Types of installations provided

On Grid or Grid Tied

An On Grid system allows you to save money using solar panels in addition to regular connected mains electricity.
Batteries and other stand alone equipments are not required, generally making this type of system the cheapest and easiest to install. Excess generated Electricity can be fed (stored) back into the grid enabling a reduction in your supply costs, lower bills !

Off Grid

An Off Grid system is a complete stand alone solution that requires no external Electricity supply, ideal for remote locations or for people wanting independence from local supply. The cost of this system and installation is generally higher than the other systems because of the need for a Battery Bank and other extra equipments. Depending on the quality of installed batteries, replacement time is 3 to 10 years.

Hybrid System

This system combines the best of the two other types of systems, priced between the two, but a little more expensive than ‘On Grid’ due to the additional installation and Batteries (or Generator) needed. Excess generated Electricity can be stored in the batteries and used in the evenings or when there interruptions to local grid supply.
