Energy Guard
Plant O&M Services
We're invested in your energy. Not just your uptime.
With Energy Guard™ O&M+Cleaning Services, you only pay 100% if your plant produces 100%. Whereas typical O&M contracts only put the provider on the hook for uptime, we’re on the hook for every cause of underperformance short of force majeure. If your plant underperforms, your fees are discounted at a percentage proportionate to its percentage of underperformance. This ensures that our incentives are aligned and that we’re invested in your energy — not just your uptime.
With Energy Guard, Erthos offers the most robust O&M coverage on the market.

ErthBot PV Array Cleaner
The ErthBot PV array cleaner is a dry nylon brush autonomous cleaning robot. Each ErthBot is designed to clean over 3.5 MWdc of PV array, making it the most cost-effective method for cleaning large-scale PV arrays in the industry. Custom-designed for use on an Earth Mount Solar PV array, the ErthBot cleaner is deployed nightly and returns to its charging dock after each use, ready to be deployed again the following evening. Erthos handles the operations and maintenance of the ErthBots, either wrapped into its Energy Guard O&M+Cleaning Service or as a stand-alone Cleaning-as-a-Service product.
