar cells are less expensive to produce and more flexible in their installation alternatives.
BIPV can take many forms and be applied to many building surfaces, including:
Slanted roofs: Traditional solar panel arrays can be installed on pitched or slanted roofs, both commercial and residential, but a less-obtrusive solar collection method is solar shingles. Made to be installed flush with existing roofing materials (or to replace all shingles over the entire roof surface), these solar modules blend better with the exterior of the building. They are thin and often shaped like conventional shingles, connected together in a large solar array.
Flat roofs: A thin-film cell is integrated into flexible polymer roof membrane that is applied across the surface of flat roofs, usually on top of existing roofing products. Many are combined with cool roofs, which are white membranes that reduce solar heat gain and the building’s cooling energy requirements. These are lightweight, durable, and provide an added layer of protection for existing roofing materials.
Glazing: Transparent modules are made by applying a coating to the inner surface of a glass surface which then conducts the current out of the cell. This glass is then used in windows, skylights, clerestories, and other glazings throughout the building to both allow light to penetrate while collecting energy. Depending on the level of transparency, the solar film can also provide shading.
Facades: Interesting architectural elements can often be added to a building’s exterior to provide visual appeal and add another solar energy collecting surface. These can either be installed vertically along a building’s face, or horizontally as awnings to provide shade for windows, parking lots, or walkways, all while generating renewable energy.
By installing these building-integrated solar options, building and homeowners alike can generate renewable energy without detracting from the outward appearance of their buildings. Additionally, since these solar modules are often installed over existing building materials, they can provide extra protection to roofing, siding, and even paving by shielding against precipitation and other weathering elements.
Although this technology is more popular in Europe today, many buildings being constructed throughout the US are using BIPV in their design as a way to augment other sources of electrical power. But older buildings can also be retrofitted with BIPV concepts, making these buildings more efficient without having to tear them down. The possibilities are nearly endless with BIPV, and the energy saving potential enormous.

Developing Technologies in Solar

2008 December 29

One of the major drawbacks to conventional photovoltaics (PV) and solar thermal heaters is their high initial cost, a major limiting factor to many in the west, and certainly a non-starter for those in developing countries. The major hurdle to overcome with traditional solar technology is the expense of using silicon. This inorganic material, which is also used in things like computer chips, is the main component that makes solar cells work. Unfortunately, mining and then processing it can be quite costly, and it’s not something that can be done by the average consumer at home, either.

How Much Does a Thermal System Cost?

Solar water heating or solar thermal systems usually consist of several components, including thermal collectors, a storage tank, and a system of tubes or pipes in a circulation loop. Together, these pieces work to collect and absorb the sun’s heat energy to warm water for home use, pools, spas, and radiant in-floor heating.

How Much Does a PV System Cost?

Photovoltaics (PV), or solar panel systems, are made with a semiconductor material—usually crystalline silicon—which absorbs sunlight and converts it directly into energy. The cells are then connected together, often 40 at a time, into modules or panels, and those panels are then connected into arrays.

Why Solar? Types of Solar Thermal

2008 December 19

Solar Thermal

Solar thermal is a blanket term for any technology that harnesses solar radiant energy for practical applications. Solar thermal applications can provide domestic hot water, space conditioning, or even electricity. In the US, solar thermal technology is used mainly to generate domestic hot water, although space conditioning applications have gained ground in recent years.

Solar Photovoltaics

Sunlight can be converted into electricity using photovoltaics (PV), concentrating solar power (CSP), and various experimental technologies. PV has mainly been used to power small and medium-sized applications, from the calculator powered by a single solar cell to off-grid homes powered by a photovoltaic array.

The Tipping Point

The time to put global warming solutions into place is now.We can’t wait any longer. Scientists say we need to turn the corner on global warming within 10 years to prevent very dangerous impacts from becoming inevitable. Each year that passes without tackling global warming head-on makes the problem more difficult and expensive to solve. read more…
