Grid Connected

Grid connected photovoltaic (PV) power systems offer the simplest renewable power system option for on-site generation (also known as embedded generation) at the least capital expense. They are also generally maintenance free and can be considered an 'install and forget' investment. 

How it works:


Many rules and regulations dictate the system size that may be installed on a particular section of the grid, its eligibility for a feed-in tariff and if a system can export power to the grid.


Is a Grid Connect PV Solar System the right solution for your business?

A commercial or industrial PV solar system is unlikely to qualify for a feed-in tariff (i.e. you may not be able to sell excess generated power to the grid). This means it is important to match system generation with site consumption. Failure to do so risks having a system that generates power that you can neither use or sell, reducing your return on investment. 

The diagram below shows how a PV system can match the energy consumption of a commercial site. 



Grid connect PV systems are most suitable for sites that have high daytime energy use. However, if your business has high night time consumption as well, or does not operate seven days a week, a PV system may still be a viable option. Tropical Energy Solutions includes all solar yield and site consumption calculations as part of our system design process, reducing the risk of poor financial returns. 

It is also important to consider the electricity tariff you are using. Some tariffs, particularly those that are demand based, have small consumption charges. This affects the financial performance of a PV system. On the positive side, the reduced requirement for grid supplied electricity may also qualify you to change to a more efficient tariff. Our PV system financial performance calculations use the current tariff prices used by the customer, providing accurate electricity cost reductions and return on investment data.

The step up from a grid connect power system is a hybrid power system, which uses batteries to supply additional power. A hybrid power system uses the grid as a backup for when additional power is required or to help charge the batteries during extended cloudy periods. This means you can enjoy lower electricity bills while maintaining absolute energy security. It also allows the installation of a smaller system, with reduced capital costs, as you do not have to replace all of your power needs with renewable energy.
