太陽光発電パネル
ここでは、電源を探しています (ピーク, W で表現) 太陽電池パネルからあなたの地理的な場所に応じてお客様のニーズを満たすためにマウントする. 式は以下の通りです :
Pp = Dn / (Yb X Yi X Rd)
- Pp (Wp) : Peak power (goal)
- Dn (Wh/d) : Daily needs = 240
- Yb : 電池の電気収穫 0.85
- Yi : electrical yield for the remaining installation (charge controller, ...) = 0.87
- Rd : パネルの平面の最も悪い月の平均毎日の放射 (kWh/m²/d)
あなたの場合、結果は :

Pp = 240 / (0.85 * 0.87 * 0.8) = 406 W
Photovoltaic panels produce electricity from sunlight (solar radiation).
According entered data, 406W of solar panel are required to fulfill your daily needs of 240Wh/d.
See, understand the procedure, the calculation
One possibility could be to have 2 panel(s) monocristalin of 240W each (?). Which extend the unit capacity to 480W
電池
We are looking here for the nominal capacity expressed in ampere per hour (Ah, given in C10)
Cap = (Dn x Aut) / (DD x U)
- Cap (Ah) : Nominal capacity of batteries (in C10))
- Dn (Wh/d) : Daily needs = 240
- Aut: Autonomous days amount (no sun) = 4
- DD (%) : 最大吐出率 = 30
- U (V) : 最終電池工場の電圧 = 12
あなたの場合、結果は :
プロセスを非表示にする
Cap = (240 x 4) / (0.3 x 12) = 267 Ah
Batteries are used to store electric energy produced by the panels. You will need a battery plant of 267 Ah at 12 V.
See, understand the procedure, the calculation
A wiring hypothesis would be to have 2> GEL 12V 150Ah (165Ah en C20) type batteries, which increases the plant capacity up to 300Ah
Charge controller
充電コントローラは電池とパネルの間に立って、その役割は、パネルが提供できるものに応じて電池の充電を処理することです.
A wiring hypothesis would be to have a MPTT 250/65 type charge controller(?) on which would be connected 2 serialized panels
A type MPTT 250/65 charge controller, with a 12V battery plant, allows :
- 860W max panel power :
- With a total of 2 240W panel(s), we reach 480W (?)
- 250V max PV voltage of open circuit :
- With 2 serialized panel(s) of 43V of (Voc) voltage and a 20% security margin, we reach 103V (?)
- 30A max PV short-circuit current :
- With 1 parallel panel(s) having 7A intensity (Isc) and a 10% security margin, we reach 7A (?)
Note: serialization multiplies voltage (V) and paralleling multiplies the intensity (I)

Cable diagram
A wiring diagram was established according to panel/charge controller/battery hypothesis :
Converter
The converter goal is to transform batteries DC current (here 12V) in AC current usable for standard devices. You need a converter able to deliver the 10W max electric power you need.
An hypothesis would be to choose a 12/180 type converter that goes up to 175W max power with possible peaks at 350W.
バッテリ制御
It is recommended to have a bettery controleur in order to check battery plant charge state.
The wiring
Wire section choice ( calculate) is important in order to avoid electricity lossess :
- Between panels and charge controller, for a distance of 8m, a 2mm² section cable is recommended (see, understand the procedure)

損失を避けるためにワイヤセクションを計算する数式は :
S = Rho x L x I / VL
- S (mm²) : Wire section
- Rho (ohm) : Wire resistivity (0,017ohm for copper)
- L (m) : back and forth wire length
- I (A): Intensity (here panel intensity multiplied by the number of parallel)
- VL (V) : 認められたワイヤーレベルの電圧損失 (1% 電圧の)
- (panels voltage * number of series) * 1/100
In our case it gives :
S = 0.019 x (8x2) x 7 / 0.86 = 2.47mm²
- Nearest wire section suggested : 2,5mm², approximate cost 8€
- Between charge controller and batteries, for a 1.5m distance, a wire section of 19mm² is recommended (see, understand the procedure)

損失を避けるためにワイヤセクションを計算する数式は :
S = Rho x L x I / VL
- S (mm²) : Wire section
- Rho (ohm) : Wire resistivity (0,017ohm for copper)
- L (m) : back and forth wire length
- I (A): Intensity (here the power of the panels / the voltage of the battery bank)
- VL (V) : 認められたワイヤーレベルの電圧損失 (1% 電圧の)
- Batteries voltage, i. e. 12V * 1/100
In our case it gives :
S = 0.019 x (1x2) x (480 / 12) / 0.12 = 19mm²
- Nearest wire section suggested : 25mm², approximate cost 8€

予算
_('This is an approximate estimation for new equipment, it can\'t be considered as a quote.') ?>
- 太陽光発電パネル : between 312€ and 528€ (?)
- 電池 : between 648€ and 1022€ (?)
- Charge controller : 約 700€
- Converter : between 70€ and 85€ (?)
- バッテリ制御 : 約 150€
- Wiring : 約 17€
Which brings to a total budget between 1897 and 2502€. Cost of panels support, wire, wire terminal and protection elements (fuse, battery cut-off, ...) is not included.
