If you''re like most solar shoppers, you''re considering an energy storage system primarily for resilience: as a source of backup power during outages. Standalone storage may be able to help provide backup power but with one important caveat: if you install storage without solar, you''ll have no way to recharge your battery while the grid is still
What Is Stand-Alone Solar? With stand-alone solar, your power system is insular and not connected to the local power grid. Instead, the solar panels produce energy that travels through the inverter to a power bank or system of solar storage batteries.
Batteries, and other stand-alone equipment, are required for a fully functional off-grid solar system and add to costs as well as maintenance. Grid-tied solar systems are therefore generally cheaper and simpler to install. Your solar panels will often generate more electricity than what you are capable of consuming.
DIYers and people yearning for complete energy independence may choose a stand alone solar array. This off-grid system has no connection to the utility power grid. Off-grid is also suitable for folks living remotely, far from power lines, since the cost of installing transmission and distribution cables is prohibitive by comparison.

Powering your home, vehicle, farm, or cabin with solar energy has never been cheaper. But more options make the switch complicated. Knowing the major differences between them will make your choice easier — and can save you money.
In an on-grid solar system, photovoltaic (PV) panels are connected to the utility grid. During the day, the solar modules supply your home with electricity. The solar array could be rooftop or ground mount.
During the solar panel installation, the PV modules are connected to an inverter. There are several types of solar inverters on the market, but they all do the same thing: convert the direct current (DC) electricity from the sun into the alternating current (AC) that you need to run most household appliances.
If your solar array produces an excess of electricity that you don''t consume, it''s sent to the power grid as AC to supply other homes or businesses. In jurisdictions in the United States where net metering exists, homeowners receive a bill credit for the surplus.
Whether individuals eligible for net metering receive retail or wholesale rates varies from place to place. Later, homeowners "redeem" their credits when they use grid electricity because their solar array is not generating enough energy to meet demand.
However, it''s not correct to think that the utility provides you with a "free" form of solar storage through net metering. You pay a fixed monthly fee for access to the power grid – whether you actually use this service or not.
In some places, electric companies may charge higher rates during peak demand times. Homeowners with solar may soften the sting of higher costs during peak daytime demand because of their solar array offsetting the need for utility electricity.
Since you are connected to the grid, however, power outages also shut down your PV array. This prevents electricians repairing the transmission lines from getting hurt or killed by live voltage sent by your panels.
U.S. states vary widely in the number and extent of federal or state tax breaks, rebates, and other incentives for home solar. For an average U.S. home in 2020, a 6kW solar installation project costs approximately $17,000 (after the federal tax credit).
Through the end of 2020, the federal solar tax credit is equal to 26% of the total installation cost. In 2021, this credit drops to 22%. It will expire after that unless reauthorized by Congress.

Because stand alone systems have no connection to the grid, whatever solar energy your PV cells capture – and you can store in batteries is all you have for power. That is, unless you have another renewable energy source or a fossil fuel-driven generator.
Some people who live off-grid like to combine solar with wind by installing residential wind turbines. The logic is that when there are clouds that decrease solar production, wind is likely going to take up the slack.
There are several online calculators to use when figuring out how much electricity you need to power all the appliances you''d like to. The total amount determines the appropriate size for your battery pack (if you decide to use one). A battery pack is just an interconnected set of batteries.
Another way of looking at it is that, on average, solar batteries cost between $200 and $2,000 each depending on their capacity to store energy. A typical battery pack for an off-grid system could include 12 batteries.
