Solar panels are used as part of the top covering material of the greenhouse to build a greenhouse for fish and vegetable symbiosis. For the fish farming part, there is no need to consider the top of the light, so solar panels can be used. The remaining space can be used to grow vegetables in a hydroponic way. Hydroponic vegetables can not only use the fertilizer of the water for fish farming, but also save energy. Here are some specific functional introductions
Structural aspects Modular top partition The top of the fish farming area can be completely covered with solar panels, which can replace the top covering material of the greenhouse and be installed at an angle to increase the power generation efficiency. An insulation layer can be installed under the photovoltaic panel to reduce water temperature fluctuations. Top of the planting area: transparent materials (glass or polycarbonate board) are used to ensure uniform lighting. Space utilization Vertical hydroponic planting: Use NFT (nutrient film technology) or vertical racks in the planting area to grow low leafy vegetables such as lettuce and spinach to maximize space utilization. Fish pond: Cultivate dense varieties such as tilapia to increase profits.
Energy system
Solar panels
Traditional solar panels can be selected for the fish farming area, which have high power generation efficiency. Photovoltaic glass with light transmittance can be selected for the planting area. It can generate electricity without completely blocking sunlight. Energy storage and electricity consumption matching Battery capacity: Energy storage is configured at twice the daily average power generation (water pumps in the fish farming area require electricity at night, and the power demand of the filtering device). Circuit supply design: Electricity is first supplied to key equipment such as water pumps, air pumps, and microfilters, and the remaining electricity is used for supplementary lighting or heating.
Ecological cycle Water and fertilizer coordinated management Fish-vegetable ratio: Every 1kg of fish daily excrement can support the growth of about 5-10㎡ leafy vegetables (the data here is a reference to tilapia farming data). For example, 1,000 tilapia (average weight 0.5kg) → daily excrement is about 2.5kg → can support 25-50㎡ hydroponic vegetables. Water quality assurance The self-developed integrated microfilter ensures water quality in the entire system. The water path is: fish pond → microfilter (solid fertilizer removal, water nitrification) → planting bed → return to fish pond.
