Is It Possible To Power a Household Only Using Solar Power?
The short answer to this question is Yes. You can completely power or run your household using solar power. However, it does require some investment. If you are ready to invest, yes, solar energy can indeed power your household day and night.
How Does Solar Energy Work?
Solar power works when solar panels capture sunlight (photons) and break them down to electrons. This free flow of electrons is what we call electrical energy. This electrical energy, in turn, powers all the electric and electronic devices and appliances of the household.
A home solar power system typically consists of solar panels, solar inverters, and some may also use a solar battery. Solar batteries are a must-have if you want to go fully solar as they serve as an energy backup. So, what do solar inverters do? Solar inverters convert the generated solar energy from DC to AC, the only way to power a household.
Different Types of Solar Systems
You should know about the different solar systems first to get a rough idea of how solar PV systems can power your home.
1. On-Grid Solar System
On-grid electricity is a grid supported solar power system. It means the system only works when it is connected to the grid. So, if there is a power outage, the grid-connected solar system will not power your home. In this system, the unused excess electricity is automatically fed back to the grid, and in turn, you receive a feed-in tariff that’s fixed by your electricity provider.
2. Off-Grid Solar System
An off-grid solar system is free from the grid, and hence you can call it a stand-alone or battery-powered solar system. In this system, the solar batteries act as backup energy to power a household at night or at times of poor sunlight.
3. Hybrid Solar System
A hybrid solar system is a combination of both on-grid and off-grid solar power systems. In this system, the excess energy is first used to charge the solar batteries, and once they are fully charged, the rest is automatically exported to the grid. You can power your household using a hybrid solar system even when there is a blackout.
What Are the Major Considerations?
Now that you know about the different types of solar power systems, now let’s look into the various conditions to consider before going fully solar.
- How much sunlight do you get? This depends on the peak sunlight hours and also the daylight hours. A peak sun hour is an hour at which the intensity of the sunlight reaches an average of 1000 watts per square meter. Though solar panels will still produce solar power when the weather is cloudy or rainy, maximum output is only when the sun shines directly over them. So, it is essential to consider the climatic conditions and roof orientation to go fully solar.
- What is your daily energy consumption rate? Your energy requirement matters to determine the number of solar panels needed to power your house. It’s because solar panels are available in different sizes and power outputs, so you need to choose the right one for your needs.
- Are solar batteries sufficient to power you at night? Many homeowners doubt the efficiency of solar batteries when compared to on-grid systems. Perhaps, this is the most critical factor to consider if you are going fully solar. Though solar batteries provide complete energy independence from the grid, having an efficient and adequate solar power system can be a big investment with a solar battery.
