This Sunjoy solar carport with an energy storage module is an innovative and sustainable solution for harnessing solar energy to power electric vehicles. This structure combines the benefits of solar panels with a carport design, providing shade for vehicles while generating clean, renewable energy.

The integrated solar panels and the battery energy storage system allow the self-generation and self-consumption of electricity simultaneously and manage separate peak and valley arbitrage. Additionally, suppose the photovoltaic power generation is greater than the amount of electricity consumed by the loads. In that case, surplus electricity can be sold back to the local grid, to make a profit.

When local electrical costs are lowest: purchase electricity from the grid to charge the energy storage system, then utilize this stored power to supply loads during peak electric-cost periods (ultimately saving money for users).

Features

• Durable Materials: Constructed with a durable black powder-coated steel frame and sturdy solar panel roof, to protect your vehicles, trailers, boats, and outdoor equipment all year long.
• Sturdy & Stable Construction: Six 4.6 x 4.6 in. powder-coated steel posts with ground stakes secure the metal solar carport to the ground to withstand strong winds, creating durability and stability for years to come.

• Balanced Roof Slope Design: The balanced roof slope design prevents rainwater from massing while also distributing the pressure from any snow cover.

• Natural Wood Grain Finish Steel Frame: The sturdy steel frame with a natural-looking wood grain finish, that is not easy to rust and peel and will stand the test of time.
• HJT 3.0: Combining the gettering process and double-sided surface to maximize cell efficiency and module power.
• -0.26%/°C Pmax Temperature Coefficient: More stable power generation performance and even better in the hot climate.
• Small Chamfer Design: A bigger power generation area on the solar cell, increasing 1% cell power of a single piece.
• Smbb Design with Half-Cut Technology: Shorter current transmission distance, less resistive loss, and higher cell efficiency.
• Up to 90% Bifaciality: Natural symmetrical bifacial structure bringing more energy yield from the backside.
• Sealing with Pib-Based Sealant: Stronger water resistance, and greater air impermeability to extend module lifespan.
• Higher Reliability: Industry-leading product and performance warranty, ensuring modules’ consistent outstanding performance.
