Installing commercial solar panels and battery storage provides cost savings by generating your own electricity, reducing reliance on the grid.

It also offers energy independence and environmental sustainability by utilising clean, renewable energy sources.

To determine the right size of the solar panel system and battery storage for your commercial property, consider factors such as your energy usage patterns, available roof or ground space for solar panels, and desired level of backup power during outages.

Consulting with our team can help assess your specific needs and recommend an appropriate system size.

When choosing a commercial solar panel and battery storage provider, consider factors such as their experience, reputation, warranties offered, installation quality, customer service, and financing options available.

The costs associated with installing commercial solar panels and battery storage include upfront installation costs, ongoing maintenance expenses, and potential financing costs.

Yes, there are often incentives, rebates, and financing options available for commercial solar and battery storage installations, including various financing programs such as leases, loans, and power purchase agreements (PPAs).

The time to install a commercial solar panel and battery storage system can vary depending on factors like system size, complexity, and local permitting requirements, but a smaller system typically takes less than a week whilst bigger systems take closer to a few weeks/months from start to finish.

The expected lifespan of commercial solar panels is typically around 25 to 30 years, while battery storage systems can last anywhere from 10 to 20 years, depending on factors such as usage patterns and maintenance.

Yes, you can still use electricity from the grid with a commercial solar and battery storage system, particularly during times when your energy demand exceeds what your solar panels and batteries can provide, such as during peak periods or when there is limited sunlight.

Battery storage works in conjunction with commercial solar panels by storing excess electricity generated during the day when the sun is shining. This stored energy can then be used later when solar production is low, such as at night or during periods of high energy demand.

During grid outages, a commercial solar and battery storage system can provide backup power to critical loads, such as emergency lighting, refrigeration, or essential equipment, depending on the capacity of the battery storage system and the configuration of the backup system.

Installing commercial solar panels and battery storage can potentially reduce your utility bills by generating your own electricity and storing excess energy for later use, thereby decreasing your reliance on grid electricity.

Yes, there are maintenance requirements for commercial solar panels and battery storage systems, including periodic inspections, cleaning of solar panels, and monitoring battery performance.

Installing commercial solar panels and battery storage contributes to environmental sustainability by reducing reliance on fossil fuels, decreasing greenhouse gas emissions, and utilising clean, renewable energy sources.

Yes, our commercial solar panel and battery storage systems come with the option of monitoring capabilities that allow you to track the performance and energy production of your system remotely.

Our warranties and guarantees for commercial solar panels and battery storage installations typically cover equipment performance, workmanship, and product defects.
