Commercial rooftop - shade mitigation
Issue: Intermittent tree shade reduced string output. Solution: module-level optimizers and string reconfiguration. Outcome: 12 percent annual yield uplift versus baseline.
Selected projects that increased energy yield and value
Shadystonewalk documents measurable improvements across residential, commercial, and utility installations. Our portfolio highlights how focused interventions recover lost energy and improve system predictability. Several projects began with modest upgrades such as inverter MPPT tuning and string rebalancing that produced immediate uplift. Other projects required module-level electronics to address persistent partial shading and mismatch. We provide pre- and post-implementation baselines and measurement plans so owners can see realized yields. Our portfolio demonstrates an emphasis on technical clarity and economic justification. Each featured engagement includes the observed percentage uplift, main loss drivers, and the recommended action path. The portfolio illustrates that small, well-targeted changes often produce reliable annual gains while larger retrofits are reserved for sites with clear, long-term benefit. If you would like a project analysis tailored to your site, request a screening and we will outline likely gains and a staged implementation plan.
Project gallery and outcomes
This gallery presents a cross-section of our most illustrative engagements. Each card explains the loss driver, the intervention, and an observed or modeled improvement in production. Projects include a commercial rooftop where module optimizers recovered production lost to intermittent shade, a residential array where inverter tuning reduced midday clipping and improved monthly yield, and a ground-mounted field where evidence-based cleaning reduced soiling losses significantly. We include images that reflect real field conditions so owners can compare contexts and identify the scenarios most like their own. The gallery focuses on transparency and measurable change, not on branding. If a project looks relevant, we will provide a concise screening that estimates expected uplift and payback for a similar site.
Residential - inverter tuning
Issue: Midday clipping and mismatch. Solution: inverter MPPT window adjustment and string balancing. Outcome: smoother daily production and increased midday harvest by 7 percent.
Utility-scale - soiling control
Issue: Dust and pollen accumulation in arid season. Solution: data-driven cleaning schedule and anti-soiling trials. Outcome: 18 percent reduction in soiling losses annually.
Case study: measured uplift and verification
Each case includes a measurement and verification plan that defines baseline periods, performance metrics, and statistical confidence intervals for observed uplift. We analyze historical SCADA or monitoring data to create a baseline, accounting for weather and operational changes. After implementation we run a post-commissioning analysis over a defined verification window to quantify actual gains. Where appropriate, we apply normalized performance metrics to adjust for irradiance and temperature differences between baseline and verification windows. Deliverables include charts, delta tables, and an executive summary that maps technical actions to economic outcomes. This rigorous verification ensures owners and asset managers have confidence in realized improvements and can make better capital allocation decisions.
