Is the solar array in this project 10kWp?

No. The project uses a 10kW-class system or inverter and twelve 600W solar modules. The modules add up to a 7.2kWp array. Compare the inverter power and solar-array capacity as separate figures.

How much energy can two 51.2V 300Ah batteries store?

Voltage multiplied by amp-hours gives about 15.36kWh of nominal energy per battery, or approximately 30.72kWh for two. A system design must then account for depth of discharge, state-of-charge limits, conversion efficiency and the selected critical loads.

Is this flat-roof mounting hurricane-proof?

The project record describes reinforced aluminium mounting for a hurricane-prone environment. A new home's final design must still be checked against its roof structure, anchoring, roof-edge wind pressure, fasteners and project-specific design wind speed. Hurricane-proof should not replace documented engineering.

Can every Montserrat home be installed in two days?

No. This project's installation and commissioning took two days. The schedule for another home will depend on its roof, cable routes, electrical modifications, weather and level of site preparation.

What should I send Sunchees for a quotation?

Send the exact location, twelve months of electricity use, a list of critical loads, photos of the roof and equipment area, shading and distribution-board information, your backup objective, and details of wind and salt exposure. We can then assess the array, inverter, battery and site requirements separately.

Flat Roof Home Solar in St Peter Montserrat

Nearby houses and a hillside are visible from the roof of this St Peter home. Solar panels stand in separate groups on the concrete roof, while two batteries and inverter equipment occupy an indoor space with green walls.

The two storey house has four bedrooms and two bathrooms. We completed solar installation and electrical commissioning in two days, providing generation and storage for refrigeration, lighting and television.

Separate tilted panel groups on a concrete flat roof overlooking hillside homes in St Peter, with two indoor battery cabinets.

Using a flat roof to collect sunlight

The mounting raises one side of each panel group, creating a tilt on the flat roof. Space remains between the groups. Unlike panels following a pitched roof, this arrangement needs the mounting to establish the angle and the layout to account for shadows between rows. The surrounding hillside may also matter to early or late sunlight, depending on its direction relative to the array.

Twelve 600W panels form a 7.2kWp array, paired with 10kW class single phase equipment and two 51.2V 300Ah lithium batteries. Together, they provide approximately 30.72kWh of nominal storage. The rooftop layout affects how panels receive light, while the refrigerator, lights and television determine how electricity is used indoors.

Storage keeps some daytime generation available for the evening and for appliances connected to the backup circuits during an outage.

Sun and wind both matter on an island roof

The project information describes reinforced aluminium mounting for the hurricane environment. On Montserrat, the way panels attach to a concrete roof is an important part of an installation. Mounting, connections and the roof structure work together; the material name alone cannot establish a wind rating.

This retrofit connects a hillside home's existing flat roof with indoor storage and everyday appliances. The roof provides a place to generate electricity, and the batteries provide a place to keep some of it for the household's later needs.
