Solar Operations

Tonian provides an industry-leading, full scope O&M Service, so you can relax knowing your plant is being well-cared for. Our O&M division is entirely focused on managing all facets of solar O&M service. The team’s program for preventative maintenance and regular maintenance reports are agreed upon with clients before starting with each project. Our re-active maintenance response times are some of the fastest in the business. We offer a 24-hour emergency response line every day of the year and a site optimization service to ensure your site is running as efficiently as it can.
We possess industry leading expertise in design, operations, and maintenance for utility scale solar. Our services extend beyond traditional O&M to include critical spare parts sourcing, site restoration services, and reengineering of existing facilities to improve efficiency and reduce operating costs. We have the technical knowledge, experience and resources to deliver industry leading service to the solar industry. Our production and uptime guarantee means you can rely on sites to perform to their designed specification with performance above 99%.

With solar sitting on the horizon of unprecedented expansion, we work together with our members to create the right regulatory and business environment to take solar to the next level. We’re committed to offering a high-quality service at a fair price. Through a combination of hard work, technical know-how, professionalism and transparency, we seek to look beyond the immediate O&M requirements of solar parks to understand and mitigate the long-term issues that could impact their performance and value. We work to the very highest quality standards to ensure the best possible results and returns.

For each solar site under management, you will be provided with a direct line to an account manager, who will handle the day-to-day workings of your site and be the first point of contact for any issues. We don’t believe you should have to wait for information or updates.
