Hayleys Solar introduces ‘PV-DG’ solution


Hayleys Solar, the specialised renewable energy solutions arm of Fentons Ltd., recently introduced a state-of-the-art ‘PV–DG’ solution to the local business sector to help effectively utilise solar energy and minimise fuel costs. The fuel-saving system is specifically meant for businesses that have invested in solar rooftops but continue to face the challenges of increased diesel requirements for generators, amidst today’s drastic shortage and the price hikes.

It is designed to synchronise the solar PV systems with Diesel Generators with the help of a priority controller which can save up to 70% fuel costs depending on the loading of the generator. As the cost incurred for fuel continues to rise, it is estimated that this ‘PV-DG’ system will save businesses over LKR 152 per kWh as per the latest fuel prices and will help to significantly reduce and optimise fuel usage at a national level.

A key drawback of on-grid solar solutions is that the solar power system automatically switches off during a power cut, wasting the solar energy that could be generated during that period. Ensuring maximum utilisation of the power generated by the solar system during the power cuts without the use of a battery, the ‘PV-DG’ solution is perfectly designed to assist businesses to combat these energy and fuel-related challenges. The ‘PV-DG’ solution can be conveniently extended across most commercially available inverter brands.

Backed by a thorough data monitoring via the cloud which enables remote monitoring to control the system, this ‘PV-DG’ solution controls the inverter output of the solar PV system. Engineered according to the latest German technology, the controllers are manufactured by a company which has successfully completed numerous high-end projects worldwide. The controller also features protection against reverse power which is crucial for the synchronisation of a system of this nature.
