Summer’s Coming — Is Your Site Ready to Perform?

For the Northern Hemisphere summer is just around the corner, and with it comes longer days, more sunlight, and higher expectations for solar output. It’s the season when your site should be working at peak performance, but there’s one problem that could be holding you back: soiling.

Dust, pollen, and debris build up fast during the dry season, and when your panels are coated, more sunlight doesn’t automatically mean more energy.

More Sun, More Power? Not Always.

It’s tempting to assume that summer guarantees a spike in production. But soiled solar panels are significantly less efficient. Soiling quietly reduces performance, sometimes by double-digit percentages, and it often goes unnoticed until your energy yield and revenue take a hit.

How Are You Scheduling Cleanings Right Now?

The real challenge isn’t cleaning panels but it’s knowing when to clean them. Many sites rely on:

• Pre-set maintenance cycles

• Visual inspections

• Decrease in energy yield

But guesswork, lagging indicators, or rigid schedules can cost you. Clean too soon, and you're wasting water, time, and labor costs. Clean too late, and you're losing energy and revenue.

Summer Is the Time to Optimize

This is where the ARES Soiling Station comes in. As solar output ramps up, your site deserves smarter tools—not just to measure soiling loss, but to help predict the most financially optimal cleaning times. Through our portal, you can access real-time data to support informed, data-driven decisions about the optimal timing and frequency of cleaning each year. For large-scale operators, the results speak for themselves:

• Up to 20% boost in annual energy production

• Net-zero cleaning costs through financially optimal scheduling

• Better ROI, and less manual guesswork
