A solar PV system doesn’t need a battery to run as it should, but this optional extra could come in useful. The battery store power up that you aren’t using at the time, making use of the extra energy your solar PV system is absorbing so it doesn’t go to waste and then holding onto it for later use.
That can come in very useful, and if you are not sure if you need a battery for your PV system, here are a few reasons why you want to.
- Conservation of Energy
If you are the kind of person who cares about not letting good resources go to waste and you can’t stand the thought of your solar power system just letting good energy be expended without anyone getting to use it, then a battery could be a good investment.
Having a storage battery hooked up to your PV system means that you are using most or all of the energy that passes through it, putting it to good use.
2. Never Run Out of Power (Probably)
The main reason that homeowners will purchase a storage battery to go with their PV solar system is to make sure that they always have power on hand to draw from. Some days, the sun will send more energy to your system than others.
If the weather is cloudy or rainy, your system might not get much sunshine that day, so your power could run out. The battery can store excess energy from sunny days so that you have it on hand for when you need it.
It’s possible that you might not always have power saved up even if you do have a battery (like if the weather is poor for days in a row), but you’re certainly less likely to run out of power when you need it.
3. Can Save You Money
If you have a hybrid power system, where some of your power is supplied by the PV system and some is supplied by the power company, a solar storage battery could keep your electric bill low.
When you run out of power from the PV system, your power generation then comes from the electric company, driving up your costs. If you have a storage battery installed, however, you can continue to get power from the PV system and not have to rely on government-provided power.
Despite the initial costs of the battery, it can pay for itself in time.
4. For Backup Generator Owners, You’ll Save Resources
If you live off the grid and utilize a backup generator, you won’t have to use valuable fossil fuels to get energy from your generator as often if you have a storage battery installed.
Your generator will experience less wear and tear as well. You can do your part to conserve fossil fuels and protect the environment by making an investment in a solar storage battery.
5. It Gives You Flexibility
Your current PV system setup may be adequate for now, but what if your power consumption needs change? If you have a new addition to your family or you have guests staying over for a while, you will benefit from the added power supply that a battery provides.
You can plan for the future and give yourself some options by having a storage battery ready to go, and you may just find that it comes in useful more often than you would expect.
