Answers to common solar energy questions

Most households cut their electricity bills by 40–70% from the first year. Your exact savings depend on roof size, sunlight hours and local tariffs — our free assessment calculates your payback period before you commit.

A typical home installation takes 2–4 days on the roof, plus permits and grid connection. From signed proposal to switch-on, most projects finish within 3–6 weeks.

Yes. Panels still generate 25–40% of their rated output under cloud cover, and battery storage carries you through evenings and overcast stretches.

Very little — a rinse once or twice a year and an annual health check. Every Sunvault system includes real-time monitoring that alerts us if output ever dips.

Panels carry a 25-year performance warranty, batteries 10 years, and our workmanship 5 years. If a warranted part underperforms, we handle the manufacturer claim for you.

Yes — our Essential, Advanced and Premium plans are fixed-price starting points you can reserve right here. Every order begins with a free on-site assessment, and we confirm the final design with you before installation day.
