Solar Grid-tie systems, the energy produced by solar panels is directly connected to the electrical power grid by the inverter. The main advantage of this system is that there is no need for storage batteries.

Grid-tie solar is the most efficient use of solar panels. Systems that store energy in batteries lose a lot of energy through chemical reactions thus bringing down the efficiency of the system. 

Instead of storing the power in batteries (which also degrade over time), you’re helping power your institution in real time.

 A solar grid-tie system is ideal for institutions that have a very high daytime load (use most of their power during the day). Eg. Factories, Farms, Hospitals, Clinics, Serviced Apartments, Offices, Malls, Schools, Hotels & Lodges, Rental Properties.

For this system to make financial sense, you need to have an electricity bill of Ksh. 50,000/month and up. By adopting to a solar grid-tie system, you can regain your investment back in an average of 2 years after which you can start saving money you would be otherwise paying to the electrical power grid.

Are therefore most suitable for institutions that use most of their power during the day. By installing a Grid-tie system, you are able to make use of the sun's free energy as it is being generated.
