Our educational content is organized around the questions homeowners face at each stage of the solar journey, from initial curiosity to post-installation ownership.
Grid-Tied Systems
The most common configuration for residential solar. Your system connects to the utility grid, feeding excess electricity back and drawing from the grid when production falls short. No batteries required.
Understanding how your local net metering arrangement works is essential for evaluating whether a grid-tied system makes sense for your energy pattern. Not all utility areas offer the same terms.
- How bi-directional meters measure your import and export
- What happens during a grid outage with a standard grid-tied setup
- How to read your utility bill after going solar
- Feed-in tariff structures and how they vary
Hybrid Systems
Hybrid systems combine grid connection with battery storage. Excess solar energy charges the battery first, then exports to the grid. During outages, the battery can supply your home independently.
The added complexity comes with added cost and additional components to understand. Battery capacity, inverter compatibility, and backup configuration all matter significantly in system design.
- How hybrid inverters manage multiple energy sources
- Battery capacity sizing for your actual usage patterns
- What backup power configurations are realistic
- Lifespan and cycle expectations for home battery systems
Off-Grid Systems
Systems designed to operate entirely without grid connection. These require careful sizing for worst-case winter production and full household loads, along with substantial battery capacity and often a backup generator.
Off-grid is genuinely complex. We cover the concepts thoroughly so you understand what is involved before evaluating whether it applies to your situation.
- Load analysis: calculating your actual energy needs
- Generator integration and when it matters
- Charge controller types and their role
Understanding panel technology
The market offers more cell technologies than it did even a few years ago. Here is what differentiates them.
Monocrystalline (Mono)
Made from a single silicon crystal. Uniform dark appearance. Higher efficiency than polycrystalline and better performance in low-light conditions. Currently the dominant technology in residential installations.
PERC Technology
Passivated Emitter and Rear Cell. An advancement over standard monocrystalline that adds a reflective layer at the back of the cell, capturing light that would otherwise pass through. Improved output at a relatively modest cost premium.
TOPCon Technology
Tunnel Oxide Passivated Contact. Reduces electron recombination at the cell surface, pushing efficiency higher than standard PERC. Increasingly common in residential installations as manufacturing scales up.
Heterojunction (HJT)
Combines crystalline silicon with amorphous silicon layers. Excellent temperature coefficient means less performance loss in heat. Lower degradation rates. Currently at a higher price point than TOPCon but increasingly competitive.
Reading a proposal with confidence
A solar installation proposal typically runs several pages and contains technical specifications, financial projections, and warranty information. Knowing how to read it changes the conversation entirely.
We walk through each section of a typical proposal: what the numbers mean, how to verify the production estimates, and which contract clauses deserve legal review before signing.
Ask a QuestionPanel model, inverter model, system size in kWp, and installation details should all be explicit, not summarized.
Look for software-generated yield estimates with the tool name and input assumptions listed. Handwritten projections are a concern.
Separate product warranties (panels, inverter, battery) from the installer's workmanship warranty. All should have explicit terms and durations.
Payments tied to installation milestones protect you. Large upfront payments before any work begins are worth questioning.
