How Our Solar Calculator Simplifies Your Solar Journey and Provides a Quote
Going solar is now simpler than ever with Bright Solar Solution's Solar Calculator. In this guide, we'll walk you through the easy steps of our calculator, using a 1.4 kW solar system as an example. Whether you're a solar beginner or planning an upgrade, we've got you covered.
Load Details:
Let's take a look at the devices you'll be powering with your solar system:
- Four LED Bulbs: 5 hours/day
- Two Ceiling Fans: 8 hours/day
- One Television: 5 hours/day
- One Refrigerator: 24 hours/day
- One Water Pump: 2 hours/day
- One Router: 24 hours/day
Step 1: Energy Consumption Calculation:
Let's calculate the daily energy consumption for each device and then sum them up:
- LED Bulbs: 4 bulbs * 10W * 5 hours = 200 Wh
- Ceiling Fans: 2 fans * 75W * 8 hours = 1,200 Wh
- Television: 1 TV * 100W * 5 hours = 500 Wh
- Refrigerator: 1 fridge * 150W * 24 hours = 3,600 Wh
- Water Pump: 1 * 500W * 2 hours = 1,000 Wh
- Router: 1 router * 10W * 24 hours = 240 Wh
Total Daily Energy Consumption: 200 Wh + 1,200 Wh + 500 Wh + 3,600 Wh + 1,000 Wh + 240 Wh = 6,740 Wh or 6.74 kWh
Maximum Power Usage in an Hour: 10W + 75W + 100W + 150W + 500W + 10W = 845W
Step 2: Battery Size Recommendation:
With an 8-hour backup in mind, we recommend a battery that can store at least 6.74 kWh or 800 amp. You'll need around 12-volt 200 amp = 4 of these batteries.
Step 3: Solar Panel Size Recommendation:
To generate the power you need, we recommend a 1.4 kW (1400-watt) solar panel system, considering about 6.25 hours of peak sunlight in Dhaka.
Step 4: Inverter Size Recommendation:
For managing your maximum load, such as the refrigerator, we suggest a 1.5 kW inverter.
Step 5: Charge Controller Size Recommendation:
Your solar panel capacity of 1.4 kW requires a charge controller capable of handling 12 volts and 140 amps.
