Why Install Solar PV

How solar panels benefit your business

Generate Free Electricity

Solar photovoltaic panels generate electricity when exposed to light, allowing direct use of this free energy.

Save on Energy Bills

Sunlight is free, so once you've paid for the solar panels installation, you can save up a lot on your electric bills.

Cut Your Carbon Emissions

By installing solar panels, you are doing your part to lower your carbon footprint & help protect our endangered planet.

Store Energy for Later Use

Excess electricity generated by solar panels can be stored and later used if demand exceeds production.

Return on Investment

Typical solar panel systems provide free electricity for over 25 years, offering an attractive return and quick payback.

Enjoy Free Hot Water

Solar PV systems can be configured to use free solar energy to heat your water rather than exporting it back to the grid.

25 Year Guarantee

TRE Energy use only Tier 1 products known for their quality & long-lasting reliability, performance & efficiency.

Profit from Excess Energy

If your system is producing more solar power than you need, sell the excess energy to the grid via an Export Tariff.

Enables Energy Independence

Self-generation from solar reduces reliance on grid energy & protection from energy shortages and price hikes.
