Are you tired of dealing with frequent power outages or simply looking for ways to cut down on your electricity expenses? Solar combos are the ultimate solution. Not only do they offer a reliable power source when you need it most, but they’re also a smart financial investment. Plus, they contribute positively to the environment, making them the energy choice of the future.

If you're considering investing in a solar combo, you’ve come to the right place. This comprehensive guide will walk you through everything you need to know to purchase the perfect solar combo for your home.

Understanding Your Power Needs

Before diving into the specifics, it’s essential to calculate your power requirements accurately. This involves determining the total energy needed to keep your critical appliances running during a power outage. Whether it's your refrigerator, computer, lights, or television, identifying the devices you absolutely cannot live without is the first step.

Step-by-Step Guide to Calculating Power Requirements

Once you've listed your necessary appliances, follow these steps to determine your power needs:

  1. Calculate the total power consumption in watts for all your chosen appliances.
  2. Multiply the total wattage by 1.67 to find the appropriate UPS VA rating.
  3. Select a battery voltage that matches the UPS specifications.
  4. Divide your daily energy requirements by three to estimate the size of the solar panel you’ll need.

Let’s illustrate this with an example:

Appliance Power Rating (Watts) Quantity Total Load (Watts) Hours of Use Per Day Daily Energy Consumption (Wh)
Television 100 1 100 2 200
LED Lights 10 3 30 2 60
Fan 60 4 240 2 480
Tube Lights 40 3 120 2 240
Total Load 490 980

From here, we can calculate the UPS rating:

UPS VA rating = Total load (490) x 1.67 = 818.3 VA.

Thus, an 850 VA UPS would be ideal for this setup.

Battery Size Selection

For an 850 VA solar UPS, you’ll need a 12V battery with a current rating of 30 amperes.

Battery AH = (1.9 x Total daily Watt-hours) / (Number of batteries x 12) = (940 x 1.9) / (12 x 1) = 155 AH.

So, a 150 AH solar battery would be the right choice.

Solar Panel Size

The solar panel size can be determined by dividing your daily energy usage (in watt-hours) by three.

In this case, the panel size would be 326.7 W, i.e., 980/3.

Since the UPS supports a 12V system, you’ll need 12V panels with a capacity of either 100Wp or 150Wp.

For this, you could install three 100Wp panels in parallel or two 150Wp panels in parallel.

Inverter Type

Choosing the correct inverter is vital as it converts the DC generated by the panels into usable AC. String inverters are cost-effective but less efficient, while MLPEs (module-level power electronics) are more efficient but pricier. Opt for string inverters if you’re in a location with abundant sunlight; otherwise, consider MLPEs for better performance.

Selecting the Right Installer

Choosing a reputable installer is equally important. Research their credentials, certifications, and past projects before making your decision. A trustworthy installer ensures proper installation and maintenance, extending the lifespan of your solar combo.

Additional Considerations

When evaluating solar combos, consider factors like panel efficiency (industry average is 16-18%) and warranty duration (typically 10-25 years). Ensure your combo aligns with these standards. Additionally, check the durability, brand reputation, and expected longevity of the product.
