Glass-Glass PV Module
IN THE PAST and currently, the standard photovoltaic module has been manufactured using 3.2 -4mm glass on the front and a polymer-based insulating back sheet.
Despite well known disadvantages of such concept many years has been no real changes to improve technology of manufacturing PV modules.
PV industrial machinery and glass processing technologies limited ability to step-out of using polymer-based
backsheet in large scale of PV module production. Significant step further of glass tempering technology made possible to substitute polimer-based back sheet for ultra thin- 2 mm glass.
ViaSolis is a pioneer of using Glass-Glass PV module manufacturing technology.
This module provides important advantages incorporate use of thin glass that increases light transmission. This corresponds to 4% increase in yield (kWh per kWp) or in other words to a reduction of all optical losses in a solar module by 40%.
ViaSolis PV cell surface is specifically designed for the structure of lamination
foil, which reduces banding losses up to 60 % (0.8% versus standard module - up to 5%)
Innovative approach as a optimal weight of the PV module provides extensive product’s integration in to construction and architectural solutions.
Via Solis photovoltaic modules can be manufactured according to the needs of individual clients by exploiting the possibilities of the colour spectrum, size, desirable shape, different light transmission or insulating characteristics.

BOSS - Business Opportunities with Solar Systems
OFF-GRID solar power systems can be an important factor to support rural development in areas that are not connected to the electricity grid.
Most projects and concepts for rural electrification target the basic infrastructure needs such as the electrification of hospitals schools local administrations and private households.
But the commercial sector is another very important area of activity since prospering commercial activities are essential for the economic development of rural communities and therefore also contribute to social development.
Common names for energy solutions for the commercial sector are productive use of energy or Business Opportunities
with Solar Systems (BOSS. As a system integrator the company Phaesun in cooperation with local partners and component manufacturer is developing and implementing different complete solar kits that can be used for income generation in rural non-electrified areas.
These solar powered systems for commercial use range from solar powered systems for daily services such as hair cutting TV and cinema mobile phone charging cooling and freezing of food and drinks to food processing such as juice squeezing and grain milling.
Services in rural areas in developing countries are often poorly developed due to the lack of electricity access. The processing trade is often concentrated on urban areas.
Off-Grid solar power systems offer a unique opportunity to implement new services in non-electrified rural areas and ensure that further process units will remain in the hands of locals.

SolarAid SunnyMoney
INTERNATIONAL DEVELOPMENT charity SolarAid established SunnyMoney a visionary social enterprise to revolutionise solar light ownership in Africa by catalysing a market for solar amongst off- grid communities. SolarAid identified the market barriers werent just lack of quality products but one of trust distribution and scale. Solar power was not accessible to the majority markets in Africa those with low incomes living far from the grid.
This has been a great success with over a million solar lights distributed by March 2014 60% of which were sold in that financial year. SunnyMoney has achieved this by developing a community distribution model to raise awareness of solar products in partnership with Ministries of Education in Kenya Zambia Malawi Tanzania and Senegal. As trusted figures in the community, teachers play a crucial role in encouraging
