Consumers looking for a backup power source in an electric outage traditionally had gasoline generators as their top choice. A reliable energy source that can be used immediately is required for a backup solution. Has the time come for solar energy and battery storage systems to replace generators, given the recent significant decreases in prices for solar and batteries?
The advantages and disadvantages of both backup energy options will be discussed in this blog.
The cost is the main advantage of using a generator over solar battery storage. You can choose from a wide variety of models and brands. In contrast to solar batteries, many of these generators are easily available in the market.
The majority of generators can be moved and used wherever you like, and this makes it simple to provide electricity wherever you need it. Just how much fuel you can store, and transport is your only constraint.
Being reliant on external fuel sources is one of the main drawbacks of using a generator. These sources could run out of fuel during a natural disaster or become expensive. Additionally, generators produce unhealthy fumes that can be inhaled. This calls for their placement outside in a well-ventilated area, which may present difficulties in inclement weather.
The fact that the fuel source is free is the main advantage of using a solar-battery combination. As long as the sun is shining and the system is undamaged, that fuel can still be used during a natural disaster. Another advantage a typical gasoline generator cannot match is the quietness and environmental friendliness of a solar with storage solution.
Cost is a drawback for solar systems. Through the decrease in your electric bill and other financial incentives, a solar system can typically pay for itself in a relatively short amount of time. The only benefit of a solar battery is the ability to store energy for later use, but it can be expensive.
Also needed is room for the batteries, which will change depending on the battery you use and how much energy storage you need. These batteries will only get smaller and more compact as technology develops, which is good news.
Gasoline generators can range in price from a few hundred dollars to several thousand dollars, depending on how much energy you need to produce. The cost of installing a battery system in conjunction with a solar panel can vary. A 1,500-watt heater can run for more than 6 hours on stored energy, and that battery costs around $15,000 with installation. The cost of a battery backup system for your entire home, including installation fees, could exceed $100,000.
The federal solar tax credit of 26% generally applies to battery systems where the batteries will be charged solely by solar energy. Commercial systems may be eligible for accelerated depreciation as well. Please keep in mind that before purchasing a system, we strongly recommend that you consult with a tax professional to review your specific situation.
Furthermore, some states provide incentives for battery systems. For the first 30% of the cost of a battery system, Maryland currently offers a state tax credit of up to $5,000 for homeowners and $75,000 for businesses.
Batteries are an excellent source of immediate power that can be used for a few hours to maintain the function of low-power devices such as lights and refrigerators. It is also possible to charge an electric vehicle within a few hours.
If your utility company offers a plan called “time-of-use,” you may be able to store more power in your battery by reducing the amount of energy you use during times of peak demand. When the sun goes down, especially when the power goes out, you will have more power than you normally would.
Even though batteries cost more upfront than generators, they can save you money in the long run because they only make use of clean energy and require very little upkeep or repair.
The price of energy storage is projected to decrease by 8% annually between now and 2022. It is anticipated in the report that the price of batteries will decrease as an increasing number of people use technology to generate their energy at home.
