Heat and cool your home for a fraction of the cost

Why Sun System?

Traditional systems burn energy to create heat or cold. A heat pump moves it instead, using a fraction of the energy for the same comfort. Combined with solar, it can run almost entirely on your own energy.

What you pay

Heating and cooling account for between 40% and 60% of the bill in most homes. On the coast that figure climbs higher still in summer, with air conditioning running non-stop for months.

Rooftop solar panels generating clean, sustainable electricity

When you use it

Heating and cooling work hardest right at peak hours: hot evenings and cold mornings. That is when every kilowatt hour costs most and the equipment works hardest.

What you control

With a conventional system you control the thermostat. Nothing else. Not the efficiency, not the price you pay, not how much energy the equipment wastes.

Heating and cooling need not be your biggest expense

Heating and cooling are the biggest energy cost in almost any home. A heat pump cuts that cost dramatically because it moves heat rather than generating it, and combined with solar and a battery the saving multiplies in every season.

All your comfort, from the grid

Every degree of comfort comes straight from the grid.

One mode: flat out

Efficiency lost

No anticipation

They cannot pre-heat or pre-cool automatically during sunny hours.
