Whether you're dealing with frequent power outages or simply looking to cut down on your electricity expenses, solar combos offer a practical and sustainable solution. These systems not only serve as a wise financial investment but also provide a dependable source of energy when you need it most. Additionally, solar combos are environmentally friendly, positioning them as the energy solution for the future.
If you’re considering investing in a solar combo, you’ve come to the right place. This comprehensive buying guide will walk you through everything you need to know to purchase the perfect solar combo for your home.
### Power Requirement
Before diving into the specifics of your solar combo, it’s essential to calculate your power needs accurately. Understanding the total wattage required to operate your appliances during a power outage is key to selecting the right system. Start by listing the devices you’d want to keep running—whether it's your refrigerator, computer, lights, fans, or television—and determine their respective power ratings in watts.
#### Steps to Calculate Your Power Requirement:
1. **Sum Up Loads in Watts:** Add up the power ratings of all the appliances you plan to use.
2. **Determine UPS VA Rating:** Multiply the total wattage by 1.67 to get the UPS VA rating.
3. **Select Compatible Battery Voltage:** Choose a battery voltage that matches the UPS specifications.
4. **Calculate Panel Size:** Divide your daily energy requirements by three to estimate the size of the solar panel needed.
Let’s break this down further with an example:
| Equipment | Power Rating (Watts) | Quantity | Load (Watts) | Hours of Usage | Daily Energy Consumption (Wh) |
|----------------|----------------------|----------|--------------|----------------|-------------------------------|
| TV | 100 | 1 | 100 | 2 | 200 |
| LED Bulbs | 10 | 3 | 30 | 2 | 60 |
| Fans | 60 | 4 | 240 | 2 | 480 |
| Tube Lights | 40 | 3 | 120 | 2 | 240 |
| **Total Load** | | | **490** | | **980 Wh** |
Based on the above table:
- **UPS VA Rating**: 490 x 1.67 = 818.3 VA → An 850 VA UPS would be ideal.
- **Battery Size**: For an 850 VA system with a 12V battery, you’d need approximately 155 AH. Therefore, a 150 AH battery would suffice.
- **Solar Panel Size**: To cover 980 Wh daily usage, you’d need a panel size of around 326.7 W. Given the UPS supports a 12V system, you could either install three 100Wp panels in parallel or two 150Wp panels in parallel.
### Choosing the Right Inverter Type
The inverter plays a critical role in converting DC power from the solar panels into usable AC power. Two primary types of inverters exist: string inverters and module-level power electronics (MLPEs). If your location enjoys consistent sunlight, string inverters are generally more cost-effective. On the other hand, MLPEs offer higher efficiency and better performance under less-than-ideal conditions, though they come with a premium price tag.
### Selecting the Ideal Installer
Hiring the right installer is equally important. Research the company thoroughly—look into their past projects, customer reviews, certifications, and licensing status. A reputable installer ensures proper installation and maintenance, which is crucial for the longevity of your solar combo.
### Additional Considerations
When evaluating solar combos, consider the panel efficiency, which typically ranges between 16-18% in the industry. Similarly, warranties usually span 10 to 25 years. Ensure your chosen combo aligns with these benchmarks. Durability, brand reputation, and expected lifespan should also factor into your decision-making process.
