Common Mistakes And Misconceptions
| Mistake/Misconception | Correct Viewpoint |
|---|---|
| Solar panels can power my home even during a blackout. | While solar panels generate electricity from the sun, they cannot provide power to your home during a blackout unless you have a battery backup system installed. Without a battery backup, your solar panels will automatically shut off when the grid goes down for safety reasons. |
| All battery backups are created equal. | There are different types of batteries available for solar systems, and each has its own advantages and disadvantages in terms of cost, lifespan, capacity, and performance under various conditions (e.g., temperature). It’s important to choose the right type of battery that meets your specific needs and budget. |
| I don’t need a battery backup if I’m connected to the grid. | Even if you’re connected to the grid, having a battery backup can still be beneficial in several ways: it can reduce your reliance on fossil fuels by storing excess energy generated by your solar panels; it can help you save money on utility bills by using stored energy during peak hours or when rates are high; it can provide peace of mind knowing that you have backup power in case of an outage or emergency situation. |
| Battery backups are too expensive and not worth the investment. | While it’s true that installing a battery backup system adds extra costs upfront, it may actually save you money in the long run depending on factors such as electricity rates, usage patterns, incentives/rebates available in your area, etc. Additionally, having reliable backup power is invaluable especially if you live in an area prone to blackouts or natural disasters where access to electricity is critical for safety and comfort. |
| A bigger battery means better performance regardless of other factors. | The size (capacity) of your battery should be based on several factors including but not limited to: how much energy you use daily/weekly/monthly/yearly, how much energy your solar panels generate, how often you experience power outages or grid disruptions, and what appliances/devices you want to power during an outage. A bigger battery may not necessarily be better if it exceeds your needs or budget. |
