Polysolar Limited

Polysolar Limited

PolySolar delivers Building Integrated Photovoltatic - BIPV solutions. Use our aesthetically-pleasing, solar PV, transparent and opaque panels for cladding, canopies, facades or curtain walling. Our BIPV solutions improve BREAM performance by 20%. Our solutions replace conventional building materials, for little additional installed cost. Your building then generates electricity, reduces its carbon footprint, and provides a better return on investment. Our standard BIPV solutions currently include solar barns, car-ports, & greenhouses. We design, project-manage and install bespoke BIPV solutions for commercial and domestic buildings. Alternatively, we can supply you our solar glass PV panels. We work alongside architects, specifiers, contractors, developers, fabricators, installers and electrical services companies.

Polysolar Building-Integrated Solar Photovoltaic Glass

Polysolar develops, designs, and project-manages Building Integrated Photovoltaic (BIPV) solutions.  We are an award-winning Cambridge (UK) based developer and producer of innovative low-cost solar photovoltaic glass for the BIPV market and are now one of the world's leading providers.

Our unique thin-film solar PV glass is the first truly transparent alternative for conventional architectural building materials, generating renewable energy and a return on investment.

We work with clients, architects, surveyors and throughout the construction industry to provide turnkey and bespoke integrated PV solutions.   Our products provide an exceptional finish to a building enabling environmental targets and planning regulations to be met. Indeed our contribution to BREEAM environmental assessment method can be sufficient to extend classification by a whole category. 

Polysolar was established in 2007 by CEO Hamish Watson for the development of next generation Photovoltaic solar materials.  A Technology Strategy Board grant with development partners Solvay chemicals and Pilkington glass gave rise to the worlds largest single cell organic photovoltaic (OPV).

As the R&D progressed, Polysolar develop, launched and certified an amorphous silicon transparent glass solar panel (PS-C series) alongside an opaque glazing unit (PS-A series). The product range is enhanced by an all black higher powered micromoprh unit (PS-D series).   Technical details on the product and technologies can be found here.  The company is further introducing a range of BIPV products that address different architectural requirements, including a new range of high performance transparent glazing panels, façade cladding panels and flexible roofing panels. 

Polysolar brings together all of the required elements of a construction project to give end clients the confidence and ability to call Polysolar their choice for building integrated PV projects.

Without requiring any additional space or resources Building Integrated Photovoltaic (BIPV) substitutes for conventional glazing and cladding materials whilst delivering multiple benefits in renewable power generation.

BIPV can be used in all parts of the building envelope, including façades, roofs and windows. the ratio of façade surface area to roof surface area increases with building height, in addition the available roof area is often reduced due to the installation of facilities which means that BIPV façades are of particular value in high density urban areas.

BIPV offers the opportunity to make micro-renewable energy generation cost-competitive with conventional fossil fuels. By substituting conventional construction materials for solar PV modules the additional installed cost of the PV energy generation energy is only marginal. Combined with the multi-functional benefits afforded by PV glass and its opportunity to reduce energy consumption BIPV represents the future of building design.


Photovoltaic systems are extremely environmentally friendly, since the amount of energy the generate is significantly higher than than the amount used in their manufacture. Today's CO2 emissions stem mostly from the construction and operation of buildings, BIPV solutions are helping to resolve this conflict by making sustainable and emission-free energy conversion possible at the point of use.

BIPV greatly assists in helping buildings to achieve environmental and sustainability targets such as BREEAM.

By producing renewable energy for the building itself BIPV saves the need for fossil fuels. The transparent nature of the panels ensures additional energy savings by allowing natural light into the building reducing lighting requirements. Polysolar panels average 30kgCO2/m2 savings per year.

The exceptional thermal properties of Polysolar's double/triple glazed units reduces heat loss and thus produces energy savings with U values <1.

The glare control achieved by Polysolar's variable transparency PV glass panels eliminates the need for additional shading.


BIPV is unique as a building material as it provides a return on investment. For marginal additional initial costs BIPV performs the same functions as well as, if not better, than standard cladding materials but also provides a return on investment in the form of free renewable electricity for the building making BIPV an attractive economic investment.

BIPV reduces the amount of electricity used within a building and saves on the cost of purchasing electricity from the mains leading to huge economic savings.

In addition to the money saved through producing renewable electricity on site there are additional incentives through guaranteed government subsidies and Feed-in Tariffs. Click here for more information.

Buildings are taxed based on the amount of Carbon used in their operation and construction, BIPV greatly reduces this amount and produces huge savings on the amount paid in Carbon-tax.

Aside from the aesthetic value afforded by BIPV it helps to showcase a company's green credentials giving a competitive market advantage.
