لوحة الضوئية
هنا نحن نبحث عن السلطة (الذروة، أعرب في W) من الألواح الشمسية التي سيتم تركيبها لتلبية الاحتياجات الخاصة بك وفقا لموقعك الجغرافي. الصيغة هي كما يلي:
Pp = Dn / (Yb X Yi X Rd)
- Pp (Wp) : Peak power (goal)
- Dn (Wh/d) : Daily needs = 240
- يب: العائد الكهربائي للبطاريات 0.85
- يي: العائد الكهربائي للتركيب المتبقية (وحدة تحكم المسؤول، ...) = 0.87
- Rd : average daily radiation of the worst month in the plane of the panel (kWh/m²/d)
- According to data from PVGIS, the value for the selected location is 0.95022 kWh/m²/d
في حالتك، والنتيجة هي :
إخفاء العملية
Pp = 240 / (0.85 * 0.87 * 0.95022) = 342 W
الألواح الكهروضوئية تنتج الكهرباء من أشعة الشمس (الإشعاع الشمسي).
According entered data, 342W of solar panel are required to fulfill your daily needs of 240Wh/d.
انظر، فهم الإجراء، والحساب
One possibility could be to have 1 panel(s) monocristalin of 360W each (?). Which extend the unit capacity to 360W
Batterie
We are looking here for the nominal capacity expressed in ampere per hour (Ah, given in C10)
Cap = (Dn x Aut) / (DD x U)
في حالتك، والنتيجة هي :
إخفاء العملية
Cap = (240 x 3) / (0.3 x 12) = 200 Ah
Batteries are used to store electric energy produced by the panels. You will need a battery plant of 200 Ah at 12 V.
انظر، فهم الإجراء، والحساب
A wiring hypothesis would be to have 1> GEL 12V 250Ah type batteries, which increases the plant capacity up to 250Ah
متحكم الشحن
وحدة تحكم المسؤول تقف بين البطاريات واللوحات، ودورها هو التعامل مع شحن البطاريات اعتمادا على ما يمكن أن توفر لوحات.
A wiring hypothesis would be to have a MPTT 250/65 type charge controller(?) التي سيتم توصيلها 1 فريقفريق
A type MPTT 250/65 charge controller, with a 12V battery plant, allows :
- 860W max panel power :
- With a total of 1 360W panel(s), we reach 360W (?)
- 250V max PV voltage of open circuit :
- With 1 serialized panel(s) of 47V of (Voc) voltage and a 20% security margin, we reach 56V (?)
- 30A max PV short-circuit current :
- With 1 parallel panel(s) having 10A intensity (Isc) and a 10% security margin, we reach 11A (?)
ملاحظة: التسلسل يتضاعف الجهد (V) وموازنة تتضاعف شدة (I)
All these characteristics are available in the product's technical sheet. You can customize your charge controller characteristics in Export mode.

Cable diagram
تم إنشاء مخطط الأسلاك وفقا لفرض لوحة / تهمة تحكم / البطارية:
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.
وحدة تحكم البطارية
فمن المستحسن أن يكون كونتروليور البطارية من أجل التحقق من حالة شحن البطارية البطارية.
الأسلاك
Wire section choice ( calculate) is important in order to avoid electricity lossess :
- Between panels and charge controller, for a distance of 8m, a 6mm² section cable is recommended (انظر، فهم الإجراء)
إخفاء العملية
الصيغة لحساب قسم الأسلاك من أجل تجنب الخسارة هي :
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) : admitted wire level voltage loss (1% of voltage)
- (panels voltage * number of series) * 1/100
In our case it gives :
S = 0.019 x (8x2) x 10 / 0.47 = 6.47mm²
- Nearest wire section suggested : 10mm², approximate cost 16€
- Between charge controller and batteries, for a 1.5m distance, a wire section of 14.25mm² is recommended (انظر، فهم الإجراء)

- 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) : admitted wire level voltage loss (1% of voltage)
- Batteries voltage, i. e. 12V * 1/100
In our case it gives :
S = 0.019 x (1x2) x (360 / 12) / 0.12 = 14.25mm²
- Nearest wire section suggested : 16mm², approximate cost 6€

Budget
_('This is an approximate estimation for new equipment, it can\'t be considered as a quote.') ?>
- لوحة الضوئية : between 234€ and 396€ (?)
- Batterie : between 540€ and 852€ (?)
- متحكم الشحن : approximately 700€
- Converter : between 70€ and 85€ (?)
- وحدة تحكم البطارية : approximately 150€
- Wiring : approximately 23€
Which brings to a total budget between 1717 and 2206€. Cost of panels support, wire, wire terminal and protection elements (fuse, battery cut-off, ...) is not included.
