Rapit heating of water

3 billion people cook food with biofuels, which contributes to both local and global environmental problems with deforestation and greenhouse gas emissions. GEC and the ecoInside project is funding the innovation project “Rapit heating of water”. With the invention, cooking is possible indoors and after sunset. Furthermore, saving time is not necessary because you do not have to search for fuel, and instead can spend this time on education or a paid job.

Joto Solutions is building a minature model:

  • Extremely fast heating of water. This along with a cooking unit optimized the taste of the coffee
  • Energy storage that can be charged with solar energy and/or electricity 
  • It can be made in dimensions so it becomes relatively mobile.
  • Works as a demonstrator of the technique, but also attracts attention to Löfbergs Lila.

Solar Tent

Solar Tent is an innovation where the tent fabric has built-in solar modules. 

Three different types of solar modules are tested on the prototype:

  • Organic solar cells
  • Crystalline solar cells
  • CIGS solar cells

Offgrid system

There are five different offgrid-systems of different sizes at Glava Energy Center. Offgrid-systems are stand-alone system of solar modules built on flexible solar frames and ground anchoring bolts, connected to the batteries. The purpose of the systems are to develop a cost-effective package for export.


The Offgrid systems in Glava are from SweModule and Innotech Solar. The frames are flexible and constructed of different materials. The idea is that you should be able to build them with the material you have at your disposal where they should stand. The modules are connected to independent batteries recovered from MacBat regularly serviced with MacBat technology.

The Offgrid system at GEC provides for the local outdoor lighting. It consists of LED lighting from SC Burman in a local direct current. The design of the system has been done in cooperation with the Nordic Solar system and integrated with a specially developed measurement systems from Metrum.


An export product

In 2012 and until mid 2013, the goal of the offgrid systems was to develop an export product of independent solar panels connected to a battery system for cost-effective short-term energy storage. Development work is ongoing in cooperation with, among others Ferroamp.

Ongrid system

Solar module park is a so-called ongrid system, ie a non-independent, network-connected system (209.8 kW). In the solar module park, GEC are testing different concepts of modules, frames, foundations and inverters.

There are two solar module parks; Solar module park 1 och Solar module park 2.

Solar module park 1

There are four existing sections of a total of 136.2 kW, of which 108.2 kW was built in 2009 and then was supplemented in 2012 with an additional 28 kW.
