Sustainable Sourcing

Products and Suppliers

Products must:

  • Meet relevant standards eg. MCS, CE, G98 & G99 certification
  • Be of high quality and reliability with good warranty terms
  • Be supported by good suppliers & service
  • Be good value for money
  • Be energy efficient

Suppliers are chosen based on:

  • Our research
  • Our experiences
  • Recommendation
  • Their reputation
  • Their service
  • Good business & personal relationships
  • Their financial stability
  • Quality and reliability of products
  • Environmental credentials
  • Innovation
  • We choose the best equipment from the world’s leading manufacturers to ensure your success!

Offering an extensive range of the best products at competitive prices.

Sustainable Sourcing

We aim to use products from suppliers who manufacture ethically and with minimal environmental impact wherever possible.

Product Stewardship

  • Wind & Sun ensure that all products that we sell are safe and fit for purpose.
  • Wind & Sun try to ensure that all products we sell have no detrimental effects on the environment.

Embodied Energy from Production

Embodied energy is the energy used to produce something and then transport it

  • Many of our suppliers use renewable power in their processes.
  • Renewable energy equipment generates more energy over its lifetime than is used in its production.

Influencing Suppliers

To influence our suppliers to support sustainable practices, a questionnaire, asking about their policy on sustainability issues, will be sent out.

Fronius Inverters

The Fronius maxim “Sustainably designed, sustainably made”, means their products are not only created in an especially resource-friendly way but are also designed for superior durability and reparability.

With 100% assembly based in Austria they use 100% electrical energy on site from renewable sources with PV with total output of 2.3 MWp installed at Austrian locations. 81% of all energy consumption - including mobility and maintenance - comes from renewable sources.

With their own 6,070 m² PV systems, Fronius achieved an annual yield of over 588,400 kWh in 2019. This amount of energy would supply around 150 households for a whole year, or alternatively, 4 million km could be covered by an electric car.

REC Solar PV Panels

REC factory Singapore

REC panels have low carbon footprint, quick energy payback time and are easy to re-cycle at end of life.

The REC production facility in Singapore has ISO14001 certification and includes a large solar PV system for on-site energy generation, with around 3,000 kWp of rooftop solar PV installed, generating around 3,500 Mwh of clean solar energy per year.

Thanks to continuously implementing new measures, REC was able to reduce specific energy consumption since 2020 by 40% to 90MWh per MW of produced solar panels in 2022.

my-PV Heating Controllers

As a manufacturer of solar-electric building technology, when looking to build new premises it was clear to my-PV that they should implement their own philosophy of photovoltaic heat at the new location. The 100 kWp photovoltaic system, which is mounted on the roof and in the facade of the building, provides massive energy excess that can be optimally used with the thermal storage mass in the building.
