Reduce your energy costs by 50% with fully funded solar solutions

Solar photovoltaic (PV) technology captures sunlight and converts it into electricity using semiconducting materials. This process involves solar panels mounted on the roof of a building or in an open space, which generate direct current (DC) electricity. An inverter then converts this DC into alternating current (AC) electricity, which can be used to power your business operations or fed back into the grid.

Yes, solar PV systems can still generate electricity on cloudy days, though the efficiency is lower compared to sunny days. Modern solar panels are designed to maximise light absorption and can produce significant energy yields even under diffused sunlight.

Solar PV systems require minimal maintenance. Regular cleaning to remove dust, debris, and other materials that could obstruct sunlight is recommended. Periodic checks by a professional solar PV engineer should be carried out to ensure all components are functioning correctly and efficiently and to identify any repairs needed. JLM offers comprehensive maintenance packages covering all necessary inspections over the lifetime of your system.

Solar PV systems are designed to be durable and long-lasting — robust enough to withstand expected temperature cycles and weather effects over an extended period. Most systems come with a warranty of 20 to 25 years and will continue to operate effectively beyond this period. As with any equipment, the longevity of your system will vary based on the quality of components used and the level of maintenance performed — which is why JLM only installs the most trusted brands.
