    Case Study · Commercial Solar + Storage

    A strategic upgrade with financial upside.

    A commercial solar + storage investment brief, built for property managers, REITs, and institutional owners. Solar is no longer just a sustainability choice, it's a strategic financial move.

    184 kW solar · 60 kW battery · $5,901/mo saved · 3.8-year ROI · 25.3% IRR · $2.05M NPV · 
    184 kW solar · 60 kW battery · $5,901/mo saved · 3.8-year ROI · 25.3% IRR · $2.05M NPV · 

    Whether you're a property owner, asset manager, REIT executive, or overseeing a large portfolio, the math matters: if your goals include increasing NOI, preserving income, boosting valuations, or hedging against utility inflation, solar delivers on all fronts. At GBS, we specialize in helping institutional clients transform utility liabilities into income-generating assets with solar + battery installations.

    Why it matters to owners and managers

    →Increase NOI. Roll utility costs into rent at a steady 3% annual increase while actual utility costs rise 8 to 12%.
    →Elevate asset value. Stabilized cash flows improve cap rates and asset pricing.
    →Monetize utility infrastructure. Pass energy costs to tenants with built-in margin.
    →Simplify tenant billing. Predictable, bundled rents improve satisfaction and reduce complaints.
    →Support ESG goals. Clean-energy installations drive measurable, reportable sustainability gains.
    →Beat energy inflation. Lock in electric rates internally and pass them through with a 3% escalator.
