A rigid solar panel is the most common panel on the market and is composed of monocrystalline or polycrystalline cells with a layer of protective tempered glass and an aluminum frame. These units are very durable and are used in almost all applications with flat surfaces. Our rigid panels range from 30 Watts to 200 Watts.

  • Can I connect and charge my battery directly with the solar panel?

    We do not recommend using the solar panel without the charge controller. Using solar panel without the charge controller might damage the batteries.

  • Can I connect two different size panels together?

    We recommend connecting the same size and wattage panels together to limit any efficiency loss.

  • Can I drill holes to the aluminum frame for mounting?

    We do not recommend drilling any new holes to the aluminum frame of the panel as it could damage the internal circuit and solar cells. (Also, any modification to the panel will void the warranty). We recommend only using the pre-drilled holes for mounting.

Care and Performance:

  • Do solar panels require maintenance/Can I wash my solar panel?

    Solar panels generally require very little maintenance. We recommend cleaning the solar panel with water, glass cleaner (Windex) and microfiber cloth.

  • Will my panel produce power in an overcast condition?

    The amount of solar energy panels can generate depends on sunlight. Even on a cloudy day, the solar panels will produce some energy.

  • Will my panel produce power if covered with snow?

    The Solar panels cannot produce electricity if covered with snow.

  • What is the best direction for solar panel to face?

    The best direction to face solar panel is South.
