Solar energy is a great way to save money on your electricity bills. However, it’s essential to understand how your system will work before committing to it.
First, you must figure out how much electricity you use each month. It will help you determine your savings over time and also give you an idea of how long it’ll take to break even on your solar system.
Solar Panels
Solar panels collect clean, renewable energy from sunlight and convert it into electricity. Batteries are typically used to store the electricity generated by solar panels so that you can use them later.

You can also sell the electricity generated by solar panels to the electric grid through a net metering program. It can help you recoup your initial investment in solar panels and provide an additional source of income from your solar system’s power.
Depending on the state and the energy rate plan, you can sell electricity back to the utility company at a higher price than the retail cost of the same amount of power from the grid. In New York, for example, this process is known as “net metering” and allows customers to earn credits for the excess power they produce from their solar systems.
Selecting a location that receives sufficient sun exposure throughout the year is crucial to maximizing the energy output from your solar system. It is particularly true for farm or industrial buildings. These structures can be well suited to using solar power like A&G Electric, as they often have large roof areas that you can use for mounting panels.
Batteries
In a battery, chemical energy is transformed into electrical power. It is how our computers, cell phones, and electric vehicles work.
Batteries are used in many applications, from small hearing aid batteries to giant battery banks that supply power for telephone exchanges and computer data centers. They also power heavy-duty machinery such as forklifts, which must be solid and reliable.
Every battery has a positive electrode (the cathode) and a negative electrode (the anode). An electrolyte separates these and allows ions to move from one electrode to another.
The electrodes are usually made from different materials, and a separator is used to prevent the mixing of the electrolytes while allowing ions to flow between them. It helps the electrons move freely between the electrodes and complete the electrical circuit.
Once the electrons have built up a buildup of ions, they want to move from the cathode to the anode. It is a process called “electronic charge buildup.”
When this happens, electrons create a voltage or potential difference between the two electrodes. The battery’s capacity is measured in mAh or milliampere-hours. Most batteries lose their capacity as they are discharged, and the discharge rate is a measure of this. When a battery is being charged, it must be fed a certain amount of current to charge it fully. This current is measured in mA.
Energy Storage
Storage systems help to smooth out variations in how solar energy flows on the grid. These variations are caused by differences in how much sunlight hits photovoltaic panels or concentrating solar-thermal power (CSP) systems and obstructions like dust, clouds, shadows, and haze.
One way to store excess solar generation is by storing it in batteries, which you can use later. Lithium-ion battery storage systems are the most common energy storage technology today.
However, there are many different types of storage available. Some of these include pumped storage hydropower and compressed air energy storage.
These technologies have the potential to help utilities balance their electricity customer demand with renewable generation supply by charging when there is extra wind or solar power and discharging when there isn’t. Moreover, they can provide frequency regulation and voltage control that helps prevent costly transmission and distribution investments from adding to grid congestion.
Finally, storage can replace existing fossil fuel peaker plants–the dirty and inefficient peaking facilities that operate only during periods of high electricity demand, like during a heat wave or blackouts. These dirty, polluting plants increase air pollution and harm the health of communities that have to live close to them.
In addition, storage can help reduce the cost of renewable energy for residential customers by allowing them to sell their excess solar production back to the grid during high electricity demand times. It can help keep prices low and encourage more people to go solar.
Selling Electricity
Net metering is a process in which electricity customers generate more power from solar panels than they use. They can then sell this extra energy back to the utility company. It helps reduce the strain on the grid during peak hours and means that homes and businesses produce clean energy, which is better for the environment.
The first step in selling your excess solar energy is to find a utility company that offers net metering and get a contract. The amount you will receive depends on the type of meter your home has and the rules and rates set by the electric company in your area.
For example, in New Jersey, customers with a meter with a Cumulative Some states will allow earning money through Solar Renewable Energy Certificates (SRECs). SRECs are certificates that you can sell for every 1,000 kWh of electricity generated by your solar system.
SRECs are a great way to make extra cash while contributing to your state’s renewable energy goals. They are essential to many states’ renewable portfolio standards and help utilities develop green portfolios.
