Investing in an 18kW solar system can result in substantial savings over time. On average, this system can save up to $5,585 per year. Over the 25-year lifetime of the solar panels, the total savings can amount to an impressive $139,613.
One of the key reasons why investing in solar energy is advantageous is the continuously rising cost of electricity. Over the past 40 years, electricity costs have increased by a staggering 270%. This trend is expected to continue, making solar energy an even more attractive option for cost-conscious consumers.

By generating your own electricity with a solar system, you can significantly reduce your reliance on utility companies. The more self-generated electricity you use, the less you have to pay to utility companies, resulting in substantial savings on your monthly electricity bills.
One of the benefits of an 18kW solar system is the opportunity to generate a profit. If your system generates more electricity than you consume, you can sell the excess back to the grid. This allows you to earn money from your solar panels. Based on current electricity costs, you can expect a 20% return on your investment per year.
The typical cost for an 18kW solar system is around $36,000. However, it’s important to note that prices have come down substantially over the past 10 years, making solar systems more affordable and accessible for homeowners and businesses.
If you’re considering adding battery backup to your solar system, it’s crucial to choose the right type of battery. Lead acid and lithium polymer batteries are the most common options.
By using lead acid batteries, an 18kW solar system would require a battery capacity of 216 kWh. In contrast, lithium polymer batteries would only require 113 kWh. Lithium batteries are highly recommended as they have a higher depth of discharge and are more efficient, allowing you to use half as many batteries.
To reduce costs, it is advisable to purchase the batteries and panels together, as this can result in a more cost-effective solution.
If you are planning to build an off-grid solar system, several considerations should be taken into account. To generate sufficient electricity, you would need to purchase 60 or more solar panels. Additionally, you would need 113 kWh worth of lithium polymer batteries to fulfill a full cycle.
The typical cost of batteries required to run an 18kW off-grid solar system is approximately $53,298, making it essential to factor this into your overall budget.
To achieve an 18kW solar system, most panels available on the market are 300 watts each. Therefore, you would need to install 60 or more panels to reach the desired capacity.
