Technical FAQs 4

How do I choose a home solar storage system?

When selecting a home solar storage system, consider factors such as electricity consumption, solar power capacity, battery size, discharge depth, and inverter power. Blue Carbon offers high-efficiency solar + energy storage solutions, helping households achieve energy independence, reduce electricity costs, and enjoy sustainable clean energy.

What is energy storage?

Energy storage is a system that can help more effectively integrate solar into the energy landscape. Sometimes it is co-located with, or placed next to, a solar energy system, and sometimes the storage system stands alone.

Why is solar storage important?

Solar storage is important because it allows solar energy to contribute to the electricity supply even when the sun isn’t shining. It also helps smooth out variations in solar energy flow on the grid, which are caused by changes in sunlight.

What size solar panels & batteries do I Need?

For a stable and efficient home solar storage system, proper sizing of solar panels and batteries is essential. If a household consumes 8kWh per day, with an average of 5 hours of sunlight and 85% solar efficiency, the required solar panel capacity is: 8kWh÷ (5×0.85)≈1.88kW8kWh \div (5 \times 0.85) \approx 1.88kW8kWh÷ (5×0.85)≈1.88kW
