Can a House Run on Solar Power Alone?

Deciding Between Off-Grid vs On-Grid
If your aim is a 100% solar-powered house, you can obtain it with an off-grid or grid-tied solar system. The only difference between these two is what happens to your extra electricity and how you access electricity when your solar system is not producing energy.

On overcast days, rainy climates, or through the night-time, your system won’t produce more electrical energy; however, you’ll still need to make use of it. Solar can still provide you with electrical energy on these occasions by producing extra electrical energy during the sunny periods and that extra electricity is stored in your batteries, in the case of off-grid systems, or it’s transferred back to the electricity grid in exchange for a credit score if you opt for a grid-tied system.

An off-grid solar system is entirely independent of the utility grid. Which means your house won’t be able to draw energy from the utility grid. -However, opting for the off-grid system can be expensive. At the same time, solar batteries continue to come down in price. You’ll be aware of how much solar energy you’re utilizing and how much energy your solar system can store.

With an on-grid solar system, you will be able to generate 100% of the electrical energy your house uses, however, without the need to purchase batteries to store extra energy.

Many states require utility companies to provide net metering or another compensation method for the electrical energy generated by your solar system that’s added to the grid. With net metering, you’ll get a kilowatt-hour credit for each kilowatt-hour you’ve transferred to the grid. You may then use this credit to pay for any electricity you draw from the grid while your solar system is not producing.
