The most critical assets in the oil and gas industry often sit exactly where the electricity grid does not.

Wellheads, pipeline valve stations, cathodic protection points and remote telemetry units are scattered across deserts, coastlines and offshore approaches, far from any power line. For decades the default answer was a diesel generator. Today, off grid solar systems do the same job with none of the fuel, noise or downtime.

This guide explains how solar power supplies remote oil and gas infrastructure, where it delivers the most value, what goes inside a well designed array, and how to size one for continuous, unattended operation. It is written for the same engineers who already trust KLEEV for pressure, temperature, level and flow measurement, and for the certified enclosures that protect it.

01What are off grid solar systems?

An off grid solar system is a self contained power plant that generates and stores its own electricity, with no connection to any utility network. Sunlight is converted to direct current by photovoltaic modules, a charge controller manages that energy, and a battery bank stores it so the load keeps running through the night and through cloudy spells. The result is a quiet, fuel free power source that can run for years with very little attention.

That independence is the whole point. Where a grid connected installation borrows power from the network and a diesel set burns fuel that has to be delivered, an off grid array makes and keeps its own energy on site. For a remote oil and gas asset that may be hours from the nearest road, that difference decides whether a critical safety function stays powered or goes dark. There is no fuel gauge to watch, no delivery schedule to manage and no engine to service, only sunlight, a battery and a controller quietly doing their work.

02Why oil and gas is going off grid solar

Powering a remote site comes down to three broad choices. Extending the grid is slow and enormously expensive over long distances. Diesel generators are quick to deploy but bring a lifetime of fuel logistics, maintenance and emissions. Solar sits between them: a higher upfront design that then runs for years at almost no running cost.

The comparison sharpens once the full life of the asset is counted. A diesel generator looks cheap on day one, but fuel, filters, servicing, spares and the trips to reach a remote location add up every year it runs, and any missed delivery is a lost load. A solar package carries most of its cost at the start and then asks for very little, so across a ten or fifteen year life the total cost of ownership usually favours solar by a wide margin.

For the Gulf region the case is especially strong. Abundant year round sunshine means a modest array can carry a continuous load, and removing fuel deliveries to scattered sites cuts both cost and risk. Once commissioned, the array simply keeps working, which is exactly what an unattended safety asset needs.

03Where off grid solar delivers most: applications

The value of solar shows up wherever a small but critical load must run continuously in a place the grid forgot. Tap through the main oil and gas applications below.

04Inside an off grid solar system

A dependable system is more than a panel and a battery. Five parts work together to turn sunlight into power a critical load can rely on. Tap each block to see what it does.

05Sizing for reliability, not just sunshine

The difference between a system that runs for a decade and one that fails in its first cloudy week is design. Good sizing starts from the load and works backward: how much energy the equipment uses each day, how many days of autonomy it needs when the sun is weak, and how much array is required to refill the battery in between. Get these right and the system becomes genuinely unattended infrastructure.

Autonomy is the figure that separates a hobby installation from industrial infrastructure. A critical cathodic protection or shutdown circuit may need five days or more of storage so it rides through a dust storm or a run of overcast mornings without ever dropping the load. Heat matters too, because a battery in a hot enclosure ages faster and delivers less, so the Gulf climate has to be designed in from the outset rather than discovered later.

Use the indicative estimator below to see how load, run time and autonomy shape the array and battery. It is a starting point for conversation, not a construction drawing.

06Built for heat, dust and hazardous zones

A remote solar system in the Gulf faces punishing conditions: extreme heat, blowing sand, salt air near the coast and, on an oil and gas site, an explosive atmosphere. Hardware that would last for years in a mild climate can degrade quickly here, so every part is chosen for the environment it must survive.

In practice that means modules with robust framing and glass that shrugs off sand abrasion, batteries selected and housed to cope with high ambient temperature, mounting structures in hot dip galvanised or stainless steel, and cabling rated for constant ultraviolet exposure. Small choices like these decide whether the array is still performing to specification in year ten.

This is where KLEEV's two specialisms meet. The same certified housings from the KLEEV enclosure range protect the charge controllers, batteries and terminals of an off grid solar system inside a classified zone. You can read more in our guide to Ex proof enclosures, which explains the zone and marking system that governs any electrical equipment near flammable gas or dust.

07Standards and quality

Reliable solar power systems are built on recognised standards. Photovoltaic modules are qualified to IEC 61215 for design and IEC 61730 for safety, power electronics follow IEC 62109, and any electrical equipment in a classified area is certified to the IEC 60079 series for explosive atmospheres. Where the load is cathodic protection, the wider corrosion control practice follows guidance from bodies such as AMPP.

Beyond the paperwork, quality shows in the details: correctly rated cable for the desert sun, batteries suited to high ambient temperature, structures that will not corrode, and a design margin that keeps the load alive through the worst week of weather, not just an average one. Resources from research bodies like the NREL underline how much long term performance depends on this engineering discipline.

08Frequently asked questions

09The bottom line

Remote oil and gas assets cannot afford to lose power, and they cannot always wait for a fuel truck. Off grid solar systems answer both problems at once: independent, fuel free power that keeps cathodic protection, telemetry, safety instruments and lighting running through every night and every cloudy spell. The upfront design effort is repaid many times over in years of silent, low maintenance operation.

KLEEV designs and builds off grid solar systems for oil and gas across the region, pairing decades of instrumentation and enclosure expertise with solar engineering built for the toughest sites in the Gulf.
