Abstract

【課題】太陽光発電の一番弱点である曇天、雨天の減衰する発電能力を効率最大時まで引き上げて終日むらなく持続電力を得るソーラー発電システムを提供する。
【解決手段】毎日に於いて太陽電池の発電に最も条件の良い晴天時には余剰電力を蓄電池へ充分に蓄え、日陰、雨天時に即、逆に放電を開始する、このサイクル効果によって発電は最高の条件でインバ−タ−に送電することになる。尚蓄電池に充分容量があれば夜間にも発電機能が働く。
【選択図】図５The present invention provides a solar power generation system that raises the power generation capacity of cloudy and rainy weather, which is the weakest point of solar power generation, to the maximum efficiency and obtains continuous power evenly throughout the day.
SOLUTION: Every day, it is possible to store surplus power enough in the storage battery in fine weather when the conditions are the best for the power generation of solar cells, and immediately start the discharge in the shade and in the rain. Therefore, power is transmitted to the inverter. If the storage battery has sufficient capacity, the power generation function works at night.

Description

本考案は一連のソ−ラ−発電システムをより効率的にするために追加組合せを施したものである。 The present invention provides additional combinations to make a series of solar power generation systems more efficient .

実在する太陽光発電システムは 太陽の光エネルギ−を電気エネルギ−（直流）に変換し、その直流出力をインバ−タ−で交流に変換して商用電力に連係するものである。An existing photovoltaic power generation system converts solar light energy into electrical energy (direct current), converts the direct current output into alternating current with an inverter, and links it to commercial power.

太陽電池は太陽の光を受けて初めて発電するもので曇天や雨天時には極度に能力は低下する、それ故日没には機構上運転は停止する仕組みになっており現状では２４時間の内、実効運転は約１０時間に過ぎず実に高価な割には効率が悪いものである。Solar cells generate power for the first time after receiving sunlight, and their capacities are extremely reduced during cloudy or rainy weather. Therefore, the operation is stopped due to the mechanism at sunset, and currently effective within 24 hours. The operation is only about 10 hours, and it is inefficient for a very expensive operation.

上記課題を解決するため本考案は、太陽電池が発電した直流電力を一旦蓄電池に蓄え、その備蓄した電力をインバ−タ−入力端子へ投入する仕組みである、蓄電池をインバ−タ−容量より余力あるものを設備して置けば曇天、雨天に関係なく安定した電力を全天候、晴天の状態で確保することができる、尚バッテリ−の備蓄電力の続く限り夜間でも、非常時、停電時でもその機能は発揮する。In order to solve the above problems, the present invention is a mechanism for temporarily storing DC power generated by a solar battery in a storage battery and supplying the stored power to an inverter input terminal. If you have something installed, you can secure stable power in all weather and fine weather regardless of cloudy or rainy weather, as long as the battery's stored power continues, its function even at night, emergency, and power outage Will demonstrate.

太陽電池パネルは外気熱により発電効率が変化する、最適の温度は２５度Ｃと言うが真夏の晴天日には表面温度が７０度Ｃにも達し能力は激減し又極度の低温でも影響する、本考案は太陽電池から流れてくる電流を蓄電池に溜めながらインバ−タ−に投入するため不安定な天候でも関係なく安定した電流を作り出すことができる。 The power generation efficiency of solar panels changes due to outside air heat. The optimum temperature is 25 degrees C. However, the surface temperature reaches 70 degrees C on a clear day in the middle of summer, and the capacity is drastically reduced. In the present invention, since the current flowing from the solar cell is stored in the storage battery and input to the inverter, a stable current can be generated regardless of unstable weather.

現在業務用に余剰電力を蓄電して有効利用する設備は既に稼働しているようであるが、この方式は一旦交流電力を作り出した後、莫大な設備で備蓄変換するものである、ここに提案する方式は交流を作る前の段階に組み合わせるもので一般家庭に適用可能で低経費で設置できる。 It seems that facilities that store and use surplus power for business use are already in operation, but this method creates AC power and then converts it to a huge facility, which is proposed here. The method to do is combined with the stage before making the exchange, applicable to ordinary households and can be installed at low cost.
