Dow Chemicals buy Nuvosun Materials giant Dow Chemicals has bought the entire equity stake in CIGs solar startup Nuvosun to bolster its solar shingles line up. Note Dow has made huge plans for its solar shingles product line, though the company has not managed to actualize those plans till date. The company has only now […]

We would like to incorporate BIPV solar tiles or roofing when we build – so we are trying to find out a this point what products are now available in Australia and what our choices would be and the range of prices each would be in …just to give us a starting point as we begin to pull all the ideas together ?

We’d really appreciate any information you can send our way that would help us achieving this – the brand/type of BIVP we can use, the best inverter and battery you’d recommend – obviously it will depend on where we are and how much sun our roof will get – but we plan to make it as much as is possible as we’d like to be able create 100% of our power needs or if not at least 80 % . At present as a guide my household uses approx 10.7 khw of power a day – so that will give you an idea of how many solar tiles we’d need perhaps …if the sun was at its optimum ? We hope to be building on a reasonably sunny block between Ferntree Gully and Belgrave on the high side near bushland …beginning in a couple of months or so

BIPV is the acronym for Building Integrated Photovoltaics which means the integration of photovoltaic materials into building structures such as roofs,windows and facades.It not only replaces the building supplies but also generate electricity creating a killer green product.This is one of the fastest growing segment in the solar industry and it has been estimated that almost 6-7% of the solar industry is made of BIPV products.A wide variety of technologies and products are being used in creating BIPV products.Though a large number of big solar panel manufactures like Suntech,Yingli,Canadian Solar have come out with BIPV Panels and Products,the segment has not become as big mainly because of higher costs vis a vis the standard crystalline solar systems.There are also specialized BIPV suppliers such as Ascent Solar and Konarka whose products are more suited to the BIPV Industry than the normal module industry.Some of these suppliers have no option as their technology is no longer competitive with the Chinese solar panel producers.Solyndra had a niche product which could be used in rooftops with ease of installation and low weight.However the high costs drove it to bankruptcy.The next leg up to the BIPV industry should come up with more BIPV products from the Major Solar Companies and as cost of solar silicon decline further with scale and innovation

Solar Shingles are niche solar products meant for use on roofs of houses.There are not a lot of manufacturers of solar shingles as they are a new product and more difficult to install than standard silicon solar panels.Solar Shingles are manufactured by mainly American companies like Dow,Energy Conversion Devices.Their high costs and lack of easy availability has meant that solar shingles have not really caught the imagination of the customers.Also Solar Shingles do not get any added subsidy from the government vis a vis Solar Panels.Thus the higher prices of electricity generated from solar shingles means that they have become a poorer cousin of the mainstream Solar Panels.Also Solar Integrators are more accustomed to buying and installing solar panels which makes it even more difficult to push the sale of solar shingles.

Solar Roofs are a niche area but is growing in popularity with the entry of more and more companies selling products tailormade for this area.What are Solar Roofs exactly – does it mean a Roof with Solar Panels installed on it or something else.Solar Roofs are not roofs where solar electricity is generated by putting in solar mounting/racking systems and mainstream solar panels,rather they are roofs where specialized solar products called solar shingles are installed.Solar Roofs can also mean a roof where Building Integrated Photovoltaic products are installed.Some companies make BIPV products like flexible solar panels or organic/dye solar cell panels ( these are niche companies).

Investing in Green stocksĀ  is fraught with a lot of risk due to the following factors The demand and supply can fluctuate a lot as the industry is new and largely dependent on government subsidies Technological innovations can make the business models off companies redundant Unlike Dotcoms,green investments are capital intensive which makes it difficult […]
