The Company

Plug the Sun designs, develops, manufactures, and integrates the most innovative solar off-grid solutions to improve access to electricity all around the world. 

Plug the Sun is the next generation of portable solar power kits, solar home systems and mini-grids suitable for your room, house, workshop and community. Thanks to propriety technology, all Plug the Sun products feature high density power electronics and smart energy management systems to achieve the best reliability and performace for our customers' power needs. 

Plug the Sun systems can also be tailored according to your unique needs; they truly are the complete home and village solar power solution. We can offer 'turn-key' assistance, overseeing 360° of the project implementation from start to finish, integrating the most advanced technologies, providing quality installations and maximum technical reliability.

The Challenge

Solar Home System (SHS) is a stand-alone kit powered by one or more PV panels that, thanks to a battery storage application, can provide electricity in remote areas where the grid is not present. This Solar Home System is able to meet households and rural communities basic needs, supplying power for lighting and appliances.

Opportunities for Renewables

Solar Home Systems contribute to the improvement of the quality of life of rural communities by:

  • Reducing indoor air pollution and therefore improving health by replacing kerosene lamps

  • Providing new jobs and business opportunities

  • Providing lighting at night

  • Facilitating the access to information and communication (radio, TV, mobile phone charging).

Renewable Solution

In a Solar Home System we can find many components that are assembled and connected together.

The PV panels are mounted on a pole that is fixed on the ground through appropriate foundations. The tilt and the orientation of the PV modules must be chosen accurately to maximise the energy production during the day. The PV modules must be usually oriented south/south-east (in northern hemisphere), north/north-west (in southern hemisphere) with a tilt between 10 and 30° depending on the latitude. For Plug & PlaySolar Home Systems there is no need of foundations, because the PV panels can be placed and mounted easily in many places, facing the sun.

The power of the PV panels is calculated on the daily energy needs and the battery capacity.

The solar PV panels are connected through a solar cable to a component called “Charge Regulator”. The charge regulator has the function of checking and regulating the voltage and the incoming electrical current, keeping them at the correct value for the solar battery, to avoid its overcharging and overvoltage. It may also prevent completely draining (“deep discharging”) a battery, or perform controlled discharges, depending on the battery technology, to extend battery life.

Solar Power Batteries are the core of the Solar Home System and have the function of accumulating electricity that can also be used at night or in presence of clouds. They are made of Lithium (LiFePo4) or high performance silicate depending on the environment and the kind of application. Lithium batteries have an high energy density, fast recharge and reliable life expectations. Silicate batteries are cheaper, with a longer life-time compared to standard lead-acid and they can operate in a wide temperature regime.

Depending on their dimensions, Solar Home Systems can operate at a rated voltage of 12-24-48 V direct current (DC) or alternating current (AC), providing electricity for DC/AC appliances such as lights, fans, radios, small TVs and fridges. They can be useful not only for households, but also for businesses and utilities such as shops, schools and health centers.
