Solar PV String Sizing – 550W Module Example”

---

1️⃣ Overall Design Identity (Engineering Authority Theme)

🎯 Style Direction

• Clean

• Technical

• Minimal

• Data-focused

• Professional (EPC-level)

🎨 Color Palette (Solar + Engineering)

Purpose	Color	HEX
Primary	Deep Navy Blue	#0A2540
Accent	Solar Orange	#F5A623
Highlight	Emerald Green	#1DB954
Background Light	#F4F6F8
Text Dark	#1C1C1C

Use maximum 2–3 colors per slide to keep it premium.

---

2️⃣ Slide Layout Structure (Consistent Framework)

Use a 3-Zone Grid System on every slide:

🔷 Top Strip (10–15%)

Small header bar (Navy background)

Example:
SOLAR STRING SIZING | ENGINEERING EXAMPLE

---

🔷 Middle Section (65%)

Main content
Big bold headline
Formula or calculation
Key numbers highlighted in orange

---

🔷 Bottom Section (20%)

Footer line:

Pravendra Kumar Rajpoot
Solar QA | EPC Engineering Consultant

Keep it small and subtle.

---

3️⃣ Slide-by-Slide Visual Structure

---

🟦 Slide 1 – Hook Slide

Background:

Full Navy Blue

Layout:

Large White Text (Centered)

ARE YOU SIZING SOLAR STRINGS CORRECTLY?

Below in orange:
Temperature Can Damage Inverters ⚡

Add subtle:
Solar panel vector outline in background (opacity 10%)

---

🟦 Slide 2 – Problem Slide

Background: White

Left Side:
Bullet points (Dark text)

Right Side:
Small icon stack:
❄️ Cold
🔥 Heat
⚡ Inverter

Highlight keywords in Orange:
Maximum Voltage
Minimum MPPT

---

🟦 Slide 3 – Given Data Slide

Use “Specification Card” Layout

Create 2 boxes side-by-side:

Box 1 – Module Specs

550W Module
Voc = 49.5V
Vmp = 41.2V
Temp Coeff = –0.28%/°C

Box 2 – Inverter & Site

Range = 200–1000V
Min Temp = –5°C
Max Temp = 45°C

Box Border Color: Navy
Key values: Orange

---

🟦 Slide 4 – Voc Correction Slide

Use Formula Highlight Box

Inside centered box:

ΔT = 30°C

Voc = 49.5 + (0.0028 × 30 × 49.5)

Final Result (Large Font, Green):

53.66V

Below in small grey:
Corrected Voc at –5°C

---

🟦 Slide 5 – Max Modules Slide

Split Layout:

Left:
Formula

1000V ÷ 53.66V

Right:
Big Bold Number:

18 Modules

Use Green Check icon next to it.

---

🟦 Slide 6 – Vmp Correction Slide

Background: Light Grey

Centered Formula Box:

Vmp = 41.2 − (0.0028 × 20 × 41.2)

Final in Green:

38.9V

Add small flame icon 🔥 top corner.

---

🟦 Slide 7 – MPPT Check Slide

Large Bold Math:

38.9V × 18 = 700V

Below:

700V > 200V

Add:

✔ SAFE FOR MPPT RANGE

Use Green highlight for SAFE.

---

🟦 Slide 8 – Final Summary Slide

Use Table Layout

Create clean 2-column summary:

Corrected Voc → 53.66V
Max Modules → 18
Corrected Vmp → 38.9V
String Voltage → 700V
Status → SAFE

Make “SAFE” in Green.

---

🟦 Slide 9 – Common Mistakes Slide

Dark Blue Background

White Text:

Common EPC Mistakes:

❌ Using STC voltage directly
❌ Ignoring cold condition
❌ Not checking MPPT lower limit

Use red icons for mistakes.

---

🟦 Slide 10 – Authority Slide

Centered Quote Style:

“String sizing is temperature-based voltage engineering.”

Add subtle underline in orange.

---

🟦 Slide 11 – CTA Slide

Background: Gradient (Navy → Dark Blue)

Large Text:

Want the Automated Excel String Tool?

Below:

Comment “STRING TOOL”

Add small dashboard icon.

---

4️⃣ Typography Guide (Canva)

Heading Font:
Montserrat ExtraBold

Subheading:
Poppins SemiBold

Body:
Open Sans

Numbers:
Make 20–30% larger than body text.

---

5️⃣ Visual Hierarchy Rule (Very Important)

Every slide should have:

1 Big Idea
1 Formula or Key Concept
1 Highlighted Result

Avoid clutter. Engineers respect clarity.

---

6️⃣ Advanced Professional Touch

✔ Use grid alignment
✔ Keep equal margins
✔ Maintain same footer position
✔ Use subtle shadow on formula boxes
✔ Keep slide background consistent
