This calculator is identical to the TI-30Xa Solar introduced in the year 1996. The main difference is the marketing concept.
The housing is made of recycled plastic and together with the
solar cells instead of batteries this allowed Texas Instruments Germany to use
the "Umweltzeichen" sign.
Consumers in Germany call it the "Blue Angel". Its official name is "Umweltzeichen" (Environmental Label or the "Eco-Mark"). What they are referring to is a special logo, which has for two decades now been a symbol for products with positive environmental features on the German market. Well over 3,800 products now bear the mark. This success is proof of the increased environmental awareness both of producers and of consumers. Because the Environmental label is an entirely voluntary labelling of a product’s environmentally friendly features.
Don't miss the TI-36 eco RS calculator introduced in the same year.

Texas Instruments introduced in April 2004 a slightly redesigned TI-30 ECO RS for the German market.
"The important thing about the Blue Angel is the bottom line result: a positive balance for the environment."
the tension between ecology and economy, the line of argument which leads to a
solution for all parties – business, consumers, commercial purchasers and not
least the environment – is both simple and compelling; ecologically optimised
products provide sustainable relief to the strain on the environment.
Environmental awareness in the behaviour of consumers is the decisive factor in
the provision of ecologically beneficial products and services by industry and
retailers. However, in order to evaluate the environmental properties of
products and services, consumers need reliable information and clear labelling.
This is where the Blue Angel comes in: it guarantees an ecologically better
alternative product according to defined criteria – and it enables consumers
to demonstrate for their "right to the environment" in the things they
The Blue Angel is not based on directives and prohibitions; it is based on information and motivation – and the conviction and commitment of producers and consumers alike.
So what are the results of the Blue Angel today? About 710 companies and 3,800 products use this environmental label. And about half of the consumers in West Germany and almost a third in East Germany take it into account when they go shopping. This makes the Blue Angel a signpost for the environmental awareness of consumers.
The Blue Angel rewards businesses which show commitment, creativity and innovation for the protection of the environment. It highlights products and services which are optimised in their impact on the environment. The Blue Angel offers companies added credibility to advertise their ecologically beneficial products in the market. And according to the users of the label, the Blue Angel has stimulated competition for ecological innovation and the ecological quality of the products and services offered. It is agreed that the classics of the Environmental Label – such as returnable bottles and recycled paper – have long become successfully established in the market. Any you will not find a DIY store which does not sell low-pollutant paints and varnishes bearing the Environmental Label. The Blue Angel was and still is the trendsetter for product-related environment protection.
These points alone are sufficient reason for me to appreciate the Blue Angel as a valuable and indispensable instrument in our environmental policies. It is a dynamic environmental label which takes an abstract principle and fills it with life and meaning.
I wish the Blue Angel every success as it continues along this path.

is quite interesting that not only the two calculators TI-30 eco RS and TI-36
eco RS decorated with the Blue Angel comply with the requirements of RAL-UZ 47
but even the twin TI-30Xa Solar.
above mentioned RAL-UZ 47 covers a lot of solar powered
products, please find below a version stripped down to cover only pocket
calculators. Reading these criterias carefully points it out that the Blue Angel
is just a marketing concept, not a development target. There are only four
cells with an efficiency to supply the calculator at 50 lux
battery, not even a holder for it

of such a calculator is its volatile memory.
