What is a regulator?
A regulator converts power created by your solar panels into a suitable power source for your battery to draw from. The regulator will stop charging the battery once it is fully charged. It will then start charging the battery again once the power drops below preset voltages.


How much noise does a solar panel system make?
Solar panel systems are SILENT and are able to be used in all National Parks. Certain brand of inverters are louder than others, it depends on if there is a built in fan or not - Fronius for example are louder than SMA inverters. 


Who can I get to install solar panels on my caravan?
An auto electrician should be able to carry out the installation of your panels.


Can I order wholesale?
We do have certain products available for wholesale. Please contact one of our friendly sales team by e-mailing for more information.


What is an STC? 
Small Scale Technology Certificates (STCs) are created when any renewable energy system is installed i.e. pv solar power, heat pump or solar hot water systems. The number of STCs created depends on the size of the system and the location. Once installation is complete then you are eligible to claim these STCs as a discount (Please Note: PV system must be installed by an accredited installer, solar hot water and heat pumps must be installed by a licenced plumber). The Energy Hub are registered STC traders and will purchase your STCs at the given market price upon completion of installation provided that all documentation is submitted within 12 months of installation - Processing time may vary and is subject to approval. Value of the STCs is subject to fluctuation.

How is water heated using the Stiebel Eltron heat pump? 
A Heat Pump works like a refrigerator, only in reverse. Air which contains solar heat energy is extracted by the Heat Pump to heat water. A fan draws air through an evaporator which contains very cold liquid refrigerant. The heat in this air is absorbed by the refrigerant, turning it into a very hot liquid. The hot liquid refrigerant is then compressed to a "super heated" gas via a compressor. The gas is then circulated to a condenser, where the heat from the gas is transferred to the water in the tank. The now cool refrigerant is then reused and the cycle starts all over again. Power is only required to operate the compressor to move the heat around the system, not to heat the water.

When will I receive my order?
Please allow 5-10 business days for delivery. If there is a delay one of our customer service team will make contact with you.
