Solar Panel Installation in Fanling

It exports to the grid under your market's scheme — net metering, feed-in tariff, or export payments. Export rates are usually well below retail import rates, which is why maximising self-consumption (timers, smart appliances, EV charging) beats chasing export credits.

By system size in kilowatts (kW), quoted as an installed price including panels, inverter, mounting, electrical work and grid paperwork. Batteries are a separate large line item. Compare quotes on price-per-kW with equivalent component tiers, not just the headline total.

Size to your daytime consumption and roof space: pull a year of electricity bills, and let the installer model self-consumption vs export. Typical homes land between 4kW and 10kW. Oversizing slightly is usually cheap at install time and future-proofs for an EV or heat pump.

Panels carry 25-30 year performance warranties (typically 85%+ output at year 25). Inverters are the consumable — expect one replacement around years 10-15. Quality mounting and cabling should match panel life; that's where cheap installs cut corners invisibly.

Anywhere from 3 to 12 years depending on your electricity price, sunshine, self-consumption share, and incentives. High daytime usage (working from home, pool pumps, EV charging) shortens payback dramatically because self-used solar displaces full retail-rate electricity.

Not to benefit — grid-tied solar without a battery is the fastest-payback configuration in most markets. Batteries add backup power and evening self-consumption but often double system cost. Decide battery separately on outage frequency and your tariff structure.

Get 3+ quotes for Fanling homes with identical framing: same system size, named panel and inverter models with warranty terms, mounting spec for your roof type, and grid-connection paperwork included. The cheapest quote usually differs on inverter tier and workmanship warranty — the two things that fail first.

Mostly village-house owners in the New Territories and owners of low-rise buildings with roof rights — high-rise flat owners can't. The FiT premium rate is the economic engine: systems commonly pay back in 8-10 years on FiT income.
