Battery questions
Most homes suit roughly 10–16 kWh. We size it from your evening usage and backup needs.
If it’s set up for backup, yes. Installers can back up the whole home or just essential circuits like the fridge, lights and internet.
Our partners supply leading brands including Tesla, Sigenergy, GoodWe, Sungrow, Enphase and FoxESS.
The federal Cheaper Home Batteries Program takes around 30% off the upfront cost of an eligible battery, applied by your installer. The rate steps down on 1 January 2027.
A vetted, accredited solar company. Once we’ve worked out your plan, we arrange a proposal from a solar company or installer and give you their details. Your contract, installation and warranties are with that company. They pay Yellowstone Solar a referral commission if you sign, and agree to charge you the same price as going to them directly.
