Off-grid photovoltaic system

How it works

Panels supply equipment and charge batteries through regulation equipment. Stored energy supports selected appliances without solar production. Autonomy depends on usable battery capacity, sunlight and consumption.

Equipment and needs

Size panels for daily and seasonal demand. Use a compatible solar controller or inverter-charger, batteries sized for autonomy and priority loads, and an inverter suitable for running and starting currents. Include cables, protection, earthing and mounting. Provide appliance powers and operating hours, plus a suitable protected battery and inverter location.

Sizing and follow-up

We assess lighting, refrigeration, pumps and other loads separately, then define storage reserve and usage priorities. Auxiliary supply can be studied for unfavourable periods. Monitor charge and respect operating limits. Batteries, connections and conversion equipment require manual-compliant servicing; cleaning follows site conditions.

Is autonomy unlimited?

No. It is designed for defined demand and reserve. Higher consumption or several cloudy days can exhaust storage.

Can I run powerful appliances?

Yes, if the system is designed for their running and starting power. Provide pump, air-conditioning and motor specifications.

Can the system be expanded?

Expansion depends on compatibility of batteries, inverter and existing mounting, and should be studied for your future needs.

Price and warranties

The price depends on equipment, access and connections. Exact references, quantities, accessories and services are confirmed after the site study. Panel, inverter and battery warranties follow their manufacturers; durations and conditions are stated in the proposal.
