Residential Solar Consulting in San Jose and Silicon Valley

Helping Homeowners Navigate Solar Decisions

Residential solar projects represent a major commitment for most households. Between selecting installers, evaluating system sizes, understanding the impact of California's NEM 3.0 Net Billing tariff, and configuring battery backup capacities, the process can feel overwhelming.

Eco Ray Consulting provides independent, educational consulting to help you evaluate home solar projects objectively. Because we do not sell hardware or perform installations, we focus strictly on your household priorities and roof configurations.

Core Residential Consulting Focus Areas

Understanding Household Electricity Use

We analyze 12 months of PG&E billing statements to identify hourly and seasonal usage patterns. This step ensures system sizing is based on real consumption profiles, not generic guidelines.

Reviewing Roof and Property Factors

We examine the orientation, pitch, and age of your roof using satellite tools. We highlight shading risks from trees or nearby structures and note constraints that might limit panel placement.

Evaluating Proposed System Size

Many systems are oversized or undersized, leading to poor returns. We help you design correct sizing margins, particularly when coordinating future additions like electric vehicles (EVs) or electric heat pumps.

Reviewing Battery Storage & Electric Vehicle (EV) Charging

Under NEM 3.0, pairing solar with battery storage is often a key factor for maximizing power offsets. We review battery capacity options, backup wiring limitations (critical loads panels), and EV charge profiles to ensure system coordination.

Preparing Questions for Providers

We equip you with a tailored list of questions to ask installers regarding removal/re-installation costs for future roof maintenance, code updates, structural details, and warranty processing steps.
