    450W Solar Panel Production in Caracas

    A single 450W solar panel in Caracas is estimated to generate approximately 711 kWh of electricity per year, averaging 1.95 kWh daily. This represents the actual AC power available for your home after system conversion losses.

    Quote readinessThis estimate is strong enough for early planning. A supplier quote still needs roof space, shading, inverter limits, battery needs, and installation constraints.
    Planning notes* To cover 100% of your electricity use (600 kWh/month), we recommend about 11 panels rated at 450W each. Bill savings are capped at your entered use and do not assume export credits.

    Project-ready estimate

    Turn this result into a quote request

    Start with 11 panels at 450W, about 5.0 kW, a 600 kWh/month bill target, and 14% modelled system losses. This gives suppliers the first inputs they need before roof layout, inverter limits, and battery choices are refined.

    Weakest month
    Apr

    56 kWh from one 450W panel; check this month before sizing essential loads.

    Roof fit

    Confirm usable roof planes, shading, inverter limits, and battery needs before accepting a final layout.

    Bill fit

    Adjust panel count and monthly use above so savings are capped to electricity you can offset.

    Quote check

    Ask suppliers to show winter output, assumed losses, and any export-credit value separately.

    Monthly output and winter risk

    The calculator is useful when it shows the weak months, not just a flattering annual number. Use the table to check whether winter output still supports the loads you care about.

    Model basis

    The model uses south-facing panels at 11° tilt, true south orientation, and 14% system loss. Typical 600 kWh/month electricity costs are $0 - $10 (typically $0) using 2024-2025 cost data.
