Methodology

Measuring the Real Economics of Residential Solar Assets.

Beyond Solar Production

Most solar systems are evaluated using energy metrics: production, exports, self-consumption and uptime.

Râ Metrics focuses on economics.

We measure how solar production translates into realized household cashflow and financing coverage.

Full Grid Cost
− Residual Imports
+ Export Revenues
− Loan Repayment
= Solar P&L

Solar P&L represents the realized monthly economic outcome of a solar installation.

(Full Grid Cost - Residual Imports)
/ Full Grid Cost

Measures the proportion of electricity costs effectively replaced by solar generation.

A Râ Efficiency of 80% means the installation replaced 80% of the electricity costs that would have been paid without solar.

(Full Grid Cost - Residual Imports)
/ Loan Repayment

Measures whether the economic value generated by the installation covers its financing obligation.

A Coverage Ratio above 1x means the installation generates more value than required to repay its loan.

Understand whether a solar installation generates positive economic value.

Assess the realized financing coverage of solar-backed loans.

Analyze the realized economics of solar-financed asset portfolios.
