RESIDENTIAL SOLAR FREQUENTLY ASKED QUESTIONS

Answers To The Most Common Residential Solar Questions

How do I know if my home is suitable for solar?

If you have a roof with good sun exposure (ideally north-facing), minimal shading and use a fair amount of electricity during the day, solar is likely a great fit. We’ll assess your property to confirm suitability.

What is a solar battery and do I need one?

A solar battery stores the excess energy your panels generate during the day so you can use it at night or during power outages. It’s ideal if you want energy independence, more savings, or backup power.

How much does a residential solar and battery system cost?

Prices vary based on system size and brands chosen. As a guide, a 6.6kW system without battery starts around $4,000–$6,000 (after rebates), while adding a battery like Tesla Powerwall may bring the total to $12,000–$15,000. We’ll tailor a quote to your needs.

Can I add a battery to my existing solar system?

Yes! Most systems are battery-ready and we can retrofit a compatible battery to your current setup after assessing your inverter and panel configuration.

How long will my solar battery last?

Most batteries have a warranty of 10 years and a lifespan of 10–15 years. Brands like Tesla and Sonnen offer high-quality, long-lasting solutions with strong performance guarantees.
