The top KPIs are critical in the Solar PV industry as they provide measurable values to gauge the performance of various aspects of solar operations, including installation efficiency, energy production, financial returns, and system reliability. These indicators allow companies to optimize the energy output of their installations by tracking the actual performance against expected energy generation, thus ensuring the solar assets are producing energy at peak efficiency.
KPIs also help in monitoring the degradation of solar panels over time, which is vital for maintaining long-term profitability and sustainability.
This article showcases the Most Critical 12 KPIs for Solar PV and Associated Benchmarks.
Return on Investment (ROI) is a crucial KPI that measures the profitability of investments relative to their costs.
It directly influences financial health, operational efficiency, and strategic alignment within an organization. A higher ROI indicates effective resource allocation and strong performance indicators, while a lower ROI may signal inefficiencies or misaligned objectives.
Executives rely on this metric to drive data-driven decisions and improve overall business outcomes. Learn more about the Return on Investment (ROI) KPI.

These 12 Solar PV KPIs were selected to provide a balanced view of financial returns, operational reliability, and customer dynamics. They span leading indicators like System Uptime and Supply Chain Resilience, lagging financial metrics such as ROI and IRR, and customer-focused measures including CAC and Customer Retention Rate. This subset captures the full value chain from acquisition through asset performance to end-of-life sustainability.
Track Customer Acquisition Cost (CAC) alongside Customer Retention Rate to assess customer lifecycle efficiency—rising CAC with flat retention signals acquisition inefficiency. Monitor Mean Time Between Failures (MTBF) in relation to Mean Time To Repair (MTTR); a declining MTBF with stable MTTR indicates increasing failure frequency rather than repair delays. Compare System Uptime with Supply Chain Resilience—divergence suggests operational disruptions rooted in supply constraints rather than maintenance issues.
Prioritize ROI and CAC first, as they are foundational financial KPIs with readily available data and immediate impact on investment decisions. Follow with System Uptime to diagnose operational health and its effect on revenue continuity. These three provide a diagnostic core before expanding to customer satisfaction and recycling metrics. The full Solar PV KPI set, with formulas and benchmarks, is accessible in the KPI Depot database.

What does unlimited web access mean?
Our complete KPI and benchmark database is viewable online. Unlimited web access means you can browse as much of our online KPI and benchmark database as you'd like, with no limitations or restrictions (e.g. certain number of views per month). You are only restricted on the quantity of CSV downloads (see questions below).
What's the difference between the Basic and Pro plans?
Both plans include unlimited web access to the full KPI database and benchmark database, interactive Strategy Maps for every KPI group, and 2,000+ OKR examples.
The Basic plan includes 5 CSV downloads per month and is designed for individual research use.
The Pro plan includes 20 CSV downloads per month and unlocks the full deliverable workflow: save your customized Strategy Maps and export them as Balanced Scorecard CSV templates, complete with KPI names, formulas, monthly tracking columns, and links to benchmark data. Open the export in Excel and start tracking immediately.
Can I try the interactive Strategy Map before subscribing?
Yes. Every KPI group includes an interactive Strategy Map that anyone can open, no subscription required. You can add, remove, and rearrange KPIs across the 4 Balanced Scorecard perspectives (Financial, Customer, Internal Process, and Learning & Growth) to build a map tailored to your organization.
Saving your customized map and exporting it as a Balanced Scorecard CSV template are Pro plan features. To help you turn that CSV into a polished, ready-to-track scorecard, we also offer 5 free Balanced Scorecard Excel templates that pair with your export.
Can I download KPI group data as a CSV?
Yes. You can download a complete KPI group (which includes all inclusive KPIs and respective attribute data) as a CSV file. To gain a better sense of the KPI data included, you can download a sample CSV file here.
Can I download benchmark data as a CSV?
Yes. On individual KPI pages, you can download all available benchmarks for that KPI as a CSV file. To gain a better sense of the benchmark data included, you can download a sample CSV file here.
Each CSV download, whether for a KPI group or for benchmarks, consumes 1 of your monthly CSV download credits.
What if I need more CSV downloads in a month?
You can purchase additional download credits at any time: $8 each on the Basic plan, $5 each on the Pro plan. Credits never interrupt your workflow, so you'll never be locked out of a download you need mid-project.
How does KPI Depot pricing compare to other benchmark data sources?
Benchmark data is traditionally expensive. Subscription research and advisory services typically run $2,400 to $70,000+ per year, and a single benchmarking assessment can cost $5,000 at nonmember rates. Compiling benchmarks yourself from public sources takes weeks of analyst time per project.
KPI Depot includes unlimited web access to all 35,645 source-attributed benchmarks on every plan, starting at $499 per year. Each benchmark documents its source, company size, time period, industry, geography, and sample size, so your targets hold up under scrutiny.
Can I cancel at any time?
Yes. You can cancel your subscription at any time. After cancellation, your KPI Depot subscription will remain active until the end of the current billing period.
Do you offer a free trial?

The remaining KPIs in the group are tabulated on the page as well. This gives you a clear sense of the depth and quality of our KPI data.
You can also open the interactive Strategy Map for any KPI group and customize it yourself: add, remove, and rearrange KPIs across the 4 Balanced Scorecard perspectives. This is the same mapping tool subscribers use, so you can experience the full workflow before deciding (saving and exporting your map requires a Pro subscription).
You can also preview benchmark data on individual KPI pages, where you'll see how benchmarks are structured, including dimensions like geography, company size, industry, and time period.
To see what a subscriber download looks like, you can download a sample KPI group CSV file and a sample benchmark CSV file (see questions above).
Once you subscribe, you unlock full access to the entire KPI database and benchmark database with no viewing limits. We encourage you to explore the platform and see the breadth of coverage firsthand.
