Residential Rooftop Solar

For homeowners tired of unpredictable utility bills and afternoon load-shedding, a rooftop solar system offers a way to generate a meaningful share of household electricity on-site. CZ Engineering designs residential systems around your actual consumption pattern — reviewing a year of DESCO, DPDC, or NESCO bills before recommending a system size, rather than defaulting to a one-size-fits-all package.

Where the local distribution utility supports it, we register systems under the BERC net metering guideline, allowing surplus daytime generation to offset consumption drawn from the grid at night. This requires a formal application, a bi-directional meter, and utility sign-off, all of which we manage on the household's behalf so the paperwork never falls on the homeowner.

Rooftop solar also acts as a hedge against future tariff increases and reduces reliance on diesel generators during extended outages, particularly when paired with a small battery buffer for essential circuits such as lighting, fans, and refrigeration.
